Core Tip
Core Tip: Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine. N6-methyladenosine (m6A) RNA methylation, which is the most abundant messenger RNA modification in mammalian cells, plays an important role in IBD by influencing various processes, such as RNA stability, splicing, translation, and degradation, and participating in the pathogenesis of IBD. The key enzymes involved in m6A methylation (such as methyltransferase-like 3, methyltransferase-like 4 and fat mass and obesity-associated protein) not only regulate changes in inflammation and immunity in IBD but also bidirectionally regulate the intestinal microenvironment. However, the specific mechanism of m6A methylation modification in IBD needs further exploration. Future research should focus on clarifying the molecular network related to m6A methylation and IBD to provide new intervention methods for clinical practice and improve the outcomes of IBD patients. This article reviews the research progress on m6A RNA methylation in IBD, aiming to improve the understanding of IBD pathogenesis at the epigenetic level and provide new directions for exploring treatments targeting m6A-modified related proteins for IBD.
