| Outline of Final Research Achievements |
This study, using multi-omics approaches, in pursuit of determining potential biomarkers for disease development could achieve following findings: ①Clonality analysis based on provirus integration sites using NGS technology suggested possible applications of clonality in the molecular diagnosis of ATL, as well as predicting ATL development among HTLV-1-infected individuals (Blood advances 2017 and Human genomics 2017)②Development of a new methodology for easy-to-do, rapid and cheap enough analysis of clonality using MinIon sequencer③Showing presence of a high degree of intra-tumor heterogeneity(ITH) based on mutations among ATL patients using Whole Exome Sequencing(Neoplasia 2018).④determining TCR clonality by RNA sequencing might be useful for prognostic purposes and for personalizing ATL diagnosis and assessment of treatments(npj Gen. med.2019).
