Lipoprotein cholesterol uptake mediates upregulation of bile acid synthesis by increasing cholesterol 7a-hydroxylase but not sterol 27- hydroxylase gene expression in cultured rat hepatocytes.

, 1999
Lipoproteins may supply substrate for the formation of bile acids, and the amount of hepatic cholesterol can regulate bile-acid synthesis and increase cholesterol 7α-hydroxylase expression.

917-96 In Vitro Inhibition of Smooth Muscle Cell Proliferation by Sterol 27-Hydroxylase Metabolites [PDF]

, 1995
Sterol 27-hydroxylase controls side chain oxidation of bile acids and is found in vascular endothelial cells. Two metabolites of this oxidation are 27-hydroxycholesterol (27-OH), which inhibits smooth muscle cell (SMC) proliferation in vivo, and 3β ...
