N6-腺苷酸甲基化（m6A）是真核细胞中最丰富、分布最广泛的RNA内部修饰，参与多种细胞基因表达调控与生物学过程。近年来，m6A修饰在口腔领域中的作用研究逐渐增多。研究显示，多种m6A相关蛋白参与调控口腔鳞状细胞癌的发生发展及其对药物的耐受性；甲基化转移酶样蛋白3参与调控软骨细胞的凋亡和自噬、内皮祖细胞的血管生成和成骨能力、牙髓细胞的炎症反应、牙髓干细胞的分化和成骨过程、牙根的发育过程以及骨髓间充质干细胞的方向等；m6A修饰亦可能与牙周炎、口腔溃疡及口腔黏膜下纤维化的发病有关。这些研究为多种口腔疾病的发病机制和口腔骨组织修复及再生的研究提供了新思路。本文总结近年 m6A 修饰在口腔领域中的作用相关研究现状及进展，旨在为进一步研究m6A在口腔领域中的作用和机制提供参考。 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.
