In this paper the radioprotection effects of fullerene derivative (C,60,-Lys) on AHH-1 cells and its protective mechanism have been investigated. The 800 mg/L C,60,-lys can improve the survival rate of irradiated AHH-1 cells, which are 64.6% and 41.3% for the irradiation and control groups at 8 Gy dose, respectively. The cell fluorescence images show that the 16.3% apoptosis rate at 1200 mg/L C,60,-lys is lower than that of the 39.2% irradiation free of C,60,-lys. In the situation with additive 800 mg/L C,60,-lys and 4 Gy of irradiation, the dosed time before or after irradiation significantly affects the average survival rates of AHH-1 cells, which are 85.6% and 64.1%, respectively. In the AHH-1 cells treatment with C,60,-lys can obviously reduce the G,2, blockage of AHH-1 cells induced by 4 Gy radiation, DNA damage and amount of 8-OHdG especially.
