Elevated proteasome activity extends lifespan in model organisms such as yeast, worms and flies. This pro-longevity effect might be mediated by improved protein homeostasis, as this protease is an integral module of the protein homeostasis network. Proteasomes also regulate cellular processes through temporal and spatial degradation of signaling pathway(More)
Recent studies on the effect of aging in epidermal cells have evidenced a decrease of proteasome activity and content, suggesting that proteasome is down-regulated in aged cells. The 20S proteasome is the major proteolytic system that has been implicated in removal of abnormal and oxidatively damaged proteins. Therefore, a decreased proteasome content may(More)
