| Outline of Final Research Achievements |
Recent advances in genome sequencing technologies revealed that complicated structural variations, which are assumed to be driven by chromosomal breakage-fusion bridge (BFB) cycle, occur in a variety of cancer genomes, although their carcinogenic implication has not been fully elucidated. In this study, we developed an experimental vector system to introduce BFB mutations in cultured mouse embryonic stem cells. By using this vector system, we also performed a genome-wide screening for regions that can undergo BFB mutations without losing their host cell viability. Interestingly, such regions showed characteristic features of genomic organization.
