Fat and Beyond: The Diverse Biology of PPARγ

The nuclear receptor PPARγ is a ligand-activated transcription factor that plays an important role in the control of gene expression linked to a variety of physiological processes. PPARγ was initially characterized as the master regulator for the development of adipose cells. Ligands for PPARγ include naturally occurring fatty acids and the thiazolidinedione (TZD) class of antidiabetic drugs. Activation of PPARγ improves insulin sensitivity in...
