Epigenetics in metabolic dysfunction-associated steatohepatitis.

Metabolic dysfunction-associated steatohepatitis (MASH) is a complex disease involving genetics, environment, and lifestyle, with the potential to progress to liver fibrosis, cirrhosis, and even hepatocellular carcinoma (HCC). Although the pathogenesis of MASH is not fully clear, increasing evidence has indicated that epigenetics plays an important role in the genesis and progression of MASH, during which, as drastic changes in metabolites, epigenetics undergo drastic changes. Roles of chromatin structure, chromatin accessibility, DNA methylation, histone modification, and non-coding RNAs were considered as bridges of pathogenic factors and MASH. In this review, the research progress on the epigenetics of MASH was summarized, and indepth research and therapeutic strategies based on epigenetics is expected to bring new hope to MASH patients.
