DNA损伤剂和辐射、细胞毒素和抗癌药物、端粒侵蚀和细胞因子、培养冲击和有丝分裂刺激、癌基因和肿瘤抑制因子都能诱导细胞周期停滞和细胞衰老。由于这种半重合性,衰老与细胞周期停滞相混淆,或者更具误导性的是,与生长抑制相混淆。由于存在这些误解,细胞衰老无法与机体衰老联系起来。而且,癌症与衰老之间的关系也被扭曲。在此我将讨论为什么停滞与衰老之间的联系是半重合的,以及衰老如何与衰老和癌症相关。
DNA damaging agents and radiation, cytotoxins and anti-cancer drugs, telomere erosion and cytokines, culture shock and mitogenic stimuli, oncogenes and tumor suppressors can induce both cell cycle arrest and cellular senescence. Due to this semi-coincidence, senescence is confused with cell cycle arrest, or even more misleadingly, with growth inhibition. With such misconceptions, cellular senescence cannot be linked to organismal aging. Also, the relation between cancer and senescence is distorted. Here I discuss why the link between arrest and senescence is semi-coincidental and how senescence is related to aging and cancer.
