Abstract

To investigate the effect of osthole on bone metabolism in rat femoral tissues in vitro.The rat femoral tissues were isolated in vitro. The optimal concentrations of ostehole (1×10(-5) mol/L) and estradiol (1×10(-8) mol/L) (the positive control) were selected by alkaline phosphatase activity (ALP). The ALP and calcium levels were detected by commmerical regents, and the expressions of osteoprotegerin, receptor activator of nuclear factor-κB ligand, runx-related gene 2, and bone morphogenetic protein-2 mRNA were determined by real-time reverse transcription-polymerase chain reaction.The osthole (1×10(-5) mol/L) significantly increased the activity of ALP, calcium level as well as the expressions of osteoprotegerin, receptor activator of nuclear factor-κB ligand, runx-related gene-2 and bone morphogenetic protein-2 mRNA in rat femoral tissues in vitro.Osthole can improve calcium level and ALP activity and regulate the bone metabolism-related genes in rat femoral tissues.
