title: ESTRONE INHIBITION OF CHOLESTEROL BIOSYNTHESIS AT THE MEVALONIC ACID STAGE.
abstract: Studies on the synthesis of cholesterol with cell-free homogenates of liver from rats treated with graded doses of estrone show that, at doses of estrone which cause a reduction in blood cholesterol, there is an accompanying inhibition of cholesterol biosynthesis. Furthermore, this inhibition appears to occur at the stage of cholesterol biosynthesis at which mevalonate is decarboxylated.
