Web24. mar 2024 · The PERK-ATF4 pathway plays a primary role in inducing CHOP transcription (Fels and Koumenis, 2006). When ERS expression is excessive, the upstream regulatory sequence of the 5′ terminal that contains an open reading frame gene becomes activated, which inhibits eIF2α-dependent protein translation ( Schröder and Kaufman, 2005 ) and ... WebIn hypoxic conditions, TRIB3 induction was found to be dependent on the PERK/ATF4/CHOP pathway and depletion of TRIB3 reduced cell survival under hypoxic conditions [65]. …
