Webknockout animals that PERK and ATF6 as well as IRE1 are required for the full activation of the UPR (14, 17–19). PERK, ATF6, and IRE1 have common features as UPR induc-ers. Nevertheless, there are several differences among their func-is essential for the viability of exocrine and endocrine pancreatic cells (20). WebDec 26, 2024 · IRE1α, IRE1β, ATF6α and ATF6β are ubiquitously expressed in medaka. We found that IRE1α/ATF6α-double knockout is lethal, similarly to IRE1α/IRE1β- and ATF6α/ATF6β-double knockout. Therefore, IRE1 inhibitors are expected to confer lethality to ATF6α-knockout medaka but not to wild-type medaka.
WebSep 29, 2009 · We also used a conditional knockout strategy to demonstrate that IRE1 α-deficient embryos supplied with functionally normal placentas can be born alive. Fetal liver hypoplasia thought to be responsible for the embryonic lethality of IRE1 α-null mice was virtually absent in rescued IRE1 α-null pups.
