Outline of Final Research Achievements

Mutations in the TET2 gene, which encodes an enzyme converting methylcytosine to hydroxymethylcytosine in the genome, are frequently found in a wide variety of hematologic malignancies. In this research, we demonstrated frequent novel RHOA gene mutations and the relationship between the mutations of TET2 and RHOA in angioimmunoblastic T-cell lymphoma. These findings were published in Nature Genetics in 2014. Furthermore, using model mice in which TET2 is knocked down, we demonstrated development of T-cell lymphoma and epigenetic dysregulation by the defect of TET2 function.
