Protective role of Apigenin on the status of lipid peroxidation and antioxidant defense against hepatocarcinogenesis in Wistar albino rats

Abstract

Apigenin, a dietary plant derived flavone subclass of flavonoid is expected to play a role in cancer chemoprevention and cancer chemotherapy. Here we designed our experiment to establish whether treatment of apigenin (25 mg/kg body weight) for 14 consecutive days to (N-nitrosodiethylamine) DEN induced (200 mg/kg body weight; by single ip. injection) and phenobarbital promoted (0.05% through drinking water for 14 successive weeks) rats provide protection against the oxidative stress caused by the carcinogen. The level of lipid peroxidation (LPO) markedly increased in carcinogen administered animals, which was brought back to near normal by apigenin treatment. In contrast the activities/levels of the antioxidant status both in liver and kidney were decreased in carcinogen administered animals, which was recouped back to near normal upon apigenin administration. From our findings we concluded that apigenin prevents LPO and protects antioxidant system in DEN induced and phenobarbital promoted hepatocellular carcinogenesis.
