metformin alleviates drug-induced osteoarthritis (OA)-like change in mice knee joint through activating autophagy and downregulating apoptosis. Metformin exerts its protective effects against OA through the AMPKa2/ SIRT1 pathway. Metformin suppresses IL-1β-induced oxidative and osteoarthritis-like inflammatory changes by enhancing the SIRT3/PINK1/Parkin signaling pathway, thereby indicating metformin's potential in prevention and treatment of osteoarthritic joint disease.
