The cell cycle is regulated in part by cyclins and their associated serine/threonine cyclin-dependent kinases, or CDKs. CDK4, in conjunction with the D-type cyclins, mediates progression through the G1 phase when the cell prepares to initiate DNA synthesis. Although CDK4-null mutant mice are viable and cell proliferation is not significantly affected in vitro due to compensatory roles played by other CDKs, this gene plays a key role in mammalian development and cancer. This review discusses the role that CDK4 plays in cell cycle control, normal development, and tumorigenesis as well as how small molecule inhibitors of CDK4 can be used to treat disease.
细胞周期部分受细胞周期蛋白及其相关的丝氨酸/苏氨酸细胞周期蛋白依赖性激酶(即CDK)调控。CDK4与D型细胞周期蛋白共同作用,在细胞准备启动DNA合成时介导细胞通过G1期。尽管CDK4基因敲除的突变小鼠能够存活,且由于其他CDK发挥的补偿作用,细胞增殖在体外未受到显著影响,但该基因在哺乳动物发育和癌症中起着关键作用。本文综述了CDK4在细胞周期调控、正常发育和肿瘤发生中的作用,以及CDK4小分子抑制剂如何用于治疗疾病。
