Outline of Final Research Achievements |
ApcMin/+ mice develop spontaneously many intestinal adenomas and are also highly susceptible to radiation. The objective of the current projects was, by utilizing these characteristics of ApcMin/+ mice, to develop a mouse model suitable for the study of radiation-induced cancer risk at low doses and low dose rates. We explored dose rate effects and the effect of genetic background on low dose rate radiation-induced carcinogenesis. We clarified that the genetic background plays a role in dose rate effects on radiation-induced carcinogenesis. Furthermore, we developed a mouse model susceptible to radiation-induced carcinogenesis by using knockout mice that have deficient post-replication repair compared with ApcMin/+ mice.
