Bile Acid Homeostasis in a Cholesterol 7α‐Hydroxylase and Sterol 27‐Hydroxylase Double Knockout Mouse Model

Guo – 12 March 2019 – Bile acids (BAs) are diverse molecules that are synthesized from cholesterol in the liver. The synthesis of BAs has traditionally been shown to occur through two pathways. Cholesterol 7α‐hydroxylase (CYP7A1) performs the initial and rate‐limiting step in the classical pathway, and sterol 27‐hydroxylase (CYP27A1) initiates the hydroxylation of cholesterol in the alternative pathway.
