Abstract

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 metalloproteinase, 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.
