(Submitter supplied) Pregnane X receptor (PXR), a xenobiotic receptor involved in drug metabolism, has been reported to regulate lipid and glucose metabolism. The intestine tract is the first inner barrier of the body, which dysfunction contributes to the development of metabolic disorders. However, the role of intestinal PXR in metabolic diseases remains largely unknown. In this study, we showed that activation of PXR by tributyl citrate (TBC), an intestinal-selective agonist of PXR, improved high fat diet (HFD)-induced obesity and insulin resistance. more...

(Submitter supplied) Growing evidence suggests that chemicals in disparate structural classes activate specific subsets of PPARγ’s transcriptional programs to generate adipocytes with distinct phenotypes. Our objectives were to 1) establish a novel classification method to predict PPARγ-interacting and modifying chemicals and 2) create taxonomy labels to group chemicals based on their effects on PPARγ’s transcriptome and downstream metabolic functions. more...

(Submitter supplied) In this study we examined transcriptional responses to 29 ToxCast chemicals in dose-response format. The chemicals were selected because in vitro transcriptional effects could be extrapolated to in vivo effects including liver cancer and steatosis incidences using in vitro to in vivo extrapolation.

(Submitter supplied) The mice were treated i.p. with pregnenolone-16-α-carbonitrile (PCN, 50mg/kg dissolved in DMSO-corn oil 1:3) or vehicle (DMSO-corn oil 1:3) once daily for four days. The mice were fasted for four hours and then administered glucose (2g/kg) by oral gavage or further kept on fasting. The mice were sacrificed 1 hour after glucose administration.

(Submitter supplied) RCCHanTM:WIST male rats were administered for 7 days by oral gavage with vehicle (corn oil) or 100 mg/kg/day of pregnenolone-16α-carbonitrile(PCN). We used microarrays to evaluate gene expression profiling in rat liver at the early phase of treatment with PCN.

(Submitter supplied) Changes in gene expression were assayed in mouse liver nuclear RNA following a single injection of the CAR agonist TCPOBOP (1,4-Bis-[2-(3,5-dichloropyridyloxy)]benzene) or the PXR agonist PCN (pregnenolone 16α-carbonitrile) in 7-week old mice. This study is part of a larger study entitled Sex-Differential Responses of Tumor Promotion-Associated Genes and Dysregulation of Novel Long Noncoding RNAs in Constitutive Androstane Receptor-Activated Mouse Liver (PMID: 28903501).

(Submitter supplied) Liver tumors in rodents are frequently induced by non-genotoxic carcinogens. These hepatocarcinogens generally activate hepatic nuclear receptors (e.g., CAR and PXR), resulting in a cascade of signals causing modifications in the expression of genes responsible for several processes involved in carcinogenesis. Evaluation of the carcinogenic potential of chemicals is a regulatory requirement but is time-consuming and expensive. more...

(Submitter supplied) TCPOBOP (1,4-bis[2-(3,5-dichloropyridyloxy)]benzene) and PCN (pregnenolone 16α-carbonitrile) are inducers of drug metabolism through activation of nuclear receptors CAR (constitutive androstane receptor) and PXR (pregnane X receptor), respectively. Mouse experiment was designed to study the effect of CAR and PXR activation on cholesterol homeostasis genes and other genes, which are present on the Steroltalk v2 microarray. more...

(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...
