(Submitter supplied) Unlike the PPARalpha agonist W14,643, PFOA is capable of inducing effects independently of PPARa. Genes altered in the PPARalpha-null mouse following exposure to PFOA included those associated with fatty acid metabolism, inflammation, xenobiotic metabolism, and cell cycle progression. The specific signaling pathway(s) responsible for these effects is not readily apparent but it is conceivable that other members of the nuclear receptor superfamily such as PPARbeta/delta and CAR may be involved. more...

(Submitter supplied) Exposure to PFOA during gestation altered the expression of genes related to fatty acid catabolism in both the fetal liver and lung. In the fetal liver, the effects of PFOA were robust and also included genes associated with lipid transport, ketogenesis, glucose metabolism, lipoprotein metabolism, cholesterol biosynthesis, steroid metabolism, bile acid biosynthesis, phospholipid metabolism, retinol metabolism, proteosome activation, and inflammation. more...

(Submitter supplied) Toxicogenomic Dissection of the Perfluorooctanoic Acid (PFOA) Transcript Profile in Mouse Liver: Evidence for the Involvement of Nuclear Receptors PPARalpha and CAR We performed a toxicogenomics dissection of the transcript profiles in the mouse liver after exposure to PFOA. We uncovered classes of genes that were regulated independently of PPARalpha. Some of these genes, including those involved in lipid metabolism, may be regulated by PPARbeta/delta or PPARgamma, whereas others, such as those involved in xenobiotic metabolism are likely regulated through CAR. more...

(Submitter supplied) We reported the hepatic gene expression profiling in mice treated by perfluorooctanoate (PFOA) and high fat diet (HFD). Chronic HFD treatment was associated with gene expression changes in cholesterol biosynthetic process, lipid metabolic process, extracellular matrix, and inflammatory response pathways. Many chemokine related genes including Ccl2, Ccr2, Ccl3l3, Cx3cl1, Cx3cr1, Cxcl14, and toll-like receptor (TLR) related genes including Tlr2, Tlr7, Tlr8, Tlr13 were all significant upregulated comparing vehicle-treated HFD-fed mice to control diet (CD)-fed mice, suggesting their roles in the development of steatohepatitis. more...

(Submitter supplied) Perfluorooctane sulfonate (PFOS) is a perfluoroalkyl acid (PFAA) and a persistent environmental contaminant found in the tissues of humans and wildlife. Although blood levels of PFOS have begun to decline, health concerns remain because of the long half-life of PFOS in humans. Like other PFAAs, such as perfluorooctanoic acid (PFOA), PFOS is an activator of peroxisome proliferator-activated receptor-alpha (PPARα) and exhibits hepatocarcinogenic potential in rodents. more...

(Submitter supplied) Fatty acids comprise the primary energy source for the heart and are mainly taken up via hydrolysis of circulating triglyceride-rich lipoproteins. While most of the fatty acids entering the cardiomyocyte are oxidized, a small portion is involved in altering gene transcription to modulate cardiometabolic functions. So far, no in vivo model has been developed enabling study of the transcriptional effects of specific fatty acids in the intact heart. more...

(Submitter supplied) The nuclear receptor peroxisome proliferator-activated receptor alpha (PPARα) regulates responses to chemical or physical stress in part by altering expression of genes involved in proteome maintenance. Many of these genes are also transcriptionally regulated by heat shock (HS) through activation by HS factor-1 (HSF1). We hypothesized that there are interactions on a genetic level between PPARα and the HS response mediated by HSF1. more...

(Submitter supplied) Perfluoroalkyl substances (PFAS) are man-made chemicals with suspected endocrine-disrupting properties. Exposure to perfluorooctanoic acid (PFOA) has been linked to disturbed metabolism via the liver, although the exact mechanism is not clear. Moreover, information on the metabolic effects of the new PFAS alternative GenX is limited. We tested whether low-dose exposure to PFOA and GenX induces metabolic disturbances, including NAFLD, dyslipidemia, and glucose tolerance in mice and studied the involvement of PPARα. more...

(Submitter supplied) Background: The selective absorption of nutrients and other food constituents in the small intestine is mediated by a group of transport proteins and metabolic enzymes, often collectively called ‘intestinal barrier proteins’. An important receptor that mediates the effects of dietary lipids on gene expression is the peroxisome proliferator-activated receptor alpha (PPARα), which is abundantly expressed in enterocytes. more...
