Rattus norvegicus | several negative feedback loops within the liver and small intestine down-regulate Cyp7a1 transcription to prevent accumulation of bile acids to toxic levels. The the JNK/c-Jun pathway is involved in downregulation of Cyp7a1, overview | down |
Rattus norvegicus | rodent Cyp7a1 expression increases in response to cholesterol-enriched diets, resulting in increased bile acid synthesis | up |
General Information | Comment | Organism |
---|---|---|
metabolism | cholesterol 7alpha-hydroxylase, Cyp7a1, catalyzes the rate-limiting step of the classical pathway of bile acid synthesis and is the major mechanism for cholesterol catabolism and removal from the body. Cyp7a1 regulation, detailed overview | Rattus norvegicus |
physiological function | regulation of Cyp7a1 expression is critical for maintenance of cholesterol and bile acid homeostasis | Rattus norvegicus |
