[Regulation of fat metabolism by PPARs].

Peroxisome proliferator activated receptors (PPARs) belong to the nuclear receptor superfamily. PPARs have diverse biological functions such as enhancing insulin sensitivity, regulating saccharometabolism homeostasis, and especially regulation of lipid homeostasis, which is the focus of much of the researches at present. In this article, we summarize the regulation of fat metabolism by PPAR genes based on their structure, function and expression.
