Proteasome inhibition induces a senescence-like phenotype in primary human fibroblasts cultures.

Abstract excerpt

Senescent human fibroblasts exhibit several genetic and biochemical differences as compared to their young counterparts including abnormalities of the main proteolytic mechanism, namely the proteasome. Specifically, we and others have shown that there is an impaired function of the proteasome, as senescent cells have reduced proteolytic activities and less proteasome content. In a complementary work we have...
