Abstract

Objectives : This study was performed to evaluate the effect of Securinega suffructicosa Rehder (SS) on osteoclast differentiation and gene expression. Methods : The osteoclastogenesis and gene expression were determined in RANKL-stimulated RAW 264.7. The results were summarized as followes. Results : SS decreased the number of TRAP positive cell in RANKL-stimulated RAW264.7 cell. SS decreased the expression of RANK, TNF${\alpha}$, and IL-6 in RANKL-stimulated RAW264.7 cell. SS decreased the expression of iNOS and COX-2 in RANKL-stimulated RAW264.7 cell. SS decreased the expression of Cathepsin K in RANKL-stimulated RAW264.7 cell. Conclusions : It is concluded that SS might decrease the bone resorption resulted from decrease of osteoclast differentiation and it's related gene expression.
