Notoginsenoside R1 attenuates oxidative stress‐induced osteoblast dysfunction through JNK signalling pathway

Oxidative stress (OS)-induced mitochondrial damage and the subsequent osteoblast dysfunction contributes to the initiation and progression of osteoporosis. Notoginsenoside R1 (NGR1), isolated from Panax notoginseng, has potent antioxidant effects and has been widely used in traditional Chinese medicine. This study aimed to investigate the protective property and mechanism of NGR1 on oxidative-damaged osteoblast. Osteoblastic MC3T3-E1 cells were...
