The 66 KDa isoform of Shc and its signalling properties have attracted in the past years major interest in aging research. Here, we summarize p66Shc functions and outline a specific signalling route leading to mitochondrial import, that accounts for its pro-apoptotic activity upon oxidative stress. This model, that could explain the alterations of mitochondrial Ca2+ homeostasis observed after oxidative stress, highlights novel pharmacological targets in age-related disorders.
过去几年，Shc的66千道尔顿同工型及其信号传导特性在衰老研究中引起了极大关注。在此，我们总结了p66Shc的功能，并概述了一条导致线粒体导入的特定信号通路，该通路解释了其在氧化应激时的促凋亡活性。这个模型可以解释氧化应激后观察到的线粒体钙稳态改变，突出了与年龄相关疾病中的新药物靶点。
