With an aim to investigate the protective effect of Withaferin-A on 7,12-dimethylbenz[a]anthracene (DMBA) induced oral carcinogenesis in Syrian golden hamsters, tumour incidence, tumour volume and tumour burden and status of detoxication agents, lipid peroxidation and antioxidants in DMBA administered (3 times/week for 14 weeks) hamsters were assessed. Hundred percent tumour formation in DMBA alone administered animal was observed. Oral administration of Withaferin-A (20 mg/kg body weight) to DMBA administered animals for 14 weeks completely prevented the tumour incidence, tumour volume and tumour burden. Also, Withaferin-A showed significant anti-lipid peroxidative and antioxidant properties and maintained the status of phase-I and phase-II detoxication agents during DMBA-induced oral carcinogenesis. The results thus indicate that the protective effect of Withaferin-A is probably due to its anti-lipid peroxidative and antioxidant functions as well as modulating effect on carcinogen detoxication during DMBA-induced oral carcinogenesis.
