| Objective To explore the mechanism of Puerarin inhibiting osteoclast differentiation. Methods The RAW264.7 cells were induced by sRANKL+M-CSF for 7 days to differentiate into osteoclasts. MTS detected the effects of Puerarin on the proliferation of osteoclasts with different concentrations, and the effect of Puerarin on osteoclast differentiation was detected by TRAP staining. The absorptive activity of osteoclasts was detected by osteoassay surface multiple well plate, and the effects of Puerarin on the intracellular transfer and expression of the core protein p65 of NF-кB signaling pathway was detected by immunofluorescence and Western blot, respectively. Results MTS showed that Puerarin (10-8 mol/L, 3 h) significantly inhibited the proliferation of osteoclasts. Puerarin obviously inhibited the differentiation and the absorptive activity of osteoclasts, inhibited the nuclear transposition of the core protein p65, and inhibited the p65 phosphorylation. Conclusion Puerarin inhibits osteoclast differentiation through NF-кB pathway. |
