Cellular senescence occurs in response to diverse stresses (e.g., telomere shortening, DNA damage, oxidative stress, oncogene activation). A growing body of evidence indicates that alterations in multiple components of endocytic pathways contribute to cellular senescence. Clathrin-mediated endocytosis (CME) and caveolae-mediated endocytosis (CavME) represent major types of endocytosis that are implicated in senescence. More recent research has also identified a chromatin modifier and tumor suppressor that contributes to the induction of senescence via altered endocytosis. Here, molecular regulators of aberrant endocytosis-induced senescence are reviewed and discussed in the context of their capacity to serve as senescence-inducing stressors or modifiers.
细胞衰老发生于对多种应激的反应中(例如端粒缩短、DNA 损伤、氧化应激、致癌基因激活)。越来越多的证据表明,内吞途径的多个组成部分的改变会导致细胞衰老。网格蛋白介导的内吞作用(CME)和小窝蛋白介导的内吞作用(CavME)是内吞作用的两种主要形式,与衰老有关。最近的研究还发现了一种染色质修饰因子和肿瘤抑制因子,它通过改变内吞作用促进衰老的发生。在这里,我们综述了异常内吞作用诱导衰老的分子调控因子,并讨论了它们作为诱导衰老的应激因子或修饰因子的能力。
