Schematic diagram of signal-transduction network during ER stress-induced cell apoptosis. Apoptotic signals are transduced through ATF6-, IRE1- and PERK-governed signaling pathways in ER stress-induced apoptosis. This diagram mainly showed PERK-associated pathways, whereas ATF6- and IRE1-regulated pathways are briefly demonstrated. According to previous studies, in ER stress-induced apoptosis, PERK/eIF2α/ATF4, PERK/CaN, PERK/eIF2α/TDAG51, PERK/eIF2α/IAP2 and PERK/NRF2 pathways are considered PERK-associated
