Abstract
Antioxidant vitamins are able to deactivate highly bioactive molecules, such as free radicals, that are generated during cellular biochemical processes. Doxorubicin (DXR) is a cancer chemotherapeutic agent that generates free radicals as a byproduct. In the present study, the Drosophila melanogaster somatic wing spot test was used to evaluate the effects of a mixture of vitamins (Vitamins C, E, and beta-carotene) and minerals (copper, selenium, and zinc), commercially known as Vitergan Zinc Plus, on the genotoxicity of DXR in standard and high-bioactivation crosses of flies. 12.5, 25, and 50 mg/ml of the vitamin/mineral mixture by itself was nongenotoxic in the trans-heterozygous descendants of both crosses, while the mixture produced a significant reduction in the genotoxicity produced by 0.125 mg/ml DXR in the trans-heterozygous descendants of both crosses. The protective effect was observed when the larvae received either pre- or cotreatments of the multivitamin/mineral (MV) mixture. The results indicate that, under these experimental conditions, the MV mixture is not genotoxic; however, it protects against the genotoxic effects of the chemotherapeutic free-radical generator DXR.
