半胱天冬酶是通过蛋白水解级联协调细胞破坏来执行细胞凋亡的核心。半胱天冬酶介导的蛋白水解还控制多种非致死性细胞活动,如增殖、分化、细胞命运决定和细胞骨架重组。在过去的十年左右,果蝇的遗传学研究有助于我们了解在体内机制的非凋亡细胞的反应,在发展的背景下。此外,最近的研究使用C。elegans的研究表明,凋亡信号可能发挥意想不到的作用,在生物体水平上影响衰老和正常发育。在这篇综述中,我们描述了caspase活性是如何精心控制在重要的细胞过程中的亚细胞定位的水平,持续时间和时间,以避免完全凋亡的后果,也讨论了新的作用,非凋亡caspase信号在成人的稳态和生理。
Caspases are at the core of executing apoptosis by orchestrating cellular destruction with proteolytic cascades. Caspase-mediated proteolysis also controls diverse nonlethal cellular activities such as proliferation, differentiation, cell fate decision, and cytoskeletal reorganization. During the last decade or so, genetic studies of Drosophila have contributed to our understanding of the in vivo mechanism of the non-apoptotic cellular responses in developmental contexts. Furthermore, recent studies using C. elegans suggest that apoptotic signaling may play unexpected roles, which influence ageing and normal development at the organism level. In this review, we describe how the caspase activity is elaborately controlled during vital cellular processes at the level of subcellular localization, the duration and timing to avoid full apoptotic consequences, and also discuss the novel roles of non-apoptotic caspase signaling in adult homeostasis and physiology.
