【求助】什么是growth arrest

丁香园论坛

1104
growth arrest就是cell cycle arrest 吗?
狭指可以吧!呵
growth arrest:Protein involved in growth arrest, a phenomenon occurring when a cell does not proceed through the cell cycle.为生长阻滞;生长停滞;生长停止。是指不管用什么办法使细胞生长阻滞。而文献见得最多的就是像wild-type p53 protein 等蛋白可以有此作用。
但是cell cycle arrest :The process by which the cell cycle is halted during one of the normal phases (G1, S, G2, M).比较限定于对于G1, S, G2, M几个期。
总的来说,个人认为growth arrest是一个泛指,而cell cycle arrest 是一个相当小的概念。为了让你搞清楚,推荐一篇PNAS的老文章:Growth arrest induced by wild-type p53 protein blocks cells prior to or near the restriction point in late G1 phase请看后一起分享,我也想搞清楚。

从题目来看:growth arrest意指cell cycle arrest.

细胞生长抑制,英文表达我看得最多的是"growth inhibition or growth suppression".

growth arrest至于最准确的意思还得回到原文。

zhujoker看来对分子生物学的知识了解的比较全面,对我的几个求助帖都有不少的帮助,十分感谢。我赞同你的观点:growth arrest是一个泛指,而cell cycle arrest 是一个相当小的概念。
