WebThe 7-AB treatment also triggered endoplasmic reticulum (ER) stress, leading to activation of the PERK/elF2α/ATF4/CHOP apoptotic pathway. Furthermore, 7-AB initiated autophagy in NCI-N87 cells and induced the expression of autophagy-related proteins, including Atg3, Atg5, Atg7, Atg12, LC3-I, and LC3-II. WebApr 13, 2014 · The activated PERK phosphorylates the elF2α (eukaryotic translation initiation factor 2α), inhibiting translation and resulting in cell cycle arrest. CHOP (C/EBP homology protein) is downstream of PERK–elF2α–ATF4 and regulates apoptotic mitochondrial protein Bcl-2 (Stacchiotti et al. 2013 ).
WebJan 20, 2024 · Xu et al. (2024) showed that miR-451a overexpression activates apoptosis by inducing PERK/elF2α/ATF4/CHOP signaling in colorectal cancer cells, HCT116, and SW620. On the contrary, Huang et al. (2016) showed that ER stress-mediated induction miR-663 stimulates cell proliferation and reduces apoptosis in hepatocellular carcinoma cell. WebMar 24, 2024 · Pretreatment with mitochondria-targeted antioxidant Mito-TEMPO alters the Rh1-reduced rate of mito- and glycol-ATP. Furthermore, Rh1 induces ER stress-mediated calcium accumulation via PERK/eIF2α/ATF4/CHOP pathway. Inhibition of ATF4 by siRNA transfection significantly inhibited Rh1-mediated apoptosis and calcium production.
