title: Genetically modified animal models recapitulating molecular events altered in human hepatocarcinogenesis.
abstract: New advancements have been made in recent years in the understanding of the molecular mechanisms that govern human liver tumorigenesis. Experimental animal models have been widely used, especially mouse models. In this review we highlight some of the genetically engineered mouse models that have proved to be excellent tools to study the intracellular signalling pathways altered in hepatocarcinogenesis and establish potential correlations with data from humans, with special focus on hepatocellular carcinoma (HCC), the most common type of primary liver cancer. Information obtained from these animal models will help to design future therapeutic approaches to HCC, particularly those that explore drugs that specifically target the altered molecular pathways.
