Abstract:
The p66Shc gene has emerged as a novel gerontogene affecting health and life during aging. In murine models of aging,a genetic deficiency of the p66Shc gene,which encodes a phosphotyrosine signal adapter protein,extends life span by 30%. p66Shc is a crucial regulator of reactive oxygen species levels and is involved in age-related dysfunctions. UP to now,oxidative stress has been recognized to be involved in human diseases such as high cholesterol,diabetes,and cardiovascular diseases. Further study on the role of p66Shc will facilitate the research of novel disease-targetted drugs and slow down or cure age-related pathologies.
