Project description:Sterol regulatory element-binding protein 2 (SREBP2) is a transcription factor that has been recently discovered to mediate vascular endothelial cell (EC) dysfunction. We therefore investigated the role of SREBP2 in EC function through comparing the transciptional profiling of human umbilical vein endothelial cells (HUVECs) that were infected with adenovirus overexpressing SREBP2 (Ad-SREBP2) or with empty vector (Ad-null) control. Gene ontology analysis revealed that SREBP2 not only regulates cholesterol biosynthesis, but also mediates the TGF, WNT, and cytoskeleton remodeling pathways. Among the responsive genes, SREBP2 exhibited the induction of mesenchymal transition.
Project description:Sterol regulatory element-binding protein 2 (SREBP2) is a transcription factor that has been recently discovered to mediate vascular endothelial cell (EC) dysfunction. We therefore investigated the role of SREBP2 in the epigenetic function of EC biology through comparing ATAC-seq of human umbilical vein endothelial cells (HUVECs) that were infected with adenovirus overexpressing SREBP2 (Ad-SREBP2) or with empty vector (Ad-null) control. Gene ontology analysis revealed that SREBP2 not only decondenses chromatin for cholesterol biosynthesis, but also mediates the TGF pathway. Among the responsive promoter, SREBP2 exhibited the induction of genes related to mesenchymal transition.
