Webb24 aug. 2016 · SASP is a common (but not unique) phenotype in the cells exposed to oxidative, replicative and genotoxic stress as well as telomere shortening and oncogenic mutations. Just ectopic expression or activation of CDK inhibitors (e.g., p16, p21) can also result in SASP [ 17 ]. WebbThe SASP and its factors, such as Pai1, TGF-β1, IL-1β, IL-6, and others, reinforce senescence (autocrine senescence) and propagate senescence throughout the retina (paracrine senescence). Eventually, the SASP hinders vascular regeneration of the ischemic retina and contributes to pathological preretinal angiogenesis.
