摘要
Previous studies suggest that Akt signaling promotes tissue regeneration and decreased Akt activities are found in aged tissues. However, this study finds that the expression and activation levels of Akt in the mice skin increased with age. Additionally, the expression levels of Pten, p16, p21 and p53 also elevated with increased age. Immuno-fluorescence analysis showed that Akt phosphorylation found in the epidermal cells (with increased levels of NF-kappa B activation) were also found. In vivo inhibition of AKT activity result in reduced NF-kappa B activation. Our results suggest that increasing Akt/NF-kappa B is a crucial mediator of skin aging, which can increase the susceptibility of cell transformation.
