Global hepatic gene expression data from PPARa liver KO, PPARa liver WT, PPARaKO and WT male mice treated or not with Fenofibrate

Project description:Fenofibrate is a specific agonist of the nuclear receptor PPARa. To identify the gene expression under the strict dependence of hepatic PPARa activity, we generated a new mouse strain of PPARa-specific deletion in hepatocyte (albumin-Cre+/- Pparaflox/flox or LKO) and we compared them to total Ppara KO (KO), wild-type (WT) and liver WT (albumin-Cre-/- Pparaflox/flox or LWT) mice. We used microarrays to detail the global programme of gene expression in liver of Ppara LKO, LWT, Ppara KO and WT male mice. There are 36 liver samples, each from an individual mouse. The samples are from Ppara liver KO (LKO), Ppara KO (KO), wild-type (WT) and liver WT (LWT) male mice of 14 week-old from the same genetic background (C57Bl/6J) treated with Fenofibrate (100 mg/kg/day) or vehicle (aqueous solution of gum Arabic 3%) by daily gavage for 10 days. n= 4 mice for LKO, LWT and WT genotypes treated with vehicle; n=3 for KO mice treated with vehicle; n=5 mice for LWT, LKO and KO genotypes treated with fenofibrate; n=4 WT mice treated with fenofibrate. All mice were sacrified at ZT14.

The effect of PPARa siRNA on endothelial cells treated with fenofibrate

Project description:Fenofibrate is a synthetic ligand for the nuclear receptor peroxisome proliferator-activated receptor (PPAR) alpha, but there are reports that fenofibrate affects endothelial cells in PPARa-independent manner. In order to identify PPARa-dependently and PPARa-independently regulated transcripts we generated microarray data from human endothelial cells treated with fenofibrate with and without siRNA-mediated knock-down of PPARa. In this study, we generated microarray data from human umbilical vein endothelial cells (HUVECs) treated with fenofibrate with pretreatment PPARa or control siRNA. There are four time points (4, 8, 12 and 18hours) (n=1 at each time point).

Gene repression through epigenetic modulation by PPARA enhances hepatocellular proliferation

Project description:Peroxisome proliferator-activated receptor α (PPARA) is a key mediator of lipid metabolism and inflammation. Activation of PPARA in rodents causes hepatocyte proliferation, but the underlying mechanism is poorly understood. This study focused on genes repressed by PPARA and analyzed the mechanism by which PPARA promotes hepatocyte proliferation in mice. Activation of PPARA by agonist treatment was autoregulated, and induced expression of the epigenetic regulator UHRF1 via activation of the newly described PPARA target gene E2f8, that in turn regulates Uhrf1. UHRF1 strongly repressed expression of CDH1 via methylation of the Cdh1 promoter marked with H3K9me3. Repression of CDH1 by PPARA activation was reversed by PPARA deficiency or knockdown of E2F8 or UHRF1. Furthermore, forced expression of CDH1 inhibited expression of the Wnt signaling target genes such as Myc after PPARA activation, and suppressed hepatocyte hyperproliferation. These results demonstrate that the PPARA-E2F8-UHRF1-CDH1 axis causes epigenetic regulation of hepatocyte proliferation. This SuperSeries is composed of the SubSeries listed below.
