Abstract: BACKGROUND: Osteoarthritis is pathologically characterized by progressive degeneration of the articular cartilage and abnormal deformation of the subchondral bone. In recent years, with the deepening of medical research, it has been found that the mitogen-activated protein kinases (MAPK) signaling pathway has a regulatory role in inflammatory cell infiltration, inflammatory factor release, and chondrocyte proliferation, which is particularly important for the treatment of osteoarthritis.
OBJECTIVE: To briefly review the main research progress in the mechanism of MAPK signaling pathway regulating osteoarthritis in recent years, aiming to provide new ideas for the treatment of osteoarthritis.
METHODS: CNKI, WanFang and PubMed databases were searched for relevant literature using the search terms of “mitogen-activated protein kinases, osteoarthritis, extracellular signal-regulated MAP kinases, p38 mitogen-activated protein kinases, JNK mitogen-activated protein kinase” in Chinese and English. Relevant literature published from January 2019 to November 2024 was searched, and 108 articles were finally included for summary analysis.
RESULTS AND CONCLUSION: (1) Various stimuli inside and outside the cells activate the MAPK signaling pathway, regulate gene transcription and protein synthesis, and promote the release of inflammatory factors, such as tumor necrosis factor-α, interleukin-1β, and interleukin-6. The release of these inflammatory factors aggravates the progression of osteoarthritis. (2) The active ingredients of traditional Chinese medicine, mainly saponins and flavonoids, as well as Chinese herbal formulas and preparations with the main effects of activating blood circulation and removing blood stasis, tonifying the liver and kidney, can play a therapeutic role in osteoarthritis by inhibiting the MAPK signaling pathway, regulating the release of matrix metalloproteinases, balancing the homeostatic state of osteogenesis and osteoblastogenesis, attenuating the synovial inflammation, decreasing the release of inflammatory factors and inflammatory vesicles, decreasing cellular pyroptosis, promoting autophagy, and ameliorating oxidative stress. (3) Although traditional Chinese medicine has become popular in the treatment of osteoarthritis by virtue of its own advantages of multi-components, multi-targets, multi-pathways, and low side effects, the use of MAPK signaling pathway to guide the treatment of individual osteoarthritis is the difficulty of the technology, which needs to be continuously researched and explored. (4) Therefore, further development of relevant herbal inhibitors that can modulate the MAPK signaling pathway may be a potential drug strategy for the treatment of osteoarthritis in the future.
