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 proapoptotic 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.

Abstract
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 proapoptotic 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.File in questo prodotto:
