Background The options for the treatment of nonalcoholic steatohepatitis (NASH) are limited. We examined the effects of ipragliflozin, a sodium-glucose cotransporter 2 inhibitor, on the fatty liver Shionogi (FLS)-ob/ob mice, a non-alcoholic steatohepatitis mouse model.
Methods FLS-ob/ob male mice were treated with vehicle (n = 10) and ipragliflozin (n = 8). Serum metabolic markers, histopathology of the liver, hepatic cholesterol and triglyceride levels and hepatic mRNA levels related to fibrosis, lipid metabolism and endoplasmic reticulum (ER) stress were compared between the two groups.
Results The body weight and hepatic cholesterol and triglyceride levels were significantly decreased in the ipragliflozin group compared with the control group. Hepatic steatosis and fibrosis were significantly ameliorated by the treatment with ipragliflozin. Hepatic infiltration of macrophage, expression levels of 8-hydroxy-2-deoxyguanosine (8-OHdG) and hepatic mRNA levels of ER stress markers were not significantly modulated by the treatment with ipragliflozin.
Conclusion Ipragliflozin can be a therapeutic option for patients with NASH. The precise mechanisms of action need to be clarified in future studies.
