We have used primary monolayer cultures of rat hepatocytes to study the effects of physiological concentrations of various bile acids, commonly found in bile of normal rats, on the mechanism of regulation of cholesterol 7 alpha-hydroxylase and bile acid synthesis. Addition of taurocholic acid, the most predominant bile acid in rat bile, to the culture medium suppressed cholesterol 7 alpha-hydroxylase activity and mRNA time- and dose-dependently. The decrease in enzyme activity paralleled the… CONTINUE READING
