[Research progress in N⁶-methyladenosine modification in the field of stomatology]

N⁶-methyladenosine (m6A) is the most abundant and widely distributed internal RNA modification in eukaryotic cells, and it is involved in the regulation of gene expression and biological processes in many cells. In recent years, studies on the role of m6A modification in oral cavity have emerged gradually. Existing researches show that m6A-related proteins are involved in the regulation of oral squamous cell carcinoma and its resistance to therapy. Methyltransferase-like 3 regulates apoptosis and autophagy of chondrocytes in inflammation, the angiogenesis and osteogenesis during distraction osteogenesis of endothelial progenitor cells, inflammatory response of dental pulp cells, the differentiation and osteogenesis of dental pulp stem cells, the development of tooth roots and the differentiation of bone marrow mesenchymal stem cells and so on. Moreover, m6A modification may also be related to the occurrence and development of periodontitis, oral ulcers and oral submucosal fibrosis. These studies have provided new ideas for the pathogenesis of various oral diseases and the diagnosis and treatment of oral bone tissue repair and regeneration. This paper reviews the recent research progress on the role of m6A modification in the field of stomatology and summarize the current research status of m6A in the field of stomatology, in order to provide reference for the further research of m6A function and mechanism in the field of stomatology.
