WebWe find that cyclic GMP-AMP synthase (cGAS) recognizes cytosolic chromatin fragments in senescent cells. The activation of cGAS, in turn, triggers the production of …
Autolysosomal degradation of cytosolic chromatin …
WebHere, using NIH3T3 cells exposed to hydrogen peroxide stress, we show that stress-induced DNA damage provokes the SASP largely via cytosolic chromatin fragment (CCF) formation, which activates a cascade … WebWithin the cytoplasm, cGAS binds to chromatin fragments harboring DSBs and activates innate immune signaling, which often leads to premature senescence. Thus, cGAS recognizes cytosolic chromatin fragments generated in response to dysfunctional telomeres, and that triggers premature senescence independently of telomere … cyber monday deals snowboard gear
