ABSTRACT
Aim To investigate the molecular mecha-nism for the inhibitory effect of puerarin on IL-6 secre-tion in human osteoblast-likeMG-63 cells. Methods According to our previous studies, human osteoblast-like MG-63 cells containing two estrogen receptor ( ER) isoforms are a suitable model for this study. En-zyme-linked immnosorbent assay (ELISA), RT-PCR, luciferase reporter assay and small interfering RNA were performed to investigate the effect of puerarin on IL-6 expression in osteoblast-derived cells and underly-ing molecular mechanism. Results Puerarin could obviously inhibit IL-6 expression and IL-6 promoter ac-tivity by human osteoblastic MG-63 cells. Treatment with the ER antagonist ICI 182,780 abrogates the a-bove actions of puerarin on osteoblast-derived cells. U-sing siRNA technology, we further demonstrated that the effects of puerarin on IL-6 production were media-ted by ERα. Conclusion The effect of puerarin on IL-6 production in osteoblast is mediated by ERα.
