IAPP and metabolic dysfunction-associated steatohepatitis: Currently, simple and cost-effective modeling methods, such as a high-fat diet (HFD), methionine choline-deficient (MCD), and Gubra–Amylin NASH (GAN) diet, are widely used to mimic NAFLD/NASH in mice; these methods involve lipid metabolism, inflammation, oxidative stress, and fibrotic pathways through a lack of energy or hepatic lipid content and alter the expression of proteins to achieve the pathological symptoms of HF.
