| Outline of Final Research Achievements |
To decipher the molecular characteristics of adult T cell leukemia-lymphoma (ATL) and HTLV-1 infected cells, we conducted whole gene expression analysis, epigenome analysis, comprehensive splicing pattern analysis, and translatome analysis. We found that (1) epigenetic abnormality and its biological impact on gene expression, (2) abnormal splicing pattern involved in the leukemogenesis, (3) promoted translation efficiency in acute phase, and (4) persistent activation of signaling pathways including NF-κB, Hedgehog, and TAK1-p38. We also identified some promising molecules for clinical targeting and biomarker. The identified aberrant “quality” and “quantity” of the gene expression pattern appears to be involved in the pathogenesis and development of ATL.
