细胞周期停滞还不是衰老。当细胞周期停滞时,不适当的生长促进会将停滞转变为衰老(衰老转化)。通过抑制促进生长的mTOR通路,雷帕霉素可减缓停滞细胞的衰老转化。举一个显著的例子,p53在导致停滞的同时,可能会减缓或抑制衰老转化(在某些情况下)。在此,我讨论衰老转化的含义,以及衰老基因、衰老抑制因子、抗衰老药物、致衰老通路、衰老促进因子、功能亢进和反馈抵抗、再生潜能、肥大和继发性萎缩、促衰老细胞和致衰老细胞等术语。
Cell cycle arrest is not yet senescence. When the cell cycle is arrested, an inappropriate growth-promotion converts an arrest into senescence (geroconversion). By inhibiting the growth-promoting mTOR pathway, rapamycin decelerates geroconversion of the arrested cells. And as a striking example, while causing arrest, p53 may decelerate or suppress geroconversion (in some conditions). Here I discuss the meaning of geroconversion and also the terms gerogenes, gerossuppressors, gerosuppressants, gerogenic pathways, gero-promoters, hyperfunction and feedback resistance, regenerative potential, hypertrophy and secondary atrophy, pro-gerogenic and gerogenic cells.
