The identification of an interaction between BRCA1 and acetyl-CoA carboxylase alpha (ACCalpha), a key enzyme in lipid synthesis, led us to investigate the role of ACCalpha in breast cancer development, where it might contribute to the energy-sensing mechanisms of malignant transformation. In order to investigate if certain ACCalpha alleles may be high-risk ...

A novel mutant of Arabidopsis thaliana having highly glossy inflorescence stems, post-genital fusion in floral organs, and reduced fertility, was isolated from an EMS-mutagenized population and designated glossyhead1 (gsd1). The gsd1 locus was mapped to chromosome 1, and the causal gene identified as a new allele of Acetyl-CoA Carboxylase1 (ACC1), a gene ...

It has been known that the changes in gonadal steroids are closely associated with adipose tissue metabolism. Domestic pigs have been a well-recognized experimental animal in biomedical research because of their similarity to humans in body size and other physiological/anatomical features. The aims of this study were to investigate the influence of castration-induced sex hormone deficiency on ...
This study investigated the effects of fasting and refeeding on AMP-activated protein kinase (AMPK) and carbohydrate response element binding protein (ChREBP) mRNA, protein and activity levels; as well as the expression of lipogenic genes involved in regulating lipid synthesis in broiler chicken (Gallus gallus) liver. Fasting for 24 or 48 h produced significant declines in ...
In this work, we analysed 11 genetic markers localized on OAR11 in a commercial population of Spanish Churra sheep to detect QTL that underlie milk fatty acid (FA) composition traits. Following a daughter design, we analysed 799 ewes distributed in 15 half-sib families. Eight microsatellite markers and three novel SNPs identified in two genes related to fatty acid metabolism, ...
Perturbed prolactin (PRL) secretion and concomitant downregulation of PRL receptor (PRLR) in periparturient dams exposed to altered gravity are linked to aberrant lipogenesis and reduced neonatal survival. PRL and glucocorticoids (GC) are known to modulate PRLR expression. We hypothesized that improving levels of PRLR would mitigate the increased gravity [hypergravity (HG)]-induced effects of ...
A recombinant human genomic liver DNA [lambda]-phage library was screened with the insert of the pHuTRP-2 cDNA clone to isolate a series of bacteriophage with inserts spanning the human TYRP2 gene. One of the [lambda]-phage clones ([lambda]HuT-YRP2-7) containing a 2-kb HindIII fragment with the 5[prime] exon sequence of the cDNA as determined by sequence analysis was used for ...

The embryo to neonate transition is a critical period of development that has significant impact on broiler production. During this time important genetic programs governing metabolism and growth are established. The goal of this work was to study the effects of early post-hatch (PH) development and the time of initiation of feeding on activation of the genetic program regulating hepatic ...
BackgroundChronic systemic inflammation and abnormal free fatty acid metabolism are closely related to ectopic lipid deposition. In this study, we investigate if inflammation tissue-specifically disrupts lipogenesis and lipolysis in nonadipose tissues and adipose tissue, resulting in ectopic lipid deposition in C57BL/6J mice.MethodsWe used casein injection in C57BL/6J mice to induce a chronic ...

Acetyl-CoA carboxylase-alpha (ACCA) is a rate-limiting enzyme in long chain fatty acid synthesis, playing a critical role in cellular energy storage and lipid synthesis. ACCA is upregulated in multiple types of human cancers and small interfering RNA-mediated ACCA silencing in human breast and prostate cancer cells results in oxidative stress and apoptosis. This study reports ...
Aspects of energetic and intermediary metabolism were studied in a colon adenocarcinoma cell line (HT29) by multinuclear magnetic resonance spectroscopy. Experiments were carried out on the HT29-D4 clone, which was isolated by limit dilution techniques. This clone, usually undifferentiated (D4-UD), can be maintained in a differentiated state (D4-D) in a glucose-free medium. Metabolic data were ...
Insulin-like growth factor-1 (IGF-1) plays the role in cellular lipid synthesis and cell proliferation. However, the role of IGF-1 on the growth of colon cancer cell line HCT-8 is not clear. In this study, HCT-8 cells were exposed to IGF-1 at 0, 10, 50, or 100�ng/ml in serum-free medium. Fatty acid/lipid synthesis in HCT-8 cells was examined by 2-14C-acetate incorporation. HCT-8 cell growth and ...
