项目摘要
The role of Wnt5a-Ror2 signals in osteoclast function was studied. (1) Bone-resorbing activities of osteoclasts derived from Wnt5a-deficient mice and from Ror2 deficient mice were lower than that of wild-type(WT) osteoclasts. (2) Wnt5a activated Rho, a small G protein, in WT osteoclasts but not in Ror2-deficient osteoclasts. (3) When active Rho was transfected into Ror2-deficient osteoclasts, the bone-resorbing activity was recovered. Thus, Wnt5a-Ror2 signals play important roles in osteoclast function through a Rho-dependent mechanism.
研究了WNT5A-ROR2信号在破骨细胞功能中的作用。 (1)源自Wnt5a缺陷小鼠和ROR2缺乏小鼠的破骨细胞的骨骼抑制活性低于野生型(WT)破骨细胞。 (2)Wnt5a在WT破骨细胞中激活了一种小的G蛋白Rho,但在ROR2缺乏的破骨细胞中没有激活Rho。 (3)当主动Rho转染到ROR2缺陷骨细胞中时,恢复了骨呈现活性。因此,Wnt5A-ROR2信号通过RHO依赖性机制在破骨细胞功能中起重要作用。
