摘要 自噬是一种细胞内降解机制,除了参与胞内蛋白和细胞器的质与量控制外,也被认为是一种与凋亡、坏死并列的程序性细胞死亡机制。然而,已揭示的自噬与凋亡、坏死的关系暗示它可能是死亡程序的管理者,在应激时细胞死亡是否发生及死亡机制的选择等过程中扮演着重要角色。自噬分子机制的揭示有助于理解这两个看似矛盾的观点。自噬在程序性细胞死亡中作用的阐明对包括肿瘤在内疾病的治疗具有重要的现实意义。 Autophagy is a degradation mechanism involved in quality and quantity control of cytoplasmic proteins and organelles,regarded as a programmed cell death juxtaposed with apoptosis and necrosis.Unravelled correlations between autophagy,apoptosis and necrosis,however,suggest that autophagy may be a manager of programme cell death,and determine whether cell death occurs and selection of death pathways in response to stress.Revealing molecular mechanism of autophagy contributes to understand these seemingly contradictory views.Elucidation of autophagy′s role in programmed cell death has important practical significance for treating tumor.
