Reactive oxygen species, such as superoxide, hydrogen peroxide, and lipid peroxides, impair luteal function. Vitamin E, a lipophilic antioxidant vitamin, provides a major avenue of protection by scavenging free radicals and terminating lipid peroxidation. We previously showed that ovarian vitamin

Barrier perturbation stimulates epidermal cholesterol synthesis, which plays an important role in restoring barrier function. In the present study, we examined whether changes in serum cholesterol levels or nutrition regulate epidermal cholesterol synthesis in hairless mice. Serum cholesterol levels were

This study was performed to investigate the effects of 17 alpha-ethinyl estradiol, a potent hypocholesterolemic agent at pharmacological doses, on cholesterol balance in the liver and extrahepatic tissues of the rat in vivo. Female Sprague-Dawley rats were treated with 17
These studies were done to examine the effect of gonadotropin on rat luteal 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase activity (the rate-limiting step in cholesterol biosynthesis) in ovaries of pregnant mare's serum gonadotropin (PMSG)-human chorionic gonadotropin (hCG) primed rats. Administration

Prolonged (7-day) hCG infusion caused a remarkable hypertrophy of rat Leydig cells, coupled with a notable enhancement of their basal and stimulated testosterone production in vitro. It also provoked a conspicuous accumulation of lipid droplets in the cytoplasm of hypertrophic
