·MS-NASH is a polygenic mouse model with an intact leptin pathway that develops many of the features associated with metabolic syndrome

·Progression of NASH can be induced by feeding with an obesogenic diet, resulting in steatosis, inflammation, hepatocellular ballooning, and fibrosis.

·Leptin-deficient ob/ob mice have a genetic predisposition to hyperphagy and obesity.

·Ob/ob mice fed obesogenic and MCD diets exhibit several key NASH features including steatosis and hepatocellular ballooning, but rarely develop significant fibrosis

·Leptin-resistant db/db mice exhibit similar metabolic features to ob/ob mice, but have normal to elevated levels of leptin.

·In contrast to ob/ob mice, db/db mice fed high calorie and MCD diets often develop moderate to severe liver fibrosis.

·C57BL/6J mice are frequently used in NASH research due to their intrinsic predilection to metabolic syndrome and an intact leptin pathway.

·Mice fed specialized diets display a number of key NASH phenotypes, however, obesogenic models typically have incomplete penetrance and require a significant amount of time for induction

·Mc4r-/- mice exhibit hyperphagic obesity in the context of an intact leptin pathway, resulting in a number of key features that are consistent with metabolic syndrome

·When fed a High Fat Diet, these mice have been observed to develop steatosis, inflammation, hepatocellular ballooning, and fibrosis.

- Apoe-/- and Ldlr-/- mice contain genetic mutations in key genes involved with lipoprotein metabolism, resulting in hypercholesterolemia, atherosclerosis, and obesity
- Although traditionally used to study cardiovascular disease, these mice fed NASH-inducing diets develop a number of key features including steatosis, hepatocellular ballooning, inflammation, and fibrosis.

·The SREB-1C gene is involved in glucose metabolism, and the synthesis and uptake of cholesterol, fatty acids, and triglycerides.

·Though the liver histology of this model recapitulate many features of human NASH, it exhibits decreased adipose tissue over time.

·MiR-223 is involved in the differential expression of several key inflammation genes in a number of cell types including neutrophils and hepatocytes.

·MiR-223 -/- have been shown to exhibit steatosis, hepatocellular ballooning, inflammation and fibrosis following induction with high fat diet.
