The interplay between N6-methyladenosine and precancerous liver disease: molecular functions and mechanisms

Abstract

N6-methyladenosine(m6A) is one of the most abundant modifications of mammalian cellular RNAs. m6A regulates various biological functions in epitranscriptomic ways, including RNA stability, decay, splicing, translation and nuclear export. Recent studies have indicated the growing importance of m6A modification in precancerous disease, influencing viral replication, immune escape, and carcinogenesis. Here, we review the role of m6A modification in HBV/HCV infection, NAFLD and liver fibrosis, and its function in liver disease pathogenesis. Our review will provide a new sight for the innovative treatment strategy for precancerous liver disease.
