Effect of dietary fat and cholesterol on hepatic gene expression of liver-specific Cyp51 knockout male and female mice

Cholesterol is one of the key molecules in mammals and the most striking examples of its deficiency are the inborn errors of cholesterol biosynthesis that manifest in severe whole body phenotypes. Liver, the principal site of cholesterol homeostasis, has rarely been investigated in these defects. We thus focused on the hepatocyte-specific deletion of lanosterol 14-demethylase (CYP51) catalyzing the rate-limiting step in the post-squalene part of cholesterol synthesis.
