Abstract

Cell cycle exit is required for terminal differentiation of many cell types. The retinoblastoma protein Rb has been implicated both in cell cycle exit and differentiation in several tissues. Rb is negatively regulated by cyclin-dependent kinases (Cdks). The main effectors that down-regulate Cdk activity to activate Rb are not known in the lens or other tissues. In this study, using multiple mutant mice, we show that the Cdk inhibitors p27(KIP1) and p57(KIP2) function redundantly to control cell cycle exit and differentiation of lens fiber cells and placental trophoblasts. These studies demonstrate that p27(KIP1) and p57(KIP2) are critical terminal effectors of signal transduction pathways that control cell differentiation.

摘要

细胞周期退出是许多细胞类型终末分化所必需的。视网膜母细胞瘤蛋白Rb在几种组织的细胞周期退出和分化过程中都发挥了作用。Rb受到细胞周期蛋白依赖性激酶(Cdks)的负调控。在晶状体或其他组织中,下调Cdk活性以激活Rb的主要效应分子尚不清楚。在本研究中,我们使用多种突变小鼠,证明细胞周期蛋白依赖性激酶抑制剂p27(KIP1)和p57(KIP2)发挥冗余功能,以控制晶状体纤维细胞和胎盘滋养层细胞的细胞周期退出和分化。这些研究表明,p27(KIP1)和p57(KIP2)是控制细胞分化的信号转导途径的关键终末效应分子。
