Liver receptor homolog 1 transcriptionally regulates human bile salt export pump expression
12 Feb 2008
Abstract excerpt
The metabolic conversion of cholesterol into bile acids in liver is initiated by the rate-limiting cholesterol 7 alpha-hydroxylase (CYP7A1), whereas the bile salt export pump (BSEP) is responsible for the canalicular secretion of bile acids. Liver receptor homolog 1 (LRH-1) is a key transcriptional factor required for the hepatic expression of CYP7A1. We hypothesized that LRH-1 was also involved in the...
