Mouse organic solute transporter α deficiency enhances renal excretion of bile acids and attenuates cholestasis
Carol J. Soroka, Albert Mennone, Lee R. Hagey, Nazzareno Ballatori, James L. Boyer – 23 December 2009 – Organic solute transporter alpha‐beta (Ostα‐Ostβ) is a heteromeric bile acid and sterol transporter that facilitates the enterohepatic and renal‐hepatic circulation of bile acids. Hepatic expression of this basolateral membrane protein is increased in cholestasis, presumably to facilitate removal of toxic bile acids from the liver. In this study, we show that the cholestatic phenotype induced by common bile duct ligation (BDL) is reduced in mice genetically deficient in Ostα.
