    Glycoprotein M6a is a neuronally expressed member of the proteolipid protein (PLP) family of tetraspans. In vitro studies suggested a potential role in neurite outgrowth and spine formation and previous investigations have identified M6a as a stress-regulated gene. To investigate whether the distribution of M6a correlates with neuronal structures susceptible to alterations in response to stress, we localized M6a expression in neurons of hippocampal formation, prefrontal cortex and cerebellum using in situ hybridization and confocal immunofluorescence microscopy. In situ hybridization confirmed that M6a is expressed in dentate gyrus and cerebellar granule neurons and in hippocampal and cortical pyramidal neurons. Confocal microscopy localized M6a immunoreactivity to distinct sites within axonal membranes, but not in dendrites or neuronal somata. Moreover, M6a colocalized with synaptic markers of glutamatergic, but not GABAergic nerve terminals. M6a expression in the adult brain is particularly strong in unmyelinated axonal fibers, i.e. cerebellar parallel and hippocampal mossy fibers. In contrast, myelinated axons exhibit only minimal M6a immunoreactivity localized exclusively to terminal regions. The present neuroanatomical data demonstrate that M6a is an axonal component of glutamatergic neurons and that it is localized to distinct sites of the axonal plasma membrane of pyramidal and granule cells.

    N6-methyladenosine (m6A) is an abundant internal modification in eukaryotic mRNA and plays regulatory roles in mRNA metabolism. However, methods to precisely locate the m6A modification remain limited. We present here a photo-crosslinking-assisted m6A sequencing strategy (PA-m6A-seq) to more accurately define sites with m6A modification. Using this strategy, we obtained a high-resolution map of m6A in a human transcriptome. The map resembles the general distribution pattern observed previously, and reveals new m6A sites at base resolution. Our results provide insight into the relationship between the methylation regions and the binding sites of RNA-binding proteins. PMID:25491922

    The identification of m(6)A demethylases and high-throughput sequencing analysis of methylated transcriptome corroborated m(6)A RNA epigenetic modification as a dynamic regulation process, and reignited its investigation in the past few years. Many basic concepts of cytogenetics have been revolutionized by the growing understanding of the fundamental role of m(6)A in RNA splicing, degradation and translation. In this review, we summarize typical features of methylated transcriptome in mammals, and highlight the 'writers', 'erasers' and 'readers' of m(6)A RNA modification. Moreover, we emphasize recent advances of biological functions of m(6)A and conceive the possible roles of m(6)A in the regulation of immune response and related diseases. PMID:27249342

    N(6)-Methyladenosine (m(6)A) is a widespread, reversible chemical modification of RNA molecules, implicated in many aspects of RNA metabolism. Little quantitative information exists as to either how many transcript copies of particular genes are m(6)A modified ('m(6)A levels') or the relationship of m(6)A modification(s) to alternative RNA isoforms. To deconvolute the m(6)A epitranscriptome, we developed m(6)A-level and isoform-characterization sequencing (m(6)A-LAIC-seq). We found that cells exhibit a broad range of nonstoichiometric m(6)A levels with cell-type specificity. At the level of isoform characterization, we discovered widespread differences in the use of tandem alternative polyadenylation (APA) sites by methylated and nonmethylated transcript isoforms of individual genes. Strikingly, there is a strong bias for methylated transcripts to be coupled with proximal APA sites, resulting in shortened 3' untranslated regions, while nonmethylated transcript isoforms tend to use distal APA sites. m(6)A-LAIC-seq yields a new perspective on transcriptome complexity and links APA usage to m(6)A modifications.

    Among myriads of distinct chemical modifications in RNAs, dynamic N6-methyladenosine (m(6)A) is one of the most prevalent modifications in eukaryotic mRNAs and non-coding RNAs. Similar to the critical role of chemical modifications in regulation of DNA and protein activities, RNA m(6)A modification is also observed to be involved in the regulation of diverse functions of RNAs including meiosis, fertility, development, cell reprogramming and circadian period. The RNA m(6)A modification is recognized by YTH domain containing family proteins comprising of YTHDC1-2 and YTHDF1-3. Here we focus on the nuclear m(6)A reader YTHDC1 and its regulatory role in alternative splicing and other RNA metabolic processes. PMID:27351695

    Leukemia cells are superior to hematopoietic cells with a normal differentiation potential in buffering cellular stresses, but the underlying mechanisms for this leukemic advantage are not fully understood. Using CRISPR/Cas9 deletion of the canonical autophagy-essential gene Atg7, we found that erythroleukemia K562 cells are armed with two sets of autophagic machinery. Alternative mitophagy is functional regardless of whether the canonical autophagic mechanism is intact or disrupted. Although canonical autophagy defects attenuated cell cycling, proliferation and differentiation potential, the leukemia cells retained their abilities for mitochondrial clearance and for maintaining low levels of reactive oxygen species (ROS) and apoptosis. Treatment with a specific inducer of mitophagy revealed that the canonical autophagy-defective erythroleukemia cells preserved a mitophagic response. Selective induction of mitophagy was associated with the upregulation and localization of RAB9A on the mitochondrial membrane in both wild-type and Atg7−/− leukemia cells. When the leukemia cells were treated with the alternative autophagy inhibitor brefeldin A or when the RAB9A was knocked down, this mitophagy was prohibited. This was accompanied by elevated ROS levels and apoptosis as well as reduced DNA damage repair. Therefore, the results suggest that erythroleukemia K562 cells possess an ATG7-independent alternative mitophagic mechanism that functions even when the canonical autophagic process is impaired, thereby maintaining the ability to respond to stresses such as excessive ROS and DNA damage.

    An extensive repertoire of modifications is known to underlie the versatile coding, structural and catalytic functions of RNA, but it remains largely uncharted territory. Although biochemical studies indicate that N(6)-methyladenosine (m(6)A) is the most prevalent internal modification in messenger RNA, an in-depth study of its distribution and functions has been impeded by a lack of robust analytical methods. Here we present the human and mouse m(6)A modification landscape in a transcriptome-wide manner, using a novel approach, m(6)A-seq, based on antibody-mediated capture and massively parallel sequencing. We identify over 12,000 m(6)A sites characterized by a typical consensus in the transcripts of more than 7,000 human genes. Sites preferentially appear in two distinct landmarks--around stop codons and within long internal exons--and are highly conserved between human and mouse. Although most sites are well preserved across normal and cancerous tissues and in response to various stimuli, a subset of stimulus-dependent, dynamically modulated sites is identified. Silencing the m(6)A methyltransferase significantly affects gene expression and alternative splicing patterns, resulting in modulation of the p53 (also known as TP53) signalling pathway and apoptosis. Our findings therefore suggest that RNA decoration by m(6)A has a fundamental role in regulation of gene expression. PMID:22575960

    Friend erythroleukemia cells were induced to differentiate by dimethyl sulfoxide (DMSO) and hexamethylene-bis-acetamide (HBMA) in order to investigate whether their lipid characteristics, common to other systems of transformed cells, revert to a normal differentiation pattern. DBA/2 mouse erythrocytes were examined as a model of terminal differentiation in erythroid lineage. Variants of erythroleukemia cells not inducible to erythroid differentiation by DMSO and HMBA were also used in this study, in order to test whether lipid modifications occurring in differentiated erythroleukemia cells were related to the differentiation process or caused by specific effects of the inducers. Friend erythroleukemia cells showed the same lipid characteristics as those found in other transformed cell types. That is, a high level of ether-linked lipids and low percentages of long chain polyunsaturated fatty acids along with an accumulation of monoenoic fatty acids in phospholipids. These lipid characteristics remained unchanged when erythroleukemia cells were induced to differentiation by either DMSO or HMBA. However, other lipid components of erythroleukemia cells, e.g., phosphatidylethanolamine and triglycerides, were affected by erythroid differentiation. There were also changes of some lipid components of erythroleukemia cells, such as cholesteryl esters, which were related to specific effects of the inducers. Both DMSO- and HMBA-resistant variants differed from the inducible erythroleukemia cells, mainly in their ether-linked phospholipid pattern. PMID:3475757

    The transcription factor PU.1 plays a central role in development and differentiation of hematopoietic cells. Evidence from PU.1 knockout mice indicates a pivotal role for PU.1 in myeloid lineage and B-lymphocyte development. In addition, PU.1 is a key player in the development of Friend erythroleukemia disease, which is characterized by proliferation and differentiation arrest of proerythrocytes. To study the role of PU.1 in erythroleukemia, we have used murine erythroleukemia cells, isolated from Friend virus-infected mice. Expression of PU.1 small interfering RNA in these cells led to significant inhibition of PU.1 levels. This was accompanied by inhibition of proliferation and restoration in the ability of the proerythroblastic cells to produce hemoglobin, i.e., reversion of the leukemic phenotype. The data suggest that overexpression of PU.1 gene is the immediate cause for maintaining the leukemic phenotype of the disease by retaining the self-renewal capacity of transformed erythroblastic cells and by blocking the terminal differentiation program towards erythrocytes.

    Recent discoveries of reversible N(6)-methyladenosine (m(6)A) methylation on messenger RNA (mRNA) and mapping of m(6)A methylomes in mammals and yeast have revealed potential regulatory functions of this RNA modification. In plants, defects in m(6)A methyltransferase cause an embryo-lethal phenotype, suggesting a critical role of m(6)A in plant development. Here, we profile m(6)A transcriptome-wide in two accessions of Arabidopsis thaliana and reveal that m(6)A is a highly conserved modification of mRNA in plants. Distinct from mammals, m(6)A in A. thaliana is enriched not only around the stop codon and within 3'-untranslated regions, but also around the start codon. Gene ontology analysis indicates that the unique distribution pattern of m(6)A in A. thaliana is associated with plant-specific pathways involving the chloroplast. We also discover a positive correlation between m(6)A deposition and mRNA abundance, suggesting a regulatory role of m(6)A in plant gene expression. PMID:25430002

    N6-methyladenosine (m6A) is the most abundant modified base in eukaryotic mRNA and has been linked to diverse effects on mRNA fate. Current m6A mapping approaches localize m6A residues to 100–200 nt-long regions of transcripts. The precise position of m6A in mRNAs cannot be identified on a transcriptome-wide level because there are no chemical methods to distinguish between m6A and adenosine. Here we show that anti-m6A antibodies can induce specific mutational signatures at m6A residues after ultraviolet light-induced antibody-RNA crosslinking and reverse transcription. We find these antibodies similarly induce mutational signatures at N6,2′-O-dimethyladenosine (m6Am), a nucleotide found at the first encoded position of certain mRNAs. Using these mutational signatures, we map m6A and m6Am at single-nucleotide resolution in human and mouse mRNA and identify snoRNAs as a novel class of m6A-containing ncRNAs. PMID:26121403

    Covalent addition of a methyl group to adenosine N(6) (m(6)A) is an evolutionarily conserved and common RNA modification that is thought to modulate several aspects of RNA metabolism. While the presence of multiple m(6)A editing sites on diverse viral RNAs was reported starting almost 40 years ago, how m(6)A editing affects virus replication has remained unclear. Here, we used photo-crosslinking-assisted m(6)A sequencing techniques to precisely map several m(6)A editing sites on the HIV-1 genome and report that they cluster in the HIV-1 3' untranslated region (3' UTR). Viral 3' UTR m(6)A sites or analogous cellular m(6)A sites strongly enhanced mRNA expression in cis by recruiting the cellular YTHDF m(6)A "reader" proteins. Reducing YTHDF expression inhibited, while YTHDF overexpression enhanced, HIV-1 protein and RNA expression, and virus replication in CD4+ T cells. These data identify m(6)A editing and the resultant recruitment of YTHDF proteins as major positive regulators of HIV-1 mRNA expression. PMID:27117054

Current mapping approaches localize m6A residues to transcript regions 100-200 nt long but cannot identify precise m6A positions on a transcriptome-wide level. Here we developed m6A individual-nucleotide-resolution cross-linking and immunoprecipitation (miCLIP) and used it to demonstrate that antibodies to m6A can induce specific mutational signatures at m6A residues after ultraviolet light-induced antibody-RNA cross-linking and reverse transcription. We found that these antibodies similarly induced mutational signatures at N(6),2'-O-dimethyladenosine (m6Am), a modification found at the first nucleotide of certain mRNAs. Using these signatures, we mapped m6A and m6Am at single-nucleotide resolution in human and mouse mRNA and identified small nucleolar RNAs (snoRNAs) as a new class of m6A-containing non-coding RNAs (ncRNAs).

    SUMMARY N6-methyl-adenosine (m6A) is the most abundant modification on messenger RNAs and is linked to human diseases, but its functions in mammalian development are poorly understood. Here we reveal the evolutionary conservation and function of m6A by mapping the m6A methylome in mouse and human embryonic stem cells. Thousands of messenger and long noncoding RNAs show conserved m6A modification, including transcripts encoding core pluripotency transcription factors. m6A is enriched over 3′ untranslated regions at defined sequence motifs, and marks unstable transcripts, including transcripts turned over upon differentiation. Genetic inactivation or depletion of mouse and human Mettl3, one of the m6A methylases, led to m6A erasure on select target genes, prolonged Nanog expression upon differentiation, and impaired ESC’s exit from self-renewal towards differentiation into several lineages in vitro and in vivo. Thus, m6A is a mark of transcriptome flexibility required for stem cells to differentiate to specific lineages. PMID:25456834

    2015-01-01

    The most abundant mRNA post-transcriptional modification is N6-methyladenosine (m6A) that has broad roles in RNA biology1-5. In mammalian cells, the asymmetric distribution of m6A along mRNAs leaves relatively less methylation in the 5′ untranslated region (5′UTR) compared to other regions6,7. However, whether and how 5′UTR methylation is regulated is poorly understood. Despite the crucial role of the 5′UTR in translation initiation, very little is known whether m6A modification influences mRNA translation. Here we show that in response to heat shock stress, m6A is preferentially deposited to the 5′UTR of newly transcribed mRNAs. We found that the dynamic 5′UTR methylation is a result of stress-induced nuclear localization of YTHDF2, a well characterized m6A “reader”. Upon heat shock stress, the nuclear YTHDF2 preserves 5′UTR methylation of stress-induced transcripts by limiting the m6A “eraser” FTO from demethylation. Remarkably, the increased 5′UTR methylation in the form of m6A promotes cap-independent translation initiation, providing a mechanism for selective mRNA translation under heat shock stress. Using Hsp70 mRNA as an example, we demonstrate that a single site m6A modification in the 5′UTR enables translation initiation independent of the 5′ end m7G cap. The elucidation of the dynamic feature of 5′UTR methylation and its critical role in cap-independent translation not only expands the breadth of physiological roles of m6A, but also uncovers a previously unappreciated translational control mechanism in heat shock response.

    Insertional mutagenesis of the spi-1 gene is associated with the emergence of malignant proerythroblasts during Friend virus-induced acute erythroleukemia. To determine the role of spi-1/PU.1 in the genesis of leukemia, we generated spi-1 transgenic mice. In one founder line the transgene was overexpressed as an unexpected-size transcript in various mouse tissues. Homozygous transgenic animals gave rise to live-born offspring, but 50% of the animals developed a multistep erythroleukemia within 1.5 to 6 months of birth whereas the remainder survived without evidence of disease. At the onset of the disease, mice became severely anemic. Their hematopoietic tissues were massively invaded with nontumorigenic proerythroblasts that express a high level of Spi-1 protein. These transgenic proerythroblasts are partially blocked in differentiation and strictly dependent on erythropoietin for their proliferation both in vivo and in vitro. A complete but transient regression of the disease was observed after erythrocyte transfusion, suggesting that the constitutive expression of spi-1 is related to the block of the differentiation of erythroid precursors. At relapse, erythropoietin-independent malignant proerythroblasts arose. Growth factor autonomy could be partially explained by the autocrine secretion of erythropoietin; however, other genetic events appear to be necessary to confer the full malignant phenotype. These results reveal that overexpression of spi-1 is essential for malignant erythropoiesis and does not alter other hematopoietic lineages. PMID:8628313

    2009-01-01

    It has been repeatedly shown that chronic stress changes dendrites, spines and modulates expression of synaptic molecules. These effects all may impair information transfer between neurons. The present study shows that chronic stress also regulates expression of M6a, a glycoprotein which is localised in axonal membranes. We have previously demonstrated that M6a is a component of glutamatergic axons. The present data reveal that it is the splice variant M6a-Ib, not M6a-Ia, which is strongly expressed in the brain. Chronic stress in male rats (3 weeks daily restraint) has regional effects: quantitative in situ hybridization demonstrated that M6a-Ib mRNA in dentate gyrus granule neurons and in CA3 pyramidal neurons is downregulated, whereas M6a-Ib mRNA in the medial prefrontal cortex is upregulated by chronic stress. This is the first study showing that expression of an axonal membrane molecule is differentially affected by stress in a region-dependent manner. Therefore, one may speculate that diminished expression of the glycoprotein in the hippocampus leads to altered output in the corresponding cortical projection areas. Enhanced M6a-Ib expression in the medial prefrontal cortex (in areas prelimbic and infralimbic cortex) might be interpreted as a compensatory mechanism in response to changes in axonal projections from the hippocampus. Our findings provide evidence that in addition to alterations in dendrites and spines chronic stress also changes the integrity of axons and may thus impair information transfer even between distant brain regions.

    The fungistatic antibiotics trichostatins (TS) A and C were isolated from culture broth of Streptomyces platensis No. 145 and were found to be potent inducers of differentiation in murine erythroleukemia (Friend and RV133) cells at concentrations of 1.5 X 10(-8) M for TSA and 5 X 10(-7) M for TSC. Differentiation induced by TS was cooperatively enhanced by UV irradiation but not by treatment with dimethyl sulfoxide. This enhanced activity was completely inhibited by adding cycloheximide to the culture medium 2 h after exposure to TS, suggesting that TS are dimethyl sulfoxide-type inducers of erythroid differentiation. No inhibitory effect of TS was observed on macromolecular synthesis in cultured cells.

    Methylation of adenosines at the N(6) position (m(6)A) is a dynamic and abundant epitranscriptomic mark that regulates critical aspects of eukaryotic RNA metabolism in numerous biological processes. The RNA methyltransferases METTL3 and METTL14 are components of a multisubunit m(6)A writer complex whose enzymatic activity is substantially higher than the activities of METTL3 or METTL14 alone. The molecular mechanism underpinning this synergistic effect is poorly understood. Here we report the crystal structure of the catalytic core of the human m(6)A writer complex comprising METTL3 and METTL14. The structure reveals the heterodimeric architecture of the complex and donor substrate binding by METTL3. Structure-guided mutagenesis indicates that METTL3 is the catalytic subunit of the complex, whereas METTL14 has a degenerate active site and plays non-catalytic roles in maintaining complex integrity and substrate RNA binding. These studies illuminate the molecular mechanism and evolutionary history of eukaryotic m(6)A modification in post-transcriptional genome regulation. PMID:27627798

Therefore the development of drug-based methods for the selective inhibition of globin accumulation is required. In this study, we employed peptide nucleic acids (PNAs) to alter globin gene expression. The main conclusion of the present study was that PNAs designed to target adult murine β-globin mRNA inhibit hemoglobin accumulation and erythroid differentiation of murine erythroleukemia (MEL) cells with high efficiency and fair selectivity. No major effects were observed on cell proliferation. Our study supports the concept that PNAs may be used to target mRNAs that, similar to globin mRNAs, are expressed at very high levels in differentiating erythroid cells. Our data suggest that PNAs inhibit the excess production of globins involved in the pathophysiology of hemoglobinopathies. PMID:25405921

    Two human demethylases, the fat mass and obesity-associated (FTO) enzyme and ALKBH5, oxidatively demethylate abundant N(6)-methyladenosine (m(6)A) residues in mRNA. Achieving a method for selective inhibition of FTO over ALKBH5 remains a challenge, however. Here, we have identified meclofenamic acid (MA) as a highly selective inhibitor of FTO. MA is a non-steroidal, anti-inflammatory drug that mechanistic studies indicate competes with FTO binding for the m(6)A-containing nucleic acid. The structure of FTO/MA has revealed much about the inhibitory function of FTO. Our newfound understanding, revealed herein, of the part of the nucleotide recognition lid (NRL) in FTO, for example, has helped elucidate the principles behind the selectivity of FTO over ALKBH5. Treatment of HeLa cells with the ethyl ester form of MA (MA2) has led to elevated levels of m(6)A modification in mRNA. Our collective results highlight the development of functional probes of the FTO enzyme that will (i) enable future biological studies and (ii) pave the way for the rational design of potent and specific inhibitors of FTO for use in medicine.

    The regulatory role of N(6)-methyladenosine (m(6)A) and its nuclear binding protein YTHDC1 in pre-mRNA splicing remains an enigma. Here we show that YTHDC1 promotes exon inclusion in targeted mRNAs through recruiting pre-mRNA splicing factor SRSF3 (SRp20) while blocking SRSF10 (SRp38) mRNA binding. Transcriptome assay with PAR-CLIP-seq analysis revealed that YTHDC1-regulated exon-inclusion patterns were similar to those of SRSF3 but opposite of SRSF10. In vitro pull-down assay illustrated a competitive binding of SRSF3 and SRSF10 to YTHDC1. Moreover, YTHDC1 facilitates SRSF3 but represses SRSF10 in their nuclear speckle localization, RNA-binding affinity, and associated splicing events, dysregulation of which, as the result of YTHDC1 depletion, can be restored by reconstitution with wild-type, but not m(6)A-binding-defective, YTHDC1. Our findings provide the direct evidence that m(6)A reader YTHDC1 regulates mRNA splicing through recruiting and modulating pre-mRNA splicing factors for their access to the binding regions of targeted mRNAs.

    Murine erythroleukemia (MEL) cells are erythroid progenitors whose programs of erythroid differentiation has been interrupted by transformation with the Friend virus complex. As a result of the ability of certain chemicals such as dimethylsulfoxide (DMSO) to induce terminal erythroid differentiation, the cells have been used as a model for understanding the molecular basis of cellular differentiation. Recent work on MEL cells as well as other differentiating systems indicates that expression of cellular protooncogenes is implicated in chemically mediated differentiation. In MEL cells the expression of the c-myc protooncogene undergoes unusual biphasic changes following inducer treatment. Levels of c-myc mRNA decrease 10- to 20-fold between 1 and 2 hr and are then reexpressed between 12 and 24 hr. These changes occur as a result of complex transcriptional and posttranscriptional regulatory events. Recent DNA transfection experiments, in which MEL cells were transfected with myc expression vectors, indicate that both the early decrease in c-myc expression and its subsequent reexpression are important events in the differentiation pathway. The work on MEL cells, as well as on other models of differentiation, is directed at understanding the molecular basis of leukemogenic transformation and cellular differentiation. The ability of c-myc, as well as other protooncogenes, to influence both of these events indicates that cellular protooncogenes play a central role in their regulation. Images FIGURE 1. FIGURE 2.

    We adapted UV CLIP (cross-linking immunoprecipitation) to accurately locate tens of thousands of m(6)A residues in mammalian mRNA with single-nucleotide resolution. More than 70% of these residues are present in the 3'-most (last) exons, with a very sharp rise (sixfold) within 150-400 nucleotides of the start of the last exon. Two-thirds of last exon m(6)A and >40% of all m(6)A in mRNA are present in 3' untranslated regions (UTRs); contrary to earlier suggestions, there is no preference for location of m(6)A sites around stop codons. Moreover, m(6)A is significantly higher in noncoding last exons than in next-to-last exons harboring stop codons. We found that m(6)A density peaks early in the 3' UTR and that, among transcripts with alternative polyA (APA) usage in both the brain and the liver, brain transcripts preferentially use distal polyA sites, as reported, and also show higher proximal m(6)A density in the last exons. Furthermore, when we reduced m6A methylation by knocking down components of the methylase complex and then examined 661 transcripts with proximal m6A peaks in last exons, we identified a set of 111 transcripts with altered (approximately two-thirds increased proximal) APA use. Taken together, these observations suggest a role of m(6)A modification in regulating proximal alternative polyA choice. PMID:26404942

    Cholesterol is an essential constituent of all mammalian cell membranes and its availability is therefore a prerequisite for cellular growth and other functions. Several lines of evidence are now indicating an association between alterations of cholesterol homeostasis and cell cycle progression. However, the role of cholesterol in cell differentiation is still largely unknown. To begin to address this issue, in this study we examined changes in cholesterol metabolism and in the mRNA levels of proteins involved in cholesterol import and esterification (multi-drug resistance, MDR-3) and acylCoA: cholesterol acyltransferase (ACAT) and cholesterol export (caveolin-1) in Friend virus-induced erythroleukemia cells (MELC), in the absence or in the presence of the chemical inducer of differentiation, hexamethylene bisacetamide (HMBA). FBS-stimulated growth of MELC was accompanied by an immediate elevation of cholesterol synthesis and cholesterol esterification, and by an increase in the levels of MDR-3 and ACAT mRNAs. A decrease in caveolin-1 expression was also observed. However, when MELC were treated with HMBA, the inhibition of DNA synthesis caused by HMBA treatment, was associated with a decrease in cholesterol esterification and in ACAT and MDR-3 mRNA levels and an increase in caveolin-1 mRNA. Detection of cytoplasmic neutral lipids by staining MELC with oil red O, a dye able to evidence CE but not FC, revealed that HMBA-treatment also reduced growth-stimulated accumulation of cholesterol ester to approximately the same extent as the ACAT inhibitor, SaH. Overall, these results indicate for the first time a role of cholesterol esterification and of some related genes in differentiation of erythroid cells. PMID:22184540

    Neuronal remodeling is a fundamental process by which the brain responds to environmental influences, e.g., during stress. In the hippocampus, chronic stress causes retraction of dendrites in CA3 pyramidal neurons. We have recently identified the glycoprotein M6a as a stress-responsive gene in the hippocampal formation. This gene is down-regulated in the hippocampus of both socially and physically stressed animals, and this effect can be reversed by antidepressant treatment. In the present work, we analyzed the biological function of the M6a protein. Immunohistochemistry showed that the M6a protein is abundant in all hippocampal subregions, and subcellular analysis in primary hippocampal neurons revealed its presence in membrane protrusions (filopodia/spines). Transfection experiments revealed that M6a overexpression induces neurite formation and increases filopodia density in hippocampal neurons. M6a knockdown with small interference RNA methodology showed that M6a low-expressing neurons display decreased filopodia number and a lower density of synaptophysin clusters. Taken together, our findings indicate that M6a plays an important role in neurite/filopodium outgrowth and synapse formation. Therefore, reduced M6a expression might be responsible for the morphological alterations found in the hippocampus of chronically stressed animals. Potential mechanisms that might explain the biological effects of M6a are discussed. PMID:16286650

    The first step in the biogenesis of microRNAs is the processing of primary microRNAs (pri-miRNAs) by the microprocessor complex, composed of the RNA binding protein DGCR8 and the ribonuclease type III DROSHA1–4. This initial event requires the recognition of the junction between the stem and the flanking single-stranded RNA of the pri-miRNA hairpin by DGCR8 followed by recruitment of DROSHA, which cleaves the RNA duplex to yield the pre-miRNA product5. While the mechanisms underlying pri-miRNA processing have been elucidated, the mechanism by which DGCR8 recognizes and binds pri-miRNAs as opposed to other secondary structures present in transcripts is not understood. We find that methyltransferase like 3 (METTL3) methylates pri-miRNAs, marking them for recognition and processing by DGCR8. Consistent with this, METTL3 depletion reduced the binding of DGCR8 to pri-miRNAs and resulted in the global reduction of mature miRNAs and concomitant accumulation of unprocessed pri-miRNAs. In vitro processing reactions confirmed the sufficiency of the m6A mark in promoting pri-miRNA processing. Finally, gain-of-function experiments revealed that METTL3 is sufficient to enhance miRNA maturation in a global and non-cell-type specific manner. Our findings reveal that the m6A mark acts as a key post-transcriptional modification that promotes the initiation of miRNA biogenesis. PMID:25799998

    N(6)-methyl-adenosine (m(6)A) is one of the most common and abundant modifications on RNA molecules present in eukaryotes. However, the biological significance of m(6)A methylation remains largely unknown. Several independent lines of evidence suggest that the dynamic regulation of m(6)A may have a profound impact on gene expression regulation. The m(6)A modification is catalyzed by an unidentified methyltransferase complex containing at least one subunit methyltransferase like 3 (METTL3). m(6)A modification on messenger RNAs (mRNAs) mainly occurs in the exonic regions and 3'-untranslated region (3'-UTR) as revealed by high-throughput m(6)A-seq. One significant advance in m(6)A research is the recent discovery of the first two m(6)A RNA demethylases fat mass and obesity-associated (FTO) gene and ALKBH5, which catalyze m(6)A demethylation in an α-ketoglutarate (α-KG)- and Fe(2+)-dependent manner. Recent studies in model organisms demonstrate that METTL3, FTO and ALKBH5 play important roles in many biological processes, ranging from development and metabolism to fertility. Moreover, perturbation of activities of these enzymes leads to the disturbed expression of thousands of genes at the cellular level, implicating a regulatory role of m(6)A in RNA metabolism. Given the vital roles of DNA and histone methylations in epigenetic regulation of basic life processes in mammals, the dynamic and reversible chemical m(6)A modification on RNA may also serve as a novel epigenetic marker of profound biological significances.

    Acute erythroleukemia is an uncommon subtype of acute myeloid leukemia which has been considered to be a subtype of AML with a worse prognosis. Intensive chemotherapy is the first line of treatment. In recent years, the effect of kefir on some malignancies has been experimented. Kefir is a kind of beverage, which obtained by incubation of kefir grains with raw milk. Kefir grains are a symbiotic complex of different kinds of yeasts and bacteria, especially lactic acid bacteria which gather in a mostly carbohydrate matrix, named kefiran. We investigated the effect of kefir on acute erythroleukemia cell line (KG-1) and peripheral blood mononuclear cells (PBMCs). The cell line and PBMCs were treated with different doses of kefir and milk and incubated for three different times. We used Polymixin B to block the lipopolysaccharide and NaOH (1 mol/l) to neutralize the acidic media. Viability was detected by MTT assay. Apoptosis and necrosis were assessed by annexin-propidium iodide staining. Our results showed that kefir induced apoptosis and necrosis in KG-1 cell line. It was revealed that kefir decreased proliferation in erythroleukemia cell line. We did not observe a remarkable effect of kefir on PBMCs. Our study suggested that kefir may have potential to be an effective treatment for erythroleukemia. PMID:26708130

    N(6)-methyladenosine (m(6)A) is the most abundant internal modification of messenger RNA. While the presence of m(6)A on transcripts can impact nuclear RNA fates, a reader of this mark that mediates processing of nuclear transcripts has not been identified. We find that the RNA-binding protein HNRNPA2B1 binds m(6)A-bearing RNAs in vivo and in vitro and its biochemical footprint matches the m(6)A consensus motif. HNRNPA2B1 directly binds a set of nuclear transcripts and elicits similar alternative splicing effects as the m(6)A writer METTL3. Moreover, HNRNPA2B1 binds to m(6)A marks in a subset of primary miRNA transcripts, interacts with the microRNA Microprocessor complex protein DGCR8, and promotes primary miRNA processing. Also, HNRNPA2B1 loss and METTL3 depletion cause similar processing defects for these pri-miRNA precursors. We propose HNRNPA2B1 to be a nuclear reader of the m(6)A mark and to mediate, in part, this mark's effects on primary microRNA processing and alternative splicing. PAPERCLIP. PMID:26321680

    Methylation at the N6 position of adenosine (m(6)A) is the most abundant RNA modification within protein-coding and long noncoding RNAs in eukaryotes and is a reversible process with important biological functions. YT521-B homology domain family (YTHDF) proteins are the readers of m(6)A, the binding of which results in the alteration of the translation efficiency and stability of m(6)A-containing RNAs. However, the mechanism by which YTHDF proteins cause the degradation of m(6)A-containing RNAs is poorly understood. Here we report that m(6)A-containing RNAs exhibit accelerated deadenylation that is mediated by the CCR4-NOT deadenylase complex. We further show that YTHDF2 recruits the CCR4-NOT complex through a direct interaction between the YTHDF2 N-terminal region and the SH domain of the CNOT1 subunit, and that this recruitment is essential for the deadenylation of m(6)A-containing RNAs by CAF1 and CCR4. Therefore, we have uncovered the mechanism of YTHDF2-mediated degradation of m(6)A-containing RNAs in mammalian cells. PMID:27558897

    SUMMARY N6-methyladenosine (m6A) is the most abundant internal modification of messenger RNA. While the presence of m6A on transcripts can impact alternative splicing, a nuclear reader of this mark that mediates the processing of nuclear transcripts has not been identified. We find that the RNA-binding HNRNPA2B1 protein binds m6A-bearing RNAs in vivo and in vitro and its biochemical footprint matches the m6A consensus motif. HNRNPA2B1 directly binds a set of nuclear transcripts and modulates their alternative splicing in a similar manner as the m6A ‘writer’ METTL3. Moreover, HNRNPA2B1 binds to m6A marks in a subset of primary-miRNA transcripts, interacts with the microRNA Microprocessor complex protein DGCR8, and promotes primary miRNA processing—phenocopying the effect of METTL3 depletion on the processing of these precursor transcripts. We propose HNRNPA2B1 to be a nuclear reader of the m6A mark and to mediate, in part, this mark’s effects on primary microRNA processing and alternative splicing. PMID:26321680

    N (6)-methyladenosine (m(6)A) is the most abundant and reversible internal modification ubiquitously occurring in eukaryotic mRNA, albeit the significant biological roles of m(6)A methylation have remained largely unclear. The well-known DNA and histone methylations play crucial roles in epigenetic modification of biologic processes in eukaryotes. Analogously, the dynamic and reversible m(6)A RNA modification, which is installed by methyltransferase (METTL3, METTL14, and WTAP), reversed by demethylases (FTO, ALKBH5) and mediated by m(6)A-binding proteins (YTHDF1-3, YTHDC1), may also have a profound impact on gene expression regulation. Recent discoveries of the distributions, functions, and mechanisms of m(6)A modification suggest that this methylation functionally modulates the eukaryotic transcriptome to influence mRNA transcription, splicing, nuclear export, localization, translation, and stability. This reversible mRNA methylation shed light on a new dimension of post-transcriptional regulation of gene expression at the RNA level. m(6)A methylation also plays significant and broad roles in various physiological processes, such as development, fertility, carcinogenesis, stemness, early mortality, meiosis and circadian cycle, and links to obesity, cancer, and other human diseases. This review mainly describes the current knowledge of m(6)A and perspectives on future investigations. PMID:27179969

    Epigenetic and epitranscriptomic networks have important functions in maintaining the pluripotency of embryonic stem cells (ESCs) and somatic cell reprogramming. However, the mechanisms integrating the actions of these distinct networks are only partially understood. Here we show that the chromatin-associated zinc finger protein 217 (ZFP217) coordinates epigenetic and epitranscriptomic regulation. ZFP217 interacts with several epigenetic regulators, activates the transcription of key pluripotency genes, and modulates N6-methyladenosine (m(6)A) deposition on their transcripts by sequestering the enzyme m(6)A methyltransferase-like 3 (METTL3). Consistently, Zfp217 depletion compromises ESC self-renewal and somatic cell reprogramming, globally increases m(6)A RNA levels, and enhances m(6)A modification of the Nanog, Sox2, Klf4, and c-Myc mRNAs, promoting their degradation. ZFP217 binds its own target gene mRNAs, which are also METTL3 associated, and is enriched at promoters of m(6)A-modified transcripts. Collectively, these findings shed light on how a transcription factor can tightly couple gene transcription to m(6)A RNA modification to ensure ESC identity. PMID:26526723

    N6-methyladenosine (m6A) residues are present as internal base modifications in most higher eucaryotic mRNAs; however, the biological function of this modification is not known. We describe a method for localizing and quantitating m6A within a large RNA molecule, the genomic RNA of Rous sarcoma virus. Specific fragments of 32P-labeled Rous sarcoma virus RNA were isolated by hybridization with complementary DNA restriction fragments spanning nucleotides 6185 to 8050. RNA was digested with RNase and finger-printed, and individual oligonucleotides were analyzed for the presence of m6A by paper electrophoresis and thin-layer chromatography. With this technique, seven sites of methylation in this region of the Rous sarcoma virus genome were localized at nucleotides 6394, 6447, 6507, 6718, 7414, 7424, and 8014. Further, m6A was observed at two additional sites whose nucleotide assignments remain ambiguous. A clustering of two or more m6A residues was seen at three positions within the RNA analyzed. Modification at certain sites was found to be heterogeneous, in that different molecules of RNA appeared to be methylated differently. Previous studies have determined that methylation occurs only in the sequences Gm6AC and Am6AC. We observed a high frequency of methylation at PuGm6ACU sequences. The possible involvement of m6A in RNA splicing events is discussed. PMID:3016525

    Ferritin has gained significant attention as a potential reporter gene for in vivo imaging by magnetic resonance imaging (MRI). However, due to the ferritin ferrihydrite core, the relaxivity and sensitivity for detection of native ferritin is relatively low. We report here on a novel chimeric magneto-ferritin reporter gene – ferritin-M6A – in which the magnetite binding peptide from the magnetotactic bacteria magnetosome-associated Mms6 protein was fused to the C-terminal of murine h-ferritin. Biophysical experiments showed that purified ferritin-M6A assembled into a stable protein cage with the M6A protruding into the cage core, enabling magnetite biomineralisation. Ferritin-M6A-expressing C6-glioma cells showed enhanced (per iron) r2 relaxivity. MRI in vivo studies of ferritin-M6A-expressing tumour xenografts showed enhanced R2 relaxation rate in the central hypoxic region of the tumours.

    Ferritin has gained significant attention as a potential reporter gene for in vivo imaging by magnetic resonance imaging (MRI). However, due to the ferritin ferrihydrite core, the relaxivity and sensitivity for detection of native ferritin is relatively low. We report here on a novel chimeric magneto-ferritin reporter gene - ferritin-M6A - in which the magnetite binding peptide from the magnetotactic bacteria magnetosome-associated Mms6 protein was fused to the C-terminal of murine h-ferritin. Biophysical experiments showed that purified ferritin-M6A assembled into a stable protein cage with the M6A protruding into the cage core, enabling magnetite biomineralisation. Ferritin-M6A-expressing C6-glioma cells showed enhanced (per iron) r2 relaxivity. MRI in vivo studies of ferritin-M6A-expressing tumour xenografts showed enhanced R2 relaxation rate in the central hypoxic region of the tumours. Such enhanced relaxivity would increase the sensitivity of ferritin as a reporter gene for non-invasive in vivo MRI-monitoring of cell delivery and differentiation in cellular or gene-based therapies.

    N(6)-methyladenosine (m(6)A) is a prevalent RNA methylation modification involved in the regulation of degradation, subcellular localization, splicing and local conformation changes of RNA transcripts. High-throughput experiments have demonstrated that only a small fraction of the m(6)A consensus motifs in mammalian transcriptomes are modified. Therefore, accurate identification of RNA m(6)A sites becomes emergently important. For the above purpose, here a computational predictor of mammalian m(6)A site named SRAMP is established. To depict the sequence context around m(6)A sites, SRAMP combines three random forest classifiers that exploit the positional nucleotide sequence pattern, the K-nearest neighbor information and the position-independent nucleotide pair spectrum features, respectively. SRAMP uses either genomic sequences or cDNA sequences as its input. With either kind of input sequence, SRAMP achieves competitive performance in both cross-validation tests and rigorous independent benchmarking tests. Analyses of the informative features and overrepresented rules extracted from the random forest classifiers demonstrate that nucleotide usage preferences at the distal positions, in addition to those at the proximal positions, contribute to the classification.

    N(6)-methyladenosine (m(6)A) is the most prevalent internal modification of eukaryotic mRNA. Very little is known of the function of m(6)A in the immune system or its role in host-pathogen interactions. Here, we investigate the topology, dynamics and bidirectional influences of the viral-host RNA methylomes during HIV-1 infection of human CD4 T cells. We show that viral infection triggers a massive increase in m(6)A in both host and viral mRNAs. In HIV-1 mRNA, we identified 14 methylation peaks in coding and noncoding regions, splicing junctions and splicing regulatory sequences. We also identified a set of 56 human gene transcripts that were uniquely methylated in HIV-1-infected T cells and were enriched for functions in viral gene expression. The functional relevance of m(6)A for viral replication was demonstrated by silencing of the m(6)A writer or the eraser enzymes, which decreased or increased HIV-1 replication, respectively. Furthermore, methylation of two conserved adenosines in the stem loop II region of HIV-1 Rev response element (RRE) RNA enhanced binding of HIV-1 Rev protein to the RRE in vivo and influenced nuclear export of RNA. Our results identify a new mechanism for the control of HIV-1 replication and its interaction with the host immune system. PMID:27572442

    Naïve and primed pluripotent states retain distinct molecular properties, yet limited knowledge exists on how their state transitions are regulated. Here, we identify Mettl3, an N(6)-methyladenosine (m(6)A) transferase, as a regulator for terminating murine naïve pluripotency. Mettl3 knockout preimplantation epiblasts and naïve embryonic stem cells are depleted for m(6)A in mRNAs, yet are viable. However, they fail to adequately terminate their naïve state and, subsequently, undergo aberrant and restricted lineage priming at the postimplantation stage, which leads to early embryonic lethality. m(6)A predominantly and directly reduces mRNA stability, including that of key naïve pluripotency-promoting transcripts. This study highlights a critical role for an mRNA epigenetic modification in vivo and identifies regulatory modules that functionally influence naïve and primed pluripotency in an opposing manner.

    Interest in mRNA methylation has exploded in recent years. The sudden interest in a 40 year old discovery was due in part to the finding of FTO's (Fat Mass Obesity) N6-methyl-adenosine (m6A) deaminase activity, thus suggesting a link between obesity-associated diseases and the presence of m6A in mRNA. Another catalyst of the sudden rise in mRNA methylation research was the release of mRNA methylomes for human, mouse and Saccharomyces cerevisiae. However, the molecular function, or functions of this mRNA 'epimark' remain to be discovered. There is supportive evidence that m6A could be a mark for mRNA degradation due to its binding to YTH domain proteins, and consequently being chaperoned to P bodies. Nonetheless, only a subpopulation of the methylome was found binding to YTHDF2 in HeLa cells.The model organism Saccharomyces cerevisiae, has only one YTH domain protein (Pho92, Mrb1), which targets PHO4 transcripts for degradation under phosphate starvation. However, mRNA methylation is only found under meiosis inducing conditions, and PHO4 transcripts are apparently non-methylated. In this paper we set out to investigate if m6A could function alternatively to being a degradation mark in S. cerevisiae; we also sought to test whether it can be induced under non-standard sporulation conditions. We find a positive association between the presence of m6A and message translatability. We also find m6A induction following prolonged rapamycin treatment. PMID:26186436

    N6-methyladenosine (m6A) is a common modification of mRNA with potential roles in fine-tuning the RNA life cycle. Here, we identify a dense network of proteins interacting with METTL3, a component of the methyltransferase complex, and show that three of them (WTAP, METTL14, and KIAA1429) are required for methylation. Monitoring m6A levels upon WTAP depletion allowed the definition of accurate and near single-nucleotide resolution methylation maps and their classification into WTAP-dependent and -independent sites. WTAP-dependent sites are located at internal positions in transcripts, topologically static across a variety of systems we surveyed, and inversely correlated with mRNA stability, consistent with a role in establishing "basal" degradation rates. WTAP-independent sites form at the first transcribed base as part of the cap structure and are present at thousands of sites, forming a previously unappreciated layer of transcriptome complexity. Our data shed light on the proteomic and transcriptional underpinnings of this RNA modification. PMID:24981863

    RlmJ catalyzes the m(6)A2030 methylation of 23S rRNA during ribosome biogenesis in Escherichia coli. Here, we present crystal structures of RlmJ in apo form, in complex with the cofactor S-adenosyl-methionine and in complex with S-adenosyl-homocysteine plus the substrate analogue adenosine monophosphate (AMP). RlmJ displays a variant of the Rossmann-like methyltransferase (MTase) fold with an inserted helical subdomain. Binding of cofactor and substrate induces a large shift of the N-terminal motif X tail to make it cover the cofactor binding site and trigger active-site changes in motifs IV and VIII. Adenosine monophosphate binds in a partly accommodated state with the target N6 atom 7 Å away from the sulphur of AdoHcy. The active site of RlmJ with motif IV sequence 164DPPY167 is more similar to DNA m(6)A MTases than to RNA m(6)2A MTases, and structural comparison suggests that RlmJ binds its substrate base similarly to DNA MTases T4Dam and M.TaqI. RlmJ methylates in vitro transcribed 23S rRNA, as well as a minimal substrate corresponding to helix 72, demonstrating independence of previous modifications and tertiary interactions in the RNA substrate. RlmJ displays specificity for adenosine, and mutagenesis experiments demonstrate the critical roles of residues Y4, H6, K18 and D164 in methyl transfer. PMID:23945937

    The major pathway of arachidonic acid metabolism in human platelets proceeds via a 12-lipoxygenase enzyme; however, the biological role of the product of this reaction, 12-hydro(pero)xyeicosatetraenoic acid [12-H(P)ETE], is unknown. Using a combination of the polymerase chain reaction and conventional screening procedures, we have isolated cDNA clones encoding the human platelet/human erythroleukemia (HEL) cell 12-lipoxygenase. From the deduced primary structure, human platelet/HEL 12-lipoxygenase would encode a Mr 75,000 protein consisting of 663 amino acids. The cDNA encoding the full-length protein (pCDNA-121x) under the control of the cytomegalovirus promoter was expressed in simian COS-M6 cells. Intact cells and lysed-cell supernatants were able to synthesize 12-H(P)ETE from arachidonic acid, whereas no 12-H(P)ETE synthesis was detected in mock-transfected cells. A single 2.4-kilobase mRNA was detected in erythroleukemia cells but not in several other tissues and cell lines evaluated by Northern blot analysis. Comparison of the human platelet/HEL 12-lipoxygenase sequence with that of porcine leukocyte 12-lipoxygenase and human reticulocyte 15-lipoxygenase revealed 65% amino acid identity to both enzymes. By contrast, the leukocyte 12-lipoxygenase is 86% identical to human reticulocyte 15-lipoxygenase. Sequence data and previously demonstrated immunochemical and biochemical evidence support the existence of distinct 12-lipoxygenase isoforms. The availability of cDNA probes for human platelet/HEL cell 12-lipoxygenase should facilitate elucidation of the biological role of this pathway. Images PMID:2377602

    Methylation at the N6 position of adenosine (m6A) is the most abundant RNA modification within protein-coding and long noncoding RNAs in eukaryotes and is a reversible process with important biological functions. YT521-B homology domain family (YTHDF) proteins are the readers of m6A, the binding of which results in the alteration of the translation efficiency and stability of m6A-containing RNAs. However, the mechanism by which YTHDF proteins cause the degradation of m6A-containing RNAs is poorly understood. Here we report that m6A-containing RNAs exhibit accelerated deadenylation that is mediated by the CCR4–NOT deadenylase complex. We further show that YTHDF2 recruits the CCR4–NOT complex through a direct interaction between the YTHDF2 N-terminal region and the SH domain of the CNOT1 subunit, and that this recruitment is essential for the deadenylation of m6A-containing RNAs by CAF1 and CCR4. Therefore, we have uncovered the mechanism of YTHDF2-mediated degradation of m6A-containing RNAs in mammalian cells. PMID:27558897

    N(6)-methyladenosine (m(6)A) is the most common reversible internal modification in mammalian RNA. Changes in m(6)A levels have been implicated in a variety of cellular processes, including nuclear RNA export, control of protein translation, and protein splicing, and they have been linked to obesity, cancer, and other human diseases. METTL3 and METTL14 are N(6)-adenosine methyltransferases that work more efficiently in a stable METTL3-METTL14 heterodimer complex (METTL3-14). ALKBH5 is an m(6)A-RNA demethylase that belongs to the AlkB family of dioxygenases. We report the development of radioactivity-based assays for kinetic characterization of m(6)A-RNA modifications by METTL3-14 complex and ALKBH5 and provide optimal assay conditions suitable for screening for ligands in a 384-well format with Z' factors of 0.78 and 0.77, respectively.

    4-Hydroxy-trans-2-nonenal (HNE) is one of the most abundant and toxic lipid aldehydes formed during lipid peroxidation by reactive oxygen species. We have investigated the genotoxic effects of HNE and its regulation by cellular glutathione (GSH) levels in human erythroleukemia (K562) cells. Incubation of K562 cells with HNE (5-10 {mu}M) significantly elicited a 3- to 5-fold increased DNA damage in a time- and dose-dependent manner as measured by comet assay. Depletion of GSH in cells by L-buthionine-[S,R]-sulfoximine (BSO) significantly increased HNE-induced DNA damage, whereas supplementation of GSH by incubating the cells with GSH-ethyl ester significantly decreased HNE-induced genotoxicity. Further, overexpression of mGSTA4-4, a HNE-detoxifying GST isozyme, significantly prevented HNE-induced DNA damage in cells, and ablation of GSTA4-4 and aldose reductase with respective siRNAs further augmented HNE-induced DNA damage. These results suggest that the genotoxicity of HNE is highly dependent on cellular GSH/GST/AR levels and favorable modulation of the aldehyde detoxification system may help in controlling the oxidative stress-induced complications.

    Highlights: Black-Right-Pointing-Pointer UT7 erythroleukemia cells are known to be refractory to differentiate. Black-Right-Pointing-Pointer Brief JQ1 treatment initiates the first steps of erythroid differentiation program. Black-Right-Pointing-Pointer Engaged UT7 cells then maturate in the presence of erythropoietin. Black-Right-Pointing-Pointer Sustained JQ1 treatment inhibits both proliferation and erythroid differentiation. -- Abstract: Malignant transformation is a multistep process requiring oncogenic activation, promoting cellular proliferation, frequently coupled to inhibition of terminal differentiation. Consequently, forcing the reengagement of terminal differentiation of transformed cells coupled or not with an inhibition of their proliferation is a putative therapeutic approach to counteracting tumorigenicity. UT7 is a human leukemic cell line able to grow in the presence of IL3, GM-CSF and Epo. This cell line has been widely used to study Epo-R/Epo signaling pathways but is a poor model for erythroid differentiation. We used the BET bromodomain inhibition drug JQ1 to target gene expression, including that of c-Myc. We have shown that only 2 days of JQ1 treatment was required to transitory inhibit Epo-induced UT7 proliferation and to restore terminal erythroid differentiation. This study highlights the importance of a cellular erythroid cycle break mediated by c-Myc inhibition before initiation of the erythropoiesis program and describes a new model for BET bromodomain inhibitor drug application.

    Erythroleukemia is generally associated with a very poor response and survival to current available therapeutic agents. Cyclooxygenase-2 (COX-2) has been described to play a crucial role in the proliferation and differentiation of leukemia cells, this enzyme seems to play an important role in chemoresistance in different cancer types. Previously, we demonstrated that diosgenin, a plant steroid, induced apoptosis in HEL cells with concomitant COX-2 overexpression. In this study, we investigated the antiproliferative and apoptotic effects of cyclopamine and jervine, two steroidal alkaloids with similar structures, on HEL and TF1a human erythroleukemia cell lines and, for the first time, their effect on COX-2 expression. Cyclopamine, but not jervine, inhibited cell proliferation and induced apoptosis in these cells. Both compounds induced COX-2 overexpression which was responsible for apoptosis resistance. In jervine-treated cells, COX-2 overexpression was NF-κB dependent. Inhibition of NF-κB reduced COX-2 overexpression and induced apoptosis. In addition, cyclopamine induced apoptosis and COX-2 overexpression via PKC activation. Inhibition of the PKC pathway reduced both apoptosis and COX-2 overexpression in both cell lines. Furthermore, we demonstrated that the p38/COX-2 pathway was involved in resistance to cyclopamine-induced apoptosis since p38 inhibition reduced COX-2 overexpression and increased apoptosis in both cell lines. - Highlights: ► Cyclopamine alone but not jervine induces apoptosis in human erythroleukemia cells. ► Cyclopamine and jervine induce COX-2 overexpression. ► COX-2 overexpression is implicated in resistance to cyclopamine-induced apoptosis. ► Apoptotic potential of jervine is restrained by NF-κB pathway activation. ► PKC is involved in cyclopamine-induced apoptosis and COX-2 overexpression.

    The aim of this study was to describe and understand the relationship between cyclooxygenase-2 (COX-2) expression and apoptosis rate in erythroleukemia cells after apoptosis induction by Berberis libanotica (Bl) extract. To achieve this goal we used erythroleukemia cell lines expressing COX‑2 (HEL cell line) or not (K562 cell line). Moreover, we made use of COX‑2 cDNA to overexpress COX‑2 in K562 cells. In light of the reported chemopreventive and chemosensitive effects of natural products on various tumor cells and animal models, we postulated that our Bl extract may mediate their effects through apoptosis induction with suppression of cell survival pathways. Our study is the first report on the specific examination of intrinsic apoptosis and Akt/NF-κB/COX‑2 pathways in human erythroleukemia cells upon Bl extract exposure. Even if Bl extract induced apoptosis of three human erythroleukemia cell lines, a dominant effect of Bl extract treatment on K562 cells was observed resulting in activation of the late markers of apoptosis with caspase-3 activation, PARP cleavage and DNA fragmentation. Whereas, we showed that Bl extract reduced significantly expression of COX‑2 by a dose-dependent manner in HEL and K562 (COX‑2+) cells. Furthermore, in regard to our results, it is clear that the simultaneous inhibition of Akt and NF-κB signalling can significantly contribute to the anticancer effects of Bl extract in human erythroleukemia cells. We observed that the Bl extract is clearly more active than the berberine alone on the induction of DNA fragmentation in human erythro-leukemia cells. PMID:25997834

    Thiosemicarbazones are a wide group of organic derivatives whose biological activities are a function of the parent aldehyde or ketone and of the coordination metal type. Some thiosemicarbazones possess a broad spectrum of potentially useful chemotherapeutic properties (antitumor, antibacterial, antiviral, antimalarial). The present study reports the biological effects of pyridoxal thiosemicarbazone, H2L, and relative complexes with copper, [(Cu(HL)(OH2))2]++ and with cobalt, [Co(III)(L)(HL)] on the differentiation of Friend erythroleukemia cells (FLC). They are murine proerythroblasts chronically infected by a producing Friend leukemia virus complex; their exposure to dimethylsulfoxide (Me2SO) or other chemical agents induces these cells to terminal erythroid differentiation, therefore these cells represent a good model of differentiation in vitro. Here we describe induction differentiation experiment of pyridoxal thiosemicarbazone and relative complexes of copper and cobalt on FLC performed with concentrations of 50 ug/ml (ligand), 2 ug/ml (complexes). These have little effects on cell proliferation at doses used in these experiments. Higher doses have evident cytotoxic effects. The treatment with the copper complex induces a moderate differentiation of FLC and enhances effects on erythroid differentiation of Me2SO-induced FLC. On the contrary H2L and [Co(III)(L)(HL)] haven't inducing effects or enhancing effects on Me2SO-induced FLC hemopoietic differentiation. In conclusion, the present study shows that copper complexes of pyridoxal thiosemicarbazone exert action of inducing agent and are able to enhance Me2SO-induced FLC hemopoietic differentiation.

    There are a number of agents which, when added to cultures of murine erythroleukemia cells (MELC), markedly increase the probability of commitment to express the characteristics of terminal erythroid differentiation, including loss of proliferative capacity and increased accumulation of globin mRNA and hemoglobin. Some characteristics of inducer-mediated commitment of MELC to terminal erythroid differentiation were examined by determining the effects of dexamethasone (an inhibitor of inducer-mediated MELC differentiation) and of hemin (an inducer of globin mRNA accumulation). Previously, it was shown that exposure of MELC to hexamethylene-bisacetamide (HMBA) leads to commitment, detectable within 12 hr. MELC cultured with both HMBA and dexamethasone do not express commitment. MELC transferred from culture with HMBA and dexamethasone to cloning medium without these agents express commitment to terminal erythroid differentiation, indicating that MELC retain a "memory" for some early HMBA-mediated changes leading to commitment which occur even in the presence of the inhibitory steroid. The kinetics of commitment in experiments in which exposure to HMBA is interrupted, or dexamethasone is added to the culture in HMBA, suggest that there is a rate-limiting step early in the commitment process. The memory for this step persists for more than one cell cycle. Addition of hemin to cultures with HMBA and dexamethasone initiated accumulation of globin mRNA but does not reverse the steroid-mediated inhibition of terminal cell division (that is, the cells retain their proliferative capacity). Inducer-mediated MELC commitment is associated with accumulation of the chromatin protein IP25; dexamethasone does not inhibit this accumulation. Accumulation of IP25 may be inducer-related, but it is not sufficient to cause expression of terminal erythroid differentiation. Images PMID:6952199

    Epigenetic mechanisms have an important role in the pre- and peri-conceptional programming by maternal nutrition. Yet, whether or not RNA m6A methylation—an old epigenetic marker receiving increased attention recently—is involved remains an unknown question. In this study, mouse high-fat feeding prior to conception was shown to induce overweight and glucose intolerant dams, which then continued to be exposed to a high-fat diet during gestation and lactation. The dams on a standard diet throughout the whole experiment were used as a control. Results showed that maternal high-fat intake impaired postnatal growth in male offspring, indicated by decreased body weight and Lee’s index at 3, 8 and 15 weeks old, but the percentages of visceral fat and tibialis anterior relative to the whole body weights were significantly increased at eight weeks of age. The maternal high-fat exposure significantly increased mRNA N6-methyladenosine (m6A) levels in visceral fat at three weeks old, combined with downregulated Fat mass and obesity-associated gene (FTO) and upregulated Methyltransferase like 3 (METTL3) transcription, and these changes were reversed at eight weeks of age. In the tibialis anterior muscle, the maternal high-fat diet significantly enhanced m6A modifications at three weeks, and lowered m6A levels at 15 weeks of age. Accordingly, FTO transcription was significantly inhibited at three weeks and stimulated at 15 weeks of age, and METTL3 transcripts were significantly improved at three weeks. Interestingly, both FTO and METTL3 transcription was significantly elevated at eight weeks of age, and yet the m6A modifications remained unchanged. Our study showed that maternal high-fat intake could affect mRNA m6A modifications and its related genes in offspring in a tissue-specific and development-dependent way, and provided an interesting indication of the working of the m6A system during the transmission from maternal nutrition to subsequent generations.

    The dimethylsulfoxide (Me/sub 2/SO)-mediated induction of hemoglobin synthesis in Friend erythroleukemia cells is inhibited by the glucocorticoids hydrocortisone, dexamethasone, and fluocinolone acetonide; hydrocortisone, at concentrations of 10/sup -5/ to 10/sup -8/ M inhibits by 90-30% and fluocinolone acetonide at concentrations of 10/sup -8/ to 10/sup -11/ M shows a greater than 90% inhibition. At these concentrations the hormones have no effect on cell growth or viability. In this study it has been shown that there is a group of proteins, including the ..cap alpha..- and ..beta..-globins, whose regulation is associated with the induction of Friend erythroleukemia cell differentiation, and that the expression of these, in addition to ..cap alpha..- and ..beta..-globin, is affected by glucocorticoids. It is concluded that, although the translation of ..cap alpha..- and ..beta..-globin mRNA is a major site of inhibition by glucocorticoids, there is a detectable amount of ..cap alpha..- and ..beta..-globin mRNA translation which results in unequal amounts of globin synthesis and an overall more potent inhibition of hemoglobin formation.

    The consequences of herpes simplex virus type 1 infection on cellular macromolecules were investigated in Friend erythroleukemia cells. The patterns of protein synthesis, examined by polyacrylamide gel electrophoresis, demonstrated that by 4 h postinfection the synthesis of many host proteins, with the exception of histones, was inhibited. Examination of the steady-state level of histone H3 mRNA by molecular hybridization of total RNA to a cloned mouse histone H3 complementary DNA probe demonstrated that the ratio of histone H3 mRNA to total RNA remained unchanged for the first 4 h postinfection. In contrast, the steady-state levels of globin and actin mRNAs decreased progressively at early intervals postinfection. Studies on RNA synthesis in isolated nuclei demonstrated that the transcription of the histone H3 gene was inhibited to approximately the same extent as that of actin gene. It was concluded that the stabilization of preexisting histone H3 mRNA was responsible for the persistence of H3 mRNA and histone protein synthesis in herpes simplex virus type 1-infected Friend erythroleukemia cells. The possible mechanisms influencing the differential stability of host mRNAs during the course of productive infection with herpes simplex virus type 1 are discussed.

    Motivation: N6-methyl-adenosine (m6A) is the most prevalent mRNA methylation but precise prediction of its mRNA location is important for understanding its function. A recent sequencing technology, known as Methylated RNA Immunoprecipitation Sequencing technology (MeRIP-seq), has been developed for transcriptome-wide profiling of m6A. We previously developed a peak calling algorithm called exomePeak. However, exomePeak over-simplifies data characteristics and ignores the reads’ variances among replicates or reads dependency across a site region. To further improve the performance, new model is needed to address these important issues of MeRIP-seq data. Results: We propose a novel, graphical model-based peak calling method, MeTPeak, for transcriptome-wide detection of m6A sites from MeRIP-seq data. MeTPeak explicitly models read count of an m6A site and introduces a hierarchical layer of Beta variables to capture the variances and a Hidden Markov model to characterize the reads dependency across a site. In addition, we developed a constrained Newton’s method and designed a log-barrier function to compute analytically intractable, positively constrained Beta parameters. We applied our algorithm to simulated and real biological datasets and demonstrated significant improvement in detection performance and robustness over exomePeak. Prediction results on publicly available MeRIP-seq datasets are also validated and shown to be able to recapitulate the known patterns of m6A, further validating the improved performance of MeTPeak. Availability and implementation: The package ‘MeTPeak’ is implemented in R and C ++, and additional details are available at https://github.com/compgenomics/MeTPeak Contact: yufei.huang@utsa.edu or xdchoi@gmail.com Supplementary information: Supplementary data are available at Bioinformatics online.

    Thromboxane A2 (TxA2), a platelet aggregator and vasoconstrictor, has been implicated as a potential mediator of cardiovascular diseases. Abuse of androgenic steroids has been associated with thrombotic cardiovascular diseases. Human erythroleukemia (HEL) cells, a megakaryocyte-like cell line, express functional TxA2/prostaglandin H2 (PGH2) receptors with characteristics similar to those seen in platelets. This study characterized testosterone regulation of HEL cell TxA2/PGH2 receptors. TxA2/PGH2 receptor affinity (Kd) and density (Bmax) were determined via equilibrium binding experiments using the radiolabeled TxA2 mimetic (1S-[1 alpha,2 beta(5Z),3 alpha(1E,3R*),4 alpha])-7-(3-[3-hydroxy-4-(4'- iodophenoxy)-1-butenyl]-7-oxabicyclo[2.2.1]heptan-2-yl)-5-he ptenoic acid (125I-labeled BOP). Testosterone (200 nM) but not estradiol increased Bmax from 108 +/- 9 fmol/mg protein to 157 +/- 9 fmol/mg protein (n = 7 experiments; P < 0.01) without any significant change in Kd. Testosterone had no significant effect on alpha 2-adrenergic receptor density. The maximum increase in intracellular free calcium induced by the TxA2 agonists I-BOP or U-46619 was significantly (P < 0.005) greater in testosterone-treated cells compared with controls. Hydroxyflutamide (1 microM), an androgen-receptor antagonist, completely blocked the effect of testosterone (P < 0.01). Dihydrotestosterone, the active metabolite of testosterone, also increased Bmax in a concentration-dependent manner and was more potent than testosterone. The effect of testosterone to increase Bmax was significantly (P < 0.01) inhibited by coincubation with cycloheximide (0.1 microgram/ml) or actinomycin D (10 ng/ml). These results indicate that androgenic steroids regulate the expression of functional TxA2/PGH2 receptors in HEL cells. These findings may have relevance to cardiovascular disease. PMID:8279549

    The loss of alpha-globin gene transcriptional activity rarely occurs as an acquired abnormality during the evolution of myeloproliferative disease or preleukemia. To test whether the mutation responsible for the loss of alpha-globin gene expression (hemoglobin H disease) in these patients is linked with the alpha-globin genes on chromosome 16, we transferred chromosome 16 from preleukemic patients with acquired hemoglobin H disease to mouse erythroleukemia cells and measured the transcriptional activity of the human alpha-globin genes. After transfer to mouse erythroleukemia cells, the expression of human alpha-globin genes from the peripheral blood or marrow cells of preleukemic patients with acquired hemoglobin H disease was similar to that of human alpha-globin genes transferred to mouse erythroleukemia cells from normal donors. These data showed that factor(s) in the mouse erythroleukemia cell can genetically complement the alpha-globin gene defect in these preleukemia patients with acquired hemoglobin H disease and suggest that altered expression of a gene in trans to the alpha-globin gene may be responsible for the acquisition of hemoglobin H disease in these patients.

    Chemical landscape of natural RNA species is decorated with the large number of modified nucleosides. Some of those could easily be detected by reverse transcription, while others permit only high-performance liquid chromatography or mass-spectrometry detection. Presence of m(6)A nucleoside at a particular position of long RNA molecule is challenging to observe. Here we report an easy and high-throughput method for detection of m(6)A nucleosides in RNA based on high-resolution melting analysis. The method relies on the previous knowledge of the modified nucleoside position at a particular place of RNA and allows rapid screening for conditions or genes necessary for formation of that modification.

    Methyltransferases (MTases) from the Erm family catalyze S-adenosyl-L-methionine-dependent modification of a specific adenine residue in bacterial 23S rRNA, thereby conferring resistance to clinically important macrolide, lincosamide and streptogramin B antibiotics. Despite the available structural data and functional analyses on the level of the RNA substrate, still very little is known about the mechanism of rRNA:adenine-N(6) methylation. Only predictions regarding various aspects of this reaction have been made based on the analysis of the crystal structures of methyltransferase ErmC' (without the RNA) and their comparison with the crystallographic and biochemical data for better studied DNA:m(6)A MTases. To validate the structure-based predictions of presumably essential residues in the catalytic pocket of ErmC', we carried out the site-directed mutagenesis and studied the function of the mutants in vitro and in vivo. Our results indicate that the active site of rRNA:m(6)A MTases is much more tolerant to amino acid substitutions than the active site of DNA:m(6)A MTases. Only the Y104 residue implicated in stabilization of the target base was found to be indispensable. Remarkably, the N101 residue from the "catalytic" motif IV and two conserved residues that form the floor (F163) and one of the walls (N11) of the base-binding site are not essential for catalysis in ErmC'. This somewhat surprising result is discussed in the light of the available structural data and in the phylogenetic context of the Erm family. PMID:12946350

    N6-methyladenosine (m6A) is a common modification of mRNA, with potential roles in fine-tuning the RNA life-cycle. Here, we identify a dense network of proteins interacting with METTL3, a component of the methyltransferase complex, and show that three of them, WTAP, METTL14 and KIAA1429, are required for methylation. Monitoring m6A levels upon WTAP depletion allowed the definition of accurate and near single-nucleotide resolution methylation maps, and their classification into WTAP-dependent and independent sites. WTAP-dependent sites are located at internal positions in transcripts, are topologically static across a variety of systems we surveyed, and are inversely correlated with mRNA stability, consistent with a role in establishing ‘basal’ degradation rates. WTAP-independent sites form at the first transcribed base as part of the cap structure, and are present at thousands of sites, forming a previously unappreciated layer of transcriptome complexity. Our data sheds new light on proteomic and transcriptional underpinnings of this epitranscriptomic modification. PMID:24981863

    The mechanisms that regulate the expression of the H chain of the iron storage protein ferritin in Friend erythroleukemia cells (FLCs) after exposure to hemin (ferric protoporphyrin IX), protoporphyrin IX, and ferric ammonium citrate (FAC) have been investigated. Administration of hemin increases the steady-state level of ferritin mRNA about 10-fold and that of ferritin protein expression 20-fold. Experiments with the transcriptional inhibitor actinomycin D and transfection studies demonstrate that the increment in cytoplasmic mRNA content results from enhanced transcription of the ferritin H-chain gene and cannot be attributed to stabilization of preexisting mRNAs. In addition to transcriptional effects, translational regulation induces the recruitment of stored mRNAs into functional polyribosomes after hemin and FAC administration, resulting in a further increase in ferritin synthesis. Administration of protoporphyrin IX to FLCs produces divergent transcriptional and translational effects. It increases transcription but appears to suppress ferritin mRNA translation. FAC treatment increases the mRNA content slightly (about twofold), and the ferritin levels rise about fivefold over the control values. We conclude that in FLCs, hemin induces ferritin H-chain biosynthesis by multiple mechanisms: a transcriptional mechanism exerted also by protoporphyrin IX and a translational one, not displayed by protoporphyrin IX but shared with FAC.

    Platelets metabolize arachidonic acid to thromboxane A2, a potent platelet aggregator and vasoconstrictor compound. The first step of this transformation is catalyzed by prostaglandin (PG) G/H synthase, a target site for nonsteroidal antiinflammatory drugs. We have isolated the cDNA for both human platelet and human erythroleukemia cell PGG/H synthase using the polymerase chain reaction and conventional screening procedures. The cDNA encoding the full-length protein was expressed in COS-M6 cells. Microsomal fractions from transfected cells produced prostaglandin endoperoxide-derived products which were inhibited by indomethacin and aspirin. Mutagenesis of the serine residue at position 529, the putative aspirin acetylation site, to an asparagine reduced cyclooxygenase activity to barely detectable levels, an effect observed previously with the expressed sheep vesicular gland enzyme. Platelet-derived growth factor and phorbol ester differentially regulated the expression of PGG/H synthase mRNA levels in the megakaryocytic/platelet-like HEL cell line. The PGG/H synthase gene was assigned to chromosome 9 by analysis of a human--hamster somatic hybrid DNA panel. The availability of platelet PGG/H synthase cDNA should enhance our understanding of the important structure/function domains of this protein and its gene regulation. PMID:1907252

    Time lapse video photography was used to follow the movement of individual cells after in vitro treatment with Hg(II) acetate. Cellular changes of mercuric ions were characterized by their properties of causing reduced cellular mobility (10-50microM), and complete lack of cellular movement at higher concentrations (100-1000microM). Results show that after mercury treatment at subtoxic levels (1microM): (a) chromatin changes were the earliest signs of cytotoxicity, (b) two major parts in nuclear material of K562 erythroleukemia cells could be distinguished, highly condensed supercoiled and decondensed veil-like chromatin, (c) decondensed chromosomes were rejected as clustered puffs and (d) often the nuclear material was broken down to apoptotic bodies. Nuclear changes caused by Hg(II) acetate in the concentration range between 10 and 50microM were characterized by apoptosis seen as broken nuclei and apoptotic bodies. High concentration of Hg(2+) ions (100microM) initiated necrotic nuclear changes, with enlarged leaky or opened nuclei. PMID:19723577

    Exon 16 inclusion is a critical splicing event that triggers the production of a functional protein 4.1R in mature normal erythroblasts, and is obviated in PU.1-induced erythroleukemia cells. Exon 16 contains an exonic splicing silencer (ESS16) that interacts with hnRNP A/B in heterologous cell context. We here show that ESS16 promotes the recruitment of a protein complex containing hnRNP A1 and a 79-kDa protein in nuclear extracts from either proliferative erythroleukemia cells or cells induced to terminal differentiation. By using 2D gel fractionation and mass spectrometry, we unambiguously identified KSRP as the 79-kDa component interacting with ESS16. Furthermore, we show that KSRP slightly decreases in erythroleukemia cells induced to terminal erythroid differentiation. Yet, KSRP inducible knockdown, through stable transfection of small hairpin KSRP RNA, did not alter exon 16 splicing, suggesting that KSRP alone does not modulate the splicing event. Interestingly, absence of hnRNP A1 prevented KSRP from binding to ESS16. Reciprocally, KSRP interaction with ESS16 was recovered when hnRNP A1 expression is restored in hnRNP A1-null cells. Collectively, this study establishes that hnRNPA1 is part of a KSRP-containing RNP complex, and emphasizes that, aside from its function in AU-rich element-mediated mRNA decay and its role in microRNA biogenesis, KSRP associates with hnRNP A1 to bind an ESS. These findings further support the role of members of the KH-domain protein family in organizing large RNA-protein complex formation, rather than primarily in modulating specific splicing events.

    Cycloleucine, a competitive inhibitor of methionine transferase was used to generate in vivo partially methylated mRNA in SV40-infected BSC-1 cells. Cycloleucine at 0.5 mg/ml causes more than a 30% decrease in internal m6As of late SV40 mRNA with only minor effect on the dimethyladenosine of the 5' caps m7GpppmAm. After treatment with 2 and 5 mg/ml of cycloleucine, internal m6As were reduced by 10- and 100-fold, respectively. The inhibition of BSC-1 mRNA methylations paralleled that observed for late SV40 mRNAs. In cells exposed to 2 mg/ml cycloleucine production of late SV40 mRNA was inhibited by 80% whereas the amount of SV40 nuclear RNA was only slightly reduced. Size fractionation of SV40 nuclear RNA from cycloleucine-treated cells revealed a loss of SV40 19 S RNA with a corresponding increase of fragmented RNA sedimenting between 11 to 5 S, so that the total amount of SV40 RNA in the nucleus was almost unchanged. Analysis of viral transcription complexes from cells treated with cycloleucine indicated that SV40 transcription was not affected by cycloleucine. SV40-transformed cells, in contrast to BSC-1 cells, were able to process and transport undermethylated RNA. When transformed cells were treated with 2 mg/ml cycloleucine no changes in quantities or size of cytoplasmic and nuclear RNA were detected. The data argues for a role of internal m6A moieties in modulating the processing-linked transport of mRNA from the nucleus to the cytoplasm of nontransformed cells. Transformed cells may escape these controls due to structural alterations in their perinuclear regions. PMID:6318439

    The effects of AC field exposure on the viability and proliferation of mammalian cells under conditions appropriate for their dielectrophoretic manipulation and sorting were investigated using DS19 murine erythroleukemia cells as a model system. The frequency range 100 Hz-10 MHz and medium conductivities of 10 mS/m, 30 mS/m and 56 mS/m were studied for fields generated by applying signals of up to 7V peak to peak (p-p) to a parallel electrode array having equal electrode widths and gaps of 100 μm. Between 1 kHz and 10 MHz, cell viability after up to 40 min of field exposure was found to be above 95% and cells were able to proliferate. However, cell growth lag phase was extended with decreasing field frequency and with increasing voltage, medium conductivity and exposure duration. Modified growth behavior was not passed on to the next cell passage, indicating that field exposure did not cause permanent alterations in cell proliferation characteristics. Cell membrane potentials induced by field exposure were calculated and shown to be well below values typically associated with cell damage. Furthermore, medium treated by field exposure and then added to untreated cells produced the same modifications of growth as exposing cells directly, and these modifications occurred only when the electrode polarization voltage exceeded a threshold of ~0.4 V p-p. These findings suggested that electrochemical products generated during field exposure were responsible for the changes in cell growth. Finally, it was found that hydrogen peroxide was produced when sugar-containing media were exposed to fields and that normal cell growth could be restored by addition of catalase to the medium, whether or not field exposure occurred in the presence of cells. These results show that AC fields typically used for dielectrophoretic manipulation and sorting of cells do not damage DS19 cells and that cell alterations arising from electrochemical effects can be completely mitigated.

    The cyclic pyrimidine nucleotides cCMP and cUMP have been recently identified in numerous mammalian cell lines, in primary cells and in intact organs, but very little is still known about their biological function. A recent study of our group revealed that the membrane-permeable cCMP analog cCMP-acetoxymethylester (cCMP-AM) induces apoptosis in mouse lymphoma cells independent of protein kinase A via an intrinsic and mitochondria-dependent pathway. In our present study, we examined the effects of various cNMP-AMs in human tumor cell lines. In HEL cells, a human erythroleukemia cell line, cCMP-AM effectively reduced the number of viable cells, effectively induced apoptosis by altering the mitochondrial membrane potential and thereby caused changes in the cell cycle. cCMP itself was biologically inactive, indicating that membrane penetration is required to trigger intracellular effects. cCMP-AM did not induce apoptosis in K-562 cells, a human chronic myelogenous leukemia cell line, due to rapid export via multidrug resistance-associated proteins. The biological effects of cCMP-AM differed from those of other cNMP-AMs. In conclusion, cCMP effectively induces apoptosis in HEL cells, cCMP export prevents apoptosis of K-562 cells and cNMPs differentially regulate various aspects of apoptosis, cell growth and mitochondrial function. In a broader perspective, our data support the concept of distinct second messenger roles of cAMP, cGMP, cCMP and cUMP. PMID:27157412

    Acidovorax citrulli is a seedborne bacterium that causes bacterial fruit blotch of cucurbit plants including watermelon and melon. A. citrulli strains can be divided into two major groups based on DNA fingerprint analyses and biochemical properties. Group I strains have been generally isolated from non-watermelon cucurbits, while group II strains are closely associated with watermelon. In the present study, we report the genome sequence of M6, a group I model A. citrulli strain, isolated from melon. We used comparative genome analysis to investigate differences between the genome of strain M6 and the genome of the group II model strain AAC00-1. The draft genome sequence of A. citrulli M6 harbors 139 contigs, with an overall approximate size of 4.85 Mb. The genome of M6 is ∼500 Kb shorter than that of strain AAC00-1. Comparative analysis revealed that this size difference is mainly explained by eight fragments, ranging from ∼35–120 Kb and distributed throughout the AAC00-1 genome, which are absent in the M6 genome. In agreement with this finding, while AAC00-1 was found to possess 532 open reading frames (ORFs) that are absent in strain M6, only 123 ORFs in M6 were absent in AAC00-1. Most of these M6 ORFs are hypothetical proteins and most of them were also detected in two group I strains that were recently sequenced, tw6 and pslb65. Further analyses by PCR assays and coverage analyses with other A. citrulli strains support the notion that some of these fragments or significant portions of them are discriminative between groups I and II strains of A. citrulli. Moreover, GC content, effective number of codon values and cluster of orthologs’ analyses indicate that these fragments were introduced into group II strains by horizontal gene transfer events. Our study reports the genome sequence of a model group I strain of A. citrulli, one of the most important pathogens of cucurbits.

    GATA-1 and PU.1 are two important hematopoietic transcription factors that mutually inhibit each other in progenitor cells to guide entrance into the erythroid or myeloid lineage, respectively. PU.1 controls its own expression during myelopoiesis by binding to the distal URE enhancer, whose deletion leads to acute myeloid leukemia (AML). We herein present evidence that GATA-1 binds to the PU.1 gene and inhibits its expression in human AML-erythroleukemias (EL). Furthermore, GATA-1 together with DNA methyl Transferase I (DNMT1) mediate repression of the PU.1 gene through the URE. Repression of the PU.1 gene involves both DNA methylation at the URE and its histone H3 lysine-K9 methylation and deacetylation as well as the H3K27 methylation at additional DNA elements and the promoter. The GATA-1-mediated inhibition of PU.1 gene transcription in human AML-EL mediated through the URE represents important mechanism that contributes to PU.1 downregulation and leukemogenesis that is sensitive to DNA demethylation therapy.

    An assay for endoplasmic reticulum (ER)-through-Golgi transport has been developed in streptolysin O-permeabilized murine erythroleukemia (MEL) cells. The reporter proteins are metabolically labeled native murine glycophorins, which display a distinctive shift in electrophoretic mobility after acquisition of O-linked oligosaccharides. The O-linked sugars are acquired at a site distal to a brefeldin A block, presumably in a cis Golgi compartment, and sialylation occurs in middle and/or trans Golgi compartments. In permeabilized cells supplemented with cytosolic proteins and an ATP-generating system, 20-50% of the radiolabeled precursor glycophorins can be converted to the mature, sialylated form. This maturation process is ATP- and cytosol-dependent and is blocked by guanosine 5'-[gamma-thio]triphosphate (GTP[gamma S]). Electron microscopy of permeabilized MEL cells shows retention of ER elements, stacked Golgi cisternae, free polysomes, and other subcellular components. In the presence of GTP[gamma S], dilated vesicles accumulate around the Golgi stacks. Antisera to the carboxyl terminus of the Golgi resident alpha subunit of Gi3 inhibit maturation of glycophorin. To our knowledge, a transport assay utilizing O-glycosylation of an endogenous protein as a monitor of ER-through-Golgi traffic in permeabilized cells has not been reported previously. Furthermore, the data provide evidence for heterotrimeric GTP-binding protein involvement in Golgi function. Images Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 PMID:8446582

    The radiation and/or heat sensitivity of Chinese hamster V79 cells, Friend erythroleukemia (FELC) mouse cells, and MOLT-4 human transformed thymocytes were compared. MOLT-4 cells were more radiosensitive (D/sub o/=0.50 Gy) than FELC (D/sub o/ = 0.65 Gy) and V79 cells (D/sub o/ = 1.43 Gy). Arrhenius analysis showed that MOLT-4 cells were more heat sensitive than FELC or V79 cells below 42.0/sup 0/C, but more heat resistant at higher temperatures. In addition, the MOLT-4 cells showed a single-heat inactivation energy between 41.0 and 45.0/sup 0/C, while FELC and V79 cells both showed a transition in the inactivation energy at about 43.0 and 43.5/sup 0/C, respectively. These differences may be related to the fact that the upper temperature limit for the development of thermal tolerance during continuous heating was lower for MOLT-4 cells than for FELC or V79 cells. Killing of FELC and V79 cells was dependent on the sequence in which heat and X rays were applied, but the greatest effect was obtained when both treatments were given simultaneously. Recovery occurred when treatments were separated by incubation at 37.0/sup 0/C. The MOLT-4 cells did not show a sequence dependence for heating and irradiation. Survival of MOLT-4 cells after heating and/or irradiation was compared using trypan blue dye exclusion or colony formation. Both assays showed similar qualitative responses, but survival levels measured by the trypan blue assay were much higher than those determined from the colony-forming assay.

    A simple route for improving the potency of progesterone as a modulator of P-gp-mediated multidrug resistance was established by esterification or etherification of hydroxylated 5α/β-pregnane-3,20-dione or 5β-cholan-3-one precursors. X-ray crystallography of representative 7α-, 11α-, and 17α-(2'R/S)-O-tetrahydropyranyl ether diastereoisomers revealed different combinations of axial-equatorial configurations of the anomeric oxygen. Substantial stimulation of accumulation and chemosensitization was observed on K562/R7 erythroleukemia cells resistant to doxorubicin, especially using 7α,11α-O-disubstituted derivatives of 5α/β-pregnane-3,20-dione, among which the 5β-H-7α-benzoyloxy-11α-(2'R)-O-tetrahydropyranyl ether 22a revealed promising properties (accumulation index 2.9, IC50 0.5 μM versus 1.2 and 10.6 μM for progesterone), slightly overcoming those of verapamil and cyclosporin A. Several 7α,12α-O-disubstituted derivatives of 5β-cholan-3-one proved even more active, especially the 7α-O-methoxymethyl-12α-benzoate 56 (accumulation index 3.8, IC50 0.2 μM). The panel of modulating effects from different O-substitutions at a same position suggests a structural influence of the substituent completing a simple protection against stimulating effects of hydroxyl groups on P-gp-mediated transport.

    Although thyroid hormone is a known stimulator of erythropoietic differentiation, severe anemia is sometimes observed in patients with hyperthyroidism and this mechanism is not fully understood. The aim of this study was to investigate the effect of triiodothyronine (T3) on hemin-induced erythropoiesis. Human erythroleukemia K562 cells were used as an erythroid differentiation model. Cell differentiation was induced by hemin and the effect of pre-incubation with T3 (0.1 to 100 nM) was analyzed by measuring the benzidine-positive rate, hemoglobin content, CD71 expression (transferrin receptor), and mRNA expression for transcription factors related to erythropoiesis and thyroid hormone receptors (TRs). Hemin, a promoter of erythroid differentiation, increased the levels of mRNAs for TRα, TRβ, and retinoid X receptor α (RXRα), as well as those for nuclear factor-erythroid 2 (NFE2), GATA-binding protein 1 (GATA1) and GATA-binding protein 2 (GATA2). Lower concentrations of T3 had a stimulatory effect on hemin-induced hemoglobin production (1 and 10 nM), CD71 expression (0.1 nM), and α-globin mRNA expression (1 nM), while a higher concentration of T3 (100 nM) abrogated the stimulatory effect on these parameters. T3 at 100 nM did not affect cell viability and proliferation, suggesting that the abrogation of erythropoiesis enhancement was not due to toxicity. T3 at 100 nM also significantly inhibited expression of GATA2 and RXRα mRNA, compared to 1 nM T3. We conclude that a high concentration of T3 attenuates the classical stimulatory effect on erythropoiesis exerted by a low concentration of T3 in hemin-induced K562 cells. PMID:25787723

    Stress-responsive neuronal membrane glycoprotein M6a (Gpm6a) functions in neurite extension, filopodium and spine formation and synaptogenesis. The mechanisms of Gpm6a action in these processes are incompletely understood. Previously, we identified the actin regulator coronin-1a (Coro1a) as a putative Gpm6a interacting partner. Here, we used co-immunoprecipitation assays with the anti-Coro1a antibody to show that Coro1a associates with Gpm6a in rat hippocampal neurons. By immunofluorescence microscopy, we demonstrated that in hippocampal neurons Coro1a localizes in F-actin-enriched regions and some of Coro1a spots co-localize with Gpm6a labeling. Notably, the over-expression of a dominant-negative form of Coro1a as well as its down-regulation by siRNA interfered with Gpm6a-induced filopodium formation. Coro1a is known to regulate the plasma membrane translocation and activation of small GTPase Rac1. We show that Coro1a co-immunoprecipitates with Rac1 together with Gpm6a. Pharmacological inhibition of Rac1 resulted in a significant decrease in filopodium formation by Gpm6a. The same was observed upon the co-expression of Gpm6a with the inactive GDP-bound form of Rac1. In this case, the elevated membrane recruitment of GDP-bound Rac1 was detected as well. Moreover, the kinase activity of the p21-activated kinase 1 (Pak1), a main downstream effector of Rac1 that acts downstream of Coro1a, was required for Gpm6a-induced filopodium formation. Taken together, our results provide evidence that a signaling pathway including Coro1a, Rac1, and Pak1 facilitates Gpm6a-induced filopodium formation. Formation of filopodia by membrane glycoprotein M6a (Gpm6a) requires actin regulator coronin-1a (Coro1a), known to regulate plasma membrane localization and activation of Rac1 and its downstream effector Pak1. Coro1a associates with Gpm6a. Blockage of Coro1a, Rac1, or Pak1 interferes with Gpm6a-induced filopodium formation. Moreover, Gpm6a facilitates Rac1 membrane recruitment

    PubMed

    Charlemaine, Christiane

    2006-12-31

    This paper explores the deep roots of closeness that twins share in their youngest age and their effect on their destiny at the adult age. Psychologists believe the bond between twins begins in utero and develops throughout the twins' lives. The four patterns of twinship described show that the twin bond is determined by the quality of parenting that twins receive in their infancy and early childhood. Common problems of adult twins bring about difficulties to adapt in a non-twin world. The nature versus nurture controversy has taken on new life focusing on inter-twin differences and the importance of parent-child interaction as fundamental to the growth and development of personality.

  13. Adult Cancers in Adolescents and Young Adults.

    PubMed

    Laurence, Valérie; Marples, Maria; Stark, Daniel P

    2016-01-01

    The pattern of cancer seen in young people changes with increasing age, transitioning from childhood- to adult-type cancer in adolescence and the third decade. The risk factors, presentation and biology of cancer in young adults differ from those in the older adult population. Factors of particular significance in adolescents and young adults (AYAs) include genetic predisposition to adult-type cancer, diagnostic uncertainty, long-term morbidity and considerations of fertility. New systemic therapies are being introduced that can prolong life and even increase the chance of cure, but the impact on AYAs is uncertain, as these patients are often under-represented in clinical trials. Here, we discuss the management of AYAs with 3 of the most common cancers affecting adults, when they emerge in the AYA populations, and therefore are currently met by medical oncologists - breast cancer, colorectal cancer and melanoma.

    PubMed

    Zucker, Kenneth J; Lawrence, Anne A; Kreukels, Baudewijntje P C

    2016-03-28

    Gender dysphoria (GD), a term that denotes persistent discomfort with one's biologic sex or assigned gender, replaced the diagnosis of gender identity disorder in the Diagnostic and Statistical Manual of Mental Disorders in 2013. Subtypes of GD in adults, defined by sexual orientation and age of onset, have been described; these display different developmental trajectories and prognoses. Prevalence studies conclude that fewer than 1 in 10,000 adult natal males and 1 in 30,000 adult natal females experience GD, but such estimates vary widely. GD in adults is associated with an elevated prevalence of comorbid psychopathology, especially mood disorders, anxiety disorders, and suicidality. Causal mechanisms in GD are incompletely understood, but genetic, neurodevelopmental, and psychosocial factors probably all contribute. Treatment of GD in adults, although largely standardized, is likely to evolve in response to the increasing diversity of persons seeking treatment, demands for greater client autonomy, and improved understanding of the benefits and limitations of current treatment modalities.

    Ling, Pamela M.; Neilands, Torsten B.; Glantz, Stanton A.

    2009-01-01

    Background Young adults have the highest smoking rate of any age group in the U.S., and new strategies to decrease young adult smoking are needed. The objective of the current study was to identify psychographic and demographic factors associated with current smoking and quitting behaviors among young adults. Methods Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18–25 years) from a web-enabled panel. Analyses were conducted in 2007. Results Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR= 4.43 [95% CI=2.18, 8.60]). Conclusions Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking. PMID:19269128

  5. Depression in Older Adults

    Fiske, Amy; Wetherell, Julie Loebach; Gatz, Margaret

    2010-01-01

    Depression is less prevalent among older adults than among younger adults but can have serious consequences. Over half of cases represent a first onset in later life. Although suicide rates in the elderly are declining, they are still higher than in younger adults and more closely associated with depression. Depressed older adults are less likely to endorse affective symptoms and more likely to display cognitive changes, somatic symptoms, and loss of interest than are younger adults. Risk factors leading to the development of late life depression likely comprise complex interactions among genetic vulnerabilities, cognitive diathesis, age-associated neurobiological changes, and stressful events. Insomnia is an often overlooked risk factor for late life depression. We suggest that a common pathway to depression in older adults, regardless of which predisposing risks are most prominent, may be curtailment of daily activities. Accompanying self-critical thinking may exacerbate and maintain a depressed state. Offsetting the increasing prevalence of certain risk factors in late life are age-related increases in psychological resilience. Other protective factors include higher education and socioeconomic status, engagement in valued activities, and religious or spiritual involvement. Treatments including behavioral therapy, cognitive behavioral therapy, cognitive bibliotherapy, problem-solving therapy, brief psychodynamic therapy, and life review/reminiscence therapy are effective but too infrequently used with older adults. Preventive interventions including education for individuals with chronic illness, behavioral activation, cognitive restructuring, problem-solving skills training, group support, and life review have also received support.

    2016-01-01

    Brainstem gliomas are not nearly as common in adults as they are in children. They are likely the final common consequence not of a single disease process but of several. They can be difficult to diagnose, and are challenging to treat. Clinical studies of this diagnosis are few and generally small. Because of these factors, our understanding of the biology of adult brainstem glioma is incomplete. However, the knowledge base is growing and progress is being made. In this article, we review the current state of knowledge for brainstem glioma in adults and identify key areas for which additional information is required. PMID:27556016

  15. Adult Neurogenesis in Fish.

    PubMed

    Ganz, Julia; Brand, Michael

    2016-01-01

    Teleost fish have a remarkable neurogenic and regenerative capacity in the adult throughout the rostrocaudal axis of the brain. The distribution of proliferation zones shows a remarkable conservation, even in distantly related teleost species, suggesting a common teleost ground plan of proliferation zones. There are different progenitor populations in the neurogenic niches-progenitors positive for radial glial markers (dorsal telencephalon, hypothalamus) and progenitors with neuroepithelial-like characteristics (ventral telencephalon, optic tectum, cerebellum). Definition of these progenitors has allowed studying their role in normal growth of the adult brain, but also when challenged following a lesion. From these studies, important roles have emerged for intrinsic mechanisms and extrinsic signals controlling the activation of adult neurogenesis that enable regeneration of the adult brain to occur, opening up new perspectives on rekindling regeneration also in the context of the mammalian brain.

    Pancreatoblastoma is a malignant pancreatic tumor that rarely occurs in adults. We report a case of an adult female with pancreatoblastoma. A mass was detected in the pancreatic head using computed tomography and ultrasonography. The clinical diagnosis was a solid-pseudopapillary neoplasm of the pancreas. However, after the operation, the final diagnosis was pancreatoblastoma, which showed two lines of differentiation: Acinar differentiation and squamoid corpuscles. The patient is currently in good condition. PMID:25673604

  20. Adult educators' core competences

    NASA Astrophysics Data System (ADS)

    Wahlgren, Bjarne

    2016-05-01

    Which competences do professional adult educators need? This research note discusses the topic from a comparative perspective, finding that adult educators' required competences are wide-ranging, heterogeneous and complex. They are subject to context in terms of national and cultural environment as well as the kind of adult education concerned (e.g. basic education, work-related education etc.). However, it seems that it is possible to identify certain competence requirements which transcend national, cultural and functional boundaries. This research note summarises these common or "core" requirements, organising them into four thematic subcategories: (1) communicating subject knowledge; (2) taking students' prior learning into account; (3) supporting a learning environment; and (4) the adult educator's reflection on his or her own performance. At the end of his analysis of different competence profiles, the author notes that adult educators' ability to train adult learners in a way which then enables them to apply and use what they have learned in practice (thus performing knowledge transfer) still seems to be overlooked.

    Reyes-Botero, German; Mokhtari, Karima; Martin-Duverneuil, Nadine; Delattre, Jean-Yves

    2012-01-01

    Brainstem gliomas are uncommon in adults and account for only 1%–2% of intracranial gliomas. They represent a heterogeneous group of tumors that differ from those found in their pediatric counterparts. In adults, a low-grade phenotype predominates, which is a feature that likely explains their better prognosis compared to that in children. Because biopsies are rarely performed, classifications based on the radiological aspect of magnetic resonance imaging results have been proposed to establish treatment strategies and to determine outcomes: (a) diffuse intrinsic low-grade, (b) enhancing malignant glioma, (c) focal tectal gliomas, and (d) exophytic gliomas. Despite significant advances in neuroradiology techniques, a purely radiological classification remains imperfect in the absence of a histological diagnosis. Whereas a biopsy may often be reasonably avoided in the diffuse nonenhancing forms, obtaining histological proof seems necessary in many contrast-enhanced brainstem lesions because of the wide variety of differential diagnoses in adults. Conventional radiotherapy is the standard treatment for diffuse intrinsic low-grade brainstem gliomas in adults (the median survival is 5 years). In malignant brainstem gliomas, radiotherapy is the standard treatment. However, the possible benefit of combined radiotherapy and chemotherapy (temozolomide or other agents) has not been thoroughly evaluated in adults. The role of anti-angiogenic therapies in brainstem gliomas remains to be defined. A better understanding of the biology of these tumors is of primary importance for identifying homogeneous subgroups and for improving therapy options and outcomes. PMID:22382458

    2016-07-01

    Retinoblastoma (RB) is the most common primary malignant intraocular tumor of childhood presenting usually before 5 years of age. RB in adults older than 20 years is extremely rare. A literature search using PubMed/PubMed Central, Scopus, Google Scholar, EMBASE, and Cochrane databases revealed only 45 cases till date. Over the past decade, there has been a significant increase in the number of such reports, indicating heightened level of suspicion among ophthalmologists. Compared to its pediatric counterpart, adult onset RB poses unique challenges in diagnosis and treatment. This article summarizes available literature on adult onset RB and its clinical and pathologic profile, genetics, association with retinocytoma, diagnostics, treatment, and outcomes. PMID:27609158

    2011-01-01

    Seborrheic dermatitis is a common chronic-recurrent inflammatory disorder that most commonly affects adults; however, a more transient infantile form also occurs. The definitive cause of seborrheic dermatitis is unknown. However, proliferation of Malassezia species has been described as a contributing factor. The adult form of seborrheic dermatitis affects up to approximately five percent of the general population. The disorder commonly affects the scalp, face, and periauricular region, with the central chest, axillae, and genital region also involved in some cases. Pruritus is not always present and is relatively common, especially with scalp disease. A variety of treatments are available including topical corticosteroids, topical antifungal agents, topical calcineurin inhibitors, and more recently, a nonsteroidal “device ”cream. This article reviews the practical topical management of seborrheic dermatitis in the United States, focusing on the adult population. PMID:21607192

    PubMed Central

    2008-01-01

    Introduction An estimated 4000 million cases of diarrhoea occurred worldwide in 1996, resulting in 2.5 million deaths. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for acute diarrhoea in adults living in resource-rich countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries traveling to resource-poor countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults living in resource-poor countries? What are the effects of treatments for acute severe diarrhoea in adults living in resource-poor countries? We searched: Medline, Embase, The Cochrane Library and other important databases up to January 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 71 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, antimotility agents, antisecretory agents, bismuth subsalicylate, diet, intravenous rehydration, nasogastric tube rehydration, and oral rehydration solutions (amino acid oral rehydration solution, bicarbonate oral rehydration solution, reduced osmolarity oral rehydration solution, rice-based oral rehydration solution, standard oral rehydration solution).

    Rhinitis symptoms of rhinorrhea, congestion, sneezing, nasal/ocular pruritis, and postnasal drainage can significantly affect the quality of life for older adults. As the US population ages, it will be increasingly important for healthcare providers to effectively diagnose and manage rhinitis. Rhinitis is categorized broadly into allergic rhinitis and non-allergic rhinitis. Environmental changes and avoidance measures are a primary means of intervention. In addition, there are several topical therapies (nasal sprays) that can be effective for symptom control. PMID:23389558

  12. [Intraosseous infusion for adults].

    PubMed

    Leidel, B A; Kirchhoff, C

    2008-04-01

    Intraosseous (IO) infusion methods have been common for emergency treatment in infants and children for years. The role of IO access in adults is however much less clear, but its importance in this patient group is increasing, and different devices are available today. Each device has strengths and weaknesses, but all achieve rapid vascular access even in challenging situations. The potential of IO access regarding both therapeutic and diagnostic options has been shown in several operational studies in and out of hospital. Insertion times require between 1 and 2 min in most cases, while insertion and handling of the IO access devices seem to be easy and reliable. The flow rates of IO access devices for adults are lower than those of large-bore peripheral intravenous catheters, but fluid resuscitation is possible in most cases at least with pressure bag infusion systems. Most drugs administered intravenously can be given intraosseously in equivalent dosages and with the same effects. Nevertheless the limitations and risks of IO access routes need to be considered for each application. Rapid IO access is now possible in all age groups, and the 2005 AHA Guidelines favor it over drug administration via the endotracheal tube. PMID:18250995

  13. Human metapneumovirus in adults.

    PubMed

    Haas, Lenneke E M; Thijsen, Steven F T; van Elden, Leontine; Heemstra, Karen A

    2013-01-01

    Human metapneumovirus (HMPV) is a relative newly described virus. It was first isolated in 2001 and currently appears to be one of the most significant and common human viral infections. Retrospective serologic studies demonstrated the presence of HMPV antibodies in humans more than 50 years earlier. Although the virus was primarily known as causative agent of respiratory tract infections in children, HMPV is an important cause of respiratory infections in adults as well. Almost all children are infected by HMPV below the age of five; the repeated infections throughout life indicate transient immunity. HMPV infections usually are mild and self-limiting, but in the frail elderly and the immunocompromised patients, the clinical course can be complicated. Since culturing the virus is relatively difficult, diagnosis is mostly based on a nucleic acid amplification test, such as reverse transcriptase polymerase chain reaction. To date, no vaccine is available and treatment is supportive. However, ongoing research shows encouraging results. The aim of this paper is to review the current literature concerning HMPV infections in adults, and discuss recent development in treatment and vaccination. PMID:23299785

  6. Adults' conceptions of intelligence across the adult life span.

    PubMed

    Berg, C A; Sternberg, R J

    1992-06-01

    To examine whether young, middle-aged, and older adults view the concept of intelligent person as similar or different during adulthood, 140 adults of various ages rated how likely it would be for individuals of average and exceptional intelligence at 30, 50, and 70 years of age to be engaged in behaviors previously identified by adults as characterizing adult intelligence. Adults perceived more similarity between exceptionally intelligent prototypes of closer ages (i.e., 30 and 50 and 50 and 70). Intelligence was perceived to consist of interest and ability to deal with novelty, everyday competence, and verbal competence--dimensions that were perceived to be differentially important for different-aged prototypes and by individuals of different ages. Participants' conceptions also included the idea that intelligence is malleable and that abilities differentially increase or decrease across the life span. PMID:1610512

    Cellier, C; Grosdidier, E

    2001-05-15

    Celiac disease is much common than previously thought with a prevalence of 1/300, but most of cases are poorly symptomatic or silent. Fewer of half of patients report diarrhoea as a presenting symptom. In adults, the diagnosis should be considered, in case of isolated iron deficiency anaemia, neurological symptoms (ataxia, epilepsy), osteoporosis and arthralgia, infertility, dermatitis herpetiformis and abnormalities in liver tests. Characteristic histological features are total or subtotal villous atrophy associated with an increased number of intraepithelial lymphocytes. The most sensitive and specific circulating antibodies for the diagnosis are endomysial and transglutaminase IgA antibodies. The treatment of celiac disease requires a strict gluten free diet, but the observance to this diet is often difficult. In patients refractory to a strict gluten free diet, serious complications such as intestinal lymphoma or refractory sprue should be considered. PMID:11458609

    Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought. Worsening of renal function after starting an angiotensin-converting enzyme inhibitor suggests the possibility of renal artery stenosis. Recognition, diagnosis and treatment of secondary causes of hypertension lead to good clinical outcomes and the possible reversal of end-organ damage, in addition to blood pressure control. As most patients with hypertension are managed at the primary care level, it is important for primary care physicians to recognise these conditions and refer patients appropriately. PMID:27211205

  9. Extravasation Injuries in Adults

    PubMed Central

    Al-Benna, S.; O'Boyle, C.; Holley, J.

    2013-01-01

    Insertion of an intravascular catheter is one of the most common invasive procedures in hospitals worldwide. These intravascular lines are crucial in resuscitation, allow vital medication to be administered, and can be used to monitor the patients' real-time vital parameters. There is, however, growing recognition of potential risks to life and limb associated with their use. Medical literature is now replete with isolated case reports of complications succinctly described by Garden and Laussen (2004) as “An unending supply of “unusual” complications from central venous catheters.” This paper reviews complications of venous and arterial catheters and discusses treatment approaches and methods to prevent complications, based on current evidence and endeavours to provide information and guidance that will enable practitioners to prevent, recognise, and successfully treat extravasation injuries in adults.

  10. Adult Olfactory Bulb Neurogenesis.

    PubMed

    Lledo, Pierre-Marie; Valley, Matt

    2016-01-01

    Most organisms use their olfactory system to detect and analyze chemical cues from the external world to guide essential behaviors. From worms to vertebrates, chemicals are detected by odorant receptors expressed by olfactory sensory neurons, which in vertebrates send an axon to the primary processing center called the olfactory bulb (OB). Within the OB, sensory neurons form excitatory synapses with projection neurons and with inhibitory interneurons. Thus, because of complex synaptic interactions, the output of a given projection neuron is determined not only by the sensory input, but also by the activity of local inhibitory interneurons that are regenerated throughout life in the process of adult neurogenesis. Herein, we discuss how it is optimized and why. PMID:27235474

  11. The older adult driver.

    PubMed

    Carr, D B

    2000-01-01

    More adults aged 65 and older will be driving in the next few decades. Many older drivers are safe behind the wheel and do not need intensive testing for license renewal. Others, however, have physiologic or cognitive impairments that can affect their mobility and driving safety. When an older patient's driving competency is questioned, a comprehensive, step-by-step assessment is recommended. Many diseases that impair driving ability can be detected and treated effectively by family physicians. Physicians should take an active role in assessing and reducing the risk for injury in a motor vehicle and, when possible, prevent or delay driving cessation in their patients. Referral to other health care professionals, such as an occupational or physical therapist, may be helpful for evaluation and treatment. When an older patient is no longer permitted or able to drive, the physician should counsel the patient about using alternative methods of transportation. PMID:10643955

  12. Adult coeliac disease.

    PubMed

    Marmouz, F

    2007-01-01

    Coeliac disease is an auto-immune inflammatory reaction characterized by a partial or total villi's atrophy of the proximal small intestine occuring after ingestion of gluten in genetically predisposed patients. The classic form is much more frequent in children. Thereby there has been a misevaluation and improper treatment of coeliac disease in adults who suffer more from asymptomatica and atypical forms. Currently the only effective treatment is a strict gluten free diet for life. However recent researches brought a new light on the matter. Now oats as a causative factor is controvertial. The introduction of some moderate intestinal lesions (pre-atrophic with intra-epithelial hyperlymphocytosis qualified as "weak enteropathies") in the definition of coeliac disease might be possible. Moreover the way to diagnose has evolved as serological tests and markers are more used due to their efficiency. PMID:17375738

    The number of older adults living in the USA, 65 years of age and older, has been steadily increasing. Data from the National Health and Nutrition Examination Survey (NHANES), 2007-2010, indicate that more than one-third of older adults, 65 years of age and older, were obese. With the increased rate of obesity in older adults, the purpose of this paper is to present research on different methods to prevent or manage obesity in older adults, namely dietary interventions, physical activity interventions, and a combination of dietary and physical activity interventions. In addition, research on community assistance programs in the prevention of obesity with aging will be discussed. Finally, data on federal programs for older adults will also be presented.

    2007-02-01

    Attachment scores for 658 young adults living in the U.S.A. were obtained using the Experiences in Close Relationships scale. The participants came from a subsample of the RELATE data set, who had also filled out the adult attachment measure. Those young adults living in Utah County, Utah, an area of the country with a higher than normal birthrate (88% members of the Church of Jesus Christ of Latter-day Saints), also had higher than average adult attachment scores. While the methodology was not sufficient to assess causal direction nor eliminate the possibility of unidentified influences, an undiscussed psychological factor, adult attachment, may play a role in the numerical declines observed among nonimmigrant communities in the USA and Europe.

    PubMed

    Wallace, Steven P; Padilla-Frausto, D Imelda

    2014-02-01

    This policy brief looks at the financial burdens imposed on older Californians when adult children return home, often due to a crisis not of their own making, to live with their parents. The findings show that on average in California, the amount of money that older adults need in order to maintain a minimally decent standard of living while supporting one adult child in their home increases their expenses by a minimum of 50 percent. Low-income older adults are usually on fixed incomes, so helping an adult child can provide the child with a critical safety net but at the cost of the parents' own financial well-being. Policy approaches to assisting this vulnerable population of older adults include implementing reforms to increase Supplemental Security Income (SSI), improving the availability of affordable housing, assuring that all eligible nonelderly adults obtain health insurance through health care reform's expansion of Medi-Cal and subsidies, and increasing food assistance through SNAP and senior meal programs.

  15. Vitalistic thinking in adults.

    PubMed

    Wilson, Stuart

    2013-11-01

    Vitalistic thinking has traditionally been associated with reasoning about biological phenomena. The current research aimed to investigate a broader range of vitalistic thinking than previously studied. Esoteric notions of 'energy' are frequently used by individuals when making causal attributions for strange occurrences, and previous literature has linked such thinking with paranormal, magical, and superstitious beliefs. Two experiments are described that aim to investigate whether adults are vitalistic when asked to make causal judgments, and whether this can be predicted by thinking styles and prior paranormal belief. Experiment 1 asked participants to rate three causal options (one of which was vitalistic) for six vignettes. Scores on one dimension of paranormal belief (New Age Philosophy) and analytical thinking significantly predicted vitalism, but scores on intuitive thinking and Traditional Paranormal Beliefs did not. Experiment 2 extended the findings by asking participants to generate their own causal responses. Again, paranormal belief was found to be the best predictor of vitalism, but this time Traditional Paranormal Beliefs were associated with vitalistic responses whilst both intuitive and analytical thinking were unable to significantly predict classification. Results challenge previous findings, suggesting that vitalistic thinking may operate differently when applied to everyday causal reasoning. PMID:24094281

    2016-02-01

    After securing vital function, treatment of pain is an important aspect in emergency medical care. Irrespective of the underlying disease or injury, pain is an important warning symptom of the body and the most common reason for an emergency alert notification. A patient assesses quality of care and success of prehospital care using the criteria of the extent of pain relief he experiences. Since mild pain does not usually lead to an emergency alert, the criteria apply mainly to treatment of severe and very severe pain. Pain perception varies from individual to individual. Accordingly, assessment of pain intensity is the very first step in pain therapy. The Numeric Rating Scale (NRS) ranging from 0 (no pain) to 10 (worst pain imaginable) is suitable for pain assessment in adult emergency patients. Above a grade of 4, therapeutic intervention should be initiated with the goal of reducing pain to reach a value of <4, or at least to achieve a reduction by 3 points. The choice of analgesics that can be meaningfully used in pre-hospital emergency medicine is limited. The emergency physician should be aware of available drugs and administration routes.

    2016-01-01

    Abstract Objective To describe updates to the Preventive Care Checklist Form© to help family physicians stay up to date with current preventive health care recommendations. Quality of evidence The Ovid MEDLINE database was searched using specified key words and other terms relevant to the periodic health examination. Secondary sources, such as the Canadian Task Force on Preventive Health Care, the Public Health Agency of Canada, the Trip database, and the Canadian Medical Association Infobase, were also searched. Recommendations for preventive health care for average-risk adults were reviewed. Strong and weak recommendations are presented on the form in bold and italic text, respectively. Main message Updates were made to the form based on the Canadian Task Force on Preventive Health Care recommendations on screening for obesity (2015), cervical cancer (2013), depression (2013), osteoporosis (2013), hypertension (2012), diabetes (2012, 2013), and breast cancer (2011). Updates were made based on recommendations from other Canadian organizations on screening for HIV (2013), screening for sexually transmitted infections (2013), immunizations (2012 to 2014), screening for dyslipidemia (2012), fertility counseling for women (2011, 2012), and screening for colorectal cancer (2010). Some previous recommendations were removed and others lacking evidence were not included. Conclusion The Preventive Care Checklist Form has been updated with current recommendations to enable family physicians to provide comprehensive, evidence-based care to patients during periodic health examinations.

    Cecchi, Guillermo A.; Magnasco, Marcelo O.

    2005-10-01

    Experimental results in recent years have shown that adult neurogenesis is a significant phenomenon in the mammalian brain. Little is known, however, about the functional role played by the generation and destruction of neurons in the context of an adult brain. Here, we propose two models where new projection neurons are incorporated. We show that in both models, using incorporation and removal of neurons as a computational tool, it is possible to achieve a higher computational efficiency that in purely static, synapse-learning-driven networks. We also discuss the implication for understanding the role of adult neurogenesis in specific brain areas like the olfactory bulb and the dentate gyrus.

  1. Adult Hirschprung disease: radiographic findings.

    PubMed

    Mindelzun, R E; Hicks, S M

    1986-09-01

    Hirschprung disease is usually diagnosed in infancy. Occasionally patients reach adulthood without diagnosis or treatment. Four cases of adult Hirschprung disease are described. The principal radiographic findings are a markedly dilated, feces-filled colon above the zone of transition; a narrowed rectum; a cone- or funnel-shaped zone of transition; and a mosaic colonic pattern caused by collapsed redundant mucosa after colonic cleansing. In an adult, identification on a barium enema examination of an abrupt, smooth transition zone in the rectum with proximal colonic dilatation, in conjunction with an appropriate clinical history, should suggest the diagnosis of adult Hirschprung disease.

  2. Thematic relations in adults' concepts.

    PubMed

    Lin, E L; Murphy, G L

    2001-03-01

    Concepts can be organized by their members' similarities, forming a kind (e.g., animal), or by their external relations within scenes or events (e.g., cake and candles). This latter type of relation, known as the thematic relation, is frequently found to be the basis of children's but not adults' classification. However, 10 experiments found that when thematic relations are meaningful and salient, they have significant influence on adults' category construction (sorting), inductive reasoning, and verification of category membership. The authors conclude that concepts function closely with knowledge of scenes and events and that this knowledge has a role in adults' conceptual representations. PMID:11293459

    Even though computers play a massive role in everyday life of modern societies, older adults, and especially older women, are less likely to use a computer, and they perform fewer activities on it than younger adults. To get a better understanding of the factors affecting older adults' intention towards and usage of computers, the Unified Theory of Acceptance and Usage of Technology (UTAUT) was applied as part of a more extensive study with 52 users and non-users of computers, ranging in age from 50 to 90 years. The model covers various aspects of computer usage in old age via four key constructs, namely performance expectancy, effort expectancy, social influences, and facilitating conditions, as well as the variables gender, age, experience, and voluntariness it. Interestingly, next to performance expectancy, facilitating conditions showed the strongest correlation with use as well as with intention. Effort expectancy showed no significant correlation with the intention of older adults to use a computer. PMID:22317258

    In August 2015, an expert colloquium commissioned by the Sexual Medicine Society of North America (SMSNA) convened in Washington, DC, to discuss the common clinical scenario of men who present with low testosterone (T) and associated signs and symptoms accompanied by low or normal gonadotropin levels. This syndrome is not classical primary (testicular failure) or secondary (pituitary or hypothalamic failure) hypogonadism because it may have elements of both presentations. The panel designated this syndrome adult-onset hypogonadism (AOH) because it occurs commonly in middle-age and older men. The SMSNA is a not-for-profit society established in 1994 to promote, encourage, and support the highest standards of practice, research, education, and ethics in the study of human sexual function and dysfunction. The panel consisted of 17 experts in men's health, sexual medicine, urology, endocrinology, and methodology. Participants declared potential conflicts of interest and were SMSNA members and nonmembers. The panel deliberated regarding a diagnostic process to document signs and symptoms of AOH, the rationale for T therapy, and a monitoring protocol for T-treated patients. The evaluation and management of hypogonadal syndromes have been addressed in recent publications (ie, the Endocrine Society, the American Urological Association, and the International Society for Sexual Medicine). The primary purpose of this document was to support health care professionals in the development of a deeper understanding of AOH, particularly in how it differs from classical primary and secondary hypogonadism, and to provide a conceptual framework to guide its diagnosis, treatment, and follow-up.

  12. Asthma in adults (acute)

    PubMed Central

    2011-01-01

    Introduction About 10% of adults have suffered an attack of asthma, and up to 5% of these have severe disease that responds poorly to treatment. Patients with severe disease have an increased risk of death, but patients with mild to moderate disease are also at risk of exacerbations. Most guidelines about the management of asthma follow stepwise protocols. This review does not endorse or follow any particular protocol, but presents the evidence about specific interventions. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute asthma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 100 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: beta2 agonists (plus ipratropium bromide, pressured metered-dose inhalers, short-acting continuous nebulised, short-acting intermittent nebulised, short-acting iv, and inhaled formoterol); corticosteroids (inhaled); corticosteroids (single oral, combined inhaled, and short courses); education about acute asthma; generalist care; helium–oxygen mixture (heliox); magnesium sulphate (iv and adding isotonic nebulised magnesium to inhaled beta2 agonists); mechanical ventilation; oxygen supplementation (controlled 28% oxygen and controlled 100% oxygen); and specialist care.

    Hepatoblastoma is the most frequent primary malignant liver neoplasm in childhood; in adults it is extremely rare and only 27 cases have been published. The prognosis of this neoplasm is poor because it is usually discovered late. Surgery, chemotherapy and liver transplantation have been tried with poor results. We present two adult patients who were diagnosed with an epithelial hepatoblastoma. The pathogenesis, histologic features and current management is reviewed. PMID:7716366

    Geraerts, Martine; Verfaillie, Catherine M.

    The discovery of adult stem cells in most adult tissues is the basis of a number of clinical studies that are carried out, with therapeutic use of hematopoietic stem cells as a prime example. Intense scientific debate is still ongoing as to whether adult stem cells may have a greater plasticity than previously thought. Although cells with some features of embryonic stem cells that, among others, express Oct4, Nanog and SSEA1 are isolated from fresh tissue, it is not clear if the greater differentiation potential is acquired during cell culture. Moreover, adult more pluripotent cells do not have all pluripotent characteristics typical for embryonic stem cells. Recently, some elegant studies were published in which adult cells could be completely reprogrammed to embryonic stem cell-like cells by overexpression of some key transcription factors for pluripotency (Oct4, Sox2, Klf4 and c-Myc). It will be interesting for the future to investigate the exact mechanisms underlying this reprogramming and whether similar transcription factor pathways are present and/or can be activated in adult more pluripotent stem cells.

  12. Adults with ADHD. An overview.

    PubMed

    Wender, P H; Wolf, L E; Wasserstein, J

    2001-06-01

    Attention-Deficit Hyperactivity Disorder (ADHD) is a common, genetically transmitted neurological disorder, with onset in childhood, probably mediated by decreased brain dopaminergic functioning. The first author was one of the earliest to describe the persistence of symptoms into adulthood. Prevalence and natural history data suggest that of the 3 to 10% of children diagnosed with ADHD, one- to two-thirds (somewhere between 1 and 6% of the general population) continue to manifest appreciable ADHD symptoms into adult life. This paper describes how ADHD in adults can be readily diagnosed and treated, despite resembling or coexisting with other psychiatric disorders. The Wender Utah diagnostic criteria address adult characteristics of the disorder. Informant and patient interviews and rating scales are used to determine the psychiatric status of the patient as a child, make a retroactive diagnosis of childhood ADHD, and establish the current diagnosis of the adult. Stringent diagnosis is key to determining effective treatment. Dopamine agonist stimulant medications appear to be the most effective in treating ADHD. About 60% of patients receiving stimulant medication showed moderate-to-marked improvement, as compared with 10% of those receiving placebo. The core symptoms of hyperactivity, inattention, mood lability, temper, disorganization, stress sensitivity, and impulsivity have been shown to respond to treatment with stimulant medications. Non-dopaminergic medications, such as the tricyclic antidepressants and SSRIs have generally not been useful in adults with ADHD in the absence of depression or dysthymia. Pemoline is no longer approved for use in these patients, despite early favorable reports. Appropriate management of adult patients with ADHD is multimodal. Psychoeducation, counseling, supportive problem-directed therapy, behavioral intervention, coaching, cognitive remediation, and couples and family therapy are useful adjuncts to medication management

  13. Simulated microgravity inhibits the proliferation of K562 erythroleukemia cells but does not result in apoptosis

    Astronauts and experimental animals in space develop the anemia of space flight, but the underlying mechanisms are still unclear. In this study, the impact of simulated microgravity on proliferation, cell death, cell cycle progress and cytoskeleton of erythroid progenitor-like K562 leukemia cells was observed. K562 cells were cultured in NASA Rotary Cell Culture System (RCCS) that was used to simulate microgravity (at 15 rpm). After culture for 24 h, 48 h, 72 h, and 96 h, the cell densities cultured in RCCS were only 55.5%, 54.3%, 67.2% and 66.4% of the flask-cultured control cells, respectively. The percentages of trypan blue-stained dead cells and the percentages of apoptotic cells demonstrated no difference between RCCS-cultured cells and flask-cultured cells at every time points (from 12 h to 96 h). Compared with flask-cultured cells, RCCS culture induced an accumulation of cell number at S phase concomitant with a decrease at G0/G1 and G2/M phases at 12 h. But 12 h later (from 24 h to 60 h), the distribution of cell cycle phases in RCCS-cultured cells became no difference compared to flask-cultured cells. Consistent with the changes of cell cycle distribution, the levels of intercellular cyclins in RCCS-cultured cells changed at 12 h, including a decrease in cyclin A, and the increasing in cyclin B, D1 and E, and then (from 24 h to 36 h) began to restore to control levels. After RCCS culture for 12-36 h, the microfilaments showed uneven and clustered distribution, and the microtubules were highly disorganized. These results indicated that RCCS-simulated microgravity could induce a transient inhibition of proliferation, but not result in apoptosis, which could involve in the development of space flight anemia. K562 cells could be a useful model to research the effects of microgravity on differentiation and proliferation of hematopoietic cells.

    A Total Oligomers Flavonoids (TOFs) and ethyl acetate extracts of Cyperus rotundus were analyzed, in vitro, for their antioxidant activity using several biochemical assays: the xanthine (X)/xanthine oxidase (XO), the lipid peroxidation induced by H(2)O(2) in K562 human chronic myelogenous leukemia cells and the DNA damage in pKS plasmid DNA assay induced by H(2)O(2)/UV-photolysis and for their apoptotic effect. TOF and ethyl acetate extracts were found to be efficient in inhibiting xanthine oxidase with IC(50) values of 240 and 185 microg/ml and superoxide anion with IC(50) values of 150 and 215 microg/ml, respectively. Also, all the extracts tested were effective in reducing the production of thiobarbituric acid reactive substances (TBARS) and were able to protect against H(2)O(2)/UV-photolysis induced DNA damage. The highest activity, measured as equivalents of MDA concentration, was observed in the ethyl acetate extract (MDA=2.04 nM). In addition, the data suggest that only TOF enriched extract exerts growth inhibition on K562 cells through apoptosis induction. Therefore, these extracts were subjected to further separation by chromatographic methods. Thus, three major compounds (catechin, afzelechin and galloyl quinic acid) were isolated from the TOF enriched extract and five major compounds (luteolin, ferulic acid, quercetin, 3-hydroxy, 4-methoxy-benzoic acid and 6,7-dimethoxycoumarin) from ethyl acetate extract. Their structures were determined by spectroscopic data analysis and comparison with the literature. In addition, we evaluate the biological activities of the catechin, ferulic acid and luteolin. This investigation has revealed that the luteolin was the most active in reducing the production of TBARS (MDA=1.5 nM), inhibiting significantly the proliferation of K562 cells (IC(50)=25 microg/ml) and protecting against H(2)O(2)/UV-photolysis induced DNA damage. In conclusion, the study reveals that the ability of C. rotundus to inhibit the enzyme xanthine oxidase (XO), the lipid peroxidation and to exert apoptotic effect, may explain possible mechanisms by which C. rotundus exhibits its health benefits.

  17. Psychological distress among homeless adults.

    PubMed

    Gelberg, L; Linn, L S

    1989-05-01

    Recent studies have reported a high prevalence of mental illness among the homeless. As part of a community-based survey of 529 homeless adults, we developed and tested a model to increase our understanding of the factors related to their psychological distress. Using a previously validated and reliable scale of perceived psychological distress, we found that homeless adults were more likely to report psychological distress than the general population (80% vs. 49%). Distress levels were not associated with most demographic or homeless characteristics or general appearance. However, distress was related to unemployment, greater cigarette and alcohol use, worse physical health, fewer social supports, and perceived barriers to obtaining needed medical care. Since mental, physical, and social health are strongly related among homeless adults, alleviating distress among them may be most effectively done by implementing a broad-based health services package coupled with employment programs provided in an accessible service delivery setting.

  18. Adult Neurogenesis and Mental Illness

    PubMed Central

    Schoenfeld, Timothy J; Cameron, Heather A

    2015-01-01

    Several lines of evidence suggest that adult neurogenesis, the production of new neurons in adulthood, may play a role in psychiatric disorders, including depression, anxiety, and schizophrenia. Medications and other treatments for mental disorders often promote the proliferation of new neurons; the time course for maturation and integration of new neurons in circuitry parallels the delayed efficacy of psychiatric therapies; adverse and beneficial experiences similarly affect development of mental illness and neurogenesis; and ablation of new neurons in adulthood alters the behavioral impact of drugs in animal models. At present, the links between adult neurogenesis and depression seem stronger than those suggesting a relationship between new neurons and anxiety or schizophrenia. Yet, even in the case of depression there is currently no direct evidence for a causative role. This article reviews the data relating adult neurogenesis to mental illness and discusses where research needs to head in the future. PMID:25178407

    Adult hepatoblastoma is a rare pathology. Its pathogeny is not well understood and prognosis is very bad. We pre-sent a case of adult hepatoblastoma treated in our centre. A 65 year-old male, without previous hepatopathy, who consulted due to right hypochondrial pain with a subacute evolution. The pathological diagnosis was adult epithelial hepatoblastoma, with free surgical margins. The patient recei-ved a second surgical intervention 5 months later due to early recurrence and died 10 months after the diagnosis due to a new massive recurrence. His definitive diagnosis is histological. Radical surgery is the only treatment that increases survival, but recurrence is frequent. There are no well-defined patterns of adjuvant chemotherapy nor is there any trans-plant experience. PMID:27599957

    2013-01-01

    We review human studies on the relation between acute exposures to prenatal famine and adult physical and mental health. These studies are observational and include exposures to a famine environment by natural or man-made causes or, more commonly, from the interplay between natural and human factors. These natural experiments provide an opportunity to examine long-term outcomes after famine exposures by comparing exposed and nonexposed individuals. The studies show consistent associations between prenatal famine and adult body size, diabetes, and schizophrenia. For other measures of adult health, findings are less robust. A relation between prenatal famine and some reported epigenetic changes may provide a potential mechanism to explain specific associations. Much progress can be made if current separate studies are further analyzed with comparable definitions of exposures and outcomes and using common analytic strategies. PMID:21219171

    Vaccine response declines with age, but currently recommended vaccines are safe and effective in reducing, if not preventing, disease altogether. Over the last decade, advancements in vaccine immunogenicity, either by increasing dose or conjugating vaccines to protein, have resulted in more immunogenic vaccines that also seem more effective in reducing clinical disease both for influenza and pneumococcus. Meanwhile, there is a resurgence in incident pertussis, exceeding prevalence from five decades ago, adding older adults to a recommended target vaccination group. This article discusses currently available vaccines, in the context of current epidemiology and recommendations, for older adults. PMID:27394026

    Water intoxication is a common disorder in calves and is usually characterized by transient hemoglobinuria. In contrast, the condition is very rare in adult cattle, with few reports on naturally occurring cases. In the present report, four female Japanese Black cattle, aged 16-25 months, showed neurological signs when they drank water following a water outage. Hemoglobinuria was not grossly observed, while severe hyponatremia was revealed by laboratory tests. Autopsy indicated cerebral edema with accumulation of serous fluid in expanded Virchow-Robin spaces. These results indicate the possibility of water intoxication associated with cerebral edema due to severe dilutional hyponatremia in adult cattle. PMID:27506091

    Wilms tumor (WT) occurs infrequently in adults. Even rarer is adult WT with extension by direct intravascular spread into the right side of the heart. The present report describes a WT with intracaval and intracardiac extension in a 38-year-young man. In addition, thrombus extension above the infrahepatic IVC represents a major technical topic for surgeons because of the possible occurrence of uncontrollable hemorrhages and tumor fragmentation. We report the results of a surgical approach to caval thrombosis including the isolation of the IVC from the liver as routinely performed during liver harvesting. The morphologic and immune-histochemical findings confirmed the diagnosis. PMID:25553532

    When adult neurogenesis was discovered in the mammalian brain it was often considered an atavism and, even today, many people are convinced that there has been a "phylogenetic reduction" away from lifelong neurogenesis, favoring stability for complex brains. Adult neurogenesis is found throughout the animal kingdom but varies to a large extent. Mammals might have fewer neurogenic zones than, for example, fish, but within their remaining neurogenic zones, the new neurons are highly functional. Especially, humans have very substantial quantities of neurogenesis in their hippocampus. At least for the mammalian dentate gyrus, one can thus argue that there has been evolution toward neurogenesis-based plasticity rather than away from it. PMID:26684183

  5. Catastrophic events and older adults.

    PubMed

    Cloyd, Elizabeth; Dyer, Carmel B

    2010-12-01

    The plight of older adults during catastrophic events is a societal concern. Older persons have an increased prevalence of cognitive disorders, chronic illnesses, and mobility problems that limit their ability to cope. These disorders may result in a lack of mental capacity and the ability to discern when they should evacuate or resolve problems encountered during a catastrophe. Some older persons may have limited transportation options, and many of the elderly survivors are at increased risk for abuse, neglect, and exploitation. Recommendations for future catastrophic events include the development of a federal tracking system for elders and other vulnerable adults, the designation of separate shelter areas for elders and other vulnerable adults, and involvement of gerontological professionals in all aspects of emergency preparedness and care delivery, including training of frontline workers. Preparation through preevent planning that includes region-specific social services, medical and public health resources, volunteers, and facilities for elders and vulnerable adults is critical. Elders need to be protected from abuse and fraud during catastrophic events. A public health triage system for elders and other vulnerable populations in pre- and postdisaster situations is useful, and disaster preparedness is paramount. Communities and members of safety and rescue teams must address ethical issues before an event. When older adults are involved, consideration needs to be given to triage decision making, transporting those who are immobile, the care of older adults who receive palliative care, and the equitable distribution of resources. Nurses are perfectly equipped with the skills, knowledge, and training needed to plan and implement disaster preparedness programs. In keeping with the tradition of Florence Nightingale, nurses can assume several crucial roles in disaster preparedness for older adults. Nurses possess the ability to participate and lead community

  6. [Etiology of adult insomnia].

    PubMed

    Dollander, M

    2002-01-01

    In the article, the author develops an analysis of external and intrapsychic factors related to adults' insomnia. First she undertakes a literature review to describe semiological, evolutive and etiological levels of insomnia. From a semiological point of view, it is usual to differenciate initial insomnia (associated to the first phase of sleeping), intermittent insomnia (related to frequent awakenings) and final insomnia (related to early morning awakenings). From an evolutive point of view, we can identify transitory insomnia (characterized by frequent awakenings) and chronic insomnia. On the other hand, we are allowed to distinguish organic insomnia (disorder where an organic cerebral injury is demonstrated or suspected) from insomnias related to psychiatric or somatic disease or idiopathic one. Then, the author makes a literary review to identify various insomnia causes and points out. Social factors: insomnia rates are higher by divorced, separated or widowed people. Percentages are higher when scholastic level is weak, domestic income is less then 915 O a month, or by unemployed people. Besides, sleep quality is deteriorated by ageing. Sleeping and waking rhythm is able to loose its synchronization. Complaints about insomnia occur far frequently from women than men. Environmental factors: working constraints increase sleep disorders. It is possible to make the same conclusion when we have to face overcharge of external events, deep intrapsychic conflicts (related to grief, unemployment, damage or hospitalization) or interpersonal conflicts' situations where we are confronted to stress related to socio-affective environment, lack of social support or conjugal difficulties. Medical and physiologic causes: legs impatience syndrome, recurrent limbs shakings syndrome, breathe stop during sleep, narcolepsy, excessive medicine or hypnotic drugs use, some central nervous system injuries, every nocturnal awakening (related to aches.), surgical operation

  10. Cardiac Rehabilitation in Older Adults.

    PubMed

    Schopfer, David W; Forman, Daniel E

    2016-09-01

    The biology of aging and the pathophysiology of cardiovascular disease (CVD) overlap, with the effect that CVD is endemic in the growing population of older adults. Moreover, CVD in older adults is usually complicated by age-related complexities, including multimorbidity, polypharmacy, frailty, and other intricacies that add to the risks of ambiguous symptoms, deconditioning, iatrogenesis, falls, disability, and other challenges. Cardiac rehabilitation (CR) is a comprehensive lifestyle program that can have particular benefit for older patients with cardiovascular conditions. Although CR was originally designed primarily as an exercise training program for younger adults after a myocardial infarction or coronary artery bypass surgery, it has evolved as a comprehensive lifestyle program (promoting physical activity as well as education, diet, risk reduction, and adherence) for a broader range of CVD (coronary heart disease, heart failure, and valvular heart disease). It provides a valuable opportunity to address and moderate many of the challenges pertinent for the large and growing population of older adults with CVD. Cardiac rehabilitation promotes physical function (cardiorespiratory fitness as well as strength and balance) that helps overcome disease and deconditioning as well as related vulnerabilities such as disability, frailty, and falls. Similarly, CR facilitates education, monitoring, and guidance to reduce iatrogenesis and promote adherence. Furthermore, CR fosters cognition, socialization, and independence in older patients. Yet despite all its conceptual benefits, CR is significantly underused in older populations. This review discusses benefits and the paradoxical underuse of CR, as well as evolving models of care that may achieve greater application and efficacy. PMID:27297002

  20. Adult Height and Childhood Disease

    PubMed Central

    BOZZOLI, CARLOS; DEATON, ANGUS; QUINTANA-DOMEQUE, CLIMENT

    2009-01-01

    Taller populations are typically richer populations, and taller individuals live longer and earn more. In consequence, adult height has recently become a focus in understanding the relationship between health and wealth. We investigate the childhood determinants of population adult height, focusing on the respective roles of income and of disease. Across a range of European countries and the United States, we find a strong inverse relationship between postneonatal (ages 1 month to 1 year) mortality, interpreted as a measure of the disease and nutritional burden in childhood, and the mean height of those children as adults. Consistent with these findings, we develop a model of selection and stunting in which the early-life burden of undernutrition and disease not only is responsible for mortality in childhood but also leaves a residue of long-term health risks for survivors, risks that express themselves in adult height and in late-life disease. The model predicts that at sufficiently high mortality levels, selection can dominate scarring, leaving a taller population of survivors. We find evidence of this effect in the poorest and highest-mortality countries of the world, supplementing recent findings on the effects of the Great Chinese Famine. PMID:20084823

  20. Liver involvement in adults with measles.

    PubMed

    Dinh, Aurélien; Fleuret, Victoire; Hanslik, Thomas

    2013-12-01

    We retrospectively collected the characteristics of 80 consecutive adult patients with biologically confirmed measles during a recent epidemic in France. We report on the frequency and severity of liver involvement in adult patients with measles. In our experience, measles in adults was not severe and hepatitis was not correlated with severe cases or bacterial infection. Therefore, hepatitis should be regarded as a usual symptom rather than a complication of measles infection in adults. PMID:23938044
