| Outline of Final Research Achievements |
Naked mole-rat (NMR) is one of only two eusocial mammals like ant or bee. NMR’s maximum lifespan exceeds 30 years although their body size is same as mouse. Moreover, these animals have never been observed any spontaneous tumor formation. The purpose of this study is to test whether NMR cells have the resistance to DNA damage or not. We treated the cells with mitomycin C or radiation, and found that NMR cells may have the resistance to acute DNA damage. Furthermore, we generated knock-in ES cells carrying NMR-gene X, which contribute to the DNA damage response, toward the generation of NMR-gene X knock-in mouse.
