与普遍观点不同,分子损伤的累积在衰老过程中并不起关键作用。然而,癌症(一种与年龄相关的疾病)是由分子损伤引发的。癌症和衰老有很多共同之处,包括TOR通路的激活。但是分子损伤的作用将癌症和衰老区分开来。此外,对损伤和衰老在癌症中所起作用的分析反驳了“由分子损伤累积导致的衰退”是衰老的原因这一观点。我还讨论了随机的分子损伤如何通过多轮增殖和选择,导致癌症的非随机性特征。
Despite common belief, accumulation of molecular damage does not play a key role in aging. Still, cancer (an age-related disease) is initiated by molecular damage. Cancer and aging share a lot in common including the activation of the TOR pathway. But the role of molecular damage distinguishes cancer and aging. Furthermore, an analysis of the role of both damage and aging in cancer argues against “a decline, caused by accumulation of molecular damage” as a cause of aging. I also discuss how random molecular damage, via rounds of multiplication and selection, brings about non-random hallmarks of cancer.
