DY131

DY131 appears to inhibit Smo signaling through a common binding site shared by previously reported Smo agonists and antagonists. Sox2-Cre:Errβ+/lox and Sox2-Cre:Errβlox/lox mice treated with the Errβ and Errγ agonist DY131 demonstrated increased corticotropin-releasing hormone (Crh) expression in the paraventricular nucleus of the hypothalamus, although corticosterone levels were not affected. Adrenal Cyp11b1 and Cyp11b2 mRNA were increased in pregnant WT mice treated with DY131. In this study,using RNA knockdown and transcriptional activation with DY131 (an ERRγ agonist), we clearly demonstrated that ERRγ promotes hormone production and cell fusion indicating that ERRγ is a key positive transcriptional factor involved in CT differentiation.
