Research Progress on the Relationship between miRNAs and Common Liver Diseases / 浙江中医药大学学报

ABSTRACT

[Obiective] To summarize the research development of the relationship between the occurrence and development of common liver diseases and miRNAs by reading and analysing the literature published in recent 10 years. [Method] By literature retrieval, we consult the literature about miRNA and the clinical research of relevant liver diseases since 2003 and summarize the regulatory mechanism of miRNAs in liver diseases. [Result] miRNAs regulate the expression of target genes at the post-transcriptional level, and they are involved in many important biological processes. In recent years, we can find that miRNAs take part in the regulation of many liver disease-related genes, and the expression level in hepatocellular carcinoma, viral hepatitis, liver fibro-sis, cirrhosis, alcoholic and non-alcoholic fatty liver change in different levels. Part of the regulatory mechanism of miRNAs has been clearly identified, suggesting that miRNAs wil be used as new therapeutic targets for liver diseases. [Conclusion] The regulatory mechanisms of miRNAs in liver diseases make a big difference for the prevention and treatment of liver diseases. These findings provide some novel thoughts about the detection, study and treat-ment about relevant liver diseases. However, many questions are stil vague and unknown, such as the net of its expression and regulation, its biological functions, and the relationship with liver diseases, and al of them are needed to get further attention.
