Abstract: BACKGROUND: The pathogenesis of osteoporosis is complex, and its essence is the weakening of bone formation and the enhancement of bone absorption caused by various reasons, resulting in the imbalance of bone metabolism. In recent years, N6-methyladenosine has been found(N6-methyladenosine, m6A) methylation can prevent and treat osteoporosis by regulating bone metabolism.
OBJECTIVE: Taking the regulation of bone metabolism by m6A methylation as an entry point, to systematically sort out and summarize the research progress of m6A methylation in osteoporosis, so as to provide certain theoretical reference bases for the search of new therapeutic targets for osteoporosis. 
METHODS: CNKI, WanFang, VIP, PubMed, MEDLINE, Nature, and Cochrane databases were retrieved for relevant literature published from database inception to 2023. The keywords were “osteoporosis, m6A methylation, bone metabolism, bone marrow mesenchymal stem cells, osteoblasts, osteoclasts” in Chinese and English. Duplicates and obsolete non-referenced documents were excluded, and a total of 73 standard papers were included for further review.
RESULTS AND CONCLUSION: m6A methylation can affect the activity and differentiation of bone marrow mesenchymal stem cells, osteoblasts, and osteoclasts through various pathways to regulate bone metabolism and prevent osteoporosis. The regulatory process of m6A methylation is extremely complex, and its related proteins play different roles in different cells. Even in the same kind of cells, the same type of proteins may have radically different roles, regulating different physiological and pathological processes.

Key words: m6A methylation, bone metabolism, osteoporosis, bone marrow mesenchymal stem cell, osteoblast, osteoclast, research progress
