Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently the most prevalent chronic liver disease worldwide. Its pathogenesis involves the interplay of lipid dysregulation, insulin resistance, oxidative stress, inflammation, gut microbiota dysbiosis, and genetic susceptibility variants. Current therapeutic interventions primarily rely on systemic administration, with their hepatic specificity or selectivity remaining to be improved. Small interfering RNA (siRNA) therapy offers a novel strategy by precisely silencing hepatic pathogenic genes to block aberrant protein synthesis. This review outlines the mechanisms of action and the delivery systems of siRNA therapeutics. Focusing on the core pathological drivers of MASLD, it details the clinical progress and mechanistic insights of siRNA therapeutics within three main areas: Genetic risk variants, lipid metabolism regulation, and fibrosis-inflammation pathways. This article provides an updated reference for siRNA drug development in MASLD.
