Liver X receptor a (LXRa) plays a critical role in the maintenance of energy homeostasis within a cell through tight transcriptional regulation of genes involved in metabolism of lipids, glucose, and cholesterol. Although LXRa has been established to function as a heterodimer with the retinoid X receptor a (RXRa), recent studies have determined that LXRa also interacts directly with peroxisome proliferator-activated receptor a (PPARa). However, little is known regarding the functionality of this heterodimer, if any exists at all. This study determined that a heterodimer of PPARa and LXRa is capable of binding to candidate response elements in vitro with …
