英文摘要

Icariin, a principal flavonoid glycoside in Herba Epimedii, is hypothesized to possess beneficial effects on bone mass. Icariin is metabolized to icariside 11 and then to icaritin in vivo. In the present study, we investigated the in vitro effects of icariin, icariside 11 and icaritin on both osteoblasts and osteoclasts. After treatment with these compounds at concentrations 10(-5)-10(-8) mol/l, ostcoblasts were examined for proliferation, alkaline phosphatase activity, osteocalcin secretion and matrix mineralization, as well as expression levels of bone-related proteins. The formation of osteoclasts was assessed by counting the number of multinucleated TRAP-positive cells. The activity of isolated rat osteoclasts was evaluated by measuring pit area, actin rings and superoxide generation. Icariside 11 and icaritin increased the mRNA expression of ALP, OC, COL-1 and OPG, but suppressed that of RANKL. In addition, these compounds reduced the number of multinucleated TRAP-positive cells and the osteoclastic resorption area. Also decreases were observed in superoxide generation and actin ring formation that are required for osteoclast survival and bone resorption activity. These findings suggest that icaritin, which was more potent than icariin and icariside 11, enhanced the differentiation and proliferation of osteoblasts, and facilitated matrix calcification; meanwhile it inhibited osteoclastic differentiation in both osteoblast-preosteoclast coculture and osteoclast progenitor cell culture, and reduced the motility and bone resorption activity of isolated osteoclasts.
