The intinial amount and repair of DNA double strand breaks (DSBs)in the radiosensitive cell SX-9 and wild-type cell SR-1 irradiated by X ray were detected by pulsed field gel electrophoresis. The results showed that the extent of DNA DSBs was similar in these two cell lines under same X ray doses, but the rejoining repairca pability of DNA DSBs in SX-9 cells was significantly lower than that in SR-1 cells. Results suggested that the increased radiosensitivity in SX-9 cells could be correlated with a defect in the repair of DNA DSBs.
