Advances in Research on Regulatory Mechanism of Abnormal MiRNA Expression in Digestive System Diseases / 胃肠病学

MicroRNA (miRNA) is a non-coding single strand endogenous RNA, with a length of 20-25 bp. It regulates the transcription and translation of target mRNA by binding to its 3' untranslated regions (UTR). Abnormal expression of miRNA plays an important role in the occurrence and development of digestive system diseases. Clarifying the regulatory mechanism of miRNA will be of great help for early diagnosis and treatment of diseases. This article reviewed the advances in research on regulatory mechanism of abnormal miRNA expression in digestive system diseases.
