Mitoquinol mesylate (MITOQ) attenuates diethyl nitrosamine-induced hepatocellular carcinoma through modulation of mitochondrial antioxidant defense systems.

ABSTRACT: Diethyl nitrosamine (DEN) induced cirrhosis-hepatocellular carcinoma (HCC) model associates cancer progression with oxidative stress and mitochondrial dysfunction. This study investigated the effects of mitoquinol mesylate (MitoQ), a mitochondrial-targeted antioxidant on DEN-induced oxidative damage in HCC Wistar rats. Fifty male Wistar rats were randomly divided into five groups. Healthy control, DEN, and MitoQ groups were orally administered exactly 10 mg/kg of distilled water, DEN, and MitoQ, respectively for 16 weeks. Animals in the MitoQ + DEN group were pre-treated with MitoQ for a week followed by co-administration of 10 mg/kg each of MitoQ and DEN. DEN + MitoQ group received DEN for 8 weeks, then co-administration of 10 mg/kg each of DEN and MitoQ till the end of 16th week. Surviva
