  • Metabolic associated fatty liver disease (MAFLD) is a chronic liver disease with a rapidly increasing incidence rate worldwide, and its complex pathogenesis is closely associated with O-linked β-N-acetylglucosamine (O-GlcNAc) modification. As a dynamic and reversible post-translational modification of proteins, O-GlcNAc modification is mainly regulated by O-GlcNAc transferase and O-GlcNAcase. O-GlcNAc modification can drive hepatic steatosis, exacerbate insulin resistance, and impair mitochondrial function, thereby leading to the aggravation of metabolic disorders, promoting inflammation response, and driving the progression of MAFLD to metabolic associated steatohepatitis and hepatic fibrosis. This article systematically reviews the latest research advances in the role of O-GlcNAc modification in the development and progression of MAFLD, in order to provide theoretical support and research direction for a deeper understanding of the pathological mechanism of MAFLD and the development of effective therapeutic strategies.
