ABSTRACT
BACKGROUND: Inflammatory bowel disease is a chronic inflammatory disease associated with intestinal immune, and autophagy is a cell approach to promote immune regulation. Abnormal expression of autophagy-related genes is closely related to intestinal inflammation and immune response. However, the mechanism by which epigenetic modification regulates autophagy in inflammatory bowel disease has not been fully clarified. OBJECTIVE: To introduce the role of epigenetic modification in autophagy, and to promote a further understanding of inflammatory bowel disease. METHODS: A computer-based online research of PubMed database was performed with the key words of “inflammatory bowel disease, autophagy, autophagy-related genes, epigenetic modification, DNA methylation, histone modification, chromatin remodeling, miRNA.” The search time was from January 1998 to April 2019. Finally, 61 eligible articles were included in result analysis. RESULTS AND CONCLUSION: Epigenetic modifications such as DNA methylation, histone modification, chromatin remodeling, non-coding RNA can regulate intestinal inflammation, immune and autophagy through susceptibility genes AGL and IRGM, thereby mediating the occurrence and development of inflammatory bowel disease.
