Webexample, the PERK pathway of the UPR is part of the integrated stress response that consists of three other eIF2a kinases [1]. Activation of any of these kinases leads to eIF2a phosphorylation and induction of ATF4 and CHOP [1]. A recent study also showed that ATF4 and CHOP can be regulated translationally in WebJul 24, 2024 · The results showed that HMGB1 challenge increased both PERK/eIF2a/ATF4 pathway protein levels (p-PERK/PERK, p-eIF2a/eIF2a, and ATF4) and apoptotic marker protein levels (CHOP and c-Caspase 3/Caspase 3), which were attenuated by the anti-RAGE Ab (Fig. 6A, B). Moreover, the A549 cell apoptosis rate was significantly higher in the …
