- Description
SHC1 encodes three splice variants: p46, p52, and p66. In an initial longevity study, mice double-mutants for p66 were shown to live 30% longer though it is not clear whether they age slower [6]. Additionally, the p66 mutants display an increased cognitive performance, lower emotionality and a higher pain threshold, in addition to increased basal levels of BDNF in the hippocampus, as well as decreased levels of oxidative stress markers [3626]. However, in a second study the longevity extension could not be replicated and the authors found that the knockout of Shc1 does not increase median or maximum lifespan in mice [3547]. Although the exact functions of SHC1 remain unknown, it appears to play a role in the regulation of intra-cellular redox levels, signal transduction, and apoptosis [7]. p66 mutant mice have been shown to have reduced oxidative stress and mitochondrial apoptosis. In TERC knockout mice, which normally show accelerated aging, inactivation of p66 rescues sterility and weight loss, as well as organ atrophy. However, there is no impact on shortened lifespan or telomere erosion [4354]. p66/SHC1 depletion in mice stimulates brown fat (a key thermogenic tissue) activity, resulting in a higher insulin-dependent glucose uptake and a higher energy expenditure. Additionally, brown adipose tissue cells exhibit increased mitochondrial respiration, increased expression of several mitochondrial and lipid-oxidative enzymes, which may be the cause for the improved metabolism of SHC1-deficient mice [3625]. Studies in humans have so far failed to associate polymorphisms in the SHC1 gene with ageing or longevity [231].
