Abstract
Background Osteoclasts are multinucleated bone-resorbing cells that differentiate in response to receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL). Enhanced osteoclastogenesis contributes to bone diseases, such as osteoporosis and rheumatoid arthritis. Rubus parvifolius L. is traditionally used as an herbal medicine for rheumatism; however, its detailed chemical composition and the molecular mechanisms responsible for its biological action have not been elucidated. Purpose To investigate the mechanisms by which R. parvifolius L. extract and its major constituent sanguiin H-6, inhibit osteoclastogenesis and bone resorption. Methods Cell proliferation, cell differentiation, and bone resorption were detected in vitro. Inhibition of signaling pathways, marker protein expression, and protein nuclear translocation were evaluated by western blot analysis. Tumor necrosis factor-α (TNF-α)-mediated osteoclastogenesis was examined in vivo. Results R. parvifolius L. extract inhibited the bone-resorption activity of osteoclasts. In addition, sanguiin H-6 markedly inhibited RANKL-induced osteoclast differentiation and bone resorption, reduced reactive oxygen species production, and inhibited the phosphorylation of inhibitor of NF-κB alpha (IκBα) and p38 mitogen-activated protein kinase. Sanguiin H-6 also decreased the protein levels of nuclear factor of activated T cells cytoplasmic-1 (NFATc1), cathepsin K, and c-Src. Moreover, sanguiin H-6 inhibited the nuclear translocation of NFATc1, c-Fos, and NF-κB in vitro, as well as TNF-α-mediated osteoclastogenesis in vivo. Conclusions Our data revealed that R. parvifolius L. has anti-bone resorption activity and suggest that its constituent, sanguiin H-6, can potentially be used for the prevention and treatment of bone diseases associated with excessive osteoclast formation and subsequent bone destruction.
