Dehydroepiandrosterone (DHEA) is the only known naturally occurring compound that promotes peroxisome proliferation in rodent liver, and stimulates transcriptional induction of genes involved in lipid metabolism and peroxisomal beta-oxidation. Therefore, we examined mRNA for several such genes in rat liver, specifically acyl-CoA oxidase and the cytochromes P-450 (CYP4A1, CYP4A3, and CYP3A23), a...
BACKGROUND Differentiation of pluripotent human embryonic stem cells (hESCs) to the cardiac lineage represents a potentially unlimited source of ventricular cardiomyocytes (VCMs), but hESC-VCMs are developmentally immature. Previous attempts to profile hESC-VCMs primarily relied on transcriptomic approaches, but the global proteome has not been examined. Furthermore, most hESC-CM studies focus ...
background : peroxisome proliferator-activated receptor gamma (ppar γ) is a transcription factor, which is abundantly expressed in adipose tissue and has a direct link to adiposity. it seems that long-chain polyunsaturated fatty acids (lc-pufas) can regulate ppar γ expression. the purpose of this study was to investigate the effects of n-3lc pufa supplementation on plasma levels of ppar γ and t...
Several contaminants detected in aquatic ecosystems are agonists of peroxisome proliferator-activated receptors (PPARs). Peroxisome proliferator-activated receptors interact with the retinoid X receptor (RXR) to activate the transcription of genes that control a variety of physiological functions. We cloned and sequenced partial cDNA fragments of rainbow trout (Oncorhynchus mykiss) PPARalpha an...
OBJECTIVE We tested the hypothesis that endothelial peroxisome proliferator-activated receptor-γ protects against vascular thrombosis using a transgenic mouse model expressing a peroxisome proliferator-activated receptor-γ mutant (E-V290M) selectively in endothelium. APPROACH AND RESULTS The time to occlusive thrombosis of the carotid artery was significantly shortened in E-V290M mice compare...
OBJECTIVE To investigate whether high-density lipoproteins (HDLs) suppress chemokine (CCL2, CCL5, and CX(3)CL1) and chemokine receptor (CCR2 and CX(3)CR1) expression, a mechanism for the atheroprotective properties of HDLs. METHODS AND RESULTS Apolipoprotein (apo) E(-/-) mice were fed a high-fat diet for 12 weeks. Before being euthanized, the mice received 5 consecutive daily injections of li...
Peroxisome proliferator activated receptor(alpha) (PPARalpha) mediates the liver's responses to peroxisome proliferator compounds. These responses include induction of specific hepatic enzymes, peroxisome proliferation and hepatocyte proliferation. PPARalpha null mice, which lack receptor in all cells of the body, do not respond to peroxisome proliferators, indicating that hepatocellular prolif...
Fibroblast growth factor 21 (FGF21) is an atypical member of the FGF family that functions as an endocrine hormone. Pharmacologic studies show that FGF21 has broad metabolic actions in obese rodents and primates that include enhancing insulin sensitivity, decreasing triglyceride concentrations, and causing weight loss. In lean rodents, FGF21 expression is strongly induced in liver by prolonged ...
