Cisplatin used in treatment of solid tumor induces oxidative stress which leads to hepatotoxicity and nephrotoxicity. New strategies are therefore needed to combat toxicity and optimize its therapeutic potential. Riboflavin (Vitamin B2) under photoillumination works as an anti proliferative agent and induces apoptosis. These properties of riboflavin have been exploited to mitigate cisplatin induced toxicities. 9,10-dimethylbenz(a)anthracene /12-O-tetradecanoylphorbol-13-acetate were used to induce skin tumor in Swiss albino mice. The tumor induced mice were treated with cisplatin, riboflavin as well as their combination under photo illumination. In comparison to tumor control group the cisplatin and riboflavin treated groups showed a compromised level of antioxidant enzymes, functional markers and a higher degree of lipid peroxidation. However these parameters tended towards normal in the combination treated group. The results from histopathology indicate that apoptosis was favored mode of cell death and that necrosis was reduced in combination treated groups. Our findings indicate that combination of cisplatin with riboflavin under photo illumination synergizes its anti cancer activity towards cancer cells and attenuates the cisplatin induced toxicities.
