Project description:This SuperSeries is composed of the following subset Series: GSE15482: The effect of PPARa siRNA on endothelial cells treated with fenofibrate GSE15483: The effect of fenofibrate on endothelial cells Refer to individual Series
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 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).

In this study, we generated microarray data from human umbilical vein endothelial cells (HUVECs) treated with fenofibrate. Time 0 indicates the start point of observation immediately prior to exposure to the 25umol fenofibrate. There are five time points (2, 4, 6, 8, and 18hours) (n=3 at each time point). The control is untreatment HUVEC (n=4).
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.
Project description:Effect of TNF-alpha on microRNAs levels in Human Umbilical Endothelial Cells (HUVECs). HUVEC that were treated or not for 2 or 24 hours with TNF (10 ng/ml). Duplicate samples (1 or 2) of two different isolations of HUVEC (A or B)
