Biochanin A prevents buccal pouch carcinogenesis by enhancing carcinogen detoxification and antioxidant status in hamsters

Abstract

Objective: This study objective was to ascertain the drug biochanin A (BCA) impacts on the management of oral squamous cell carcinoma (OSCC) caused by the chemical 7,12-dimethylbenz[a]anthracene (DMBA) in male Syrian golden hamsters. Methods: The oral cancer was induced by the application of a DMBA (0.5 %) thrice a week for the duration of fourteen weeks in the buccal pouch. The study assessed various parameters, including volume, incidence, and burden of tumors within the hamsters' buccal pouches. Additionally, it employed colorimetric methods to measure the levels of carcinogen-detoxifying agents, lipid peroxidation, and antioxidant activity. The histopathological examination was assessed in the buccal tissues, as well. Results: The hamsters exposed to DMBA exhibited the growth of tumors throughout the buccal pouches, accompanied by notable changes in lipid peroxidation, antioxidant levels, and carcinogen-detoxifying agents. However, oral administration of BCA (20 mg/kg bw) every second day for fourteen weeks showed significant alteration in the histopathological changes and reduced incidence, volume, and burden of tumors in DMBA-exposed hamsters. BCA established substantial anti-lipid peroxidation effects and the ability to enhance antioxidant and carcinogen-detoxifying agent levels in DMBA-exposed animals. Conclusion: The outcomes of this investigation emphasize the chemopreventive and antioxidant capability of BCA against DMBA-induced oral carcinoma in hamsters.
