Er stress mediated apoptosis

WebMoreover, during ER stress, the level of CHOP expression is elevated, and CHOP functions to trigger mitochondria-mediated apoptosis by downregulating the prosurvival protein Bcl-2 . Given the effects of compound 275# on the induction of ROS, apoptosis activation in response to compound 275# was evaluated. WebSep 9, 2024 · The activation of apoptosis pathways mediated by the ER stress-mitochondrial cascade may be a crucial mechanism of EC apoptosis (Figure 1). Under ER stress, it was found that CHOP-mediated imbalance of the Bcl-2 family activated proapoptotic proteins on the mitochondrial membrane, inducing cytochrome c release …
