参与骨关节炎的P38丝裂原活化蛋白激酶信号转导通路

摘要

BACKGROUND: p38 mitogen-activated protein kinase signal transduction pathway is a member of the mitogen-activated protein kinase family. It plays an important role in the development of osteoarthritis. OBJECTIVE: To review the progress of p38 mitogen-activated protein kinase signal transduction pathway in the pathological process of osteoarthritis. METHODS: An online search of CNKI and PubMed databases was performed for articles using keywords of “p38 mitogen-activated protein kinase signal transduction pathway, osteoarthritis, articular cartilage, chondrocyte” in Chinese and English, respectively. Relevant articles were summarized from three aspects of introduction of p38 signal transduction pathway, the role of p38 mitogen-activated protein kinase signal transduction pathway in osteoarthritis and the inhibitor of p38 in osteoarthritis. A total of 90 articles were included. According to inclusion criteria, a number of 46 articles were retained at last. RESULES AND CONCLUSION: p38 mitogen-activated protein kinase signal transduction pathway has a close relation with chondrocyte hypertrophy and calcification, chondrocyte apoptosis, synthesis of cartilage matrix metal oproteinase, production of proinflammatory cytokines, and exerts a significant effect on the development of osteoarthritis. p38 mitogen-activated protein kinase is involved in the formation and development of osteoarthritis through a variety of complex mechanisms and plays a very important role. Therefore, blocking p38 mitogen-activated protein kinase signaling pathway may be a new target in the treatment of osteoarthritis.%　　背景：p38丝裂原活化蛋白激酶信号转导通路属于丝裂原活化蛋白激酶家族成员，在骨关节炎的发生发展中发挥重要作用。目的：对骨关节炎病理进程中 p38丝裂原活化蛋白激酶信号转导通路相关作用机制的研究进展进行综述。方法：由第一作者用计算机检索中国期刊全文数据库和 PubMed 数据库，检索词分别为“p38丝裂原活化蛋白激酶信号通路、骨关节炎、关节软骨、软骨细胞”和“p38MAPK signal transduction pathway, osteoarthritis, Articular cartilage，Chondrocyte”。从 p38丝裂原活化蛋白激酶信号通路简介，p38丝裂原活化蛋白激酶在骨关节炎中的作用，p38丝裂原活化蛋白激酶阻断剂在骨关节炎中的应用3方面进行总结。共检索到可应用文献90篇，按纳入标准对文献进行筛选，共纳入46篇文章。结果与结论：p38丝裂原活化蛋白激酶信号通路与软骨细胞的肥大化和钙化、软骨细胞的凋亡、软骨基质金属蛋白酶的合成、软骨炎性细胞因子的产生等有密切关系，对骨关节炎的发生发展有重要影响。p38丝裂原活化蛋白激酶通过多种复杂的机制参与骨关节炎的形成和发展，对其起到极其重要的作用，因此阻断 p38丝裂原活化蛋白激酶信号通路可能成为骨关节炎治疗的新靶点。
