Abstract

LH acutely increases luteal progestin biosynthesis by stimulating cholesterol side-chain cleavage, a reaction catalyzed by a complex of mitochondrial enzymes containing cytochrome P-450 (1). The steroidogenic action of LH is inhibited by cycloheximide and puromycin, indicating a requirement for protein synthesis (2). It has been suggested that availability of cholesterol governs the rate of side-chain cleavage and that proteins formed under the influence of LH play a role in translocation of cholesterol to the mitochondrial enzyme complex (1,2). In the present study, relationships between cholesterol supply and in vitro steroid synthesis by rat luteal mitochondria were explored.
