SerpinA3N deficiency attenuates steatosis and enhances insulin signaling in male mice.

ABSTRACT: Aberrant hepatic lipid metabolism is the major cause of non-alcoholic fatty liver disease (NAFLD) and is associated with insulin resistance and type 2 diabetes. Serine (or cysteine) peptidase inhibitor, clade A, member 3N (SerpinA3N) is highly expressed in the liver; however, its functional role in regulating NAFLD and associated metabolic disorders are not known. Male wildtype and hepatocyte Serpina3N knockout (HKO) mice were fed a control diet, methionine- and choline-deficient diet or high-fat high-sucrose diet to induce NAFLD and markers of lipid metabolism and glucose homeostasis were assessed. SerpinA3N protein was markedly induced in mice with fatty livers. Hepatic deletion of SerpinA3N attenuated steatosis which correlated with altered lipid metabolism genes, increased fatty acid o
