NOS2 and metabolic dysfunction-associated steatotic liver disease: Analysis of several parameters associated with the pathogenesis of NAFLD revealed that the liver weights were higher in iNOS+/+/HFD mice compared with iNOS−/−/HFD mice at 10 weeks; and that serum adiponectin, leptin and NEFA levels were significantly higher in iNOS−/−/HFD mice compared with iNOS+/+/HFD mice at 48 weeks.
