摘要
背景:研究表明,Wnt信号通路参与调节骨髓间充质干细胞向成骨细胞分化,促进成骨细胞增殖和分化,抑制成骨细胞的程序性死亡,间接影响破骨细胞的功能。目的:分析Wnt/β-连环蛋白信号通路与骨疾病的关系。方法:通过计算机检索CNKI和Elsevier数据库中2000年1月至2014年1月文献,关键词为"Wnt/β-连环蛋白、成骨细胞、骨髓间充质干细胞、骨质疏松,骨关节炎"。选择与Wnt/β-连环蛋白信号通路对成骨细胞及骨疾病影响有关的文章内容进行归纳分析。结果与结论:Wnt信号通路包括Wnt/β-连环蛋白信号通路(Wnt经典信号通路);Wnt/Ca2+信号通路;Wnt/PCP(平面细胞极性)信号通路等。Wnt信号途径是体内重要的信号调节系统之一,对成骨细胞、破骨细胞和软骨细胞的分化、增殖和程序性死亡过程中扮演重要角色。在类风湿关节炎患者体内Wnt信号途径主要通过成骨细胞发挥作用。其成骨细胞中Wnt信号途径的抑制因子上调,能够降低骨保护素/受体活化因子配体比值,促进破骨细胞分化成熟。研究Wnt通路的组分及其作用,不仅有助于骨疾病的特定治疗,而且有利于预防骨质疏松及其他关节性等疾病。
BACKGROUND：Wnt signal pathway is involved in the regulation of bone marrow mesenchymal stem cells differentiating into osteoblasts, promotes osteoblasts proliferation and differentiation, inhibits programmed death of osteoblasts, and indirectly affects the function of osteoclasts. OBJECTIVE：To summarize the relationship between Wnt/β-catenin signal pathway and bone disease. METHODS：A computer-based online search was performed to find papers published between January 2000 and January 2014 in CNKI database and Elsevier database. The key words were“Wnt/β-catenin, osteoblasts, bone marrow mesenchymal stem cells, osteoarthritis, chondrocytes”in Chinese. Documents concerning the effects of Wnt/β-catenin signal pathway on osteoblasts and bone disease were included. RESULTS AND CONCLUSION：Wnt signaling pathway is consisted of Wnt/β-catenin signal pathway （Wnt typical signal pathway）, Wnt/Ca2＋signal pathway and Wnt/planar cellpolarity signal pathway. Wnt signaling pathway is one of the most important regulatory systems that plays a key role in modulating the differentiation, proliferation and programmed celldeath of osteoblasts, osteoclasts and chondrocytes. The role of Wnt signal pathway in patients with rheumatoid arthritis is mediated by osteoblasts. The inhibitory factor of Wnt signal pathway in osteoblasts is upregulated, which reduces the ratio of osteoprotegerin/receptor activating factor ligand, promotes the osteoclasts differentiation and immaturation. The researches addressing the components and effect of Wnt signal pathway are important for the special treatment of bone diseases and the prevention of osteoporosis or other bone diseases.
