Abstract

Chinese herbal medicine Fructus Cnidii has an outstanding effect on chronic lumbar pain and impotence, also has been used against osteoporosis with high frequency. Yet, the mechanisms of osthole, a derivative of Fructus Cnidii, on osteoclasts remains barely known. In this study, it was found out that osthole (10−6mol/L, 10−5mol/L) had the influence of inhibiting osteoclast formation and bone resorptive activities induced by receptor activator of nuclear factor κB ligand (RANKL), rather than affecting the viability of osteoclast-like cells. Furthermore, osthole could also inhibit the messenger RNA expressions of c-Src, tartrate-resistant acid phosphatase, β3-Integrin, matrix metallopeptidase 9, and cathepsin K. The results of the mechanistic study indicated that osthole regulated the nuclear factor of activated T-cells cytoplasmic 1 (NFATc1) and nuclear factor-κB (NF-κB) activations following the RANKL stimulation. These findings suggested that the inhibitory effects of osthole were associated with restraining the activations of NFATc1 and NF-κB induced by RANKL. Thus osthole can be used as a potential treatment for abnormal bone-resorption related diseases.
