摘要 精子发生是一个复杂而又精确的生殖细胞分化的过程,它经历了精原细胞有丝分裂、精母细胞减数分裂和精子形成3个阶段。这一过程受许多因素的调控,其中细胞周期蛋白的调节起着决定性作用。细胞周期蛋白通过与相应的细胞周期蛋白依赖激酶结合形成具有蛋白激酶活性的异源二聚体复合物,磷酸化多种蛋白,推动细胞周期各时相的有序进行。近年来研究发现,细胞周期蛋白A、B、D、E在精子发生的调控中扮演着重要角色,本文综述了这4种细胞周期蛋白在调控精子发生中的作用。 Spermatogenesis is a complex and precise process of differentiation of germ cells, which involves three stages: mitosis of spermatogonia, meiosis of spermatocytes and formation of spermatozoa. The process is controlled by many factors, including regulation of cyclins in spermatogenic cells, which plays a pivotal role. Cyclins form heterologous dimer compounds with protein kinase activity by binding to cyclin-dependent kinases, then phosphorylate multiple proteins and promote the orderly conduct of each phase of the cell cycle. In recent years, cyclins A, B, D and E have been found to play important roles in the regulation of spermatogenesis. This article presents an overview on the roles of these four cyclins in regulating the progression of spermatogenesis.
