Abstract: Objective:?To explore the protective effect of Res on BMSCs under oxidative stress in vitro. Methods:? Rat BMSCs were treated with 200 μmol/L hydrogen peroxide to undergo oxidative stress. CCK8, ROS fluorescent probe, qRT-PCR, Western blot and ALP staining examined the effects of different concentration of Res on the cell viability, intracellular ROS levels, osteogenic differentiation and ferroptosis in rat BMSCs under oxidative stress. Results:?Res between 1 and 25 μmol/L promoted the cell viability of rat BMSCs stimulated by hydrogen peroxide (P<0.05). 10 μmol/L Res significantly reduced the ROS levels of hydrogen peroxide -stimulated rat BMSCs and increased the expression of antioxidant-related genes, such as NRF2, CAT, SOD-1 and SOD-2 (P<0.05). 10 μmol/L Res promoted the expression of osteogenic-related markers of hydrogen peroxide -stimulated rat BMSCs (P<0.05), significantly enhanced the ALP staining effect, promoted the expression of ferroptosis-related markers (GPX4, XCT) (P<0.05), decreased the expression of acyl-CoA synthetase long-chain family member(ACSL4), prostaglandin-endoperoxide synthase 2 (PTGS2) and nuclear receptor coactivator 4 (NCOA4) (P<0.05). Conclusions:?Res could reduce the level of ROS and ferroptosis of oxidative stress-induced rat BMSCs, maintain the cell viability and promote the osteogenic differentiation of rat BMSCs under oxidative stress.
