Colorectal cancer (CRC) is one of the most common cancers world-wide, with highest incidence rates in western countries. In recent years, much effort has been dedicated in search for natural or pharmacological preventive agents, which would block or attenuate CRC process. In search for new pharmacological agent, the effects of fullerenol C60 (OH)24 nano particles (FNP) on liver oxidative status and promotion or progression phase of colorectal carcinogenesis in dimethylhydrazine-induced rat model of CRC were investigated. Our results demonstrate that FNP effectively inhibited formation of dysplastic aberrant crypt foci, which are regarded as early histopathological lesions in the pathogenesis of CRC. FNP treatment also improved activity of antioxidant enzymes in the liver.

The purpose was to examine the anti-tumor and antimetastatic activities of fullerenol andtheirrelatedmechanisms.ThirtyEMT-6tumor-bearingmicewereinjectedintraperitoneallywith 0.1 ml saline or 0.1 ml saline containing fullerenol C 60 (OH) 20 (0.08 and 0.4 mg/ml) dailyfor 16 days. Using tumor tissues, we investigated imbalances in the oxidative defense sys-tem and the expression of several angiogenesis factors. C 60 (OH) 20 exhibits anti-tumor andantimetastatic activities in EMT-6 breast cancer metastasis model. Treatment withC 60 (OH)20 was found to modulate oxidative stress significantly. The expression of severalangiogenesis factors was reduced in tumor tissues after treatment with fullerenol.

Aim: To estimate the impact of C(60) fullerene aqueous solution (C(60)FAS) on the rate of transplanted malignant tumor growth and metastasis.

Conclusion: It was found that water-soluble pristine С(60) fullerenes efficiently inhibit the transplanted malignant tumor growth and metastasis.
