Role of N / 临床肝胆病杂志

ABSTRACT

The phenomenon of N 6 -methyladenosine (m 6 A)-methylation is commonly observed in various tissues and cells of the human body and is the most common type of internal modification in eukaryotic mRNA. m 6 A-methylation is dynamic and reversible, which is regulated by various methyltransferases, demethylases, and m 6 A binding protein. Recent studies have shown that m 6 A modification can affect viral gene expression and plays an important role in the process of HBV infection. This article summarizes the current research status and mechanism of m 6 A-methylation, especially its association with HBV infection. This article also elaborates on the effect of m 6 A modification on HBV transcripts, reviews the research findings of m 6 A in immune response of HBV infection, and summarizes the effect of HBV infection on m 6 A modification in normal host hepatocytes and hepatitis B liver cancer, so as to discuss the development direction and potential value of m 6 A in HBV infection.
