Conclusion

These data suggest that CReP abundance is a critical determinant for eIF2α phosphorylation and ensuing ISR activation in the liver. Constitutive ISR activation in the liver induces FGF21 and confers protection from HFD-induced adiposity, IR, and HS in mice. Augmenting hepatic ISR may represent a therapeutic approach to treat metabolic disorders.
