WebThe activity of the C. elegans gene ced-9 is required to protect cells that normally survive from undergoing programmed cell death [4]. Overexpression of bcl-2 can mimic the protective effect of ced-9 on C. elegans cell death and can prevent the ectopic cell deaths that occur in ced-9 loss-of-function mutants [4]. Web麻省理工学院的Robert Horvitz 领导的研究小组采用体细胞突变的方法发现共有14 个基因在C. elegans细胞凋亡中起作用，其中在细胞凋亡的实施阶段起作用的主要有3个：Ced-3、Ced-4和Ced-9，其中Ced-3和Ced-4的作用是诱发凋亡，在缺乏Ced-3、Ced-4的突变体中不发生凋亡，有 ...
