Abstract: AIM To analyze the effects of α-mangostin on the proliferation and apoptosis of osteoarthritis (OA) chondrocytes.METHODS Human OA chondrocytes were isolated and then treated with 5,10 or 20 μmol/L α-mangostin.24,48 or 72 h after the treatment,the cell proliferation was measured by MTT assay,and the cell apoptosis was detected by flow cytometry.The expression check on MMP-1,MMP-3,MMP-13,PPARγ,PPARδ,PGC-lα and TNF-α was accomplished by Western blot.The contents of collagen-Ⅱ,PG,IL-1β and IL-6 were tested by ELISA.RESULTS α-Mangostin significantly induced cell proliferation and suppressed cell apoptosis,and it significantly increased the production of collagen-Ⅱ and PG,decreased the expressions of MMP-1,MMP-3 and MMP-13,induced the expressions of PPARγ,PPARδ and PGC-1α,and decreased the expression of TNF-α.Furthermore,α-mangostin significantly inhibited the production of IL-1β and IL-6.CONCLUSION α-Mangostin attenuates the destruction and degradation of cartilago articularis by inducing OA chondrocytes proliferation,inhibiting cell apoptosis and inflammation,and increasing expressions of PPARγand PPARδ.
