چکیده انگلیسی
Tenuigenin, a major active component of polygala tenuifolia root, has been used to treat patients with insomnia, dementia, and neurosis. In this study, we aimed to investigate the effects of tenuigenin on osteoclastogenesis and clarify the possible mechanism. We showed that tenuigenin inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation and bone resorption without cytotoxicity, which was further demonstrated by reduced osteoclast specific gene expression such as TRAP, c-Src, ATP6v0d2, etc. Moreover, the inhibitory effect of tenuigenin was associated with impaired NF-κB activity owing to delayed degradation/regeneration of IkBa and inhibition of p65 nuclear translocation. Consistent with the in vitro results, micro-ct scanning and analysis data showed that tenuigenin suppressed RANKL-induced bone loss in an animal model. Taken together, our data demonstrate that tenuigenin inhibit osteoclast formation and bone resorption both in vitro and in vivo, and comprise a potential therapeutic alternative for osteoclast-related disorders such as osteoporosis and cancer-induced bone destruction.
