OPRM1 and chronic atrophic gastritis: In addition, the protective effects on the liver and kidney are mediated by regulating lipid metabolism, inflammation, apoptosis, autophagy, and oxidative stress via the AGE/AGER, LXR/ApoE/ABCA1, mTOR, Bax/Bcl-2, caspase-3/9, Nrf2/HO-1, and iNOS/Cox-2 pathways; Mor also promotes hair growth by increasing β-catenin and improves chronic atrophic gastritis and colitis by inhibiting inflammation and apoptosis.; Moreover, Mor increases flap survival, promotes wound healing, and promotes hair growth.
