(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...

Analysis of PPAR-alpha null livers from animals treated with perfluorooctanoic acid (PFOA), a member of a class of industrial chemicals called peroxisome proliferator chemicals. PFOA exposure is linked to cancer. Results provide insight into the role of PPAR-alpha in mediating the effects of PFOA.

(Submitter supplied) Humans and ecological species have been found to have detectable body burdens of a number of perfluorinated alkyl acids (PFAA) including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). In mouse and rat liver these compounds elicit transcriptional and phenotypic effects similar to peroxisome proliferator chemicals (PPC) that work through the nuclear receptor peroxisome proliferator activated receptor alpha (PPARalpha). more...

(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) 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) Role of PPARalpha in the effects of DEHP on the hepatic expression of a selection of mouse genes related to nuclear receptor signaling. Di-(2-ethylhexyl)-phthalate (DEHP), a widely used plasticizer, is detected in consumer’s body fluids. Contamination occurs through environmental and food chain sources. In mouse liver, DEHP activates the peroxisome proliferator-activated receptor alpha (PPARalpha) and regulates the expression of its target genes. more...

(Submitter supplied) Most of the transcriptional changes induced by PFOS in the fetal mouse liver and lung were related to activation of PPARalpha. When compared to the transcript profiles induced by PFOA (Pubmed ID 17681415), few remarkable differences were found other than up-regulation of Cyp3a genes. Because PFOS and PFOA have been shown to differ in their mode of action in the murine neonate, these data suggest that changes related to PFOS-induced neonatal toxicity may not be evident in the fetal transcriptome at term.

(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) Perfluorooctanoic acid (PFOA) is a potent hepatocarcinogen and peroxisome proliferator (PP) in rodents. Humans are not susceptible to peroxisome proliferation and are thought to be refractory to carcinogenesis by PFOA and other PPs. However, previous studies with rainbow trout have shown that they are also insensitive to peroxisome proliferation by the PP, dehydroepiandrosterone (DHEA), but are still susceptible to enhanced hepatocarcinogenesis after chronic exposure. 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) 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...
