Abstract: BACKGROUND: Research has shown that both m6A methylation modification and steroid-induced osteonecrosis of the femoral head are closely related to bone and lipid metabolism.
OBJECTIVE: To explore the relationship between m6A methylation modification and steroid-induced osteonecrosis of the femoral head, as well as the potential mechanism by which Chinese herbal medicine regulates m6A methylation modification to treat steroid-induced osteonecrosis of the femoral head.
METHODS: Using "m6A methylation, steroid-induced avascular necrosis of femoral head/SANFH, bone metabolism, lipid metabolism, Chinese herbal medicine, glucocorticoid" as Chinese and English search terms, a literature search was conducted in Web of Science, PubMed, CNKI, Wanfang, and VIP databases. According to the inclusion and exclusion criteria, 75 articles were included in the final review.
RESULTS AND CONCLUSION: Steroid-induced osteonecrosis of the femoral head has a multifactorial pathogenesis involving imbalances in bone and lipid metabolism. It results from the combined effects of multiple pathological mechanisms. m6A methylation plays a crucial role in bone and lipid metabolism. It influences the proliferation, apoptosis, and differentiation of osteoblasts, osteoclasts, and bone marrow mesenchymal stem cells. It also affects lipid metabolism and angiogenesis. Therefore, m6A methylation may significantly impact the onset and progression of steroid-induced avascular necrosis of the femoral head. Certain traditional Chinese medicines, including monomers, compound formulations, and patented drugs, can modulate osteogenesis by regulating m6A methylation. This process could contribute to preventing and treating steroid-induced avascular necrosis of the femoral head. However, the bidirectional regulatory mechanisms of certain m6A methyltransferases and demethylases, such as methyltransferase-like 3 and demethylase, remain to be fully elucidated. Further research into the interaction between m6A methylation and the development of steroid-induced avascular necrosis of the femoral head is warranted, with the potential to provide novel therapeutic strategies for clinical management.
