| Outline of Final Research Achievements |
We previously identified that multistep acquisition of mutations are the important mechanisms for T-cell lymphomas. Mutations in TET2 gene, encoding an epigenetic modifier are the key for evolution of premalignant cells. The RHOA mutations are the driver for development of T-lineage tumor cells from premalignant cells. In this study, we established a mouse model showing that the tumors are supported by tumor-infiltrating cells evolved from premalignant cells.
