Transcriptional regulation of mouse L-Pgds gene in adipocyte 3T3-L1 cells (Fujimori et al., 2007a). L-Pgds gene expression is activated by liver receptor homolog-1 (LRH-1), one of orphan nuclear receptors, through the LRH-responsive element (LRH-RE) in pre-adipocytes. In the differentiated adipocytes, activation of liver X receptor (LXR) elevates the expression of sterol regulatory element-binding protein-1 (SREBP-1c) through the LXR-responsive element (LXRE), and then SREBP-1c strongly enhances the L-Pgds gene expression via two sterol regulatory elements (SREs) in the promoter region of L-Pgds gene.
