项目摘要
In present study, I investigated the osteoclast inhibition ability in CS and the mechanism how CS inhibit osteoclast differentiation in vitro. CS was significantly inhibited the number of tartrate-resistance acid phosphatase (TRAP)-positive multinucleated cells and bone resorption activity in pit formation assay.In quartz-crystal microbalance method, CS revealed the binding ability to RANKL and interrupted binding of RANK to RANKL. Furthermore, CS reduced the phosphorylation of extracellular ERK in pre-osteoclast cells. These results indicate that CS suppress osteoclast size and osteoclastogenesis by binding to RANKL and inhibited RANK signal pathway.
在本研究中,我研究了CS对破骨细胞的抑制能力以及CS在体外抑制破骨细胞分化的机制。在小坑形成实验中,CS显着抑制抗酒石酸酸性磷酸酶(TRAP)阳性多核细胞的数量和骨吸收活性。在石英晶体微天平法中,CS显示出与RANKL的结合能力并中断RANK与RANKL的结合。此外,CS 还能降低前破骨细胞中细胞外 ERK 的磷酸化。这些结果表明CS通过与RANKL结合并抑制RANK信号通路来抑制破骨细胞大小和破骨细胞生成。
