Outline of Final Research Achievements

Repair process of clustered DNA damage induced by X-irradiation was investigated using EGFP-plasmid DNA transfected into non-irradiated mammalian cells. The repair kinetics of the irradiated plasmids in the cells visualized as the EGFP fluorescence emission indicates that the damage was hardly repaired. Hydrated deoxyribose (dR) films were irradiated with soft X-rays. Yields of desorbed ions from the films were significantly suppressed by water. Molecular dynamics calculation indicates that the fast proton transfer from dR to the hydrated water might cause the suppression. Furthermore, dynamics of low energy secondary electrons around DNA molecule was investigated using a dynamic Monte Carlo code. The results show that pre-hydrated electrons are formed over a few nm from the parent cations and result in additional base lesions, which may be finally converted into a harmful double strand break by base excision processes.
