چکیده انگلیسی
Oxidative stress can induce apoptosis and decrease activities of osteoblasts. 2,3,5,4â²-tetrahydroxystilbene-2-O-β-d-glucoside (TSG), is a potent antioxidant derived from a Chinese herb Polygonum multiflorum Thunb. To evaluate the protective effect provided by TSG to osteoblastic MC3T3-E1 cells, the cells were pretreated with TSG for 24 h before being treated with 0.3 mM hydrogen peroxide (H2O2) for 24 h, then some markers of osteoblast function and oxidative damage of the cells were examined. Our data demonstrated that TSG significantly (P< 0.05) increased cell survival, alkaline phosphatase (ALP) activity, calcium deposition, and the mRNA expression of ALP, collagen I (COL-I) and osteocalcin (OCN) in the presence of H2O2. In addition, TSG decreased the production of receptor activator of nuclear factor-κB ligand (RANKL), interleukin-6 (IL-6), intracellular reactive oxygen species and malondialdehyde (MDA) of osteoblastic MC3T3-E1 cells induced by H2O2. Taken together, these results demonstrated that the protective effect provided by TSG to osteoblastic MC3T3-E1 cells was mediated, at least in part, via inhibition of the release of bone-resorbing mediators and oxidative damage of the cells. Our results indicated that TSG may be effective in providing protection against osteoporosis associated with oxidative stress.
