  1. The Equal Access Act: Recent Court Decisions.

    ERIC Educational Resources Information Center

    Bjorklun, Eugene C.

    1989-01-01

    Examines court decisions which led to the passage of the Equal Access Act of 1984. Although the act was designed to clarify the issue over the legality of permitting religious clubs to meet on school property, it may have created more confusion. Concludes that the Supreme Court may have to decide the issue. (SLM)

  2. Advance decisions and the Mental Capacity Act.

    PubMed

    Halliday, Samantha

    This article considers the requirements set out in the Mental Capacity Act 2005 for valid advance decisions. The Act recognizes that an adult with capacity may refuse treatment, including life-sustaining treatment, in advance of losing capacity. If that advance decision is valid and applicable, it will bind health-care professionals, taking effect as if the patient had contemporaneously refused the treatment. However, in cases where the advance decision does not relate to treatment for a progressive disease, it will be extremely difficult for the patient to meet the dual specificity requirement - specifying the treatment to be refused and the circumstances in which that refusal should operate. Moreover, while a patient may explicitly revoke an advance decision while she retains the capacity to do so, the continuing validity of an advance decision may be called into question by the patient implicitly revoking her advance refusal or by a change of circumstance. This article concludes that the key to enabling patients to exercise precedent autonomy will be full and frank discussion of the scope and intentions underlying advance decisions between patients and their health-care professionals.

  10. Mental Capacity and Mental Health Acts part 1: advance decisions.

    PubMed

    Griffith, Richard

    The Department of Health is undertaking a review of the Mental Health Act 1983 code of practice and as part of that review has opened a consultation on what changes should be made. One key area for change is a chapter that provides clearer information about the interface between the Mental Health Act 1983 and the Mental Capacity Act 2005. Both the House of Commons Health Select Committee and the House of Lords Mental Capacity Act Committee have argued that poor understanding of the interface has led to flawed decision making by doctors and nurses. In the first of a short series of articles, Richard Griffith considers the interface between these two important statutes, beginning with advance decisions to refuse treatment (ADRT).

  14. An Evaluation of Iranian Judges’ Decisions about The Act of Embryo Donation

    PubMed Central

    Milanifar, Alireza; Behjati Ardekani, Zohreh; Akhondi, Mohammad Mehdi

    2015-01-01

    Embryo donation was one of the infertility treatment methods introduced to the Iranian legal system in 2003 (Act of Embryo Donation) and its by-law passed in 2005 after nu- merous discussions. Embryo donation is a new legal issue in Iran. No similar act has been previously legis- lated in the legal system; however, on the other hand, the importance of the judicial pro- cedure in its execution cannot be ignored since during this treatment process the infertile couples must refer to the court. In this paper, we analyzed 80 court decisions that concerned permission for embryo do- nation during 2006-2011. The decisions were made for couples who requested this treat- ment and referred to Avicenna Fertility Center (Tehran, Iran). In this study, we analyzed the decisions and regulations for the demands, in addition to the medical and legal view- points of the judges. The differences among the judges’ decisions and in the ways of investigating were discussed. PMID:26246885

  15. To Act or Not to Act: Endocannabinoid/Dopamine Interactions in Decision-Making

    PubMed Central

    Hernandez, Giovanni; Cheer, Joseph F.

    2015-01-01

    Decision-making is an ethologically adaptive construct that is impaired in multiple psychiatric disorders. Activity within the mesocorticolimbic dopamine system has been traditionally associated with decision-making. The endocannabinoid system through its actions on inhibitory and excitatory synapses modulates dopamine activity and decision-making. The aim of this brief review is to present a synopsis of available data obtained when the endocannabinoid system is manipulated and dopamine activity recorded. To this end, we review research using different behavioral paradigms to provide further insight into how this ubiquitous signaling system biases dopamine-related behaviors to regulate decision-making.

  16. The French Space Operation Act: Technical Regulations

    NASA Astrophysics Data System (ADS)

    Trinchero, J. P.; Lazare, B.

    2010-09-01

    The French Space Operation Act(FSOA) stipulates that a prime objective of the National technical regulations is to protect people, property, public health and the environment. Compliance with these technical regulations is mandatory as of 10 December 2010 for space operations by French space operators and for space operations from French territory. The space safety requirements and regulations governing procedures are based on national and international best practices and experience. A critical design review of the space system and procedures shall be carried out by the applicant, in order to verify compliance with the Technical Regulations. An independent technical assessment of the operation is delegated to CNES. The principles applied when drafting technical regulations are as follows: requirements must as far as possible establish the rules according to the objective to be obtained, rather than how it is to be achieved; requirements must give preference to international standards recognised as being the state of the art; requirements must take previous experience into account. Technical regulations are divided into three sections covering common requirements for the launch, control and return of a space object. A dedicated section will cover specific rules to be applied at the Guiana Space Centre. The main topics addressed by the technical regulations are: operator safety management system; study of risks to people, property, public health and the Earth’s environment; impact study on the outer space environment: space debris generated by the operation; planetary protection.

  17. Medical decision making and the Human Rights Act 1998.

    PubMed

    Loughrey, J

    2001-01-01

    At present in the UK, when there is conflict of opinion between relatives and health care professionals regarding the treatment of incompetent patients, the courts generally support the latter over the former. This article examines the potential impact of the Human Rights Act 1998, which incorporates the European Convention on Human Rights into UK law, on this position. The possibility of challenges by relatives to disputed decisions on the grounds of Articles 2,3,8 and 14 is examined in the light of relevant Convention jurisprudence. It concludes that the Act will not necessarily result in relatives' views taking priority over doctors', given that the domestic test of the patient's best interests may not infringe the Convention. However, more account will have to be taken of relatives' views given the requirement for the courts to adopt a rights based analysis and to take a more pro-active role in scrutinising medical decision making.

  6. Effect of regulating anger and sadness on decision-making.

    PubMed

    2016-11-01

    The aim of the current study was to investigate the effects of reappraisal, acceptance, and rumination for regulating anger and sadness on decision-making. Participants (N = 165) were asked to recall two autobiographical events in which they felt intense anger and sadness, respectively. Participants were then instructed to reappraise, accept, ruminate, or not use any strategies to regulate their feelings of anger and sadness. Following this manipulation, risk aversion, and decision-making strategies were measured using a computer-based measure of risk-taking and a simulated real-life decision-making task. Participants who were instructed to reappraise their emotions showed the least anger and sadness, the most adaptive decision-making strategies, but the least risk aversion as compared to the participants in the other conditions. These findings suggest that emotion regulation strategies of negative affective states have an immediate effect on decision-making and risk-taking behaviors. PMID:27438753

    Chowaniec, Małgorzata; Chowaniec, Czesław

    2003-01-01

    In years 1996 and 1997 both the Pension Act and the Social Insurance Act were changed in Poland and as a consequence of this, all the regulations relating to decision making about the inability to work. Having suppressed the so-called disability groups, such terms as permanent or temporary inability to work were introduced. Medical boards deciding on disability were replaced by predicative physicians working for the Social Insurance Department. Recently a rise in number of cases relative to the verification of the decisions passed by the SID and sent by either employer or Social Insurance Departments of district courts to the Department of Forensic Medicine Silesian Academy in Katowice has been observed. The authors have tried to analyse the cause of a rise in the number of appeals to a decision of the SID submitted by the insured.

  2. Medical loss ratio regulation under the Affordable Care Act.

    PubMed

    Harrington, Scott E

    2013-01-01

    The minimum medical loss ratio (MLR) regulations in the Affordable Care Act guarantee that a specific percentage of health insurance premiums is spent on medical care and specified activities to improve health care quality. This paper analyzes the regulations' potential unintended consequences and incentive effects, including: higher medical costs and premiums for some insurers; less innovation to align consumer, provider, and health plan incentives, less consumer choice and increased market concentration; and the risk that insurers will pay rebates if claim costs are lower than projected when premiums are established, despite the regulations' permitted "credibility adjustments." The paper discusses modifications and alternatives to the MLR regulations to help achieve their stated goals with less potential for adverse effects. PMID:23720876

  9. Mechanics Regulates Fate Decisions of Human Embryonic Stem Cells

    PubMed Central

    Sun, Yubing; Villa-Diaz, Luis G.; Lam, Raymond H. W.; Chen, Weiqiang; Krebsbach, Paul H.; Fu, Jianping

    2012-01-01

    Research on human embryonic stem cells (hESCs) has attracted much attention given their great potential for tissue regenerative therapy and fundamental developmental biology studies. Yet, there is still limited understanding of how mechanical signals in the local cellular microenvironment of hESCs regulate their fate decisions. Here, we applied a microfabricated micromechanical platform to investigate the mechanoresponsive behaviors of hESCs. We demonstrated that hESCs are mechanosensitive, and they could increase their cytoskeleton contractility with matrix rigidity. Furthermore, rigid substrates supported maintenance of pluripotency of hESCs. Matrix mechanics-mediated cytoskeleton contractility might be functionally correlated with E-cadherin expressions in cell-cell contacts and thus involved in fate decisions of hESCs. Our results highlighted the important functional link between matrix rigidity, cellular mechanics, and pluripotency of hESCs and provided a novel approach to characterize and understand mechanotransduction and its involvement in hESC function.

  10. Love as a regulative ideal in surrogate decision making.

    PubMed

    Stonestreet, Erica Lucast

    2014-10-01

    This discussion aims to give a normative theoretical basis for a "best judgment" model of surrogate decision making rooted in a regulative ideal of love. Currently, there are two basic models of surrogate decision making for incompetent patients: the "substituted judgment" model and the "best interests" model. The former draws on the value of autonomy and responds with respect; the latter draws on the value of welfare and responds with beneficence. It can be difficult to determine which of these two models is more appropriate for a given patient, and both approaches may seem inadequate for a surrogate who loves the patient. The proposed "best judgment" model effectively draws on the values incorporated in each of the traditional standards, but does so because these values are important to someone who loves a patient, since love responds to the patient as the specific person she is.

  11. Regulated protein kinases and phosphatases in cell cycle decisions

    PubMed Central

    Novak, Bela; Kapuy, Orsolya; Domingo-Sananes, Maria Rosa; Tyson, John J

    2013-01-01

    Many aspects of cell physiology are controlled by protein kinases and phosphatases, which together determine the phosphorylation state of targeted substrates. Some of these target proteins are themselves kinases or phosphatases or other components of a regulatory network characterized by feedback and feed-forward loops. In this review we describe some common regulatory motifs involving kinases, phosphatases, and their substrates, focusing particularly on bistable switches involved in cellular decision processes. These general principles are applied to cell cycle transitions, with special emphasis on the roles of regulated phosphatases in orchestrating progression from one phase to the next of the DNA replication-division cycle.

  12. Safe drinking water act: Amendments, regulations and standards

    SciTech Connect

    Calabrese, E.J.; Gilbert, C.E.; Pastides, H.

    1989-01-01

    This book approaches the topic of safe drinking water by communicating how the EPA has responded to the mandates of Congress. Chapter 1 summarizes what is and will be involved in achieving safe drinking water. Chapter 2 describes the historical development of drinking water regulations. Chapter 3 summarizes the directives of the Safe Drinking Water Act Amendments of 1986. Chapters 4 through 9 discuss each phase of the regulatory program in turn. Specific problems associated with volatile organic chemicals, synthetic organics, inorganic chemicals, and microbiological contaminants are assessed in Chapter 4 and 5. The unique characteristics of radionuclides and their regulation are treated in Chapter 6. The disinfection process and its resultant disinfection by-products are presented in Chapter 7. The contaminant selection process and the additional contaminants to be regulated by 1989 and 1991 and in future years are discussed in Chapters 8 and 9. EPA's Office of Drinking Water's Health Advisory Program is explained in Chapter 10. The record of public water system compliance with the primary drinking water regulations is detailed in Chapter 11. Chapter 12 offers a nongovernmental perspective on the general quality of drinking water and how this is affected by a wide range of drinking water treatment technologies. Separate abstracts are processed for 5 chapters in this book for inclusion in the appropriate data bases.

  16. Adaptive Equilibrium Regulation: A Balancing Act in Two Timescales

    PubMed Central

    Boker, Steven M.

    2015-01-01

    An equilibrium involves a balancing of forces. Just as one maintains upright posture in standing or walking, many self-regulatory and interpersonal behaviors can be framed as a balancing act between an ever changing environment and within-person processes. The emerging balance between person and environment, the equilibria, are dynamic and adaptive in response to development and learning. A distinction is made between equilibrium achieved solely due to a short timescale balancing of forces and a longer timescale preferred equilibrium which we define as a state towards which the system slowly adapts. Together, these are developed into a framework that this article calls Adaptive Equilibrium Regulation (ÆR), which separates a regulatory process into two timescales: a faster regulation that automatically balances forces and a slower timescale adaptation process that reconfigures the fast regulation so as to move the system towards its preferred equilibrium when an environmental force persists over the longer timescale. This way of thinking leads to novel models for the interplay between multiple timescales of behavior, learning, and development. PMID:27066197

  11. Homeostatic Regulation of Memory Systems and Adaptive Decisions

    PubMed Central

    Mizumori, Sheri JY; Jo, Yong Sang

    2013-01-01

    While it is clear that many brain areas process mnemonic information, understanding how their interactions result in continuously adaptive behaviors has been a challenge. A homeostatic-regulated prediction model of memory is presented that considers the existence of a single memory system that is based on a multilevel coordinated and integrated network (from cells to neural systems) that determines the extent to which events and outcomes occur as predicted. The “multiple memory systems of the brain” have in common output that signals errors in the prediction of events and/or their outcomes, although these signals differ in terms of what the error signal represents (e.g., hippocampus: context prediction errors vs. midbrain/striatum: reward prediction errors). The prefrontal cortex likely plays a pivotal role in the coordination of prediction analysis within and across prediction brain areas. By virtue of its widespread control and influence, and intrinsic working memory mechanisms. Thus, the prefrontal cortex supports the flexible processing needed to generate adaptive behaviors and predict future outcomes. It is proposed that prefrontal cortex continually and automatically produces adaptive responses according to homeostatic regulatory principles: prefrontal cortex may serve as a controller that is intrinsically driven to maintain in prediction areas an experience-dependent firing rate set point that ensures adaptive temporally and spatially resolved neural responses to future prediction errors. This same drive by prefrontal cortex may also restore set point firing rates after deviations (i.e. prediction errors) are detected. In this way, prefrontal cortex contributes to reducing uncertainty in prediction systems. An emergent outcome of this homeostatic view may be the flexible and adaptive control that prefrontal cortex is known to implement (i.e. working memory) in the most challenging of situations. Compromise to any of the prediction circuits should result

  20. Overview of the regulation of hazardous chemicals: SDWA (Safe Drinking Water Act), RCRA (Resource Conservation and Recovery Act), and CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act)

    SciTech Connect

    Baes, C.F. III

    1989-01-01

    The regulation of nonradioactive hazardous chemicals is carried out under a number of federal environmental laws that regulate either hazardous products, substances, or wastes. Because each law is intended to provide protection from different classes of substances (e.g., wastes vs products) or protect different media (e.g., air, water, land), the standards and levels of protection for different hazardous chemicals may be different. Nevertheless, one agency -- the Environmental Protection Agency (EPA) -- has primary responsibility for both promulgating regulations mandated by Congress under the various statutes and enforcement of the regulations. One overriding principal underlies the maze of complex regulations that govern the transport, treatment, storage, and disposal of hazardous substances: protect human health and the environment. It is beyond the scope of this talk to comprehensively examine all of the regulations and standards that govern the management of hazardous chemicals. Instead this discussion will focus on three statutes, the Safe Drinking Water Act (SDWA), the Resource Conservation and Recovery Act (RCRA), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), that together provide a basis for a basic understanding of the approach that the EPA takes to regulating hazardous chemicals.

    Thoughtful decision-making to resolve socioscientific issues is central to science, technology, society, and environment (STSE) education. One approach for attaining this goal involves fostering students' decision-making processes. Thus, the present study explores whether the application of decision-making strategies, combined with reflections on the decision-making processes of others, enhances decision-making competence. In addition, this study examines whether this process is supported by elements of self-regulated learning, i.e., self-reflection regarding one's own performance and the setting of goals for subsequent tasks. A computer-based training program which involves the resolution of socioscientific issues related to sustainable development was developed in two versions: with and without elements of self-regulated learning. Its effects on decision-making competence were analyzed using a pre test-post test follow-up control-group design (N = 242 high school students). Decision-making competence was assessed using an open-ended questionnaire that focused on three facets: consideration of advantages and disadvantages, metadecision aspects, and reflection on the decision-making processes of others. The findings suggest that students in both training groups incorporated aspects of metadecision into their statements more often than students in the control group. Furthermore, both training groups were more successful in reflecting on the decision-making processes of others. The students who received additional training in self-regulated learning showed greater benefits in terms of metadecision aspects and reflection, and these effects remained significant two months later. Overall, our findings demonstrate that the application of decision-making strategies, combined with reflections on the decision-making process and elements of self-regulated learning, is a fruitful approach in STSE education.

  12. Act quickly, decide later: long-latency visual processing underlies perceptual decisions but not reflexive behavior.

    Humans largely guide their behavior by their visual representation of the world. Recent studies have shown that visual information can trigger behavior within 150 msec, suggesting that visually guided responses to external events, in fact, precede conscious awareness of those events. However, is such a view correct? By using a texture discrimination task, we show that the brain relies on long-latency visual processing in order to guide perceptual decisions. Decreasing stimulus saliency leads to selective changes in long-latency visually evoked potential components reflecting scene segmentation. These latency changes are accompanied by almost equal changes in simple RTs and points of subjective simultaneity. Furthermore, we find a strong correlation between individual RTs and the latencies of scene segmentation related components in the visually evoked potentials, showing that the processes underlying these late brain potentials are critical in triggering a response. However, using the same texture stimuli in an antisaccade task, we found that reflexive, but erroneous, prosaccades, but not antisaccades, can be triggered by earlier visual processes. In other words: The brain can act quickly, but decides late. Differences between our study and earlier findings suggesting that action precedes conscious awareness can be explained by assuming that task demands determine whether a fast and unconscious, or a slower and conscious, representation is used to initiate a visually guided response.

  13. Auxin acts independently of DELLA proteins in regulating gibberellin levels.

    Reid, James B; Davidson, Sandra E; Ross, John J

    2011-03-01

    Shoot elongation is a vital process for plant development and productivity, in both ecological and economic contexts. Auxin and bioactive gibberellins (GAs), such as GA1, play critical roles in the control of elongation, along with environmental and endogenous factors, including other hormones such as the brassinosteroids. The effect of auxins, such as indole-3-acetic acid (IAA), is at least in part mediated by its effect on GA metabolism, since auxin up-regulates biosynthesis genes such as GA 3-oxidase and GA 20-oxidase and down regulates GA catabolism genes such as GA 2-oxidases, leading to elevated levels of bioactive GA 1. In our recent paper, we have provided evidence that this action of IAA is largely independent of DELLA proteins, the negative regulators of GA action, since the auxin effects are still present in the DELLA-deficient la cry-s genotype of pea. This was a crucial issue to resolve, since like auxin, the DELLAs also promote GA 1 synthesis and inhibit its deactivation. DELLAs are deactivated by GA, and thereby mediate a feedback system by which bioactive GA regulates its own level. However, our recent results, in themselves, do not show the generality of the auxin-GA relationship across species and phylogenetic groups or across different tissue types and responses. Further, they do not touch on the ecological benefits of the auxin-GA interaction. These issues are discussed below as well as the need for the development of suitable experimental systems to allow this process to be examined. PMID:21358281

  16. The application of genetic information for regulatory standard setting under the clean air act: a decision-analytic approach.

    2008-08-01

    In 2002, the U.S. Environmental Protection Agency (EPA) released an "Interim Policy on Genomics," stating a commitment to developing guidance on the inclusion of genetic information in regulatory decision making. This statement was followed in 2004 by a document exploring the potential implications. Genetic information can play a key role in understanding and quantifying human susceptibility, an essential step in many of the risk assessments used to shape policy. For example, the federal Clean Air Act (CAA) requires EPA to set National Ambient Air Quality Standards (NAAQS) for criteria pollutants at levels to protect even sensitive populations from adverse health effects with an adequate margin of safety. Asthmatics are generally regarded as a sensitive population, yet substantial research gaps in understanding genetic susceptibility and disease have hindered quantitative risk analysis. This case study assesses the potential role of genomic information regarding susceptible populations in the NAAQS process for fine particulate matter (PM(2.5)) under the CAA. In this initial assessment, we model the contribution of a single polymorphism to asthma risk and mortality risk; however, multiple polymorphisms and interactions (gene-gene and gene-environment) are known to play key roles in the disease process. We show that the impact of new information about susceptibility on estimates of population risk or average risk derived from large epidemiological studies depends on the circumstances. We also suggest that analysis of a single polymorphism, or other risk factor such as health status, may or may not change estimates of individual risk enough to alter a particular regulatory decision, but this depends on specific characteristics of the decision and risk information. We also show how new information about susceptibility in the context of the NAAQS for PM(2.5) could have a large impact on the estimated distribution of individual risk. This would occur if a group were

  16. Regulation of Proliferation-Survival Decisions during Tumor Cell Hypoxia

    PubMed Central

    Schmaltz, Cornelius; Hardenbergh, Patricia Harrigan; Wells, Audrey; Fisher, David E.

    1998-01-01

    Hypoxia may influence tumor biology in paradoxically opposing ways: it is lethal as a direct stress trigger, yet hypoxic zones in solid tumors harbor viable cells which are particularly resistant to treatment and contribute importantly to disease relapse. To examine mechanisms underlying growth-survival decisions during hypoxia, we have compared genetically related transformed and untransformed fibroblast cells in vitro for proliferation, survival, clonogenicity, cell cycle, and p53 expression. Hypoxia induces G0/G1 arrest in primary fibroblasts but triggers apoptosis in oncogene-transformed derivatives. Unexpectedly, the mechanism of apoptosis is seen to require accumulated acidosis and is rescued by enhanced buffering. The direct effect of hypoxia under nonacidotic conditions is unique to transformed cells in that they override the hypoxic G0/G1 arrest of primary cells. Moreover, when uncoupled from acidosis, hypoxia enhances tumor cell viability and clonogenicity relative to normoxia. p53 is correspondingly upregulated in response to hypoxia-induced acidosis but downregulated during hypoxia without acidosis. Hypoxia may thus produce both treatment resistance and a growth advantage. Given strong evidence that hypoxic regions in solid tumors are often nonacidotic (G. Helmlinger, F. Yuan, M. Dellian, and R. K. Jain, Nat. Med. 3:177–182, 1997), this behavior may influence relapse and implicates such cells as potentially important therapeutic targets. PMID:9566903

  17. Regulating Emotions during Difficult Multiattribute Decision Making: The Role of Pre-Decisional Coherence Shifting

    PubMed Central

    Carpenter, Stephanie M.; Yates, J. Frank; Preston, Stephanie D.; Chen, Lydia

    2016-01-01

    Almost all real-life decisions entail attribute conflict; every serious choice alternative is better than its competitors on some attribute dimensions but worse on others. In pre-decisional “coherence shifting,” the decision maker gradually softens that conflict psychologically to the point where one alternative is seen as dominant over its competitors, or nearly so. Specifically, weaknesses of the eventually chosen alternative come to be perceived as less severe and less important while its strengths seem more desirable and significant. The research described here demonstrates that difficult multiattribute decision problems are aversive and that pre-decisional coherence shifting aids individuals in regulating that emotional discomfort. Across three studies, attribute conflict was confirmed to be aversive (Study 1), and skin conductance responses and ratings of decision difficulty both decreased in participants who coherence shifted (Study 2). Coherence shifting was also diminished among decision makers who were depleted of regulatory resources, known to be required for common emotion regulation mechanisms. Further, coherence shifting was shown to be relatively common among people who reported strong suppression tendencies in everyday emotion regulation (Study 3). Overall, the data suggest that, at least in part, coherence shifting serves as a tool that helps decision makers manage the pre-decisional discomfort generated by attribute conflict. Theoretical and practical implications are discussed. PMID:26986752

  18. Technology diffusion and environmental regulation: Evidence from electric power plants under the Clean Air Act

    NASA Astrophysics Data System (ADS)

    Frey, Elaine F.

    Even though environmental policy can greatly affect the path of technology diffusion, the economics literature contains limited empirical evidence of this relationship. My research will contribute to the available evidence by providing insight into the technology adoption decisions of electric generating firms. Since policies are often evaluated based on the incentives they provide to promote adoption of new technologies, it is important that policy makers understand the relationship between technological diffusion and regulation structure to make informed decisions. Lessons learned from this study can be used to guide future policies such as those directed to mitigate climate change. I first explore the diffusion of scrubbers, a sulfur dioxide (SO 2) abatement technology, in response to federal market-based regulations and state command-and-control regulations. I develop a simple theoretical model to describe the adoption decisions of scrubbers and use a survival model to empirically test the theoretical model. I find that power plants with strict command-and-control regulations have a high probability of installing a scrubber. These findings suggest that although market-based regulations have encouraged diffusion, many scrubbers have been installed because of state regulatory pressure. Although tradable permit systems are thought to give firms more flexibility in choosing abatement technologies, I show that interactions between a permit system and pre-existing command-and-control regulations can limit that flexibility. In a separate analysis, I explore the diffusion of combined cycle (CC) generating units, which are natural gas-fired generating units that are cleaner and more efficient than alternative generating units. I model the decision to consider adoption of a CC generating unit and the extent to which the technology is adopted in response to environmental regulations imposed on new sources of pollutants. To accomplish this, I use a zero-inflated Poisson

    2015-11-01

    Over the past 20 years there has been a growing interest in the neural underpinnings of cost/benefit decision-making. Recent studies with animal models have made considerable advances in our understanding of how different prefrontal, striatal, limbic and monoaminergic circuits interact to promote efficient risk/reward decision-making, and how dysfunction in these circuits underlies aberrant decision-making observed in numerous psychiatric disorders. This review will highlight recent findings from studies exploring these questions using a variety of behavioral assays, as well as molecular, pharmacological, neurophysiological, and translational approaches. We begin with a discussion of how neural systems related to decision subcomponents may interact to generate more complex decisions involving risk and uncertainty. This is followed by an overview of interactions between prefrontal-amygdala-dopamine and habenular circuits in regulating choice between certain and uncertain rewards and how different modes of dopamine transmission may contribute to these processes. These data will be compared with results from other studies investigating the contribution of some of these systems to guiding decision-making related to rewards vs. punishment. Lastly, we provide a brief summary of impairments in risk-related decision-making associated with psychiatric disorders, highlighting recent translational studies in laboratory animals.

    There are always conflicting goals in the management of large water courses. However, by involving stakeholders actively in the planning and decision-making processes, it is possible to work together toward commonly acceptable solutions. In this article, we describe how we applied interactive multicriteria decision analysis (MCDA) in a collaborative process which aimed at an ecologically, socially, and economically sustainable water course regulation policy. The stakeholders' opinions about the alternative regulation schemes and the relative importance of their impacts were elicited with the HIPRE software. Altogether, 20 personal interactive decision analysis interviews (DAIs) were carried out with the stakeholders. Our experience suggests that the DAIs can considerably improve the quality and efficiency of the collaborative planning process. By improving communication and understanding of the decision situation in the steering group, the approach helped to develop a consensus solution in a case having strong conflicts of interest. In order to gain the full benefits of the MCDA approach, interactive preference elicitation is vital. It is also essential to integrate the approach tightly into the planning and decision-making process. The project's home pages are available to the public at http://www.paijanne.hut.fi/.

  5. Should the model for risk-informed regulation be game theory rather than decision theory?

    PubMed

    Bier, Vicki M; Lin, Shi-Woei

    2013-02-01

    Risk analysts frequently view the regulation of risks as being largely a matter of decision theory. According to this view, risk analysis methods provide information on the likelihood and severity of various possible outcomes; this information should then be assessed using a decision-theoretic approach (such as cost/benefit analysis) to determine whether the risks are acceptable, and whether additional regulation is warranted. However, this view ignores the fact that in many industries (particularly industries that are technologically sophisticated and employ specialized risk and safety experts), risk analyses may be done by regulated firms, not by the regulator. Moreover, those firms may have more knowledge about the levels of safety at their own facilities than the regulator does. This creates a situation in which the regulated firm has both the opportunity-and often also the motive-to provide inaccurate (in particular, favorably biased) risk information to the regulator, and hence the regulator has reason to doubt the accuracy of the risk information provided by regulated parties. Researchers have argued that decision theory is capable of dealing with many such strategic interactions as well as game theory can. This is especially true in two-player, two-stage games in which the follower has a unique best strategy in response to the leader's strategy, as appears to be the case in the situation analyzed in this article. However, even in such cases, we agree with Cox that game-theoretic methods and concepts can still be useful. In particular, the tools of mechanism design, and especially the revelation principle, can simplify the analysis of such games because the revelation principle provides rigorous assurance that it is sufficient to analyze only games in which licensees truthfully report their risk levels, making the problem more manageable. Without that, it would generally be necessary to consider much more complicated forms of strategic behavior (including

  6. Can Contrast Effects Regulate Emotions? A Follow-Up Study of Vital Loss Decisions

    Liu, Xianyun; Luo, Jing

    2012-01-01

    Although many studies focus on the how contrast effects can impact cognitive evaluations, the question of whether emotions are regulated by such contrast effects is still the subject of considerable debate, especially in the study of loss-related decisions. To address this gap in the literature, we designed three decision making loss conditions: (i) both losses are trivial (TT), (ii) one loss is trivial and the other loss is vital (TV), or (iii) one loss is trivial and the other loss is routine (TR). In study 1, which compared the difference between the negative emotion ratings in TT and TV, we found that negative emotions were affected by the contrast effects. In study 2, which compared the difference between the importance of trivial options in TT and TV, we found that the contrast effects differentially changed the importance of trivial options in the two conditions, which in turn down-regulated negative emotions. In study 3, the impact of decision difficulty was controlled by predetermining the items to be lost. In this study, we found that, when comparing the differences between the negative emotions of losing trivial options in TV and TR, the contrast effects still modulated the loss-related emotions. We concluded that the contrast effects could down-regulate emotions. To our knowledge, this is the first demonstration that contrast effects can alleviate negative affect in loss-related decision making. This study will enrich and extend the literature on emotion regulation theory, and it will provide a new cost-effective mitigation strategy for regulating negative emotions. PMID:22905170

    Ending its 27-year stranglehold on proposals for federal pure food and drug legislation, Congress passed the Pure Food and Drug Act and its companion bill, the Meat Inspection Act, on June 30, 1906. An unprecedented convergence of consumer, scientific, and industrial support in 1906 prompted such action; most industries even planned for it, hoping regulation would restore the competitiveness of their products on weak foreign and domestic markets. The ways in which these interests converged, and the reasons therefore, suggest a change in their relationships to each other and with the federal government as America headed into the twentieth century.

  10. New paradigms for conserved, multifactorial, cis-acting regulation of meiotic recombination.

    PubMed

    Wahls, Wayne P; Davidson, Mari K

    2012-11-01

    How do cells position the Spo11 (Rec12)-dependent initiation of meiotic recombination at hotspots? The mechanisms are poorly understood and a prevailing view is that they differ substantially between phylogenetic groups. However, recent work discovered that individual species have multiple different DNA sequence-specific, protein-DNA complexes that regulate (and are essential for the activation of) recombination hotspots. The cis-acting elements function combinatorially with documented examples of synergism, antagonism and redundancy. Furthermore, we provide evidence that all currently well-defined modules of this multifactorial, cis-acting regulation are conserved functionally between taxa whose latest common ancestor occurred more than 1 billion years ago. Functionally conserved components include the ATF/CREB-family heterodimer Atf1-Pcr1 and its CRE-like DNA site M26, the CCAAT-box-binding complex Php2-Php3-Php5 and the CCAAT-box, and the zinc-finger protein Rst2 and its Oligo-C motif. The newfound multiplicity, functional redundancy and conservation of cis-acting controls constitute a paradigm shift with broad implications. They provide compelling evidence that most meiotic recombination is, like transcription, regulated by sequence-specific protein-DNA complexes. And the new findings provide important mechanistic insight, such as a solution to the conundrum that Prdm9 is a 'master regulator' of--yet is dispensable for--hotspot activity in mammals.

    Among other things, this Act amends the Maharashtra (India) Felling of Trees (Regulation) Act, 1964, to authorize the Tree Officer to order the planting of trees in any land (other than government-designated drought land) that he thinks does not contain an adequate number of trees. Owners and occupiers of the land must comply with the order, after being given a reasonable opportunity to be heard. If they do not comply, they can be charged for expenses incurred in having the trees planted. In 1989 the government of West Bengal enacted The Indian Forest (West Bengal Amendment) Act, 1989 (No. 22 of 1988) (Calcutta Gazette, Extraordinary, Part III, 3 February 1989). This Act increases the punishment for various infractions of the Indian Forest Act, 1927, as applied to West Bengal and inserts new language relating to the power of officers to stop and search vehicles; the ability of the state government to seize contraband and related tools, vehicles, boats, and cattle; and punishment for abetting offenses delineated by the Act.

  12. Regulation of neuronal lineage decisions by the HES-related bHLH protein REF-1.

    PubMed

    Lanjuin, Anne; Claggett, Julia; Shibuya, Mayumi; Hunter, Craig P; Sengupta, Piali

    2006-02-01

    Members of the HES subfamily of bHLH proteins play crucial roles in neural patterning via repression of neurogenesis. In C. elegans, loss-of-function mutations in ref-1, a distant nematode-specific member of this subfamily, were previously shown to cause ectopic neurogenesis from postembryonic lineages. However, while the vast majority of the nervous system in C. elegans is generated embryonically, the role of REF-1 in regulating these neural lineage decisions is unknown. Here, we show that mutations in ref-1 result in the generation of multiple ectopic neuron types derived from an embryonic neuroblast. In wild-type animals, neurons derived from this sublineage are present in a left/right symmetrical manner. However, in ref-1 mutants, while the ectopically generated neurons exhibit gene expression profiles characteristic of neurons on the left, they are present only on the right side. REF-1 functions in a Notch-independent manner to regulate this ectopic lineage decision. We also demonstrate that loss of REF-1 function results in defective differentiation of an embryonically generated serotonergic neuron type. These results indicate that REF-1 functions in both Notch-dependent and independent pathways to regulate multiple developmental decisions in different neuronal sublineages.

  13. Fault-rupture hazards, the Alquist-Priolo Fault Hazard Act, and siting decisions in California

    1994-06-01

    The Alquist-Priolo Act was enacted in 1971 and became operational in 1972 as an aftermath of the 1971 San Fernando Earthquake. State Senator Alfred E. Alquist and Assemblyman Paul V. Priolo are to be commended for moving rapidly toward improved earthquake loss reduction. Unfortunately, those who were worried about the concept that too much knowledge will adversely impact the economy of California were more influential and politically astute than those who support the concept that proper use of science and technology can reduce the loss of life as well as the astronomically high dollar losses associated with earthquakes. The estimated dollar loss of over $5.9 billion for the 1989 Loma Prieta earthquake (McNutt and Sydnor, 1990) clearly indicates that the Alquist-Priolo Act may be of little value, even along a strike-slip plate boundary, as none of the damage or losses resulted from surface fault rupture. Similar notable absence of fault rupture damage is reported for the 1987 Whittier earthquake (over $100 million loss; Shakal, 1987) and the 1983 Coalinga earthquake ($31 million loss; Tierney, 1985). The damage, property loss and loss of life from these earthquakes resulted from factors which are not addressed by the Alquist-Priolo Act. Even though considerable fault-rupture damage occurred during the 1992 Landers earthquake, most of the problems were associated with rupture of lifelines, such as water mains, and not collapse of structures for human occupancy.

  18. Behavioral contagion during learning about another agent's risk-preferences acts on the neural representation of decision-risk.

    PubMed

    Suzuki, Shinsuke; Jensen, Emily L S; Bossaerts, Peter; O'Doherty, John P

    2016-04-01

    Our attitude toward risk plays a crucial role in influencing our everyday decision-making. Despite its importance, little is known about how human risk-preference can be modulated by observing risky behavior in other agents at either the behavioral or the neural level. Using fMRI combined with computational modeling of behavioral data, we show that human risk-preference can be systematically altered by the act of observing and learning from others' risk-related decisions. The contagion is driven specifically by brain regions involved in the assessment of risk: the behavioral shift is implemented via a neural representation of risk in the caudate nucleus, whereas the representations of other decision-related variables such as expected value are not affected. Furthermore, we uncover neural computations underlying learning about others' risk-preferences and describe how these signals interact with the neural representation of risk in the caudate. Updating of the belief about others' preferences is associated with neural activity in the dorsolateral prefrontal cortex (dlPFC). Functional coupling between the dlPFC and the caudate correlates with the degree of susceptibility to the contagion effect, suggesting that a frontal-subcortical loop, the so-called dorsolateral prefrontal-striatal circuit, underlies the modulation of risk-preference. Taken together, these findings provide a mechanistic account for how observation of others' risky behavior can modulate an individual's own risk-preference. PMID:27001826

    Notch signaling critically mediates various hematopoietic lineage decisions and is induced in mammals by Notch ligands that are classified into 2 families, Delta-like (Delta-like-1, -3 and -4) and Jagged (Jagged1 and Jagged2), based on structural homology with both Drosophila ligands Delta and Serrate, respectively. Because the functional differences between mammalian Notch ligands were still unclear, we have investigated their influence on early human hematopoiesis and show that Jagged2 affects hematopoietic lineage decisions very similarly as Delta-like-1 and -4, but very different from Jagged1. OP9 coculture experiments revealed that Jagged2, like Delta-like ligands, induces T-lineage differentiation and inhibits B-cell and myeloid development. However, dose-dependent Notch activation studies, gene expression analysis, and promoter activation assays indicated that Jagged2 is a weaker Notch1-activator compared with the Delta-like ligands, revealing a Notch1 specific signal strength hierarchy for mammalian Notch ligands. Strikingly, Lunatic-Fringe– mediated glycosylation of Notch1 potentiated Notch signaling through Delta-like ligands and also Jagged2, in contrast to Jagged1. Thus, our results reveal a unique role for Jagged1 in preventing the induction of T-lineage differentiation in hematopoietic stem cells and show an unexpected functional similarity between Jagged2 and the Delta-like ligands.

    2013-01-01

    Objective To present a microsimulation model that addresses the methodological challenge of estimating the firm decision to self-insure. Methodology The model considers the risk that the firm bears when self-insuring and the opportunity to mitigate that risk by purchasing stop-loss insurance. The model makes use of a structural, utility maximization framework to account for numerous aspects of the firm decision, and a multinomial probit to reproduce the elasticity of the firm's demand for health insurance. Findings and Conclusions Our simulations provide three important conclusions. First, they project significant increases in self-insurance rates among small firms--presumably induced by the desire to avoid ACA's rate-banding and risk adjustment regulations—only if generous stop-loss policies become widely available. Second, they show that this increase would be due to this hypothetical adoption of widespread, generous reinsurance by the market and not by passage of the ACA. Third, even with a substantial increase of self-insurance rates among small firms, they project negligible adverse selection in the exchanges, as indicated by our finding that the increase in exchange premium is less than 0.5% when assuming very generous stop-loss policies after implementation of the ACA.

  6. New paradigms for conserved, multifactorial, cis-acting regulation of meiotic recombination

    2012-01-01

    How do cells position the Spo11 (Rec12)-dependent initiation of meiotic recombination at hotspots? The mechanisms are poorly understood and a prevailing view is that they differ substantially between phylogenetic groups. However, recent work discovered that individual species have multiple different DNA sequence-specific, protein–DNA complexes that regulate (and are essential for the activation of) recombination hotspots. The cis-acting elements function combinatorially with documented examples of synergism, antagonism and redundancy. Furthermore, we provide evidence that all currently well-defined modules of this multifactorial, cis-acting regulation are conserved functionally between taxa whose latest common ancestor occurred more than 1 billion years ago. Functionally conserved components include the ATF/CREB-family heterodimer Atf1-Pcr1 and its CRE-like DNA site M26, the CCAAT-box-binding complex Php2-Php3-Php5 and the CCAAT-box, and the zinc-finger protein Rst2 and its Oligo-C motif. The newfound multiplicity, functional redundancy and conservation of cis-acting controls constitute a paradigm shift with broad implications. They provide compelling evidence that most meiotic recombination is, like transcription, regulated by sequence-specific protein–DNA complexes. And the new findings provide important mechanistic insight, such as a solution to the conundrum that Prdm9 is a ‘master regulator’ of—yet is dispensable for—hotspot activity in mammals.

    The context of care in assertive community treatment (ACT) can be precarious and generate ethical issues involving the principles of autonomy and paternalism. This focus group study examined case managers' situated accounts of moral reasoning. Our findings show how they expressed strong moral obligation towards helping the clients. Their moral reasoning reflected a paternalistic position where, on different occasions, the potential benefits of their interventions would be prioritised at the expense of protecting the clients' personal autonomy. The case managers' reasoning emphasised situational awareness, but there was a risk of supporting paternalistic interventions and denying the clients' right to autonomy. PMID:26440868

    1998-06-01

    Prenatal and preconceptual testing and screening programs provide information on the basis of which people can choose to avoid the birth of children likely to face disabilities. Some disabilities advocates have objected to such programs and to the decisions made within them, on the grounds that measures taken to avoid the birth of children with disabilities have an "expressive force" that conveys messages disrespectful to people with disabilities. Assessing such a claim requires careful attention to general considerations relating meaning, intention, and social practices; it has only begun to receive such attention. Building on work by Allen Buchanan, who has challenged this claim, I further consider the disabilities advocates' objection, ultimately concluding that it is misplaced; neither individual actions nor general practices of this type necessarily express disrespectful messages.

    Elsewhere in this issue of the Federal Register, the IRS is issuing temporary regulations relating to mental health parity requirements imposed on group health plans. These requirements were added to the Internal Revenue Code by section 1532 of the Taxpayer Relief Act of 1997. The IRS is issuing the temporary regulations at the same time that the Pension and Welfare Benefits Administration of the U.S. Department of Labor and the Health Care Financing Administration of the U.S. Department of Health and Human Services are issuing substantially similar interim final regulations relating to mental health parity requirements added by the Mental Health Parity Act of 1996 to the Employee Retirement Income Security Act of 1974 and the Public Health Service Act. The temporary regulations provide guidance to employers and group health plans relating to the new mental health parity requirements. The text of those temporary regulations also serves as the text of these proposed regulations.

    Lys63-linked polyubiquitination of RIG-I is essential in antiviral immune defense, yet the molecular mechanism that negatively regulates this critical step is poorly understood. Here, we report that USP21 acts as a novel negative regulator in antiviral responses through its ability to bind to and deubiquitinate RIG-I. Overexpression of USP21 inhibited RNA virus–induced RIG-I polyubiquitination and RIG-I–mediated interferon (IFN) signaling, whereas deletion of USP21 resulted in elevated RIG-I polyubiquitination, IRF3 phosphorylation, IFN-α/β production, and antiviral responses in MEFs in response to RNA virus infection. USP21 also restricted antiviral responses in peritoneal macrophages (PMs) and bone marrow–derived dendritic cells (BMDCs). USP21-deficient mice spontaneously developed splenomegaly and were more resistant to VSV infection with elevated production of IFNs. Chimeric mice with USP21-deficient hematopoietic cells developed virus-induced splenomegaly and were more resistant to VSV infection. Functional comparison of three deubiquitinases (USP21, A20, and CYLD) demonstrated that USP21 acts as a bona fide RIG-I deubiquitinase to down-regulate antiviral response independent of the A20 ubiquitin-editing complex. Our studies identify a previously unrecognized role for USP21 in the negative regulation of antiviral response through deubiquitinating RIG-I. PMID:24493797

    2011-05-01

    To achieve the aims of the Affordable Care Act, state and federal regulators must construct an effective system of risk adjustment, one that protects health insurers that attract a disproportionate share of patients with poor health risks. This brief, which summarizes a Commonwealth Fund–supported conference of leading risk adjustment experts, explores the challenges regulators will face, considers the consequences of the law's risk adjustment provisions, and analyzes the merits of different risk adjustment strategies. Among other recommendations, the brief suggests that regulators use diagnostic rather than only demographic risk measures, that they allow states some but limited flexibility to tailor risk adjustment methods to local circumstances, and that they phase in the use of risk transfer payments to give insurers more time to predict and understand the full effects of risk adjustment.

  14. Regulation of toxic pollutants under the Clean Water Act: EPA's ten-year rulemaking nears completion

    1983-01-01

    Whether it's footdragging, or compliance is impossible, the Environmental Protection Agency (EPA) usually fails to meet its deadlines for issuing regulations. The best-known case is probably EPA's 10-year struggle to establish regulatory controls on toxic pollutants under the Clean Water Act. The developmental process is reviewed from the initial statutory framework (enacted in 1948) and the effluent limitations amendments (legislated in 1972), through its litigation history, to an analysis of the federal district court's three substantive opinions delivered during 1982. The author considers the possibility of legislative intervention because deadlines for compliance have been issued but the regulations have not. He concludes that without Toxics Consent Decree litigation, the toxic pollutant control program might have become a reality. EPA's toxic pollutant control regulations as of April 1, 1983, are tabulated. 129 references, 4 tables.

  15. The decision to exclude agricultural and domestic workers from the 1935 Social Security Act.

    PubMed

    DeWitt, Larry

    2010-01-01

    The Social Security Act of 1935 excluded from coverage about half the workers in the American economy. Among the excluded groups were agricultural and domestic workers-a large percentage of whom were African Americans. This has led some scholars to conclude that policymakers in 1935 deliberately excluded African Americans from the Social Security system because of prevailing racial biases during that period. This article examines both the logic of this thesis and the available empirical evidence on the origins of the coverage exclusions. The author concludes that the racial-bias thesis is both conceptually flawed and unsupported by the existing empirical evidence. The exclusion of agricultural and domestic workers from the early program was due to considerations of administrative feasibility involving tax-collection procedures. The author finds no evidence of any other policy motive involving racial bias.

  16. Numb is not a critical regulator of Notch-mediated cell fate decisions in the developing chick inner ear

    The Notch signaling pathway controls differentiation of hair cells and supporting cells in the vertebrate inner ear. Here, we have investigated whether Numb, a known regulator of Notch activity in Drosophila, is involved in this process in the embryonic chick. The chicken homolog of Numb is expressed throughout the otocyst at early stages of development and is concentrated at the basal pole of the cells. It is asymmetrically allocated at some cell divisions, as in Drosophila, suggesting that it could act as a determinant inherited by one of the two daughter cells and favoring adoption of a hair-cell fate. To test the implication of Numb in hair cell fate decisions and the regulation of Notch signaling, we used different methods to overexpress Numb at different stages of inner ear development. We found that sustained or late Numb overexpression does not promote hair cell differentiation, and Numb does not prevent the reception of Notch signaling. Surprisingly, none of the Numb-overexpressing cells differentiated into hair cells, suggesting that high levels of Numb protein could interfere with intracellular processes essential for hair cell survival. However, when Numb was overexpressed early and more transiently during ear development, no effect on hair cell formation was seen. These results suggest that in the inner ear at least, Numb does not significantly repress Notch activity and that its asymmetric distribution in dividing precursor cells does not govern the choice between hair cell and supporting cell fates.

    2014-01-01

    To maintain tissue homeostasis, cell fate decisions within stem cell lineages have to respond to the needs of the tissue. This coordination of lineage choices with regenerative demand remains poorly characterized. Here we identify a signal from enteroendocrine cells (EEs) that controls lineage specification in the Drosophila intestine. We find that EEs secrete Slit, a ligand for the Robo2 receptor in stem cells (ISCs) that limits ISC commitment to the endocrine lineage, establishing negative feedback control of EE regeneration. We further show that this lineage decision is made within ISCs and requires induction of the transcription factor Prospero in ISCs. Our work identifies a new function for the conserved Slit/Robo pathway in the regulation of adult stem cells, establishing negative feedback control of ISC lineage specification as a critical strategy to preserve tissue homeostasis. Our results further amend the current understanding of cell fate commitment within the Drosophila ISC lineage. PMID:24931602

  20. The nexus between decision making and emotion regulation: a review of convergent neurocognitive substrates.

    PubMed

    Mitchell, Derek G V

    2011-02-01

    Emotional information, such as reward or punishment, gains rapid and often preferential access to neurocognitive resources. This ability to quickly evaluate and integrate emotion-related information is thought to benefit a range of behaviours critical for survival. Conversely, the improper use of, or preoccupation with, emotional information is associated with disruptions in functioning and psychiatric disorders. Optimally, an organism utilizes emotional information when it is significant, and minimizes its influence when it is not. Recently, similar regions of prefrontal cortex have been identified that are associated with regulating both behavioural conflict (motor response selection or inhibition) and affective conflict (emotional representation and awareness). In this review, data will be examined that concerns this convergence between decision making (modulating what we do) and emotion regulation (modulating how we feel) and an informal model will be proposed linking these processes at a neurocognitive level. The studies reviewed collectively support the conclusion that overlapping areas of prefrontal cortex perform similar computations whether the functional objective is to modulate an operant response, or an emotional one. Specifically, the idea is raised that key aspects of decision making and emotion regulation are bound by a common functional objective in which internal representations of conditioned stimuli and reinforcers are modulated to facilitate optimal behaviour or states. Emphasis is placed on dorsomedial, dorsolateral, ventrolateral, and ventromedial regions of prefrontal cortex. PMID:21055420

    Objective This article describes the rigorous development process and initial feedback of the PRE-ACT (Preparatory Education About Clinical Trials) web-based- intervention designed to improve preparation for decision making in cancer clinical trials. Methods The multi-step process included stakeholder input, formative research, user testing and feedback. Diverse teams (researchers, advocates and developers) participated including content refinement, identification of actors, and development of video scripts. Patient feedback was provided in the final production period and through a vanguard group (N = 100) from the randomized trial. Results Patients/advocates confirmed barriers to cancer clinical trial participation, including lack of awareness and knowledge, fear of side effects, logistical concerns, and mistrust. Patients indicated they liked the tool’s user-friendly nature, the organized and comprehensive presentation of the subject matter, and the clarity of the videos. Conclusion The development process serves as an example of operationalizing best practice approaches and highlights the value of a multi-disciplinary team to develop a theory-based, sophisticated tool that patients found useful in their decision making process. Practice implications Best practice approaches can be addressed and are important to ensure evidence-based tools that are of value to patients and supports the usefulness of a process map in the development of e-health tools.

  3. ATH1 and KNAT2 proteins act together in regulation of plant inflorescence architecture.

    PubMed

    2012-02-01

    The inflorescence of flowering plants is a highly organized structure, not only contributing to plant reproductive processes, but also constituting an important part of the entire plant morphology. Previous studies have revealed that the class-I KNOTTED1-like homeobox (KNOX) genes BREVIPEDICELLUS (BP or KNAT1), KNAT2, and KNAT6 play essential roles in inflorescence architecture. Pedicel morphology is known to contribute greatly to inflorescence architecture, and BP negatively regulates KNAT2 and KNAT6 to ensure that pedicels have a normal upward-pointing orientation. These findings indicate that a genetic network exists in controlling pedicel orientation, but how this network functions in the developmental process remains elusive. Here it is reported that the ARABIDOPSIS THALIANA HOMEOBOX GENE1 (ATH1) gene, which belongs to the BELL1-like homeodomain gene family, is a new member participating in regulating pedicel orientation in the class-I KNOX network. In a genetic screening for suppressors of isoginchaku-2D, a gain-of-function ASYMMETRIC LEAVES2 mutant that displays downward-pointing pedicels, a suppressor mutant was obtained. Characterization of this mutant revealed that the mutation corresponds to ATH1. Genetic analysis indicated that ATH1 acts mainly in the KNAT2 pathway. Yeast two-hybrid and bimolecular fluorescence complementation assays demonstrated that ATH1 physically interacts with KNAT2. The data indicate that the ATH1-KNAT2 complex acts redundantly with KNAT6, both of which are negatively regulated by BP during pedicel development.

    1992-12-31

    In the Clean Air Act Amendments of 1977, Congress directed the Environmental Protection Agency (EPA) to regulate all radioactive pollutants, including those emitted from facilities licensed and regulated under the Atomic Energy Act (AEA) by the Nuclear Regulatory Commission (NRC). Thus began the era of so-called {open_quotes}dual regulation.{close_quotes} Thirteen years later, that era ended with the passage of section 112(d)(9) of the Clean Air Act Amendments of 1990, which authorized the EPA to refrain from regulating any category of NRC-licensed facility if it found that NRC regulation was adequate to protect public health. This story of how Congress reversed regulatory policy is actually a story more about nuclear power than air pollution. Dual regulation was authorized in 1977 because of two concerns: fears about the public health risks associated with the nation`s growing commitment to nuclear power and doubts about the integrity of nuclear regulation by the NRC. Although neither of these concerns had abated by 1990, the legislative process was so adroitly manipulated by the proponents of nuclear power that Congress, unwittingly, restored the NRC`s regulatory monopoly.

    Multivesicular bodies (MVBs) are unique endosomes containing vesicles in the lumens and play essential roles in many eukaryotic cellular processes. The Arabidopsis LYST INTERACTING PROTEIN 5 (LIP5), a positive regulator of MVB biogenesis, has critical roles in biotic and abiotic stress responses. However, whether the abscisic acid (ABA) signaling is involved in LIP5-mediated stress response is largely unknown. Here, we report that LIP5 functions in regulating ABA signaling and drought response in Arabidopsis. Analyses of a LIP5 promoter-β-glucuronidase (GUS) construct revealed substantial GUS activity in whole seedlings. The expression of LIP5 was induced by ABA and drought, and overexpression of LIP5 led to ABA hypersensitivity, enhanced stomatal closure, reduced water loss, and, therefore, increased drought tolerance. On the contrary, LIP5 knockdown mutants showed ABA-insensitive phenotypes and reduced drought tolerance; suggesting that LIP5 acts in regulating ABA response. Further analysis using a fluorescent dye revealed that ABA and water stress induced cell endocytosis or vesicle trafficking in a largely LIP5-dependent manner. Furthermore, expression of several drought- or ABA-inducible marker genes was significantly down-regulated in the lip5 mutant seedlings. Collectively, our data suggest that LIP5 positively regulates drought tolerance through ABA-mediated cell signaling. PMID:27313589

    Highlights: • Identification of cis elements responsible for SamDC expression by in silico analysis. • qPCR analysis of SamDC expression to abiotic and biotic stress treatments. • Detection of SamDC regulators using identified cis-elements as probe by EMSA. • Southwestern Blot analysis to predict the size of the trans-acting factors. - Abstract: Abiotic stress affects the growth and productivity of crop plants; to cope with the adverse environmental conditions, plants have developed efficient defense machinery comprising of antioxidants like phenolics and flavonoids, and osmolytes like polyamines. SamDC is a key enzyme in the polyamine biosynthesis pathway in plants. In our present communication we have done in silico analysis of the promoter region of SamDC to look for the presence of different cis-regulatory elements contributing to its expression. Based on the presence of different cis-regulatory elements we completed comparative analysis of SamDC gene expression in rice lamina of IR-29 and Nonabokra by qPCR in response to the abiotic stress treatments of salinity, drought, cold and the biotic stress treatments of ABA and light. Additionally, to explore the role of the cis-regulatory elements in regulating the expression of SamDC gene in plants we comparatively analyzed the binding of rice nuclear proteins prepared from IR-29 and Nonabokra undergoing various stress treatments. The intensity of the complex formed was low and inducible in IR-29 in contrast to Nonabokra. Southwestern blot analysis helped in predicting the size of the trans-acting factors binding to these cis-elements. To our knowledge this is the first report on the comprehensive analysis of SamDC gene expression in rice and identification of the trans-acting factors regulating its expression.

    This "Legal Briefing" column covers recent legal developments involving patient decision aids.This topic has been the subject of recent articles in JCE. It is included in the 2010 Patient Protection and Affordable Care Act. And it has received significant attention in the biomedical literature, including a new book, a thematic issue of Health Affairs, and a recent article in the New England Journal of Medicine. Moreover, physicians and health systems across the United States are increasingly integrating decision aids into their clinical practice. Both federal and state laws play a significant role in promoting this expanded use. On the other hand, concerns about liability could stymie development and implementation. We categorize legal developments concerning patient decision aids into the following five sections: 1. Development of decision aids. 2. Effectiveness of decision aids. 3. Federal regulation of decision aids. 4. State regulation of decision aids. 5. Legal concerns regarding decision aids.

    The Coal Mine Health and Safety Act of 1969 has contributed to the decline in mine productivity, which must be weighed against safer working conditions for the miners. There may be some overstatement of the benefits if only fatalities are considered, however, because there was an increase in non-fatal accidents after 1970. Safety regulations have forced the closure of some small mines and raised some questions about the tradeoffs necessary when work safety reduces competition. A review of pertinent legislation, a hedonic wage-differential model, and the effects of union wage policy are applied to these questions. 4 tables. (DCK)

    Preaxial polydactyly (PPD) is a common limb malformation in human. A number of polydactylous mouse mutants indicate that misexpression of Shh is a common requirement for generating extra digits. Here we identify a translocation breakpoint in a PPD patient and a transgenic insertion site in the polydactylous mouse mutant sasquatch (Ssq). The genetic lesions in both lie within the same respective intron of the LMBR1/Lmbr1 gene, which resides ≈1 Mb away from Shh. Genetic analysis of Ssq reveals that the Lmbr1 gene is incidental to the phenotype and that the mutation directly interrupts a cis-acting regulator of Shh. This regulator is most likely the target for generating PPD mutations in human. PMID:12032320

    In May 2014, the European Union Parliament and Council published a new regulation on clinical trials on medicinal products for human use, which is designed to replace Directive 2001/20/EC. It will not come into effect until 2016. Nevertheless, it is essential to examine its relationship with national legislation, i.e. the Jardé Act, whose implementation has been delayed pending publication of the European regulation. The Giens workshop identified and examined the various issues that this relationship is bound to raise. In particular, it looked at trial methodology assessment procedures, the working relationship between the French National Agency of Drug Safety and Health Products (Agence Nationale de Sécurité du Médicament et des Produits de Santé, ANSM) and ethics committees during the authorization application evaluation phase, review of post-authorization/registration studies on medicinal products and medical devices, and data transparency.

    Guidance for determining the sensitizing potential of chemicals is available in EC Regulation No. 1272/2008 Classification, Labeling, and Packaging of Substances; REACH guidance from the European Chemicals Agency; and the United Nations Globally Harmonized System (GHS). We created decision trees for evaluating potential skin and respiratory sensitizers. Our approach (1) brings all the regulatory information into one brief document, providing a step-by-step method to evaluate evidence that individual chemicals or mixtures have sensitizing potential; (2) provides an efficient, uniform approach that promotes consistency when evaluations are done by different reviewers; (3) provides a standard way to convey the rationale and information used to classify chemicals. We applied this approach to more than 50 chemicals distributed among 11 evaluators with varying expertise. Evaluators found the decision trees easy to use and recipients (product stewards) of the analyses found that the resulting documentation was consistent across users and met their regulatory needs. Our approach allows for transparency, process management (e.g., documentation, change management, version control), as well as consistency in chemical hazard assessment for REACH, EC Regulation No. 1272/2008 Classification, Labeling, and Packaging of Substances and the GHS.

    Recent public-opinion polls indicate that Americans have shown a decline in support for animal experimentation, and several reports suggest a relationship between people's knowledge of animal welfare regulations and their attitudes toward animal research. Therefore, this study was designed to assess respondent's knowledge of several provisions in the Animal Welfare Act (AWA) and Animal Welfare Regulations (AWR), and determine whether exposure to elements of this legislation would influence an individual's attitudes toward the use of animals in research. A survey was used to assess knowledge of animal research regulations and attitudes toward animal research from a sample of individuals recruited through Amazon's Mechanical Turk crowdsourcing marketplace. Results from study 1 confirmed the hypothesis that respondents had little knowledge of various federal regulations that govern animal research activities. Data from study 2 revealed that exposure to elements of the AWA and AWR influenced participants' attitudes toward the use of animals in research. These results suggest that providing information to the general public about the AWA and AWR that protect laboratory animals from abuse and neglect may help alleviate concerns about using animals in research settings.

    Hormonal regulation of gene expression by androgen receptor (AR) is tightly controlled by many transcriptional cofactors, including pioneer factors FOXA1 and GATA2, which, however, exhibit distinct expression patterns and functional roles in prostate cancer. Here, we examined how FOXA1, GATA2 and AR crosstalk and regulate hormone-dependent gene expression in prostate cancer cells. Chromatin immunoprecipitation sequencing analysis revealed that FOXA1 reprograms both AR and GATA2 cistrome by preferably recruiting them to FKHD-containing genomic sites. By contrast, GATA2 is unable to shift AR or FOXA1 to GATA motifs. Rather, GATA2 co-occupancy enhances AR and FOXA1 binding to nearby ARE and FKHD sites, respectively. Similarly, AR increases, but not reprograms, GATA2 and FOXA1 cistromes. Concordantly, GATA2 and AR strongly enhance the transcriptional program of each other, whereas FOXA1 regulates GATA2- and AR-mediated gene expression in a context-dependent manner due to its reprogramming effects. Taken together, our data delineated for the first time the distinct mechanisms by which GATA2 and FOXA1 regulate AR cistrome and suggest that FOXA1 acts upstream of GATA2 and AR in determining hormone-dependent gene expression in prostate cancer.

    Neurotrophins, via activation of Trk receptor tyrosine kinases, serve as mitogens, survival factors and regulators of arborization during retinal development. Brain-derived neurotrophic factor (BDNF) and TrkB regulate neuronal arborization and survival in late retinal development. However, TrkB is expressed during early retinal developmet where its functions are unclear. To assess TrkB/BDNF actions in the early chick retina, replication-incompetent retroviruses were utilized to over-express a dominant negative truncated form of TrkB (trunc TrkB), or BDNF and effects were assessed at E15. Clones expressing trunc TrkB were smaller than controls, and proliferation and apoptosis assays suggest that decreased clone size correlated with increased cell death when BDNF/TrkB signaling was impaired. Analysis of clonal composition revealed that trunc TrkB over-expression decreased photoreceptor numbers (41%) and increased cell numbers in the middle third of the inner nuclear layer (INL) (23%). Conversely, BDNF over-expression increased photoreceptor numbers (25%) and decreased INL numbers (17%). Photoreceptors over-expressing trunc TrkB demonstrated no increase in apoptosis nor abnormalities in lamination suggesting that TrkB activation is not required for photoreceptor cell survival or migration. These studies suggest that TrkB signaling regulates commitment to and/or differentiation of photoreceptor cells from retinal progenitor cells, identifying a novel role for TrkB/BDNF in regulating cell fate decisions.

  20. The Neuropeptide Allatostatin A Regulates Metabolism and Feeding Decisions in Drosophila

    Coordinating metabolism and feeding is important to avoid obesity and metabolic diseases, yet the underlying mechanisms, balancing nutrient intake and metabolic expenditure, are poorly understood. Several mechanisms controlling these processes are conserved in Drosophila, where homeostasis and energy mobilization are regulated by the glucagon-related adipokinetic hormone (AKH) and the Drosophila insulin-like peptides (DILPs). Here, we provide evidence that the Drosophila neuropeptide Allatostatin A (AstA) regulates AKH and DILP signaling. The AstA receptor gene, Dar-2, is expressed in both the insulin and AKH producing cells. Silencing of Dar-2 in these cells results in changes in gene expression and physiology associated with reduced DILP and AKH signaling and animals lacking AstA accumulate high lipid levels. This suggests that AstA is regulating the balance between DILP and AKH, believed to be important for the maintenance of nutrient homeostasis in response to changing ratios of dietary sugar and protein. Furthermore, AstA and Dar-2 are regulated differentially by dietary carbohydrates and protein and AstA-neuronal activity modulates feeding choices between these types of nutrients. Our results suggest that AstA is involved in assigning value to these nutrients to coordinate metabolic and feeding decisions, responses that are important to balance food intake according to metabolic needs.

    Alternative mRNA splicing is a major mechanism for gene regulation and transcriptome diversity. Despite the extent of the phenomenon, the regulation and specificity of the splicing machinery are only partially understood. Adenosine-to-inosine (A-to-I) RNA editing of pre-mRNA by ADAR enzymes has been linked to splicing regulation in several cases. Here we used bioinformatics approaches, RNA-seq and exon-specific microarray of ADAR knockdown cells to globally examine how ADAR and its A-to-I RNA editing activity influence alternative mRNA splicing. Although A-to-I RNA editing only rarely targets canonical splicing acceptor, donor, and branch sites, it was found to affect splicing regulatory elements (SREs) within exons. Cassette exons were found to be significantly enriched with A-to-I RNA editing sites compared with constitutive exons. RNA-seq and exon-specific microarray revealed that ADAR knockdown in hepatocarcinoma and myelogenous leukemia cell lines leads to global changes in gene expression, with hundreds of genes changing their splicing patterns in both cell lines. This global change in splicing pattern cannot be explained by putative editing sites alone. Genes showing significant changes in their splicing pattern are frequently involved in RNA processing and splicing activity. Analysis of recently published RNA-seq data from glioblastoma cell lines showed similar results. Our global analysis reveals that ADAR plays a major role in splicing regulation. Although direct editing of the splicing motifs does occur, we suggest it is not likely to be the primary mechanism for ADAR-mediated regulation of alternative splicing. Rather, this regulation is achieved by modulating trans-acting factors involved in the splicing machinery. PMID:23474544

  3. Confinement regulates complex biochemical networks: initiation of blood clotting by "diffusion acting".

    PubMed

    This study shows that environmental confinement strongly affects the activation of nonlinear reaction networks, such as blood coagulation (clotting), by small quantities of activators. Blood coagulation is sensitive to the local concentration of soluble activators, initiating only when the activators surpass a threshold concentration, and therefore is regulated by mass transport phenomena such as flow and diffusion. Here, diffusion was limited by decreasing the size of microfluidic chambers, and it was found that microparticles carrying either the classical stimulus, tissue factor, or a bacterial stimulus, Bacillus cereus, initiated coagulation of human platelet-poor plasma only when confined. A simple analytical argument and numerical model were used to describe the mechanism for this phenomenon: confinement causes diffusible activators to accumulate locally and surpass the threshold concentration. To interpret the results, a dimensionless confinement number, Cn, was used to describe whether a stimulus was confined, and a Damköhler number, Da(2), was used to describe whether a subthreshold stimulus could initiate coagulation. In the context of initiation of coagulation by bacteria, this mechanism can be thought of as "diffusion acting", which is distinct from "diffusion sensing". The ability of confinement and diffusion acting to change the outcome of coagulation suggests that confinement should also regulate other biological "on" and "off" processes that are controlled by thresholds.

    Successful participation in competitive endurance activities requires continual regulation of muscular work rate in order to maximise physiological performance capacities, meaning that individuals must make numerous decisions with regards to the muscular work rate selected at any point in time. Decisions relating to the setting of appropriate goals and the overall strategic approach to be utilised are made prior to the commencement of an event, whereas tactical decisions are made during the event itself. This review examines current theories of decision-making in an attempt to explain the manner in which regulation of muscular work is achieved during athletic activity. We describe rational and heuristic theories, and relate these to current models of regulatory processes during self-paced exercise in an attempt to explain observations made in both laboratory and competitive environments. Additionally, we use rational and heuristic theories in an attempt to explain the influence of the presence of direct competitors on the quality of the decisions made during these activities. We hypothesise that although both rational and heuristic models can plausibly explain many observed behaviours in competitive endurance activities, the complexity of the environment in which such activities occur would imply that effective rational decision-making is unlikely. However, at present, many proposed models of the regulatory process share similarities with rational models. We suggest enhanced understanding of the decision-making process during self-paced activities is crucial in order to improve the ability to understand regulation of performance and performance outcomes during athletic activity.

  7. Polycomb Group Protein Pcgf6 Acts as a Master Regulator to Maintain Embryonic Stem Cell Identity

    2016-01-01

    The polycomb repressive complex 1 (PRC1) is a multi-subunit complex that plays critical roles in the epigenetic modulation of gene expression. Here, we show that the PRC1 component polycomb group ring finger 6 (Pcgf6) is required to maintain embryonic stem cell (ESC) identity. In contrast to canonical PRC1, Pcgf6 acts as a positive regulator of transcription and binds predominantly to promoters bearing active chromatin marks. Pcgf6 is expressed at high levels in ESCs, and knockdown reduces the expression of the core ESC regulators Oct4, Sox2, and Nanog. Conversely, Pcgf6 overexpression prevents downregulation of these factors and impairs differentiation. In addition, Pcgf6 enhanced reprogramming in both mouse and human somatic cells. The genomic binding profile of Pcgf6 is highly similar to that of trithorax group proteins, but not of PRC1 or PRC2 complexes, suggesting that Pcgf6 functions atypically in ESCs. Our data reveal novel roles for Pcgf6 in directly regulating Oct4, Nanog, Sox2, and Lin28 expression to maintain ESC identity. PMID:27247273

    Abelson family kinases (Abls) are key regulators of cell behavior and the cytoskeleton during development and in leukemia. Abl’s SH3, SH2, and tyrosine kinase domains are joined via a linker to an F-actin–binding domain (FABD). Research on Abl’s roles in cell culture led to several hypotheses for its mechanism of action: 1) Abl phosphorylates other proteins, modulating their activity, 2) Abl directly regulates the cytoskeleton via its cytoskeletal interaction domains, and/or 3) Abl is a scaffold for a signaling complex. The importance of these roles during normal development remains untested. We tested these mechanistic hypotheses during Drosophila morphogenesis using a series of mutants to examine Abl’s many cell biological roles. Strikingly, Abl lacking the FABD fully rescued morphogenesis, cell shape change, actin regulation, and viability, whereas kinase-dead Abl, although reduced in function, retained substantial rescuing ability in some but not all Abl functions. We also tested the function of four conserved motifs in the linker region, revealing a key role for a conserved PXXP motif known to bind Crk and Abi. We propose that Abl acts as a robust multidomain scaffold with different protein motifs and activities contributing differentially to diverse cellular behaviors. PMID:27385341

  11. Regulating outdoor advertisement boards; employing spatial decision support system to control urban visual pollution

    Unmanaged placement, size, location, structure and contents of outdoor advertisement boards have resulted in severe urban visual pollution and deterioration of the socio-physical living environment in urban centres of Pakistan. As per the regulatory instruments, the approval decision for a new advertisement installation is supposed to be based on the locational density of existing boards and their proximity or remoteness to certain land- uses. In cities, where regulatory tools for the control of advertisement boards exist, responsible authorities are handicapped in effective implementation due to the absence of geospatial analysis capacity. This study presents the development of a spatial decision support system (SDSS) for regularization of advertisement boards in terms of their location and placement. The knowledge module of the proposed SDSS is based on provisions and restrictions prescribed in regulatory documents. While the user interface allows visualization and scenario evaluation to understand if the new board will affect existing linear density on a particular road and if it violates any buffer restrictions around a particular land use. Technically the structure of the proposed SDSS is a web-based solution which includes open geospatial tools such as OpenGeo Suite, GeoExt, PostgreSQL, and PHP. It uses three key data sets including road network, locations of existing billboards and building parcels with land use information to perform the analysis. Locational suitability has been calculated using pairwise comparison through analytical hierarchy process (AHP) and weighted linear combination (WLC). Our results indicate that open geospatial tools can be helpful in developing an SDSS which can assist solving space related iterative decision challenges on outdoor advertisements. Employing such a system will result in effective implementation of regulations resulting in visual harmony and aesthetic improvement in urban communities.

  12. atonal regulates neurite arborization but does not act as a proneural gene in the Drosophila brain

    Drosophila atonal (ato) is the proneural gene of the chordotonal organs (CHOs) in the peripheral nervous system (PNS) and the larval and adult photoreceptor organs. Here, we show that ato is expressed at multiple stages during the development of a lineage of central brain neurons that innervate the optic lobes and are required for eclosion. A novel fate mapping approach shows that ato is expressed in the embryonic precursors of these neurons and that its expression is reactivated in third instar larvae (L3). In contrast to its function in the PNS, ato does not act as a proneural gene in the embryonic brain. Instead, ato performs a novel function, regulating arborization during larval and pupal development by interacting with Notch.

  13. Enhancer of zeste acts as a major developmental regulator of Ciona intestinalis embryogenesis

    ABSTRACT The paradigm of developmental regulation by Polycomb group (PcG) proteins posits that they maintain silencing outside the spatial expression domains of their target genes, particularly of Hox genes, starting from mid embryogenesis. The Enhancer of zeste [E(z)] PcG protein is the catalytic subunit of the PRC2 complex, which silences its targets via deposition of the H3K27me3 mark. Here, we studied the ascidian Ciona intestinalis counterpart of E(z). Ci-E(z) is detected by immunohistochemistry as soon as the 2- and 4-cell stages as a cytoplasmic form and becomes exclusively nuclear thereafter, whereas the H3K27me3 mark is detected starting from the gastrula stage and later. Morpholino invalidation of Ci-E(z) leads to the total disappearance of both Ci-E(z) protein and its H3K27me3 mark. Ci-E(z) morphants display a severe phenotype. Strikingly, the earliest defects occur at the 4-cell stage with the dysregulation of cell positioning and mitotic impairment. At later stages, Ci-E(z)-deficient embryos are affected by terminal differentiation defects of neural, epidermal and muscle tissues, by the failure to form a notochord and by the absence of caudal nerve. These major phenotypic defects are specifically rescued by injection of a morpholino-resistant Ci-E(z) mRNA, which restores expression of Ci-E(z) protein and re-deposition of the H3K27me3 mark. As observed by qPCR analyses, Ci-E(z) invalidation leads to the early derepression of tissue-specific developmental genes, whereas late-acting developmental genes are generally down-regulated. Altogether, our results suggest that Ci-E(z) plays a major role during embryonic development in Ciona intestinalis by silencing early-acting developmental genes in a Hox-independent manner.

    According to expectancy-value models of self-regulation, people are motivated to act in ways they expect to be useful to them. For instance, people are motivated to run when they believe running is useful, even when they have nothing to run away from. Similarly, we propose an expectancy-value model of emotion regulation, according to which people are motivated to emote in ways they expect to be useful to them, regardless of immediate contextual demands. For instance, people may be motivated to get angry when they believe anger is useful, even when there is nothing to be angry about. In 5 studies, we demonstrate that leading people to expect an emotion to be useful increased their motivation to experience that emotion (Studies 1-5), led them to up-regulate the experience of that emotion (Studies 3-4), and led to emotion-consistent behavior (Study 4). Our hypotheses were supported when we manipulated the expected value of anxiety (Study 1) and anger (Studies 2-5), both consciously (Studies 1-4) and unconsciously (Study 5). We discuss the theoretical and pragmatic implications of the proposed model.

    Background Human genes undergo various patterns of pre-mRNA splicing across different tissues. Such variation is primarily regulated by trans-acting factors that bind on exonic and intronic cis-acting RNA elements (CAEs). Here we report a computational method to mechanistically identify cis-acting RNA elements that contribute to the tissue-specific alternative splicing pattern. This method is an extension of our previous model, SplicingModeler, which predicts the significant CAEs that contribute to the splicing differences between two tissues. In this study, we introduce tissue-specific functional levels estimation step, which allows evaluating regulatory functions of predicted CAEs that are involved in more than two tissues. Results Using a publicly available Affymetrix Genechip® Human Exon Array dataset, our method identifies 652 cis-acting RNA elements (CAEs) across 11 human tissues. About one third of predicted CAEs can be mapped to the known RBP (RNA binding protein) binding sites or match with other predicted exonic splicing regulator databases. Interestingly, the vast majority of predicted CAEs are in intronic regulatory regions. A noticeable exception is that many exonic elements are found to regulate the alternative splicing between cerebellum and testes. Most identified elements are found to contribute to the alternative splicing between two tissues, while some are important in multiple tissues. This suggests that genome-wide alternative splicing patterns are regulated by a combination of tissue-specific cis-acting elements and "general elements" whose functional activities are important but differ across multiple tissues. Conclusion In this study, we present a model-based computational approach to identify potential cis-acting RNA elements by considering the exon splicing variation as the combinatorial effects of multiple cis-acting regulators. This methodology provides a novel evaluation on the functional levels of cis-acting RNA elements by estimating

    Polar transport of the plant hormone auxin controls many aspects of plant growth and development. A number of synthetic compounds have been shown to block the process of auxin transport by inhibition of the auxin efflux carrier complex. These synthetic auxin transport inhibitors may act by mimicking endogenous molecules. Flavonoids, a class of secondary plant metabolic compounds, have been suggested to be auxin transport inhibitors based on their in vitro activity. The hypothesis that flavonoids regulate auxin transport in vivo was tested in Arabidopsis by comparing wild-type (WT) and transparent testa (tt4) plants with a mutation in the gene encoding the first enzyme in flavonoid biosynthesis, chalcone synthase. In a comparison between tt4 and WT plants, phenotypic differences were observed, including three times as many secondary inflorescence stems, reduced plant height, decreased stem diameter, and increased secondary root development. Growth of WT Arabidopsis plants on naringenin, a biosynthetic precursor to those flavonoids with auxin transport inhibitor activity in vitro, leads to a reduction in root growth and gravitropism, similar to the effects of synthetic auxin transport inhibitors. Analyses of auxin transport in the inflorescence and hypocotyl of independent tt4 alleles indicate that auxin transport is elevated in plants with a tt4 mutation. In hypocotyls of tt4, this elevated transport is reversed when flavonoids are synthesized by growth of plants on the flavonoid precursor, naringenin. These results are consistent with a role for flavonoids as endogenous regulators of auxin transport.

  18. Progesterone acts via progesterone receptors A and B to regulate breast cancer resistance protein expression.

    The breast cancer resistance protein (BCRP; ABCG2) is an ATP-dependent efflux multidrug transporter that belongs to the G family of half-transporters that consist of six transmembrane-spanning domains and must homodimerize to form the active membrane transporter. It is expressed in the apical plasma membrane domain of the small intestine, endothelium, and liver, where it has been shown to play an important role in limiting drug absorption and distribution and in enhancing drug clearance, respectively. BCRP is also expressed in the apical membrane of mammary alveolar epithelia, where it mediates efflux of substrates into milk, and in the placental syncytiotro-phoblasts, where it reduces fetal exposure to these substrates. BCRP substrates include numerous drugs (topotecan, nitrofurantoin, cimetidine) as well as food carcinogens (2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine) and the vitamins riboflavin and folic acid. BCRP expression is regulated by a number of nuclear transcription factors, including the peroxisome proliferator-activated receptor-gamma and Hif-1. This issue of Molecular Pharmacology includes a study (p. 845) now conclusively demonstrating that progesterone acts via the progesterone A and B receptors to regulate BCRP expression in a placental cell line.

    dsRNA-dependent protein kinase R (PKR) is a ubiquitously expressed enzyme well known for its roles in immune response. Upon binding to viral dsRNA, PKR undergoes autophosphorylation, and the phosphorylated PKR (pPKR) regulates translation and multiple signaling pathways in infected cells. Here, we found that PKR is activated in uninfected cells, specifically during mitosis, by binding to dsRNAs formed by inverted Alu repeats (IRAlus). While PKR and IRAlu-containing RNAs are segregated in the cytosol and nucleus of interphase cells, respectively, they interact during mitosis when nuclear structure is disrupted. Once phosphorylated, PKR suppresses global translation by phosphorylating the α subunit of eukaryotic initiation factor 2 (eIF2α). In addition, pPKR acts as an upstream kinase for c-Jun N-terminal kinase and regulates the levels of multiple mitotic factors such as CYCLINS A and B and POLO-LIKE KINASE 1 and phosphorylation of HISTONE H3. Disruption of PKR activation via RNAi or expression of a transdominant-negative mutant leads to misregulation of the mitotic factors, delay in mitotic progression, and defects in cytokinesis. Our study unveils a novel function of PKR and endogenous dsRNAs as signaling molecules during the mitosis of uninfected cells. PMID:24939934

    Neuropeptide Y (NPY), a brain neuromodulator that has been strongly implicated in the regulation of energy balance, also acts centrally to inhibit sympathetic nerve activity (SNA); however, the site and mechanism of action are unknown. In chloralose-anaesthetized female rats, nanoinjection of NPY into the paraventricular nucleus of the hypothalamus (PVN) dose-dependently suppressed lumbar SNA (LSNA) and its baroreflex regulation, and these effects were blocked by prior inhibition of NPY Y1 or Y5 receptors. Moreover, PVN injection of Y1 and Y5 receptor antagonists in otherwise untreated rats increased basal and baroreflex control of LSNA, indicating that endogenous NPY tonically inhibits PVN presympathetic neurons. The sympathoexcitation following blockade of PVN NPY inhibition was eliminated by prior PVN nanoinjection of the melanocortin 3/4 receptor inhibitor SHU9119. Moreover, presympathetic neurons, identified immunohistochemically using cholera toxin b neuronal tract tracing from the rostral ventrolateral medulla (RVLM), express NPY Y1 receptor immunoreactivity, and patch-clamp recordings revealed that both NPY and α-melanocyte-stimulating hormone (α-MSH) inhibit and stimulate, respectively, PVN-RVLM neurons. Collectively, these data suggest that PVN NPY inputs converge with α-MSH to influence presympathetic neurons. Together these results identify endogenous NPY as a novel and potent inhibitory neuromodulator within the PVN that may contribute to changes in SNA that occur in states associated with altered energy balance, such as obesity and pregnancy.

    National legislations represent one of the main factors influencing access to assisted reproduction treatment. The Italian situation in the last decade is an example of how the treatment of patients for preimplantation genetic diagnosis (PGD) was more dependent on regulators than on medical choices. This report analysed how the changes in Italian regulation affected the number of PGD referrals to this study centre, as well as their decision to opt for cross-border reproductive care (CBRC). The analysis showed that during the period in which PGD was actually not performed because of the restriction imposed by the Italian law on IVF (from 24 February 2004 to 7 May 2009) there was a significant decrease in the number of referrals asking for PGD (2.5% of total referrals) compared with the previous years (3.3%; P < 0.025) and following years when PGD was legalized (5.1%; P < 0.001). The number of couples opting for CBRC had an opposite trend, reaching a maximum when PGD was banned from Italian centres (55 couples), whereas after the readmission of PGD, only eight couples went abroad for treatment. Concomitantly, since May 2009, the proportion of couples performing a PGD cycle in this centre has constantly increased. PMID:24268726

  6. Allowance trading under the Clean Air Act: Who should regulate, and when?

    Lock, R.

    1993-07-01

    The goal of this paper is to explore how compliance with the Clean Air Act Amendments of 1990 (CAAA), especially Title IV and emission trading under it, will affect the current relationship between state and federal regulation. It is difficult, with the limited experience we have had under Title IV, to be definitive about or to be a very strong advocate of too many policy positions. What may be most helpful at this point is to identify where the difficult issues in state/federal relations might arise; and then to explore ways in which tensions might be either avoided or resolved. One anticipated conclusion is that a traditional regulatory mindset could be very destructive if applied to this new area of oversight without due sensitivity to what Congress is trying to achieve in Title IV. That concern pervaded the early legislative debates; and it persists today. Title IV presents some unique challenges to state regulators and will require some creative solutions and fresh thinking if the goals of Congress are to be realized and the full benefits that allowance trading can offer are to be reaped by electricity consumers. In the ultimate analysis, Title IV amounts to a massive internalization of the external costs imposed on society by acid rain deposition. (This places in serious question the notion of additional externality {open_quotes}adders{close_quotes} for sulfur dioxide (SO{sub 2}) and nitrous oxide (NO{sub x}) at the state level for utility supply planning purposes.) The whole point of Title IV is to give those directly charged with compliance, namely power producers, the maximum flexibility to pursue least-cost compliance solutions. Perhaps the biggest single factor in how well they do this will be how state regulators respond to their compliance and allowance trading initiatives.

This article addresses the issue of what constitutes an adequate portfolio of drugs for a drug development firm and how it might be managed successfully. The paper investigates decision-making in the industry and specifically in the development of oncology drugs from various perspectives: the need for decisions, their timing, decision-making at the project level, the optimal portfolio, tools for portfolio analysis, the evaluation of patents, and finally the importance of the drug portfolio. Drug development decisions as important organizational elements should get more emphasis, and decisions in drug portfolio using modern decision-making methods should be used more widely than what currently happens. Structured, informed decisions would help avoiding late terminations of drugs in Phase III development. An improved research and development pipeline and drug portfolio management are the major elements in the general strategy targeting success. PMID:25364229

    Elsewhere in this issue of the Federal Register, the IRS is issuing temporary regulations relating to minimum hospital length-of-stay requirements imposed on group health plans with respect to mothers and newborns. The hospital length-of-stay requirements were added to the Internal Revenue Code by section 1531 of the Taxpayer Relief Act of 1997. The IRS is issuing the temporary regulations at the same time that the Pension and Welfare Benefits Administration of the U.S. Department of Labor and the Health Care Financing Administration of the U.S. Department of Health and Human Services are issuing substantially similar interim final regulations relating to hospital length-of-stay requirements added by the Newborns' and Mothers' Health Protection Act of 1996 to the Employee Retirement Income Security Act of 1974 and the Public Health Service Act. The temporary regulations provide guidance to employers and group health plans relating to the new hospital length-of-stay requirements. The text of those temporary regulations also serves as the text of these proposed regulations.

    IL-17 is a pro-inflammatory cytokine implicated in the pathogenesis of autoimmune diseases including psoriasis. ACT1 is an essential adaptor molecule in the IL-17 signaling pathway. A missense single nucleotide polymorphism (rs33980500; SNP-D10N) that resulted in the substitution of an asparagine for an aspartic acid at position 10 of ACT1 (ACT1-D10N) is associated with psoriasis susceptibility. Due to alternative splicing in humans, SNP-D10N encodes two mutated ACT1 proteins, ACT1-D10N and ACT1-D19N. Though both ACT1 isoforms are Hsp90 ‘client’ proteins, the nine additional amino acids in ACT1-D19N provide an additional Hsp90 binding site that is absent in ACT1-D10N. Therefore, while ACT1-D10N is a dead protein that is unable to transduce IL-17 signals for gene expression, ACT1-D19N is fully responsive to IL-17. Intriguingly, the two ACT1 isoforms are differentially expressed in ACT1D10N/D10N fibroblasts and T cells. Fibroblasts express both isoforms equally, enabling ACT1-D19N to compensate for the loss of ACT1-D10N function. ACT1D10N/D10N T cells, however, express predominantly ACT1-D10N. Lacking this compensatory mechanism, ACT1D10N/D10N T cells behave like ACT1-deficient T cells, exhibiting a dysregulated and hyperactive Th17 phenotype with overproduction of IL-22 and IL-17. The hyperactive Th17 response combined with fully responsive fibroblasts likely synergized to contribute to psoriasis susceptibility in SNP-D10N patients. PMID:25024377

The nonattainment, toxics, and permit provisions of the amended act will be three areas of particular concern to the fertilizer industry. Implementation of the new regulatory requirements of this legislation promises to be a long and onerous process for all concerned. However, it appears that state and local regulations may have a much more profound impact on the fertilizer industry than the new Clean Air Act.

    Lack of guidance for interpreting the definitions of endangered and threatened in the U.S. Endangered Species Act (ESA) has resulted in case-by-case decision making leaving the process vulnerable to being considered arbitrary or capricious. Adopting quantitative decision rules would remedy this but requires the agency to specify the relative urgency concerning extinction events over time, cutoff risk values corresponding to different levels of protection, and the importance given to different types of listing errors. We tested the performance of 3 sets of decision rules that use alternative functions for weighting the relative urgency of future extinction events: a threshold rule set, which uses a decision rule of x% probability of extinction over y years; a concave rule set, where the relative importance of future extinction events declines exponentially over time; and a shoulder rule set that uses a sigmoid shape function, where relative importance declines slowly at first and then more rapidly. We obtained decision cutoffs by interviewing several biologists and then emulated the listing process with simulations that covered a range of extinction risks typical of ESA listing decisions. We evaluated performance of the decision rules under different data quantities and qualities on the basis of the relative importance of misclassification errors. Although there was little difference between the performance of alternative decision rules for correct listings, the distribution of misclassifications differed depending on the function used. Misclassifications for the threshold and concave listing criteria resulted in more overprotection errors, particularly as uncertainty increased, whereas errors for the shoulder listing criteria were more symmetrical. We developed and tested the framework for quantitative decision rules for listing species under the U.S. ESA. If policy values can be agreed on, use of this framework would improve the implementation of the ESA by

  5. Positive Selection within a Diatom Species Acts on Putative Protein Interactions and Transcriptional Regulation

    2013-01-01

    Diatoms are the most species-rich group of microalgae, and their contribution to marine primary production is important on a global scale. Diatoms can form dense blooms through rapid asexual reproduction; mutations acquired and propagated during blooms likely provide the genetic, and thus phenotypic, variability upon which natural selection may act. Positive selection was tested using genome and transcriptome-wide pair-wise comparisons of homologs in three genera of diatoms (Pseudo-nitzschia, Ditylum, and Thalassiosira) that represent decreasing phylogenetic distances. The signal of positive selection was greatest between two strains of Thalassiosira pseudonana. Further testing among seven strains of T. pseudonana yielded 809 candidate genes of positive selection, which are 7% of the protein-coding genes. Orphan genes and genes encoding protein-binding domains and transcriptional regulators were enriched within the set of positively selected genes relative to the genome as a whole. Positively selected genes were linked to the potential selective pressures of nutrient limitation and sea surface temperature based on analysis of gene expression profiles and identification of positively selected genes in subsets of strains from locations with similar environmental conditions. The identification of positively selected genes presents an opportunity to test new hypotheses in natural populations and the laboratory that integrate selected genotypes in T. pseudonana with their associated phenotypes and selective forces.

  7. Impact of Clean Air Act Regulations on Nitrogen Fate and Transport in the Neuse River Basin

    2012-12-01

    This study investigated impacts of Clean Air Act Amendment (CAAA) NOx emissions regulations on the fate and transport of nitrogen for two watersheds in the Neuse River Basin, North Carolina, USA from 1990 to 2020. The Soil and Water Assessment Tool (SWAT) and the Community Multi-scale Air Quality (CMAQ) modeling system were used. CMAQ simulated atmospheric chemical transport and nitrogen deposition. This data was entered into SWAT which simulated watershed hydrology and water quality. Two cases were investigated: one that incorporates CAAA regulatory emissions controls in CMAQ simulation (with) and a second case that does not (without). SWAT model results forecasted a 70% decrease in inorganic nitrogen discharge from the Little River watershed and a 50% decrease for the Nahunta watershed by 2020 under the emission control (with) scenario. Denitrification and plant nitrogen uptake played important roles in nitrogen discharge from each watershed. The nitrogen discharge response time following a change in atmospheric nitrogen deposition was 4 years for the Nahunta watershed and 2 years for the Little River watershed. The longer response time for Nahunta is primarily due to a higher percentage of soybean land cover (22.5% [Nahunta]; 1.6% [Little River]). Agricultural land covers had varied nitrogen response times to changes in atmospheric deposition, particularly for soybean, hay and corn. The studied watersheds retained >80% of all nitrogen delivered by agriculture fertilization, biological fixation and atmospheric deposition.

  8. Regulated cell-to-cell variation in a cell-fate decision system.

    2005-09-29

    Here we studied the quantitative behaviour and cell-to-cell variability of a prototypical eukaryotic cell-fate decision system, the mating pheromone response pathway in yeast. We dissected and measured sources of variation in system output, analysing thousands of individual, genetically identical cells. Only a small proportion of total cell-to-cell variation is caused by random fluctuations in gene transcription and translation during the response ('expression noise'). Instead, variation is dominated by differences in the capacity of individual cells to transmit signals through the pathway ('pathway capacity') and to express proteins from genes ('expression capacity'). Cells with high expression capacity express proteins at a higher rate and increase in volume more rapidly. Our results identify two mechanisms that regulate cell-to-cell variation in pathway capacity. First, the MAP kinase Fus3 suppresses variation at high pheromone levels, while the MAP kinase Kss1 enhances variation at low pheromone levels. Second, pathway capacity and expression capacity are negatively correlated, suggesting a compensatory mechanism that allows cells to respond more precisely to pheromone in the presence of a large variation in expression capacity.

  13. Toward a multi-objective decision support framework to support regulations of unconventional oil and gas development

    NASA Astrophysics Data System (ADS)

    Alongi, M.; Howard, C.; Kasprzyk, J. R.; Ryan, J. N.

    2015-12-01

    Unconventional oil and gas development (UOGD) using hydraulic fracturing and horizontal drilling has recently fostered an unprecedented acceleration in energy development. Regulations seek to protect environmental quality of areas surrounding UOGD, while maintaining economic benefits. One such regulation is a setback distance, which dictates the minimum proximity between an oil and gas well and an object such as a residential or commercial building, property line, or water source. In general, most setback regulations have been strongly politically motivated without a clear scientific basis for understanding the relationship between the setback distance and various performance outcomes. This presentation discusses a new decision support framework for setback regulations, as part of a large NSF-funded sustainability research network (SRN) on UOGD. The goal of the decision support framework is to integrate a wide array of scientific information from the SRN into a coherent framework that can help inform policy regarding UOGD. The decision support framework employs multiobjective evolutionary algorithm (MOEA) optimization coupled with simulation models of air quality and other performance-based outcomes on UOGD. The result of the MOEA optimization runs are quantitative tradeoff curves among different objectives. For example, one such curve could demonstrate air pollution concentrations versus estimates of energy development profits, for different levels of setback distance. Our results will also inform policy-relevant discussions surrounding UOGD such as comparing single- and multi-well pads, as well as regulations on the density of well development over a spatial area.

  6. Application of TALEs, CRISPR/Cas and sRNAs as trans-acting regulators in prokaryotes.

    PubMed

    Copeland, Matthew F; Politz, Mark C; Pfleger, Brian F

    2014-10-01

    The last several years have witnessed an explosion in the understanding and use of novel, versatile trans-acting elements. TALEs, CRISPR/Cas, and sRNAs can be easily fashioned to bind any specific sequence of DNA (TALEs, CRISPR/Cas) or RNA (sRNAs) because of the simple rules governing their interactions with nucleic acids. This unique property enables these tools to repress the expression of genes at the transcriptional or post-transcriptional levels, respectively, without prior manipulation of cis-acting and/or chromosomal target DNA sequences. These tools are now being harnessed by synthetic biologists, particularly those in the eukaryotic community, for genome-wide regulation, editing, or epigenetic studies. Here we discuss the exciting opportunities for using TALEs, CRISPR/Cas, and sRNAs as synthetic trans-acting regulators in prokaryotes.

    2000-11-21

    This document contains a final regulation revising the minimum requirements for benefit claims procedures of employee benefit plans covered by Title I of the Employee Retirement Income Security Act of 1974 (ERISA or the Act). The regulation establishes new standards for the processing of claims under group health plans and plans providing disability benefits and further clarifies existing standards for all other employee benefit plans. The new standards are intended to ensure more timely benefit determinations, to improve access to information on which a benefit determination is made, and to assure that participants and beneficiaries will be afforded a full and fair review of denied claims. When effective, the regulation will affect participants and beneficiaries of employee benefit plans, employers who sponsor employee benefit plans, plan fiduciaries, and others who assist in the provision of plan benefits, such as third-party benefits administrators and health service providers or health maintenance organizations that provide benefits to participants and beneficiaries of employee benefit plans.

    2015-07-01

    A key challenge in the field of T-cell immunotherapy for cancer is creating a suitable platform for promoting differentiation of effector cells while at the same time enabling self-renewal needed for long-term memory. Although transfer of less differentiated memory T cells increases efficacy through greater expansion and persistence in vivo, the capacity of such cells to sustain effector functions within immunosuppressive tumor microenvironments may still be limiting. We have therefore directly compared the impact of effector versus memory differentiation of therapeutic T cells in tumor-bearing mice by introducing molecular switches that regulate cell fate decisions via mTOR. Ectopic expression of RAS homolog enriched in brain (RHEB) increased mTORC1 signaling, promoted a switch to aerobic glycolysis, and increased expansion of effector T cells. By rapidly infiltrating tumors, RHEB-transduced T cells significantly reduced the emergence of immunoedited escape variants. In contrast, expression of proline-rich Akt substrate of 40 kDa (PRAS40) inhibited mTORC1, promoted quiescence, and blocked tumor infiltration. Fate mapping studies following transient expression of PRAS40 demonstrated that mTORC1(low) T cells made no contribution to initial tumor control but instead survived to become memory cells proficient in generating recall immunity. Our data support the design of translational strategies for generating heterogeneous T-cell immunity against cancer, with the appropriate balance between promoting effector differentiation and self-renewal. Unlike pharmacologic inhibitors, the genetic approach described here allows for upregulation as well as inhibition of the mTORC1 pathway and is highly selective for the therapeutic T cells without affecting systemic mTORC1 functions.

  10. Arid3a is essential to execution of the first cell fate decision via direct embryonic and extraembryonic transcriptional regulation

    2014-01-01

    Despite their origin from the inner cell mass, embryonic stem (ES) cells undergo differentiation to the trophectoderm (TE) lineage by repression of the ES cell master regulator Oct4 or activation of the TE master regulator Caudal-type homeobox 2 (Cdx2). In contrast to the in-depth studies of ES cell self-renewal and pluripotency, few TE-specific regulators have been identified, thereby limiting our understanding of mechanisms underlying the first cell fate decision. Here we show that up-regulation and nuclear entry of AT-rich interactive domain 3a (Arid3a) drives TE-like transcriptional programs in ES cells, maintains trophoblast stem (TS) cell self-renewal, and promotes further trophoblastic differentiation both upstream and independent of Cdx2. Accordingly, Arid3a−/− mouse post-implantation placental development is severely impaired, resulting in early embryonic death. We provide evidence that Arid3a directly activates TE-specific and trophoblast lineage-specific genes while directly repressing pluripotency genes via differential regulation of epigenetic acetylation or deacetylation. Our results identify Arid3a as a critical regulator of TE and placental development through execution of the commitment and differentiation phases of the first cell fate decision. PMID:25319825

    2014-12-01

    Sophisticated, intentional decision-making is a hallmark of mature, self-aware behaviour. Although neural, psychological, interpersonal, and socioeconomic elements that contribute to such adaptive, foresighted behaviour mature and/or change throughout the life-span, here we concentrate on relevant maturational processes that take place during adolescence, a period of disproportionate developmental opportunity and risk. A brief, eclectic overview is presented of recent evidence, new challenges, and current thinking on the fundamental mechanisms that mature throughout adolescence to support adaptive, self-controlled decision-making. This is followed by a proposal for the putative contribution of frontostriatal mechanisms to the moment-to-moment assembly of evaluative heuristics that mediate increased decision-making sophistication, promoting the maturation of self-regulated behaviour through adolescence and young adulthood.

    We analyze factors determining women’s decisions to participate in the labor market and provide elderly care and nonfinancial support to their (grand)children. We use data from the Mexican Health and Aging Study, a survey of people aged 50 and over, applying a three-equation, reduced-form SUR model. Results suggest that care needs are the driving force behind caregiving activities. Traditional roles also appear to be relevant in the labor force participation decision: women with a closer labor market connection when they were young are more likely to work. Simulations of demographic changes illustrate potential effects for future caregiving and participation rates. PMID:26924883

    The glutamine synthetase (GS) gene family in pea (Pisum sativum) consists of four nuclear genes encoding distinct isoenzymes. Molecular studies have show that the GS2 gene encoding chloroplast-localized GS is expected in specific cell types and is regulated by diverse factors such as light and photorespiration. Here, we present the nucleotide sequence of the pea GS2 gene promoter. To identify the elements involved in regulation of GS2 expression, GS2 promoter-deletion analyses were performed using GS2-GUS fusions in tobacco (Nicotiana tabacum). This analysis revealed that the GS2 transit peptide is not required for mesophyll cell-specific expression of beta-glucuronidase (GUS). GUS activity was induced 2- to 4-fold in light-grown versus etiolated T1 seedlings. However, high levels of GUS activity were observed in etiolated seedlings. This observation demonstrated that regulation of expression of GS2, a nonphotosynthetic light-regulated gene, involves additional factors. A 323-bp GS2 promoter sequence is sufficient to confer light regulation to the GUS reporter gene in leaves of mature transgenic tobacco. Light-regulated expression of this pea gene promoter is observed in both tobacco and Arabidopsis, suggesting that the regulatory elements are conserved. Gel-shift analysis detected DNA-protein complexes formed with potential transcription elements within this short, light-responsive GS2 promoter fragment. PMID:7630938

    Recent developments in computer software have raised the possibility that federal regulators may claim to control medical computer software as a “device” under the Food, Drug and Cosmetic Act. The purpose of this paper is to analyze the FDCA to determine whether computer software is included in the statutory scheme, examine constitutional arguments relating to computer software, and discuss regulatory principles that should be taken into account when deciding appropriate regulation. This paper is limited to computer program output used by humans in deciding appropriate medical therapy for a patient.

    1996-07-01

    Title III of the 1990 Clean Air Act Amendments (CAAA) addresses the control of hazardous air pollutants (HAPs) from major sources of air pollution in the US. In the CAAA, Congress defined 189 compounds as hazardous air pollutants in need of additional control by the Environmental Protection Agency (EPA). Congress directed EPA to identify the major source categories which emit HAPs and to prepare regulations that would reduce and control future HAP emissions. This paper outlines the activities undertaken by EPA to regulate HAP emissions from Portland cement plants and the program developed by the Portland cement manufacturing industry to cope with Title III.

  8. DAY NEUTRAL FLOWERING does not act through GIGANTEA and FKF1 to regulate CONSTANS expression and flowering time.

    2010-09-01

    The regulation of CONSTANS (CO) gene expression and protein levels is the critical factor in determining a plant's response to photoperiod, flowering is induced when high levels of CO protein are present in the light. The regulation of CO transcription is mediated in part by GIGANTEA (GI), FKF1 and the CYCLING DOF FACTORS (CDFs) and factors affecting the levels of these proteins will also affect CO expression. The DAY NEUTRAL FLOWERING (DNF) protein is an E3 ligase involved in repressing CO expression in the early part of the day. In this article we present evidence to support the argument that DNF is not acting through the GI/FKF1/CDF regulatory mechanism to repress CO expression, but that it acts on another transcriptional activator of CO.

    2008-11-21

    TetR-like transcriptional repressors interact with small-molecule ligands to control many facets of prokaryotic biology, including clinical antibiotic resistance. ActR is a TetR-like protein encoded in the biosynthetic gene cluster for the antibiotic actinorhodin and controls the expression of two actinorhodin exporters. We showed previously that actinorhodin and its precursor 4-dihydro-9-hydroxy-1-methyl-10-oxo-3-H-naphtho-[2,3-c]-pyran-3-(S)-acetic acid can bind ActR and prevent its interaction with DNA. Here, we compare ActR's interaction with naturally occurring and synthetic molecules to show that pathway intermediates bind to ActR 5- to 10-fold more tightly than actinorhodin itself, consistent with our suggestion that they are the biologically relevant triggers for actinorhodin export. We also find that the ligand-binding cavity of this protein can accommodate a surprisingly large diversity of ligands, many of which can release ActR from DNA in vitro and in vivo. These data suggest that the actR locus could be activated by, and perhaps adapted to confer resistance to other antibiotics.

    1992-09-01

    In a further analysis of gene regulation of figwort mosaic virus (FMV), a caulimovirus, we studied transient gene expression with modified viral genomes in Nicotiana edwardsonii cell suspension protoplasts. The results demonstrated that the presence of the promoter for the full-length RNA interferes with expression from the separate downstream promoter for gene VI. In addition, expression of gene VI was inhibited by cis-acting sequences within gene VI itself. Both inhibitory effects could be partially relieved by coelectroporation with a plasmid that produces gene VI protein, demonstrating that expression of gene VI is transactivated by its own product. Subsequent expression studies with partially redundant FMV plasmids containing a reporter gene in frame with gene IV showed that efficient transactivation of CAT expression relies on a cis-acting element inside the downstream gene VI. Insertions of a transcriptional terminator upstream of the cis-acting element for premature termination of transcription showed that the cis-acting region is not a DNA element but is active only as a feature of the RNA transcript. We conclude that the cis-acting element, together with the transacting gene VI product, enhances expression of all major genes, including gene VI, from the polycistronic mRNA and the separate mRNA for gene VI.

    2015-08-01

    The Dietary Supplement Health and Education Act (DSHEA) of 1994 defines the FDA's statutory authority to regulate dietary supplement products in the United States. The dietary supplement industry has rapidly expanded since 1994, presenting an obvious need for "DSHEA 2.0." Current regulations surrounding dietary supplements have been increasingly and reasonably scrutinized, given their widespread use by over one-half of the US population as well as highly publicized safety concerns over the past 20 y. As the market continues to expand and evolve, so too must the laws that protect consumers from potential harm and misleading communication.

  19. Fnr (EtrA) acts as a fine-tuning regulator of anaerobic metabolism in Shewanella oneidensis MR-1

    EtrA in Shewanella oneidensis MR-1, a model organism for study of adaptation to varied redox niches, shares 73.6% and 50.8% amino acid sequence identity with the oxygen-sensing regulators Fnr in E. coli and Anr in Pseudomonas aeruginosa, respectively; however, its regulatory role of anaerobic metabolism in Shewanella spp. is not well understood. The expression of the nap genes, nrfA, cymA and hcp was significantly reduced in etrA deletion mutant EtrA7-1; however, limited anaerobic growth and nitrate reduction occurred, suggesting that multiple regulators control nitrate reduction in this strain. Dimethyl sulfoxide (DMSO) and fumarate reductase gene expression was down regulated at least 2-fold and the EtrA7-1 mutant grew poorly with fumarate and dimethyl sulfoxide (DMSO), suggesting both respiratory pathways are under EtrA control. Transcript analysis further suggested a role of EtrA in prophage activation and down regulation of genes implicated in aerobic metabolism. In contrast to previous studies that attributed a minor regulatory role to EtrA in Shewanella spp., this study demonstrates that EtrA acts as a global transcriptional regulator and confers physiological advantages to strain MR-1 under certain growth conditions. In conjunction with other regulators, EtrA fine-tunes the expression of genes involved in anaerobic metabolism in S. oneidensis strain MR-1.

  5. Trans-acting factors regulate the expression of CD44 splice variants.

    PubMed Central

    Konig, H; Moll, J; Ponta, H; Herrlich, P

    1996-01-01

    Variant isoforms of the cell surface glycoprotein CD44 (CD44v) are expressed during development, in selected adult tissues and in certain metastatic tumor cells. CD44v differ from the standard isoform (CD44s) by up to ten additional exon sequences included by alternative splicing. By cell fusion experiments, we have obtained evidence for the existence of cell-type specific trans-acting factors recruiting CD44 variant exon sequences. Stable cell hybrids of CD44s and CD44v expressing cells indicated a dominant mechanism for variant-exon inclusion. In transient interspecies heterokaryons of human keratinocytes and rat fibroblasts, the ability of the keratinocytes to include all variant exon sequences in CD44 was conferred completely on the rat fibroblast nucleus. Fusions of cells with complex CD44 splice patterns do not permit interpretation of splice control by the relative abundance of a single trans-acting factor, but rather by (a) positively acting factor(s) recruiting variant exon sequences in the 3' to 5' direction and additional factors selecting individual exons. Since the pancreatic carcinoma cell line BSp73ASML (in contrast to the cervix carcinoma cell lines SiHa and ME180) could not transfer its specific splice pattern in cell fusions, we conclude that in some tumors, splicing is also controlled by mutation of cis-acting recognition sites.

    Many environmental regulations encourage the use of 'clean' inputs. When the suppliers of such an input have market power, environmental regulation will affect not only the quantity of the input used but also its price. We investigate the effect of the Title IV emissions trading program for sulfur dioxide on the market for low-sulfur coal. We find that the two railroads transporting coal were able to price discriminate on the basis of environmental regulation and geographic location. Delivered prices rose for plants in the trading program relative to other plants, and by more at plants near a low-sulfur coal source.

  12. Neuronal correlates of decisions to speak and act: Spontaneous emergence and dynamic topographies in a computational model of frontal and temporal areas.

    PubMed

    Garagnani, Max; Pulvermüller, Friedemann

    2013-10-01

    The neural mechanisms underlying the spontaneous, stimulus-independent emergence of intentions and decisions to act are poorly understood. Using a neurobiologically realistic model of frontal and temporal areas of the brain, we simulated the learning of perception-action circuits for speech and hand-related actions and subsequently observed their spontaneous behaviour. Noise-driven accumulation of reverberant activity in these circuits leads to their spontaneous ignition and partial-to-full activation, which we interpret, respectively, as model correlates of action intention emergence and action decision-and-execution. Importantly, activity emerged first in higher-association prefrontal and temporal cortices, subsequently spreading to secondary and finally primary sensorimotor model-areas, hence reproducing the dynamics of cortical correlates of voluntary action revealed by readiness-potential and verb-generation experiments. This model for the first time explains the cortical origins and topography of endogenous action decisions, and the natural emergence of functional specialisation in the cortex, as mechanistic consequences of neurobiological principles, anatomical structure and sensorimotor experience.

  13. Behavioral contagion during learning about another agent’s risk-preferences acts on the neural representation of decision-risk

    2016-01-01

    Our attitude toward risk plays a crucial role in influencing our everyday decision-making. Despite its importance, little is known about how human risk-preference can be modulated by observing risky behavior in other agents at either the behavioral or the neural level. Using fMRI combined with computational modeling of behavioral data, we show that human risk-preference can be systematically altered by the act of observing and learning from others’ risk-related decisions. The contagion is driven specifically by brain regions involved in the assessment of risk: the behavioral shift is implemented via a neural representation of risk in the caudate nucleus, whereas the representations of other decision-related variables such as expected value are not affected. Furthermore, we uncover neural computations underlying learning about others’ risk-preferences and describe how these signals interact with the neural representation of risk in the caudate. Updating of the belief about others’ preferences is associated with neural activity in the dorsolateral prefrontal cortex (dlPFC). Functional coupling between the dlPFC and the caudate correlates with the degree of susceptibility to the contagion effect, suggesting that a frontal–subcortical loop, the so-called dorsolateral prefrontal–striatal circuit, underlies the modulation of risk-preference. Taken together, these findings provide a mechanistic account for how observation of others’ risky behavior can modulate an individual’s own risk-preference. PMID:27001826

  16. Ethylene acts as a negative regulator of glucose induced lateral root emergence in Arabidopsis.

    Singh, Manjul; Gupta, Aditi; Laxmi, Ashverya

    2015-01-01

    Plants, being sessile organisms, are more exposed to the hazards of constantly changing environmental conditions globally. During the lifetime of a plant, the root system encounters various challenges such as obstacles, pathogens, high salinity, water logging, nutrient scarcity etc. The developmental plasticity of the root system provides brilliant adaptability to plants to counter the changes exerted by both external as well as internal cues and achieve an optimized growth status. Phytohormones are one of the major intrinsic factors regulating all aspects of plant growth and development both independently as well as through complex signal integrations at multiple levels. We have previously shown that glucose (Glc) and brassinosteroid (BR) signalings interact extensively to regulate lateral root (LR) development in Arabidopsis. (1) Auxin efflux as well as influx and downstream signaling components are also involved in Glc-BR regulation of LR emergence. Here, we provide evidence for involvement of ethylene signaling machinery downstream to Glc and BR in regulation of LR emergence. PMID:26236960

    UVB radiation causes cyclobutane pyrimidine dimers (CPDs) to form on the DNA of living organisms. This study found that overexpression of the silicon absorbance gene Lsi1 reduced the accumulation of CPDs in rice, which profited from the reactivation by photolyase. The transcript abundance of deoxyribodipyrimidine photolyase (Os10g0167600) was generally correlated with the silicon content of the rice, and the up-regulation of Os10g0167600 was found to be highest in the UVB-treated Lsi1-overexpressed (Lsi1-OX) rice. A trans-acting factor, methyl-CpG binding domain protein (OsMeCP), was found to interact with the cis-element of Os10g0167600. The nucleic location of OsMeCP effectively enabled the transcriptional regulation. Compared with the WT, the level of OsMeCP was lower in the Lsi1-OX rice but higher in the Lsi1-RNAi line. Rice cultured in a high silicate-concentration solution also exhibited less OsMeCP abundance. Overexpression of OsMeCP led to lower Os10g0167600 transcript levels and a higher CPD content than in the WT, but the reverse was true in the OsMeCP-RNAi line. These findings indicate that OsMeCP acts as a negative regulator of silicon, and can mediate the repression of the transcription from Os10g0167600, which inhibits the photoreactivation of the photolyase involved in the repair of CPDs.

  18. Liability for managed care decisions: the Employee Retirement Income Security Act (ERISA) and the uneven playing field.

    PubMed

    As managed care organizations expand their programs of quality assurance and physician evaluation, more medical malpractice lawsuits may be brought against managed care organizations on the ground that, like hospitals, they are legally responsible for negligent corporate acts that injure patients. However, the federal Employee Retirement Income Security Act (ERISA) shields managed care organizations from liability when they are part of an employee group health plan governed by ERISA. Unlike patients with other types of insurance, patients in ERISA health plans do not have a malpractice remedy for a managed care organization's negligence. A few federal appeals courts recently recognized that ERISA plans can be vicariously liable for their physicians' medical malpractice, but only if the physician is the plan's employee or agent. Yet ERISA still prohibits negligence claims against ERISA health plans for injuries resulting from denial of plan benefits, failure to use qualified physicians, utilization review, or improper plan administration. Current managed care operations do not neatly distinguish between administering benefits and controlling quality of care. Neither should the law. ERISA should be amended to provide employees with the same remedies that patients in non-ERISA plans enjoy.

  19. The transcription factor TFEB acts as a molecular switch that regulates exogenous antigen-presentation pathways.

    Dendritic cells (DCs) can initiate immune responses by presenting exogenous antigens to T cells via both major histocompatibility complex (MHC) class I pathways and MHC class II pathways. Lysosomal activity has an important role in modulating the balance between these two pathways. The transcription factor TFEB regulates lysosomal function by inducing lysosomal activation. Here we report that TFEB expression inhibited the presentation of exogenous antigen by MHC class I while enhancing presentation via MHC class II. TFEB promoted phagosomal acidification and protein degradation. Furthermore, we found that the activation of TFEB was regulated during DC maturation and that phagosomal acidification was impaired in DCs in which the gene encoding TFEB was silenced. Our data indicate that TFEB is a key participant in the differential regulation of the presentation of exogenous antigens by DCs.

  20. Nitric Oxide Acts as a Positive Regulator to Induce Metamorphosis of the Ascidian Herdmania momus

    2013-01-01

    Marine invertebrates commonly have a biphasic life cycle in which the metamorphic transition from a pelagic larva to a benthic post-larva is mediated by the nitric oxide signalling pathway. Nitric oxide (NO) is synthesised by nitric oxide synthase (NOS), which is a client protein of the molecular chaperon heat shock protein 90 (HSP90). It is notable, then, that both NO and HSP90 have been implicated in regulating metamorphosis in marine invertebrates as diverse as urochordates, echinoderms, molluscs, annelids, and crustaceans. Specifically, the suppression of NOS activity by the application of either NOS- or HSP90-inhibiting pharmacological agents has been shown consistently to induce the initiation of metamorphosis, leading to the hypothesis that a negative regulatory role of NO is widely conserved in biphasic life cycles. Further, the induction of metamorphosis by heat-shock has been demonstrated for multiple species. Here, we investigate the regulatory role of NO in induction of metamorphosis of the solitary tropical ascidian, Herdmania momus. By coupling pharmacological treatments with analysis of HmNOS and HmHSP90 gene expression, we present compelling evidence of a positive regulatory role for NO in metamorphosis of this species, in contrast to all existing ascidian data that supports the hypothesis of NO as a conserved negative regulator of metamorphosis. The exposure of competent H. momus larvae to a NOS inhibitor or an NO donor results in an up-regulation of NOS and HSP90 genes. Heat shock of competent larvae induces metamorphosis in a temperature dependent manner, up to a thermal tolerance that approaches 35°C. Both larval/post-larval survival and the appearance of abnormal morphologies in H. momus post-larvae reflect the magnitude of up-regulation of the HSP90 gene in response to heat-shock. The demonstrated role of NO as a positive metamorphic regulator in H. momus suggests the existence of inter-specific adaptations of NO regulation in ascidian

    This report reviews and compares several studies of the effects on employment of regulating wastes from oil and natural gas exploration and extraction under the Resource Conservation and Recovery Act (RCRA). The waste management scenarios on which most of the studies were based were developed by the U.S. Environmental Protection Agency. The analyses show that as many as 500,000-700,000 jobs may be lost in the first year if RCRA Subtitle C rules are applied to drilling fluids and produced waters. As a results, unemployment in major oil-producing states could rise by as much as six percentage points. 13 refs., 4 tabs.

    In the last few decades, awareness of environmental issues has increased significantly. Little has changed, however, in human activities contributing to environmental damage. Why is it so difficult for us to change our behavior in a domain that is clearly so important to the future of humanity? Here we propose and test the possibility that self-signaling, the way we view ourselves based on our past behaviors, is one of the factors contributing to the difficulty of taking environmental action. In three experiments, we show that previous self-interested thoughts or behaviors serve as important signals that hinder the likelihood of acting in line with an individual’s reported concern for the environment. This study not only helps explain the gap between environmental awareness and action, but also suggests alternative strategies for policymakers and environmental agencies to promote proenvironmental behavior.

  10. GIGANTEA acts in blue light signaling and has biochemically separable roles in circadian clock and flowering time regulation.

    2007-01-01

    Circadian clocks are widespread in nature. In higher plants, they confer a selective advantage, providing information regarding not only time of day but also time of year. Forward genetic screens in Arabidopsis (Arabidopsis thaliana) have led to the identification of many clock components, but the functions of most of these genes remain obscure. To identify both new constituents of the circadian clock and new alleles of known clock-associated genes, we performed a mutant screen. Using a clock-regulated luciferase reporter, we isolated new alleles of ZEITLUPE, LATE ELONGATED HYPOCOTYL, and GIGANTEA (GI). GI has previously been reported to function in red light signaling, central clock function, and flowering time regulation. Characterization of this and other GI alleles has helped us to further define GI function in the circadian system. We found that GI acts in photomorphogenic and circadian blue light signaling pathways and is differentially required for clock function in constant red versus blue light. Gene expression and epistasis analyses show that TIMING OF CHLOROPHYLL A/B BINDING PROTEIN1 (TOC1) expression is not solely dependent upon GI and that GI expression is only indirectly affected by TOC1, suggesting that GI acts both in series with and in parallel to TOC1 within the central circadian oscillator. Finally, we found that the GI-dependent promotion of CONSTANS expression and flowering is intact in a gi mutant with altered circadian regulation. Thus GI function in the regulation of a clock output can be biochemically separated from its role within the circadian clock.

    Synthesis of the endogenous opioid precursor, proenkephalin, is regulated by neurotransmitters and membrane depolarization. These events act through second messenger dependent signal transduction pathways via a short inducible DNA enhancer to regulate transcription of the proenkephalin gene. Two DNA elements located within this enhancer are essential for the transcriptional response to cAMP and phorbol ester. Inactivation of either element by mutation or by alteration of their stereospecific alignment eliminates inducible enhancer activity. The promoter distal element, ENKCRE-1, in the absence of a functional adjacent ENKCRE-2 element, has no inherent capacity to activate transcription. However, in the presence of a functional ENKCRE-2 element, this element synergistically augments cAMP and phorbol ester inducible transcription. The promoter proximal element, ENKCRE-2, is essential for both basal and regulated enhancer function. Four different protein factors found in HeLa cell nuclear extracts bind in vitro to the enhancer region. ENKTF-1, a novel enhancer binding protein, binds to the DNA region encompassing ENKCRE-1. The transcription factors AP-1 and AP-4 bind to overlapping sites spanning ENKCRE-2, and a fourth transcription factor, AP-2, binds to a site immediately downstream of ENKCRE-2. The binding of ENKTF-1 to mutant ENKCRE-1 sequences in vitro correlates with the in vivo inducibility of the mutant elements suggesting that ENKTF-1 acts in combination with factors that recognize the ENKCRE-2 domain to regulate cAMP inducible transcription. Together, the two DNA elements, ENKCRE-1 and ENKCRE-2 and the protein factors with which they interact, play a critical role in the transduction and reception of signals transmitted from cell surface receptors to the proenkephalin nuclear transcription complex.

    During the last century, two key hypotheses have been proposed to explain apical dominance in plants: auxin promotes the production of a second messenger that moves up into buds to repress their outgrowth, and auxin saturation in the stem inhibits auxin transport from buds, thereby inhibiting bud outgrowth. The recent discovery of strigolactone as the novel shoot-branching inhibitor allowed us to test its mode of action in relation to these hypotheses. We found that exogenously applied strigolactone inhibited bud outgrowth in pea (Pisum sativum) even when auxin was depleted after decapitation. We also found that strigolactone application reduced branching in Arabidopsis (Arabidopsis thaliana) auxin response mutants, suggesting that auxin may act through strigolactones to facilitate apical dominance. Moreover, strigolactone application to tiny buds of mutant or decapitated pea plants rapidly stopped outgrowth, in contrast to applying N-1-naphthylphthalamic acid (NPA), an auxin transport inhibitor, which significantly slowed growth only after several days. Whereas strigolactone or NPA applied to growing buds reduced bud length, only NPA blocked auxin transport in the bud. Wild-type and strigolactone biosynthesis mutant pea and Arabidopsis shoots were capable of instantly transporting additional amounts of auxin in excess of endogenous levels, contrary to predictions of auxin transport models. These data suggest that strigolactone does not act primarily by affecting auxin transport from buds. Rather, the primary repressor of bud outgrowth appears to be the auxin-dependent production of strigolactones. PMID:19321710

    MicroRNAs (miRNAs) are extensively involved in diverse biological processes. However, very little is known about the role of miRNAs in mediating the action of thyroid hormones (TH). Appropriate TH levels are known to be critically important for development, differentiation and maintenance of metabolic balance in mammals. We induced transient hypothyroidism in juvenile mice by short-term exposure to methimazole and perchlorate from post natal day (PND) 12 to 15. The expression of miRNAs in the liver was analyzed using Taqman Low Density Arrays (containing up to 600 rodent miRNAs). We found the expression of 40 miRNAs was significantly altered in the livers of hypothyroid mice compared to euthyroid controls. Among the miRNAs, miRs-1, 206, 133a and 133b exhibited a massive increase in expression (50- to 500-fold). The regulation of TH on the expression of miRs-1, 206, 133a and 133b was confirmed in various mouse models including: chronic hypothyroid, short-term hyperthyroid and short-term hypothyroid followed by TH supplementation. TH regulation of these miRNAs was also confirmed in mouse hepatocyte AML 12 cells. The expression of precursors of miRs-1, 206, 133a and 133b were examined in AML 12 cells and shown to decrease after TH treatment, only pre-mir-206 and pre-mir-133b reached statistical significance. To identify the targets of these miRNAs, DNA microarrays were used to examine hepatic mRNA levels in the short-term hypothyroid mouse model relative to controls. We found transcripts from 92 known genes were significantly altered in these hypothyroid mice. Web-based target predication software (TargetScan and Microcosm) identified 14 of these transcripts as targets of miRs-1, 206, 133a and 133b. The vast majority of these mRNA targets were significantly down-regulated in hypothyroid mice, corresponding with the up-regulation of miRs-1, 206, 133a and 133b in hypothyroid mouse liver. To further investigate target genes, miR-206 was over-expressed in AML 12 cells. TH

    2015-01-01

    Summary Superoxide dismutase 1 (Sod1) has been known for nearly half a century for catalysis of superoxide to hydrogen peroxide. Here we report a new Sod1 function in oxidative signaling: in response to elevated endogenous and exogenous reactive oxygen species (ROS), Sod1 rapidly relocates into the nucleus, which is important for maintaining genomic stability. Interestingly, H2O2 is sufficient to promote Sod1 nuclear localization, indicating that it is responding to general ROS rather than Sod1 substrate superoxide. ROS signaling is mediated by Mec1/ATM and its effector Dun1/Cds1 kinase, through Dun1 interaction with Sod1 and regulation of Sod1 by phosphorylation at S60, 99. In the nucleus, Sod1 binds to the promoters and regulates the expression of oxidative resistance and repair genes. Altogether, our study unravels an unorthodox function of Sod1 as a transcription factor and elucidates the regulatory mechanism for its localization. PMID:24647101

    Though evidence is mounting that a major function of sleep is to maintain brain plasticity and consolidate memory, little is known about the molecular pathways by which learning and sleep processes intercept. Anaplastic lymphoma kinase (Alk), the gene encoding a tyrosine receptor kinase whose inadvertent activation is the cause of many cancers, is implicated in synapse formation and cognitive functions. In particular, Alk genetically interacts with Neurofibromatosis 1 (Nf1) to regulate growth and associative learning in flies. We show that Alk mutants have increased sleep. Using a targeted RNAi screen we localized the negative effects of Alk on sleep to the mushroom body, a structure important for both sleep and memory. We also report that mutations in Nf1 produce a sexually dimorphic short sleep phenotype, and suppress the long sleep phenotype of Alk. Thus Alk and Nf1 interact in both learning and sleep regulation, highlighting a common pathway in these two processes. PMID:26536237

    Primitive hematopoiesis occurs in the yolk sac blood islands during vertebrate embryogenesis, where abundant phosphatidylcholines (PC) are available as important nutrients for the developing embryo. However, whether these phospholipids also generate developmental cues to promote hematopoiesis is largely unknown. Here, we show that lysophosphatidic acid (LPA), a signaling molecule derived from PC, regulated hemangioblast formation and primitive hematopoiesis. Pharmacological and genetic blockage of LPA receptor 1 (LPAR1) or autotoxin (ATX), a secretory lysophospholipase that catalyzes LPA production, inhibited hematopoietic differentiation of mouse embryonic stem cells and impaired the formation of hemangioblasts. Mechanistic experiments revealed that the regulatory effect of ATX-LPA signaling was mediated by PI3K/Akt-Smad pathway. Furthermore, during in vivo embryogenesis in zebrafish, LPA functioned as a developmental cue for hemangioblast formation and primitive hematopoiesis. Taken together, we identified LPA as an important nutrient-derived developmental cue for primitive hematopoiesis as well as a novel mechanism of hemangioblast regulation. PMID:24829209

    Signaling pathways and transcription factors are crucial regulators of vertebrate neurogenesis, exerting their function in a spatial and temporal manner. Despite recent advances in our understanding of the molecular regulation of embryonic neurogenesis, little is known regarding how different signaling pathways interact to tightly regulate this process during the development of neuroepithelia. To address this, we have investigated the events lying upstream and downstream of a key neurogenic factor, the Cut-like homeodomain transcription factor-2 (Cux2), during embryonic neurogenesis in chick and mouse. By using the olfactory epithelium as a model for neurogenesis we have analyzed mouse embryos deficient in Cux2, as well as chick embryos exposed to Cux2 silencing (si) RNA or a Cux2 over-expression construct. We provide evidence that enhanced BMP activity increases Cux2 expression and suppresses olfactory neurogenesis in the chick olfactory epithelium. In addition, our results show that up-regulation of Cux2, either BMP-induced or ectopically over-expressed, reduce Delta1 expression and suppress proliferation. Interestingly, the loss of Cux2 activity, using mutant mice or siRNA in chick, also diminishes neurogenesis, Notch activity and cell proliferation in the olfactory epithelium. Our results suggest that controlled low levels of Cux2 activity are necessary for proper Notch signaling, maintenance of the proliferative pool and ongoing neurogenesis in the olfactory epithelium. Thus, we demonstrate a novel conserved mechanism in vertebrates in which levels of Cux2 activity play an important role for ongoing neurogenesis in the olfactory epithelium.

    Calretinin (CALB2) is a diagnostic marker for epithelioid mesothelioma. It is also a prognostic marker since patients with tumors expressing high calretinin levels have better overall survival. Silencing of calretinin decreases viability of epithelioid mesothelioma cells. Our aim was to elucidate mechanisms regulating calretinin expression in mesothelioma. Analysis of calretinin transcript and protein suggested a control at the mRNA level. Treatment with 5-aza-2'-deoxycytidine and analysis of TCGA data indicated that promoter methylation is not likely to be involved. Therefore, we investigated CALB2 promoter by analyzing ~1kb of genomic sequence surrounding the transcription start site (TSS) + 1 using promoter reporter assay. Deletion analysis of CALB2 proximal promoter showed that sequence spanning the -161/+80bp region sustained transcriptional activity. Site-directed analysis identified important cis-regulatory elements within this -161/+80bp CALB2 promoter. EMSA and ChIP assays confirmed binding of NRF-1 and E2F2 to the CALB2 promoter and siRNA knockdown of NRF-1 led to decreased expression of calretinin. Cell synchronization experiment showed that calretinin expression was cell cycle regulated with a peak of expression at G1/S phase. This study provides the first insight in the regulation of CALB2 expression in mesothelioma cells.

    The myocardin-related transcription factors (MRTF-A and MRTF-B) regulate cytoskeletal genes through their partner transcription factor SRF. The MRTFs bind G-actin, and signal-regulated changes in cellular G-actin concentration control their nuclear accumulation. The MRTFs also undergo Rho- and ERK-dependent phosphorylation, but the function of MRTF phosphorylation, and the elements and signals involved in MRTF-A nuclear export are largely unexplored. We show that Rho-dependent MRTF-A phosphorylation reflects relief from an inhibitory function of nuclear actin. We map multiple sites of serum-induced phosphorylation, most of which are S/T-P motifs and show that S/T-P phosphorylation is required for transcriptional activation. ERK-mediated S98 phosphorylation inhibits assembly of G-actin complexes on the MRTF-A regulatory RPEL domain, promoting nuclear import. In contrast, S33 phosphorylation potentiates the activity of an autonomous Crm1-dependent N-terminal NES, which cooperates with five other NES elements to exclude MRTF-A from the nucleus. Phosphorylation thus plays positive and negative roles in the regulation of MRTF-A. DOI: http://dx.doi.org/10.7554/eLife.15460.001 PMID:27304076

Therefore, we investigated CALB2 promoter by analyzing ~1kb of genomic sequence surrounding the transcription start site (TSS) + 1 using promoter reporter assay. Deletion analysis of CALB2 proximal promoter showed that sequence spanning the −161/+80bp region sustained transcriptional activity. Site-directed analysis identified important cis-regulatory elements within this −161/+80bp CALB2 promoter. EMSA and ChIP assays confirmed binding of NRF-1 and E2F2 to the CALB2 promoter and siRNA knockdown of NRF-1 led to decreased expression of calretinin. Cell synchronization experiment showed that calretinin expression was cell cycle regulated with a peak of expression at G1/S phase. This study provides the first insight in the regulation of CALB2 expression in mesothelioma cells. PMID:26848772

  7. An Arabidopsis F-box protein acts as a transcriptional co-factor to regulate floral development.

    2008-04-01

    Plants flower in response to both environmental and endogenous signals. The Arabidopsis LEAFY (LFY) transcription factor is crucial in integrating these signals, and acts in part by activating the expression of multiple floral homeotic genes. LFY-dependent activation of the homeotic APETALA3 (AP3) gene requires the activity of UNUSUAL FLORAL ORGANS (UFO), an F-box component of an SCF ubiquitin ligase, yet how this regulation is effected has remained unclear. Here, we show that UFO physically interacts with LFY both in vitro and in vivo, and this interaction is necessary to recruit UFO to the AP3 promoter. Furthermore, a transcriptional repressor domain fused to UFO reduces endogenous LFY activity in plants, supporting the idea that UFO acts as part of a transcriptional complex at the AP3 promoter. Moreover, chemical or genetic disruption of proteasome activity compromises LFY-dependent AP3 activation, indicating that protein degradation is required to promote LFY activity. These results define an unexpected role for an F-box protein in functioning as a DNA-associated transcriptional co-factor in regulating floral homeotic gene expression. These results suggest a novel mechanism for promoting flower development via protein degradation and concomitant activation of the LFY transcription factor. This mechanism may be widely conserved, as homologs of UFO and LFY have been identified in a wide array of plant species. PMID:18287201

  8. The exosome and trans-acting small interfering RNAs regulate cuticular wax biosynthesis during Arabidopsis inflorescence stem development.

    The primary aerial surfaces of land plants are covered with a cuticle, a protective layer composed of the cutin polyester matrix and cuticular waxes. Previously, we discovered a unique mechanism of regulating cuticular wax biosynthesis during Arabidopsis (Arabidopsis thaliana) stem elongation that involves ECERIFERUM7 (CER7), a core subunit of the exosome. Because loss-of-function mutations in CER7 result in reduced expression of the wax biosynthetic gene CER3, we proposed that CER7 is involved in degrading a messenger RNA encoding a CER3 repressor. To identify this putative repressor, we performed a cer7 suppressor screen that resulted in the isolation of the posttranscriptional gene-silencing components RNA-DEPENDENT RNA POLYMERASE1 and SUPPRESSOR OF GENE SILENCING3, indicating that small RNAs regulate CER3 expression. To establish the identity of the effector RNA species and determine whether these RNAs control CER3 transcript levels directly, we cloned additional genes identified in our suppressor screen and performed next-generation sequencing of small RNA populations that differentially accumulate in the cer7 mutant in comparison with the wild type. Our results demonstrate that the trans-acting small interfering RNA class of small RNAs are the effector molecules involved in direct silencing of CER3 and that the expression of five additional genes (EARLY RESPONSE TO DEHYDRATION14, AUXIN RESISTANT1, a translation initiation factor SUI1 family protein, and two genes of unknown function) is controlled by both CER7 and trans-acting small interfering RNAs.

  3. ZBRK1 acts as a metastatic suppressor by directly regulating MMP9 in cervical cancer.

    2010-01-01

    The BRCA1-interacted transcriptional repressor ZBRK1 has been associated with antiangiogenesis, but direct evidence of a tumor suppressor role has been lacking. In this study, we provide evidence of such a role in cervical carcinoma. ZBRK1 levels in cervical tumor cells were significantly lower than in normal cervical epithelial cells. In HeLa cervical cancer cells, enforced expression inhibited malignant growth, invasion, and metastasis in a variety of in vitro and in vivo assays. Expression of the metalloproteinase MMP9, which is known to be an important driver of invasion and metastasis, was found to be inversely correlated with ZBRK1 in tumor tissues and a target for repression in tumor cells. Our findings suggest that ZBRK1 acts to inhibit metastasis of cervical carcinoma, perhaps by modulating MMP9 expression.

  4. The Texas space flight liability act and efficient regulation for the private commercial space flight era

    NASA Astrophysics Data System (ADS)

    Johnson, Christopher D.

    2013-12-01

    In the spring of 2011, the American state of Texas passed into law an act limiting the liability of commercial space flight entities. Under it, those companies would not be liable for space flight participant injuries, except in cases of intentional injury or injury proximately caused by the company's gross negligence. An analysis within the framework of international and national space law, but especially informed by the academic discipline of law and economics, discusses the incentives of all relevant parties and attempts to understand whether the law is economically "efficient" (allocating resources so as to yield maximum utility), and suited to further the development of the fledgling commercial suborbital tourism industry. Insights into the Texas law are applicable to other states hoping to foster commercial space tourism and considering space tourism related legislation.

  5. The Clean Air Act strictly regulates electric utility emissions and utilities are reducing their emissions significantly

    SciTech Connect

    Kinsman, J.D.

    1998-12-31

    Electric utility SO{sub 2} and NO{sub x} emissions have been reduced tremendously, beginning before the first deadlines (1995 for SO{sub 2} and 1996 for NO{sub x}) of the 1990 Clean Air Act Amendments. For the Acid Rain Program, EPA reports that: (1) all 445 affected facilities demonstrated 100 percent compliance for both pollutants and even exceeded the compliance targets; (2) the Acid Rain Program has been very successful; and (3) due to these and other controls, air quality has improved in the United States. Furthermore, the new 8-hour ozone standard, the new PM2.5 standards, the EPA`s 22-state regional NO{sub x} program, the Northeast state petitions for upwind NO{sub x} reductions and EPA`s regional haze proposal will likely lead to substantially greater reductions of utility SO{sub 2} and NO{sub x}.

    Yeomans, Martin R.; Brace, Aaron

    There is increasing evidence that individual differences in tendency to overeat relate to impulsivity, possibly by increasing reactivity to food-related cues in the environment. This study tested whether acute exposure to food cues enhanced impulsive and risky responses in women classified on tendency to overeat, indexed by scores on the three factor eating questionnaire disinhibition (TFEQ-D), restraint (TFEQ-R) and hunger scales. Ninety six healthy women completed two measures of impulsive responding (delayed discounting, DDT and a Go No-Go, GNG, task) and a measure of risky decision making (the balloon analogue risk task, BART) as well as questionnaire measures of impulsive behaviour either after looking at a series of pictures of food or visually matched controls. Impulsivity (DDT) and risk-taking (BART) were both positively associated with TFEQ-D scores, but in both cases this effect was exacerbated by prior exposure to food cues. No effects of restraint were found. TFEQ-D scores were also related to more commission errors on the GNG, while restrained women were slower on the GNG, but neither effect was modified by cue exposure. Overall these data suggest that exposure to food cues act to enhance general impulsive responding in women at risk of overeating and tentatively suggest an important interaction between tendency for impulsive decision making and food cues that may help explain a key underlying risk factor for overeating.

    2001-01-01

    The polyadenylation signal of rice tungro bacilliform virus (RTBV) was characterized by mutational and deletion analysis. The cis-acting signals required to direct polyadenylation conformed to what is known for plant poly(A) signals in general and were very similar to those of the related cauliflower mosaic virus. Processing was directed by a canonical AAUAAA poly(A) signal, an upstream UG-rich region considerably enhanced processing efficiency, and sequences downstream of the cleavage site were not required. When present at the end of a transcription unit, the cis-acting signals for 3′-end processing were highly efficient in both monocot (rice) and dicot (Nicotiana plumbaginifolia) protoplasts. In a promoter-proximal position, as in the viral genome, the signal was also efficiently processed in rice protoplasts, giving rise to an abundant “short-stop” (SS-) RNA. The proportion of SS-RNA was considerably lower in N. plumbaginifolia protoplasts. In infected plants, SS-RNA was hardly detectable, suggesting either that SS-RNA is unstable in infected plants or that read-through of the promoter-proximal poly(A) site is very efficient. SS-RNA is readily detectable in transgenic rice plants (A. Klöti, C. Henrich, S. Bieri, X. He, G. Chen, P. K. Burkhardt, J. Wünn, P. Lucca, T. Hohn, I. Potrylus, and J. Fütterer, 1999. Plant Mol. Biol. 40:249–266), thus the absence of SS-RNA in infected plants can be attributed to poly(A) site bypass in the viral context to ensure production of the full-length pregenomic viral RNA. RTBV poly(A) site suppression thus depends both on context and the expression system; our results suggest that the circular viral minichromosome directs assembly of a transcription-processing complex with specific properties to effect read-through of the promoter-proximal poly(A) signal.

    The identity of the cell type responsive to sclerostin, a negative regulator of bone mass, is unknown. Since sclerostin is expressed in vivo by mineral-embedded osteocytes, we tested the hypothesis that sclerostin would regulate the behavior of cells actively involved in mineralization in adult bone, the preosteocyte. Differentiating cultures of human primary osteoblasts exposed to recombinant human sclerostin (rhSCL) for 35 days displayed dose- and time-dependent inhibition of in vitro mineralization, with late cultures being most responsive in terms of mineralization and gene expression. Treatment of advanced (day 35) cultures with rhSCL markedly increased the expression of the preosteocyte marker E11 and decreased the expression of mature markers DMP1 and SOST. Concomitantly, matrix extracellular phosphoglycoprotein (MEPE) expression was increased by rhSCL at both the mRNA and protein levels, whereas PHEX was decreased, implying regulation through the MEPE-ASARM axis. We confirmed that mineralization by human osteoblasts is exquisitely sensitive to the triphosphorylated ASARM-PO4 peptide. Immunostaining revealed that rhSCL increased the endogenous levels of MEPE-ASARM. Importantly, antibody-mediated neutralization of endogenous MEPE-ASARM antagonized the effect of rhSCL on mineralization, as did the PHEX synthetic peptide SPR4. Finally, we found elevated Sost mRNA expression in the long bones of HYP mice, suggesting that sclerostin may drive the increased MEPE-ASARM levels and mineralization defect in this genotype. Our results suggest that sclerostin acts through regulation of the PHEX/MEPE axis at the preosteocyte stage and serves as a master regulator of physiologic bone mineralization, consistent with its localization in vivo and its established role in the inhibition of bone formation.

    The cyclic AMP receptor protein family of transcription factors regulates various metabolic pathways in bacteria, and also play roles in response to environmental changes. Here, we identify four homologs of the CRP family in Deinococcus radiodurans, one of which tolerates extremely high levels of oxidative stress and DNA-damaging reagents. Transcriptional levels of CRP were increased under hydrogen peroxide (H2O2) treatment during the stationary growth phase, indicating that CRPs function in response to oxidative stress. By constructing all CRP single knockout mutants, we found that the dr0997 mutant showed the lowest tolerance toward H2O2, ultraviolet radiation, ionizing radiation, and mitomycin C, while the phenotypes of the dr2362, dr0834, and dr1646 mutants showed slight or no significant differences from those of the wild-type strain. Taking advantage of the conservation of the CRP-binding site in many bacteria, we found that transcription of 18 genes, including genes encoding chromosome-partitioning protein (dr0998), Lon proteases (dr0349 and dr1974), NADH-quinone oxidoreductase (dr1506), thiosulfate sulfurtransferase (dr2531), the DNA repair protein UvsE (dr1819), PprA (dra0346), and RecN (dr1447), are directly regulated by DR0997. Quantitative real-time polymerase chain reaction (qRT-PCR) analyses showed that certain genes involved in anti-oxidative responses, DNA repair, and various cellular pathways are transcriptionally attenuated in the dr0997 mutant. Interestingly, DR0997 also regulate the transcriptional levels of all CRP genes in this bacterium. These data suggest that DR0997 contributes to the extreme stress resistance of D. radiodurans via its regulatory role in multiple cellular pathways, such as anti-oxidation and DNA repair pathways.

    This action delays for at least six months and not more than one year the applicability date for the regulation governing minimum requirements for benefit claims procedures of group health plans covered by Title I of the Employee Retirement Income Security Act. As published on November 21, 2000, the benefit claims procedure would be applicable to claims filed on or after January 1, 2002. The current action amends the regulation so that it will apply to group health claims filed on or after the first day of the first plan year beginning on or after July 1, 2002, but in no event later than January 1, 2003. This action provides a limited additional period within which group health plan sponsors, administrators, and service providers can bring their claims processing systems into compliance with the new requirements. A postponement of the applicability date with respect to group health claims will allow a more orderly transition to the new standards and will avoid the confusion and additional expense that would be caused if certain pending Congressional bills are enacted before or soon after the original applicability date. This action does not apply to pension plans or plans providing disability or welfare benefits (other than group health). For these plans, the regulation will continue to be applicable to claims filed on or after January 1, 2002.

    Shoot branching requires the establishment of new meristems harboring stem cells; this phenomenon raises questions about the precise regulation of meristematic fate. In seed plants, these new meristems initiate in leaf axils to enable lateral shoot branching. Using live-cell imaging of leaf axil cells, we show that the initiation of axillary meristems requires a meristematic cell population continuously expressing the meristem marker SHOOT MERISTEMLESS (STM). The maintenance of STM expression depends on the leaf axil auxin minimum. Ectopic expression of STM is insufficient to activate axillary buds formation from plants that have lost leaf axil STM expressing cells. This suggests that some cells undergo irreversible commitment to a developmental fate. In more mature leaves, REVOLUTA (REV) directly up-regulates STM expression in leaf axil meristematic cells, but not in differentiated cells, to establish axillary meristems. Cell type-specific binding of REV to the STM region correlates with epigenetic modifications. Our data favor a threshold model for axillary meristem initiation, in which low levels of STM maintain meristematic competence and high levels of STM lead to meristem initiation. PMID:27398935

    Phospholipase C gamma-2 (PLCγ2)-dependent calcium (Ca2+) oscillations are indispensable for nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) activation and downstream gene transcription driving osteoclastogenesis during skeletal remodeling and pathological bone loss. Here we describe, to our knowledge, the first known function of transmembrane protein 178 (Tmem178), a PLCγ2 downstream target gene, as a critical modulator of the NFATc1 axis. In surprising contrast to the osteopetrotic phenotype of PLCγ2−/− mice, Tmem178−/− mice are osteopenic in basal conditions and are more susceptible to inflammatory bone loss, owing to enhanced osteoclast formation. Mechanistically, Tmem178 localizes to the ER membrane and regulates RANKL-induced Ca2+ fluxes, thus controlling NFATc1 induction. Importantly, down-regulation of Tmem178 is observed in human CD14+ monocytes exposed to plasma from systemic juvenile idiopathic arthritis patients. Similar to the mouse model, reduced Tmem178 expression in human cells correlates with excessive osteoclastogenesis. In sum, these findings identify an essential role for Tmem178 to maintain skeletal mass and limit pathological bone loss. PMID:26644563

  14. PP2A and GSK-3beta act antagonistically to regulate active zone development.

    The synapse is composed of an active zone apposed to a postsynaptic cluster of neurotransmitter receptors. Each Drosophila neuromuscular junction comprises hundreds of such individual release sites apposed to clusters of glutamate receptors. Here, we show that protein phosphatase 2A (PP2A) is required for the development of structurally normal active zones opposite glutamate receptors. When PP2A is inhibited presynaptically, many glutamate receptor clusters are unapposed to Bruchpilot (Brp), an active zone protein required for normal transmitter release. These unapposed receptors are not due to presynaptic retraction of synaptic boutons, since other presynaptic components are still apposed to the entire postsynaptic specialization. Instead, these data suggest that Brp localization is regulated at the level of individual release sites. Live imaging of glutamate receptors demonstrates that this disruption to active zone development is accompanied by abnormal postsynaptic development, with decreased formation of glutamate receptor clusters. Remarkably, inhibition of the serine-threonine kinase GSK-3beta completely suppresses the active zone defect, as well as other synaptic morphology phenotypes associated with inhibition of PP2A. These data suggest that PP2A and GSK-3beta function antagonistically to control active zone development, providing a potential mechanism for regulating synaptic efficacy at a single release site.

    Extracellular adhesion molecules and their neuronal receptors guide the growth and branching of axons and dendrites. Growth cones are attracted to intermediate targets, but they must switch their response upon arrival so that they can move away and complete the next stage of growth. Here, we show that KPC-1, a C. elegans Furin homolog, regulates the level of the branching receptor DMA-1 on dendrites by targeting it to late endosomes. In kpc-1 mutants, the level of DMA-1 is abnormally high on dendrites, resulting in trapping of dendrites at locations where a high level of the cognate ligand, the adhesion molecule SAX-7/L1, is present. The misregulation of DMA-1 also causes dendritic self-avoidance defects. Thus, precise regulation of guidance receptors creates flexibility of responses to guidance signals and is critical for neuronal morphogenesis.

    2015-01-01

    Estrogen receptor-α (ERα) is a steroid hormone-sensitive transcription factor that plays a critical role in development of breast cancer. The binding of estrogen to ERα triggers the recruitment of transcriptional co-activators as well as chromatin remodeling factors to estrogen-responsive elements (ERE) of ERα target genes. This process is tightly associated with post-translational modifications (PTMs) of ERα and its co-activators for promotion of transcriptional activation, which leads to proliferation of a large subset of breast tumor cells. These PTMs include phosphorylation, acetylation, methylation, and conjugation by ubiquitin and ubiquitin-like proteins. Ubiquitin-fold modifier 1 (UFM1), one of ubiquitin-like proteins, has recently been shown to be ligated to activating signal co-integrator 1 (ASC1), which acts as a transcriptional co-activator of nuclear receptors. Here, we discuss the mechanistic connection between ASC1 modification by UFM1 and ERα transactivation, and highlight how the interplay of these processes is involved in development of breast cancer. We also discuss potential use of UFM1-conjugating system as therapeutic targets against not only breast cancer but also other nuclear receptor-mediated cancers. PMID:25852645

    The secreted leucine-rich glioma inactivated 1 (LGI1) protein is an important actor for human seizures of both genetic and autoimmune etiology: mutations in LGI1 cause inherited temporal lobe epilepsy, while LGI1 is involved in antibody-mediated encephalitis. Remarkably, Lgi1-deficient (Lgi1−/−) mice recapitulate the epileptic disorder and display early-onset spontaneous seizures. To understand how Lgi1-deficiency leads to seizures during postnatal development, we here investigated the early functional and structural defects occurring before seizure onset in Lgi1−/− mice. We found an increased excitatory synaptic transmission in hippocampal slices from Lgi1−/− mice. No structural alteration in the morphology of pyramidal cell dendrites and synapses was observed at this stage, indicating that Lgi1-deficiency is unlikely to trigger early developmental abnormalities. Consistent with the presynaptic subcellular localization of the protein, Lgi1-deficiency caused presynaptic defects, with no alteration in postsynaptic AMPA receptor activity in Lgi1−/− pyramidal cells before seizure onset. Presynaptic dysfunction led to increased synaptic glutamate levels, which were associated with hyperexcitable neuronal networks. Altogether, these data show that Lgi1 acts presynaptically as a negative modulator of excitatory synaptic transmission during early postnatal development. We therefore here reveal that increased presynaptic glutamate release is a key early event resulting from Lgi1-deficiency, which likely contributes to epileptogenesis. PMID:26878798

    Angiogenesis is regulated by numerous activators and inhibitors, including prostanoids. Although many studies have identified their roles in inflammation, regulatory functions of prostanoids in angiogenesis are poorly understood. Here, we compared the activation of angiogenesis in vitro by two prostanoids with important vascular roles: prostaglandin E2 (PGE2) - thought to be the most important prostanoid activator of angiogenesis - and prostaglandin I2 (prostacyclin or PGI2), whose receptors are predominantly expressed in endothelial cells. Both of these prostanoids activate G-protein coupled receptors: EP1, EP2, EP3 and EP4 by PGE2 and IP by prostacyclin. Human umbilical vein endothelial cells (HUVECs) were used to characterize two pivotal pro-angiogenic processes in vitro: cell migration (using the matrigel droplet assay developed in our laboratory) and "tube formation" (a widely accepted method of assessing formation of blood vessel precursors). The suppression of cell migration and tube formation by the IP-specific antagonist CAY10441 was more extensive (~80%) than by the EP4-specific antagonist L-161,982 (~20%). AH6809, an antagonist of EP1, EP2 and EP3 receptors did not significantly suppress angiogenesis. Expression of the pro-angiogenic receptors KDR and Tie-2 in HUVECs was preferentially suppressed by antagonism of IP and EP4 receptors, respectively. EP4 and IP receptor agonists elicited biphasic actions on angiogenic processes in which there was activation at low concentration, and rapid desensitization at high concentrations - a characteristic common to many G-protein coupled receptors. Together these findings suggest that the prostacyclin-IP pathway plays a major role in the regulation of pro-angiogenic processes in HUVECs.

    Two models of transsphincteric flow and a model evaluating pumping activity were established in the anesthetized Australian brush-tailed possum to determine whether the sphincter of Oddi (SO) acts as a resistor or as a pump. A simple model of transsphincteric flow (inflow only) demonstrated that at physiological common bile duct (CBD) pressure, 9.5 +/- 0.3 cmH2O (n = 7), transsphincteric flow occurred between SO pressure waves (n = 10). A second more complex transsphincteric flow model was established that permitted simultaneous measurements of inflow, outflow, CBD pressure, SO basal pressure, SO contraction frequency, and amplitude. At physiological CBD pressure, inflow always equaled outflow (157.0 +/- 11.2 and 156.4 +/- 11.4 microliters/min, respectively; n = 7). The SO displayed regular contractions superimposed on a basal pressure of 1.1 +/- 0.4 mmHg. Contraction amplitude was 12.6 +/- 3.0 mmHg and the frequency was 3.6 +/- 0.4 contractions/min (n = 7). Pressure waves recorded in the CBD corresponded to the SO contractions and reflected SO activity. Transsphincteric flow occurred between SO contractions and was obstructed by these contractions. Stimulation of SO activity (basal pressure and contraction frequency) with intra-arterial injections of motilin (200 ng/kg) or erythromycin (200 micrograms/kg) abolished transsphincteric flow. Reduction in SO contraction frequency to 72.7 +/- 7.2% (P < 0.01, paired t test) after administration of Cisapride (2 mg/kg iv) increased transsphincteric flow to 147.6 +/- 12.3% (n = 7, P < 0.05, paired t test). In six possums, possible SO pumping action was evaluated. A manometer was connected to the CBD, and a second manometer was connected to the duodenum surrounding the papilla.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1443142

  18. Transferrin synthesis by small cell lung cancer cells acts as an autocrine regulator of cellular proliferation.

    Since transferrin is required for cellular proliferation, we investigated transferrin synthesis by a small cell lung cancer line (NCI-H510) that survives in serum-free media without added transferrin. Immunoassays for human transferrin demonstrated that these cells contained immunoreactive human transferrin. Immunofluorescence studies showed that the protein is expressed on the surface of cells, presumably bound to transferrin receptor. Media conditioned by NCI-H510 cells support proliferation of human leukemic cells that would not survive in media lacking transferrin. [35S]Methionine incorporation documented transferrin synthesis by NCI-H510 cells as well as three other small cell lines. Transferrin synthesis by NCI-H510 cells increased more than 10-fold when cells entered active phases of the cell cycle, and this increase was seen before large increases in transferrin-receptor expression. Further experiments examining the effects of agents that affect iron metabolism show that the addition of transferrin-iron or hemin to the media is associated with a more rapid initial rate of proliferation and lower rates of transferrin synthesis than control cells. Gallium salts, which inhibit iron uptake, inhibited proliferation of these cells. If the cells recovered from this effect, transferrin synthesis remained greatly increased compared to control. We conclude that transferrin synthesis by these malignant cells is ultimately related to an iron requirement for cellular proliferation. It appears that this synthesized transferrin acts as part of an important autocrine mechanism permitting proliferation of these cells, and perhaps permitting tumor cell growth in vivo in areas not well vascularized.

  19. The glucocorticoid receptor is a key regulator of the decision between self-renewal and differentiation in erythroid progenitors.

    During development and in regenerating tissues such as the bone marrow, progenitor cells constantly need to make decisions between proliferation and differentiation. We have used a model system, normal erythroid progenitors of the chicken, to determine the molecular players involved in making this decision. The molecules identified comprised receptor tyrosine kinases (c-Kit and c-ErbB) and members of the nuclear hormone receptor superfamily (thyroid hormone receptor and estrogen receptor). Here we identify the glucocorticoid receptor (GR) as a key regulator of erythroid progenitor self-renewal (i.e. continuous proliferation in the absence of differentiation). In media lacking a GR ligand or containing a GR antagonist, erythroid progenitors failed to self-renew, even if c-Kit, c-ErbB and the estrogen receptor were activated simultaneously. To induce self-renewal, the GR required the continuous presence of an activated receptor tyrosine kinase and had to cooperate with the estrogen receptor for full activity. Mutant analysis showed that DNA binding and a functional AF-2 transactivation domain are required for proliferation stimulation and differentiation arrest. c-myb was identified as a potential target gene of the GR in erythroblasts. It could be demonstrated that delta c-Myb, an activated c-Myb protein, can functionally replace the GR. PMID:9029148

    The transition from vegetative growth to floral meristems in higher plants is regulated through the integration of internal cues and environmental signals. We were interested to examine the molecular mechanism of flowering in the day-neutral plant tomato (Solanum lycopersicum L.) and the effect of environmental conditions on tomato flowering. Analysis of the tomato genome uncovered 13 PEBP (phosphatidylethanolamine-binding protein) genes, and found six of them were FT-like genes which named as SlSP3D, SlSP6A, SlSP5G, SlSP5G1, SlSP5G2, and SlSP5G3. Six FT-like genes were analyzed to clarify their functional roles in flowering using transgenic and expression analyses. We found that SlSP5G, SlSP5G2, and SlSP5G3 proteins were floral inhibitors whereas only SlSP3D/SFT (SINGLE FLOWER TRUSS) was a floral inducer. SlSP5G was expressed at higher levels in long day (LD) conditions compared to short day (SD) conditions while SlSP5G2 and SlSP5G3 showed the opposite expression patterns. The silencing of SlSP5G by VIGS (Virus induced gene silencing) resulted in tomato plants that flowered early under LD conditions and the silencing of SlSP5G2 and SlSP5G3 led to early flowering under SD conditions. The higher expression levels of SlSP5G under LD conditions were not seen in phyB1 mutants, and the expression levels of SlSP5G2 and SlSP5G3 were increased in phyB1 mutants under both SD and LD conditions compared to wild type plants. These data suggest that SlSP5G, SlSP5G2, and SlSP5G3 are controlled by photoperiod, and the different expression patterns of FT-like genes under different photoperiod may contribute to tomato being a day neutral plant. In addition, PHYB1 mediate the expression of SlSP5G, SlSP5G2, and SlSP5G3 to regulate flowering in tomato.

    ZBRK1, named after its structure of Zinc finger and BRCA1-interacting protein with KRAB domain-1 (ZBRK1), is a transcriptional repressor modulated by BRCA1. Recent evidence also indicated that ZBRK1 collaborated with BRCA1/CtIP to repress angiopoietin-1 expression in preventing over enlargement of blood vessels in tumors, suggesting that ZBRK1 may exert a critical role during tumor progression. However, a direct role of ZBRK1 in tumorigenesis and tumor progression remains obscure. Here we found that ZBRK1 expression was significantly lower in highly malignant cervical cancer cells than the counterpart normal tissue. Ectopic expression of ZBRK1 in HeLa cells significantly inhibits its neoplastic phenotypes including cell proliferation, soft-agar colony formation and tumor growth in nude mice. To explore its mechanisms, analyses of gene expression patterns of these cells revealed groups of genes not only critical for cell proliferation but also for cell motility being down regulated. Consistently, ectopic expression of ZBRK1 inhibits HeLa cells migration in cell migration and invasion assays in culture and metastatic assay in mice. Importantly, ZBRK1 directly represses transcription of the metastatic gene, MMP9, and the loss of ZBRK1 expression is inversely correlated to the elevated expression of MMP9 in cervical cancer specimens. Taken together, these results indicate that ZBRK1 may have a critical role as a tumor suppressor, especially in metastasis, through directly modulating metastatic genes such as MMP9. PMID:19996286

    In humans, mutations in ATGL lead to TG accumulation in LDs of most tissues and cells, including peripheral blood leukocytes. This pathologic condition is called Jordans’ anomaly, in which functional consequences have not been investigated. In the present study, we tested the hypothesis that ATGL plays a role in leukocyte LD metabolism and immune cell function. Similar to humans with loss-of-function mutations in ATGL, we found that global and myeloid-specific Atgl−/− mice exhibit Jordans’ anomaly with increased abundance of intracellular TG-rich LDs in neutrophil granulocytes. In a model of inflammatory peritonitis, lipid accumulation was also observed in monocytes and macrophages but not in eosinophils or lymphocytes. Neutrophils from Atgl−/− mice showed enhanced immune responses in vitro, which were more prominent in cells from global compared with myeloid-specific Atgl−/− mice. Mechanistically, ATGL−/− as well as pharmacological inhibition of ATGL led to an impaired release of lipid mediators from neutrophils. These findings demonstrate that the release of lipid mediators is dependent on the liberation of precursor molecules from the TG-rich pool of LDs by ATGL. Our data provide mechanistic insights into Jordans’ anomaly in neutrophils and suggest that ATGL is a potent regulator of immune cell function and inflammatory diseases. PMID:26109679

  6. Bilirubin acts as an endogenous regulator of inflammation by disrupting adhesion molecule-mediated leukocyte migration

    2016-01-01

    There is a growing body of evidence that bilirubin, which is generated during the physiological breakdown of heme, exerts potent anti-inflammatory effects. Previous work by our group suggests that bilirubin is able to suppress inflammatory responses by preventing the migration of leukocytes into target tissues through disruption of vascular cell adhesion molecule-1 (VCAM-1)-dependent cell signaling. As VCAM-1 is an important mediator of tissue injury in the dextran sodium sulfate (DSS) murine model of inflammatory colitis, we examined whether bilirubin prevents colonic injury in DSS-treated mice. As anticipated, bilirubin-treated animals manifested significantly less colonic injury and reduced infiltration of inflammatory cells into colon tissues. We further observed that bilirubin administration was associated with a reduced number of eosinophils and monocytes in the small intestine, with a corresponding increase in peripheral blood eosinophilia, regardless of whether mice received DSS. These findings suggest that bilirubin impairs the normal migration of eosinophils into intestinal tissues, as supported by in vitro experiments showing that bilirubin blocks the VCAM-1-dependent movement of Jurkat cells across human endothelial cell monolayers. Taken together, our findings support that bilirubin ameliorates DSS-induced colitis and disrupts the physiological trafficking of leukocytes to the intestine by preventing transmigration across the vascular endothelium, potentially through the inhibition VCAM-1-mediated signaling. Our findings raise the possibility that bilirubin functions as an endogenous regulator of inflammatory responses. PMID:26925435

    Regulation of hypothalamic–pituitary–adrenocortical (HPA) axis activity by stress is a fundamental survival mechanism and HPA-dysfunction is implicated in psychiatric disorders. Adverse early life experiences, e.g. poor maternal care, negatively influence brain development and programs an abnormal stress response by encoding long-lasting molecular changes, which may extend to the next generation. How HPA-dysfunction leads to the development of affective disorders is complex, but may involve GABAA receptors (GABAARs), as they curtail stress-induced HPA axis activation. Of particular interest are endogenous neurosteroids that potently modulate the function of GABAARs and exhibit stress-protective properties. Importantly, neurosteroid levels rise rapidly during acute stress, are perturbed in chronic stress and are implicated in the behavioural changes associated with early-life adversity. We will appraise how GABAAR-active neurosteroids may impact on HPA axis development and the orchestration of the stress-evoked response. The significance of these actions will be discussed in the context of stress-associated mood disorders. PMID:24929099

    Interhomolog crossovers promote proper chromosome segregation during meiosis and are formed by the regulated repair of programmed double-strand breaks. This regulation requires components of the synaptonemal complex (SC), a proteinaceous structure formed between homologous chromosomes. In yeast, SC formation requires the “ZMM” genes, which encode a functionally diverse set of proteins, including the transverse filament protein, Zip1. In wild-type meiosis, Zmm proteins promote the biased resolution of recombination intermediates into crossovers that are distributed throughout the genome by interference. In contrast, noncrossovers are formed primarily through synthesis-dependent strand annealing mediated by the Sgs1 helicase. This work identifies a conserved region on the C terminus of Zip1 (called Zip1 4S), whose phosphorylation is required for the ZMM pathway of crossover formation. Zip1 4S phosphorylation is promoted both by double-strand breaks (DSBs) and the meiosis-specific kinase, MEK1/MRE4, demonstrating a role for MEK1 in the regulation of interhomolog crossover formation, as well as interhomolog bias. Failure to phosphorylate Zip1 4S results in meiotic prophase arrest, specifically in the absence of SGS1. This gain of function meiotic arrest phenotype is suppressed by spo11Δ, suggesting that it is due to unrepaired breaks triggering the meiotic recombination checkpoint. Epistasis experiments combining deletions of individual ZMM genes with sgs1-md zip1-4A indicate that Zip1 4S phosphorylation functions prior to the other ZMMs. These results suggest that phosphorylation of Zip1 at DSBs commits those breaks to repair via the ZMM pathway and provides a mechanism by which the crossover/noncrossover decision can be dynamically regulated during yeast meiosis.

    Programmed cell death (PCD) in multicellular organisms is a vital process in growth, development, and stress responses that contributes to the formation of tissues and organs. Although numerous studies have defined the molecular participants in apoptotic and PCD cascades, successful identification of early master regulators that target specific cells to live or die is limited. Using Zea mays somatic embryogenesis as a model system, we report that the expressions of two plant hemoglobin (Hb) genes (ZmHb1 and ZmHb2) regulate the cell survival/death decision that influences somatic embryogenesis through their cell-specific localization patterns. Suppression of either of the two ZmHbs is sufficient to induce PCD through a pathway initiated by elevated NO and Zn2+ levels and mediated by production of reactive oxygen species. The effect of the death program on the fate of the developing embryos is dependent on the localization patterns of the two ZmHbs. During somatic embryogenesis, ZmHb2 transcripts are restricted to a few cells anchoring the embryos to the subtending embryogenic tissue, whereas ZmHb1 transcripts extend to several embryonic domains. Suppression of ZmHb2 induces PCD in the anchoring cells, allowing the embryos to develop further, whereas suppression of ZmHb1 results in massive PCD, leading to abortion. We conclude that regulation of the expression of these ZmHbs has the capability to determine the developmental fate of the embryogenic tissue during somatic embryogenesis through their effect on PCD. This unique regulation might have implications for development and differentiation in other species. PMID:24784758

    Noonan syndrome is one of the most common causes of human congenital heart disease and is frequently associated with missense mutations in the protein phosphatase SHP-2. Interestingly, patients with acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), juvenile myelomonocytic leukemia (JMML) and LEOPARD syndrome frequently carry a second, somatically introduced subset of missense mutations in SHP-2. To determine the cellular and molecular mechanisms by which SHP-2 regulates heart development and, thus, understand how Noonan-associated mutations affect cardiogenesis, we introduced SHP-2 encoding the most prevalent Noonan syndrome and JMML mutations into Xenopus embryos. Resulting embryos show a direct relationship between a Noonan SHP-2 mutation and its ability to cause cardiac defects in Xenopus; embryos expressing Noonan SHP-2 mutations exhibit morphologically abnormal hearts, whereas those expressing an SHP-2 JMML-associated mutation do not. Our studies indicate that the cardiac defects associated with the introduction of the Noonan-associated SHP-2 mutations are coupled with a delay or arrest of the cardiac cell cycle in M-phase and a failure of cardiomyocyte progenitors to incorporate into the developing heart. We show that these defects are a result of an underlying malformation in the formation and polarity of cardiac actin fibers and F-actin deposition. We show that these defects can be rescued in culture and in embryos through the inhibition of the Rho-associated, coiled-coil-containing protein kinase 1 (ROCK), thus demonstrating a direct relationship between SHP-2(N308D) and ROCK activation in the developing heart.

    FoxG1 is a conserved transcriptional repressor that plays a key role in the specification, proliferation and differentiation of the telencephalon, and is expressed from the earliest stages of telencephalic development through to the adult. How the interaction with co-factors might influence the multiplicity and diversity of FoxG1 function is not known. Here, we show that interaction of FoxG1 with TLE2, a Xenopus tropicalis co-repressor of the Groucho/TLE family, is crucial for regulating the early activity of FoxG1. We show that TLE2 is co-expressed with FoxG1 in the ventral telencephalon from the early neural plate stage and functionally cooperates with FoxG1 in an ectopic neurogenesis assay. FoxG1 has two potential TLE binding sites: an N-terminal eh1 motif and a C-terminal YWPMSPF motif. Although direct binding seems to be mediated by the N-terminal motif, both motifs appear important for functional synergism. In the neurogenesis assay, mutation of either motif abolishes functional cooperation of TLE2 with FoxG1, whereas in the forebrain deletion of both motifs renders FoxG1 unable to induce the ventral telencephalic marker Nkx2.1. Knocking down either FoxG1 or TLE2 disrupts the development of the ventral telencephalon, supporting the idea that endogenous TLE2 and FoxG1 work together to specify the ventral telencephalon.

    Immunomodulatory drugs (IMiDs) such as thalidomide, lenalidomide, and pomalidomide are efficacious in the treatment of multiple myeloma and significantly prolong their survival. However, the mechanisms of such effects of IMiDs have not been fully elucidated. Recently, cereblon has been identified as a target binding protein of thalidomide. Lenalidomide-resistant myeloma cell lines often lose the expression of cereblon, suggesting that IMiDs act as an anti-myeloma agent through interacting with cereblon. Cereblon binds to damaged DNA-binding protein and functions as a ubiquitin ligase, inducing degradation of IKZF1 and IKZF3 that are essential transcription factors for B and T cell development. Degradation of both IKZF1 and IKZF3 reportedly suppresses myeloma cell growth. Here, we found that IMiDs act as inhibitors of DNA methyltransferases (DMNTs). We previously reported that PU.1, which is an ETS family transcription factor and essential for myeloid and lymphoid development, functions as a tumor suppressor in myeloma cells. PU.1 induces growth arrest and apoptosis of myeloma cell lines. In this study, we found that low-dose lenalidomide and pomalidomide up-regulate PU.1 expression through inducing demethylation of the PU.1 promoter. In addition, IMiDs inhibited DNMT1, DNMT3a, and DNMT3b activities in vitro. Furthermore, lenalidomide and pomalidomide decreased the methylation status of the whole genome in myeloma cells. Collectively, IMiDs exert demethylation activity through inhibiting DNMT1, 3a, and 3b, and up-regulating PU.1 expression, which may be one of the mechanisms of the anti-myeloma activity of IMiDs.

    Generation of new adipocytes plays a major role in the development of obesity. We previously have shown that transcriptional repressor factor that binds to IST (FBI)-1 exerts a dual effect in the process of adipogenesis by inhibiting proliferation and promoting differentiation of preadipocytes. The aim of the present study was to identify FBI-1 regulated molecular effectors that could account for these effects. Overexpressing FBI-1 in preadipocytes resulted in reduced expression of the cell cycle regulator cyclin A, which may explain FBI-1 induced inhibition of proliferation. Interestingly, FBI-1 repressed cyclin A promoter activity through an indirect mechanisms that did not involve direct binding of FBI-1 to the promoter sequence, but rather FBI-1 inhibition of transcriptional activator Sp1 binding to a regulatory element at -452 to -443. We also show that FBI-1 promotes terminal preadipocyte differentiation through a mechanism involving decreased levels of expression of the PPARgamma inhibitor E2F-4. FBI-1 significantly reduced E2F-4 promoter activity. Contrary to cyclin A, we found FBI-1-induced repression of E2F-4 is mediated by a direct mechanism via a FBI-1 regulatory element at -11 to -5. As function of transcriptional repressors normally depends on the presence of regulatory co-factors we also performed expression profiling of potential FBI-1 co-repressors throughout adipogenesis. In these experiments Sin3A and histon deacetylase (HDAC)-1 showed a similar expression pattern compared to FBI-1. Strikingly, co-immunoprecipitation studies revealed that FBI-1 binds Sin3A and HDAC-1 to form a repressor complex. Furthermore, by mutational analysis the amino terminal Poxvirus (POZ) domain of FBI-1 was found to be important for Sin3A and HDAC-1 binding. Taken together, FBI-1 is the first transcriptional repressor shown to act as a dual regulator in adipogenesis exerting repressor activities on target genes by both, direct and indirect mechanisms.

    Eukaryotic nuclei contain regions of differentially staining chromatin (heterochromatin), which remain condensed throughout the cell cycle and are largely transcriptionally silent. RNAi knockdown of the highly conserved heterochromatin protein HP1 in Drosophila was previously shown to preferentially reduce male viability. Here we report a similar phenotype for the telomeric partner of HP1, HOAP, and roles for both proteins in regulating the Drosophila sex determination pathway. Specifically, these proteins regulate the critical decision in this pathway, firing of the establishment promoter of the masterswitch gene, Sex-lethal (Sxl). Female-specific activation of this promoter, SxlPe, is essential to females, as it provides SXL protein to initiate the productive female-specific splicing of later Sxl transcripts, which are transcribed from the maintenance promoter (SxlPm) in both sexes. HOAP mutants show inappropriate SxlPe firing in males and the concomitant inappropriate splicing of SxlPm-derived transcripts, while females show premature firing of SxlPe. HP1 mutants, by contrast, display SxlPm splicing defects in both sexes. Chromatin immunoprecipitation assays show both proteins are associated with SxlPe sequences. In embryos from HP1 mutant mothers and Sxl mutant fathers, female viability and RNA polymerase II recruitment to SxlPe are severely compromised. Our genetic and biochemical assays indicate a repressing activity for HOAP and both activating and repressing roles for HP1 at SxlPe. PMID:21695246

    Air Products is carrying out a scope of work under Phase 5 of the ITM Oxygen Cooperative Agreement to design, build, and operate a ceramic membrane fabrication facility (the “CerFab”) to enable production of membrane modules to supply a conceptual 2000 ton per day (TPD) ITM Oxygen facility (the “ITM Oxygen Development Facility”), and to perform supporting development tasks in materials development an engineering development toward industrial, carbon capture and sequestration applications. Air Products is executing this project under the American Recovery and Reinvestment Act (ARRA) with the objective to accelerate the adoption of ITM Oxygen technology to help meet the country’s goals for deploying clean power plants. The objective of this Topical Report is to address the requirements of Decision Point 2, which pertains to progress in Materials Development, Engineering Development, and construction of the CerFab, with an emphasis on establishing the environmental permitting required prior to the next Decision Point. In the area of Materials Development, Air Products has specified a high pressure dilatometer system which will enable measurements of material expansion of ITM ceramic compounds at very high oxygen partial pressures consistent with CCS applications. Also in this area, Ceramatec has made significant progress in developing Advanced Architecture wafers and modules by advancing in parallel with two production methods of the Advanced Architecture components and determining the appropriate equipment required to make these components at high volume in the CerFab. Work in this area continues to refine the CerFab requirements. Under Engineering Development, Air Products has developed various concepts around use of ITM in industrial applications to reduce carbon footprint though process integrations that result in less fuel requirement. Air Products also developed notions around hybrid cryogenic air separation plants with ITM Oxygen plants for scale

    In 1976, under section 4(e) of the Toxic Substances Control Act (TSCA), the US Congress created the TSCA Interagency Testing Committee (ITC) to decide which chemicals should be recommended to the Administrator of the US Environmental Protection Agency for testing. In 1988, under the Canadian Environmental Protection Act (CEPA), the Government of Canada created the Domestic Substances List and Priority Substances List. This paper briefly describes the ITC, the different ITC testing decisions and a few of the ITC`s 11,150 testing decisions for the 21,413 chemicals on the CEPA Domestic Substances List and some of the 24 testing decisions for the 44 chemicals and chemical groups on the CEPA.

  3. Evidence implicating the 5' untranslated region of Listeria monocytogenes actA in the regulation of bacterial actin-based motility.

    The ActA protein of Listeria monocytogenes is a major virulence factor, essential for the recruitment and polymerization of host actin filaments that lead to intracellular motility and cell-to-cell spread of bacteria within the infected host. The expression of actA is tightly regulated and is strongly induced only when L. monocytogenes is within the host cytosol. Intracellular induction of actA expression is mediated through a single promoter element that directs the expression of a messenger RNA with a long (150 bp) 5' untranslated region (UTR). Deletion of the actA+3 to +130 upstream region was found to result in bacterial mutants that were no longer capable of intracellular actin recruitment or cell-to-cell spread, thus indicating that this region is important for actA expression. L. monocytogenes strains that contained smaller deletions (21-23 bp) within the actA upstream region demonstrated a range of actA expression levels that coincided with the amount of bacterial cell-to-cell spread observed within infected monolayers. A correlation appeared to exist between levels of actA expression and the ability of L. monocytogenes to transition from uniform actin accumulation surrounding individual bacteria (actin clouds) to directional assembly and the formation of actin tails. Bacterial mutants containing deletions that most significantly altered the predicted secondary structure of the actA mRNA 5' UTR had the largest reductions in actA expression. These results suggest that the actA 5' UTR is required for maximal ActA synthesis and that a threshold level of ActA synthesis must be achieved to promote the transition from bacteria-associated actin clouds to directional actin assembly and movement.

  15. Bacillus subtilis glutamine synthetase regulates its own synthesis by acting as a chaperone to stabilize GlnR-DNA complexes.

    PubMed

    Fisher, Susan H; Wray, Lewis V

    2008-01-22

    The Bacillus subtilis GlnR repressor controls gene expression in response to nitrogen availability. Because all GlnR-regulated genes are expressed constitutively in mutants lacking glutamine synthetase (GS), GS is required for repression by GlnR. Feedback-inhibited GS (FBI-GS) was shown to activate GlnR DNA binding with an in vitro electophoretic mobility shift assay (EMSA). The activation of GlnR DNA binding by GS in these experiments depended on the feedback inhibitor glutamine and did not occur with mutant GS proteins defective in regulating GlnR activity in vivo. Although stable GS-GlnR-DNA ternary complexes were not observed in the EMSA experiments, cross-linking experiments showed that a protein-protein interaction occurs between GlnR and FBI-GS. This interaction was reduced in the absence of the feedback inhibitor glutamine and with mutant GS proteins. Because FBI-GS significantly reduced the dissociation rate of the GlnR-DNA complexes, the stability of these complexes is enhanced by FBI-GS. These results argue that FBI-GS acts as a chaperone that activates GlnR DNA binding through a transient protein-protein interaction that stabilizes GlnR-DNA complexes. GS was shown to control the activity of the B. subtilis nitrogen transcription factor TnrA by forming a stable complex between FBI-GS and TnrA that inhibits TnrA DNA binding. Thus, B. subtilis GS is an enzyme with dual catalytic and regulatory functions that uses distinct mechanisms to control the activity of two different transcription factors.

    Neuroprotectin D1 (NPD1), a docosahexaenoic acid (DHA)-derived mediator, induces cell survival in uncompensated oxidative stress (OS), neurodegenerations or ischemic stroke. The molecular principles underlying this protection remain unresolved. We report here that, in retinal pigment epithelial cells, NPD1 induces nuclear translocation and cREL synthesis that, in turn, mediates BIRC3 transcription. NPD1 activates NF-κB by an alternate route to canonical signaling, so the opposing effects of TNFR1 and NPD1 on BIRC3 expression are not due to interaction/s between NF-κB pathways. RelB expression follows a similar pattern as BIRC3, indicating that NPD1 also is required to activate cREL-mediated RelB expression. These results suggest that cREL, which follows a periodic pattern augmented by the lipid mediator, regulates a cluster of NPD1-dependent genes after cREL nuclear translocation. BIRC3 silencing prevents NPD1 induction of survival against OS. Moreover, brain NPD1 biosynthesis and selective neuronal BIRC3 abundance are increased by DHA after experimental ischemic stroke followed by remarkable neurological recovery. Thus, NPD1 bioactivity governs key counter-regulatory gene transcription decisive for retinal and brain neural cell integrity when confronted with potential disruptions of homeostasis. PMID:25633199

  17. Impacts & Compliance Implementation Plans & Required Deviations for Toxic Substance Control Act (TSCA) Regulation of Double Shell Tanks (DST)

    2000-08-22

    In May 2000, the U.S. Department of Energy, Office of River Protection (DOE-ORP) and the U.S. Environmental Protection Agency (EPA) held meetings regarding the management of polychlorinated biphenyls (PCBs) in the Hanford tank waste. It was decided that the radioactive waste currently stored in the double-shell tanks (DSTs) contain waste which will become subject to the Toxic Substance Control Act (TSCA) (40 CFR 761). As a result, DOE-ORP directed the River Protection Project tank farm contractor (TFC) to prepare plans for managing the PCB inventory in the DSTs. Two components of the PCB management plans are this assessment of the operational impacts of TSCA regulation and the identifications of deviations from TSCA that are required to accommodate tank farm unique limitations. This plan provides ORP and CH2M HILL Hanford Group, Inc. (CHG) with an outline of TSCA PCB requirements and their applicability to tank farm activities, and recommends a compliance/implementation approach. Where strict compliance is not possible, the need for deviations from TSCA PCB requirements is identified. The purpose of assembling this information is to enhance the understanding of PCB management requirements, identify operational impacts and select impact mitigation strategies. This information should be useful in developing formal agreements with EPA where required.

    microRNAs (miRNAs), small noncoding RNAs of 19-25 nt, play an important roles in the pathological processes of tumorigenesis. The object of this study was to study the expression and function of miR-203 and to found its target gene in osteosarcoma. In our study, we found the expression level of miR-203 was significantly downregulated in osteosarcoma cell lines and tissues. In addition, overexpression of miR-203 inhibited the osteosarcoma cell proliferation and migration and inhibited Mesenchymal-to-Epithelial reversion Transition (MErT). Moreover, we identified RAB22A as a direct target of miR-203 and RAB22A overexpression blocks the roles of miR-203 in osteosarcoma cell. Furthermore, we demonstrated that RAB22A expression was upregulated in human osteosarcoma cell lines and tissues. Take together, our results demonstrated that miR-203 act as a tumor suppressor miRNA through regulating RAB22A expression and suggested its involvement in osteosarcoma progression and carcinogenesis.

    Aberrant expression of long noncoding RNAs (lncRNAs) is associated with various human cancers. However, the role of lncRNAs in Bcr-Abl-mediated chronic myeloid leukemia (CML) is unknown. In this study, we performed a comprehensive analysis of lncRNAs in human CML cells using an lncRNA cDNA microarray and identified an lncRNA termed lncRNA-BGL3 that acted as a key regulator of Bcr-Abl-mediated cellular transformation. Notably, we observed that lncRNA-BGL3 was highly induced in response to disruption of Bcr-Abl expression or by inhibiting Bcr-Abl kinase activity in K562 cells and leukemic cells derived from CML patients. Ectopic expression of lncRNA-BGL3 sensitized leukemic cells to undergo apoptosis and inhibited Bcr-Abl-induced tumorigenesis. Furthermore, transgenic (TG) mice expressing lncRNA-BGL3 were generated. We found that TG expression of lncRNA-BGL3 alone in mice was sufficient to impair primary bone marrow transformation by Bcr-Abl. Interestingly, we identified that lncRNA-BGL3 was a target of miR-17, miR-93, miR-20a, miR-20b, miR-106a and miR-106b, microRNAs that repress mRNA of phosphatase and tensin homolog (PTEN). Further experiments demonstrated that lncRNA-BGL3 functioned as a competitive endogenous RNA for binding these microRNAs to cross-regulate PTEN expression. Additionally, our experiments have begun to address the mechanism of how lncRNA-BGL3 is regulated in the leukemic cells and showed that Bcr-Abl repressed lncRNA-BGL3 expression through c-Myc-dependent DNA methylation. Taken together, these results reveal that Bcr-Abl-mediated cellular transformation critically requires silence of tumor-suppressor lncRNA-BGL3 and suggest a potential strategy for the treatment of Bcr-Abl-positive leukemia.

  20. End-of-life medical decisions in France: a death certificate follow-up survey 5 years after the 2005 act of parliament on patients’ rights and end of life

    PubMed Central

    2012-01-01

    Background The “Patients’ Rights and End of Life Care” Act came into force in France in 2005. It allows withholding/withdrawal of life-support treatment, and intensified use of medications that may hasten death through a double effect, as long as hastening death is not the purpose of the decision. It also specifies the requirements of the decision-making process. This study assesses the situation by examining the frequency of end-of-life decisions by patients’ and physicians’ characteristics, and describes the decision-making processes. Methods We conducted a nationwide retrospective study of a random sample of adult patients who died in December 2009. Questionnaires were mailed to the physicians who certified/attended these deaths. Cases were weighted to adjust for response rate bias. Bivariate analyses and logistic regressions were performed for each decision. Results Of all deaths, 16.9% were sudden deaths with no information about end of life, 12.2% followed a decision to do everything possible to prolong life, and 47.7% followed at least one medical decision that may certainly or probably hasten death: withholding (14.6%) or withdrawal (4.2%) of treatments, intensified use of opioids and/or benzodiazepines (28.1%), use of medications to deliberately hasten death (i.e. not legally authorized) (0.8%), at the patient’s request (0.2%) or not (0.6%). All other variables held constant, cause of death, patient's age, doctor’s age and specialty, and place of death, influenced the frequencies of decisions. When a decision was made, 20% of the persons concerned were considered to be competent. The decision was discussed with the patient if competent in 40% (everything done) to 86% (intensification of alleviation of symptoms) of cases. Legal requirements regarding decision-making for incompetent patients were frequently not complied with. Conclusions This study shows that end-of-life medical decisions are common in France. Most are in compliance with the

  2. RanBPM Protein Acts as a Negative Regulator of BLT2 Receptor to Attenuate BLT2-mediated Cell Motility*

    BLT2, a low affinity receptor for leukotriene B4 (LTB4), is a member of the G protein-coupled receptor family and is involved in many signal transduction pathways associated with various cellular phenotypes, including chemotactic motility. However, the regulatory mechanism for BLT2 has not yet been demonstrated. To understand the regulatory mechanism of BLT2, we screened and identified the proteins that bind to BLT2. Using a yeast two-hybrid assay with the BLT2 C-terminal domain as bait, we found that RanBPM, a previously proposed scaffold protein, interacts with BLT2. We demonstrated the specific interaction between BLT2 and RanBPM by GST pulldown assay and co-immunoprecipitation assay. To elucidate the biological function of the RanBPM-BLT2 interaction, we evaluated the effects of RanBPM overexpression or knockdown. We found that BLT2-mediated motility was severely attenuated by RanBPM overexpression and that knockdown of endogenous RanBPM by shRNA strongly promoted BLT2-mediated motility, suggesting a negative regulatory function of RanBPM toward BLT2. Furthermore, we observed that the addition of BLT2 ligands caused the dissociation of BLT2 and RanBPM, thus releasing the negative regulatory effect of RanBPM. Finally, we propose that Akt-induced BLT2 phosphorylation at residue Thr355, which occurs after the addition of BLT2 ligands, is a potential mechanism by which BLT2 dissociates from RanBPM, resulting in stimulation of BLT2 signaling. Taken together, our results suggest that RanBPM acts as a negative regulator of BLT2 signaling to attenuate BLT2-mediated cell motility. PMID:23928309

  3. Capacity constraints, pricing and investment decisions in regulated firms with a special emphasis on the Argentine electricity transmission system

    NASA Astrophysics Data System (ADS)

    Torres Gomez, Clemencia

    Restructuring the electricity sector has fostered competition in generation and distribution but has reinforced the need for better regulation to ensure efficiency of transmission networks. This dissertation assesses the impact of the Argentinean reforms in electricity on transmission efficiency. It then goes beyond the Argentinean case and analyzes some regulatory issues affecting transmission. Chapter 2 shows that the Argentinean reforms increased reliability and brought prices closer to costs. However, regulatory fine-tuning is required to ensure sustainability. Chapter 3 examines the impact of unbundling on the construction of the transmission link to the Yacyreta generation complex. A long-term commercial contract in an unbundled industry allowed competition to reduce investment cost and facilitated better monitoring by outsiders. Chapter 4 analyzes investment procedures in the context of the proposal to build a fourth line in the Comahue corridor. While procedures are mostly coherent, some rules appear to distort incentives to expand. The narrow definition of beneficiaries limits the number of participants in the decision-making. Grid users' limited accountability reduces incentives to pay for expansion. Long term contracts could increase the cost of the constraints for the party with the obligation to deliver. Chapter 5 analyzes incentives to promote grid expansion under uncertain demand using a single period-single generator model. The monopolist underinvests in comparison to an unconstrained system to reduce the likelihood of having to pay for unutilized capacity, under lower than expected demand. Optimal transmission capacity is monotonically decreasing in the cost of capital, and weakly increasing in the probability of experiencing high demand. Two possible equilibrium values for grid capacity are identified, associated with the rationing prices for either low or high demand. Chapter 6 analyzes the Laffont/Tirole model of monopoly regulation under

    The recent school reform movement of the 1980s and 1990s has been characterized by school-based management (SBM) initiatives and participatory decision-making arrangements. While much has been written about the need for teacher, parental and community involvement in school decision-making, the role of the student in these experiments has remained…

    Background: In England and Wales, the "Mental Capacity Act 2005" (MCA) provides a new legal framework to regulate substitute decision-making relating to the welfare of adults who lack the capacity to make one or more autonomous decisions about their care and support. Any substitute decision made on behalf of an adult lacking capacity must be in…

    Air Products is designing, building, and operating a ceramic membrane fabrication facility (the “CerFab”) to enable production of membrane modules to supply a conceptual 2000 ton per day (TPD) ITM Oxygen facility (the “ITM Oxygen Development Facility”). Air Products is executing this project under the American Recovery and Reinvestment Act (ARRA) with the objective to accelerate the adoption of ITM Oxygen technology to help meet the country’s goals for deploying clean power plants. The objective of this Topical Report is to address the requirements of Decision Point 1, which pertains to the Site Selection for the CerFab. Air Products with subcontractor Ceramatec, Inc., has determined a ceramic membrane module manufacturing process and the building and site requirements of the process consistent with the manufacturing objectives of the ITM Oxygen development program and this ARRA project. Based on cost estimates for new construction and refurbishments of existing sites, Air Products chose to consider only existing buildings rather than new construction. The Salt Lake City, Utah, region was selected as the preferred location for the CerFab to enable Ceramatec, Inc., to support the Phase V project and on-going Phase III development activities. Twenty available properties were screened in this region, from which one property emerged clearly as the most suitable property to house the CerFab. The site meets the requirements of the CerFab in terms of floor space, power and other utilities, and building structural features. The site also meets criteria for ease of obtaining the requirement environmental permits, and is within the project cost allocation for the building site. Moreover, the site formerly housed a manufacturing company that ceased operations in 2010 as a result of the economic recession of 2008-9; the region of the site has experienced more than a doubling of the unemployment rate since 2007. Restarting a manufacturing operation in the same

  8. Transcription Factors SOD7/NGAL2 and DPA4/NGAL3 Act Redundantly to Regulate Seed Size by Directly Repressing KLU Expression in Arabidopsis thaliana

    PubMed Central

    Zhang, Yueying; Du, Liang; Xu, Ran; Cui, Rongfeng; Hao, Jianjun; Sun, Caixia; Li, Yunhai

    2015-01-01

    Although seed size is one of the most important agronomic traits in plants, the genetic and molecular mechanisms that set the final size of seeds are largely unknown. We previously identified the ubiquitin receptor DA1 as a negative regulator of seed size, and the Arabidopsis thaliana da1-1 mutant produces larger seeds than the wild type. Here, we describe a B3 domain transcriptional repressor NGATHA-like protein (NGAL2), encoded by the suppressor of da1-1 (SOD7), which acts maternally to regulate seed size by restricting cell proliferation in the integuments of ovules and developing seeds. Overexpression of SOD7 significantly decreases seed size of wild-type plants, while the simultaneous disruption of SOD7 and its closest homolog DEVELOPMENT-RELATED PcG TARGET IN THE APEX4 (DPA4/NGAL3) increases seed size. Genetic analyses indicate that SOD7 and DPA4 act in a common pathway with the seed size regulator KLU to regulate seed growth, but do so independently of DA1. Further results show that SOD7 directly binds to the promoter of KLUH (KLU) in vitro and in vivo and represses the expression of KLU. Therefore, our findings reveal the genetic and molecular mechanisms of SOD7, DPA4, and KLU in seed size regulation and suggest that they are promising targets for seed size improvement in crops.
