| Outline of Final Research Achievements |
To confirm the epigenetic abnormalities in malignant lymphoma cells, protein expression of methylated histone and histone metyltransferases were confirmed by using whole cell lysate of tumor biopsy cells. The expression level was differ in each sample, suggesting that some genetic abnormalities in genes encoding epigenetic factors may be lying. To perform genetic analyses including epigenetic factors related genes in the most of lymphoma patients, comprehensive genetic analyses strategies using peripheral blood cell-free DNA were established. PB-cfDNA concentration reflects the disease status in diffuse large B-cell lymphoma patients, and it is suggested that PB-cfDNA can be used for genetic analyses using samples harvested serially during disease progression.
