Research Abstract

We revealed that PPARγ regulates several genes involved in histone lysine methyltransferase genes thereby regulates adipogenesis. We also revealed that the mechanism by which Wnt/β-catenin inhibits adipogenesis. Wnt/β-catenin stimulates COUP-TFII gene expressions, whose gene product inhibits PPARγ2 gene expression through the recruitment of HDAC to the transcription regulatory region of PPARγ2.
