Abstract: PURPOSE: To study the effects of soybean isoflavoneon on osteoclastic differentiation of mandible bone marrow-derived macrophages (mBMMs). METHODS: Four-week-old female S-D rats were used to obtain mBMMs. CCK-8 assay was used to analyze the changes of cell viability of mBMMs due to different concentration of soybean isoflavoneon. The effect of soybean isoflavoneon on osteoclastic formation and osteoclastic gene expression was determined by tartrate resistant acid phosphatase staining (TRAP) and q-PCR. SPSS16.0 software package was used for data analysis. RESULTS: Cell viability of mBMMs treated with 1 μmol/L, 100 nmol/L, 10 nmol/L and 1 nmol/L soybean isoflavoneon was comparable with the control group, while100 μmol/L and10 μmol/L soybean isoflavoneon inhibited cell viability of mBMMs (P<0.05). With TRAP staining, both 1 μmol/L and 100 nmol/L soybean isoflavoneon decreased the number osteoclast in BMMs induced by RANKL (P<0.05). Moreover, the mRNA level of NFATc1, MMP9, Trap and Ctsk of in mBMMs treated with 1 μmol/L and 100 nmol/L soybean isoflavoneon decreased significantly in comparison with the control group. CONCLUSIONS: Soybean isoflavoneon inhibits osteoclastic differentiation of mBMMs.
