Sasp and hypoxia
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 ]. WebbUnder hypoxic conditions, the hypoxia inducible factor 1-alpha (HIF-1α)-mediated upregulation of the glycolytic pathway, coupled with the downregulation of PDH, induces …

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. Webb2 mars 2024 · The secretion of SASP causes a variety of extracellular reactions, in which inflammation is the most important one. Accordingly, the interaction between the immune system and cellular senescence provides a new direction for the diagnosis and treatment of age-related diseases.
