Materials and Methods: C57BL/6N mice were fed a Gubra-Amylin NASH (GAN) diet for 20 weeks to induce NASH. The tranilast groups received oral administration of tranilast at doses of 300, 400 and 500 mg/kg/day, five days per week for 20 weeks, in addition to the GAN diet. The effects of tranilast were assessed based on the dosage of food intake, changes in body weight, liver weight, blood biochemical parameters, histopathological examination, and expression of TRPV2 and inflammatory cytokines. Results: Hepatic expression of TRPV2 was observed in the GAN-fed NASH mouse model. The tranilast groups showed significantly suppressed increases in body and liver weights. The development of intrahepatic fat deposition and liver fibrosis, assessed histopathologically, was inhibited. Tranilast administration improved the expression of TRPV2 and inflammatory cytokines in the liver. Additionally, blood tests indicated a reduction in elevated liver enzyme levels. Conclusion: In GAN diet NASH models, TRPV2 was up-regulated in the liver and tranilast inhibited TRPV2 and suppressed fibrosis. Therefore, it might prevent the incidence of hepatocellular carcinoma associated with NASH.
