title: [Study of HDL2-dependent synthesis of bile acids in culture of rabbit hepatocytes: effects of oxidized cholesterol derivatives].
abstract: The effect of individual oxysterols--products of auto-oxidation of cholesterol on bile acid synthesis by cultivated rabbit hepatocytes was studied. Relative rates of bile acid synthesis were measured as the conversion of 4-14C cholesterol-HDL2 into total 4-14C labeled bile acids. 7 beta-hydroxycholesterol and 3,5-cholestane-7-dione strongly inhibited bile acid synthesis at concentrations 1-10 micrograms/ml. These data support the hypothesis that oxidized cholesterol derivatives accelerate the development of hypercholesterolemia in rabbits fed on cholesterol containing diet.
