(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) Fipronil (CAS #: 120068-37-3), a widely used insecticide, has been described as a thyroid disruptor in rat inducing a marked increase in thyroxine (T4) clearance resulting in a decrease in T4 plasma concentration. These effects seem to require the bioactivation of fipronil via its biotransformation into fipronil sulfone by cytochromes P450 (CYP). Here, we hypothesized that fipronil-induced thyroid disruption may, at least in part, result from the induction of hepatic enzymes involved in the metabolism of thyroid hormones. more...

(Submitter supplied) To identify the CAR-, PXR- and PPARα-specific genome-wide expression changes, hepatocyte cultures from six individual donors were treated with the prototypical ligands for CAR (CITCO), PXR (rifampicin) and PPARα (WY14,643) as well as DMSO (vehicle control). Afterwards, the mRNA expression in these samples was determined utilizing Affymetrix® microarrays.

(Submitter supplied) The nuclear receptor PXR (Pregnane X rreceptor) mediates the effects of pregnenolone-16alpha-carbonitrile (PCN) on gene transcription. The relative role of PXR and also CAR to the induction response by PCN was studied on cDNA arrays containing 320 (Steroltalk V2) genes (genes involved in cyrcadian rhythm, drug metabolism, cholesterol biosynthesis, sterol synthesis/transport, heme synthesis). Samples from livers of wild type and CAR-/-, PXR-/- or CAR/PXR-/- knockout mice were tested after treatment with PCN for gene expression within the European Framework V program “Steroltalk” (www.steroltalk.net). more...

(Submitter supplied) Unfiltered coffee markedly increases serum lipid levels in humans and mice. The responsible compounds are the fat-soluble diterpenes cafestol and kahweol. Cafestol is responsible for more than 80% of the effect on serum lipids and is the most potent cholesterol-elevating compound known in the human diet. Aim of these microarray studies was to identify novel genes and regulatory pathways determining the cholesterol raising effect of cafestol by genome-wide expression studies. more...

(Submitter supplied) Activation of the pregnane X receptor (NR1I2) by drugs and other xenobiotics stimulates (or suppresses) expression of numerous genes involved in the metabolic elimination of foreign compounds and some toxic endogenous substrates. We used microarray analysis to identify genes whose expression in rat liver was significantly altered by pregnenolone 16alpha-carbonitrile (PCN) treatment.
