Outline of Final Research Achievements |
None has linked the retrotransposition of human endogenous retrovirus elements (HERVs) and genomic instability in tumors due to the technical difficulty to analyze repetitive sequences. In this study, we have developed the technology using the inverse PCR and high throughput sequencing methods, in which the flanking regions of HERVs were amplified and sequenced. In the analysis targeting HML-2, a group of HERV, approximately 50% of HML-2_LTR sites were reproducibly detected. Furthermore, multiple candidates of novel HML-2_LTR sites were also identified in tumor genomes. This result will help to reveal presence and functions of HML-2 retrotranspositions tumor genomes.
