In conclusion, we demonstrate that treatment with dulaglutide, a GLP-1 receptor agonist, could recover muscle strength, muscle mass, and muscle fiber size, which were reduced during immobilization. Dulaglutide treatment attenuated the induction of atrophic genes, such as those encoding MuRF-1, atrogin-1, and myostatin, and enhanced MHC expression. In addition, dulaglutide treatment inhibited the expression of inflammatory cytokines and apoptotic genes through the induction of heat shock protein 72 (Hsp72) expression via AMPK activation, contributing to the amelioration of disuse-induced muscle atrophy.
