Representation of human non-alcoholic fatty liver disease in murine models
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder in industrialized countries. Murine models are the key mechanistic platform for the disease. We systematically evaluated genome-wide mRNA expression data from five commonly used murine models of NAFLD (high-fat diet, MCD diet, streptozotocin diet, PTEN (Fox) KO) in comparison to human data from 39 controls and 77 NAFLD samples spanning the range of the phenotype. First, profound differences between human and murine expression patterns exist, that override any disease or phenotype signature. In fact, from the significantly regulated human genes in NASH/NAFLD only between 1 and 16 are significantly and concordantly regulated in mice. The dataset, depending on mouse model and human phenotype, shows correct reflection of key pathways, lack of regulation, or reverse effects thereby providing a guide for murine model selection in future experiments to improve applicability to human NAFLD.
