| Outline of Final Research Achievements |
As a model to evaluate transgenerational risk of radiation exposure to human female, we conducted whole genome sequencing of murine spleen DNA derived from three F1 mice born to mature oocytes that were exposed to 4 Gy of gamma-irradiation, three F1 mice born before irradiation, and their parents. We detected about ten de novo mutation candidates of base change per one F1 mouse that were not observed on other F1 mice and their parents. Base change mutations were observed more in the F1 mice born after irradiation compared to the F1 mice born before irradiation.
