摘要：Hormone-sensitive lipase (HSL) is an intracellular neutral lipase found in a variety of tissues, primarily in adipose and steroidogenic tissues, that hydrolyzes triglycerides and cholesteryl esters. In the rat testis steady-state levels of HSL mRNA increase dramatically during sexual maturation. In addition, HSL-like immunoreactive proteins of 84, -89, and -102 kD have been observed in sexually immature rats with additional -113 and -127 kD immunoreactive proteins expressed in mature animals. In the present studies the ability of human chorionic gonadotropin (hCG) to regulate the expression of HSL and HSL-like immunoreactive proteins in rat testes has been examined. Treatment of sexually immature rats with daily injections of hCG caused a gradual increase in HSL activity that reached an 80% rise (P
