Metabolic dysfunction-associated steatotic liver disease and steatohepatitis-associated hepatocarcinoma preclinical models

Metabolic dysfunction-associated steatotic liver disease (MASLD) encompasses liver steatosis and metabolic dysfunction-associated steatohepatitis (MASH), which can result in fibrosis and/or cirrhosis and increase the risk of hepatocellular carcinoma (HCC). The latest Clinical Practice Guidelines acknowledge the importance of systemic metabolic dysfunction as a driver of hepatic lipid accumulation and disease progression. To ensure translational relevance of preclinical models, they need to faithfully replicate the key human pathophysiological characteristics of MASLD and its progression to fibrosis and HCC. This Review discusses the strengths and weaknesses of prevalent MASLD and MASH-HCC preclinical models,…
