| Outline of Final Research Achievements |
“Epigenetic therapy” and “tumor immunotherapy” have attracted considerable attention in recent years as new therapeutic strategies against tumors. However, how these therapies show anti-tumor effect is not fully understood. In this study, we transplanted murine blood tumors into both immunocompetent C57BL/6 mice and immunodeficient NSG mice, and treated these mice with a variety of drugs. We found that a DNA methylation inhibitor and a p53-activating drug suppressed leukemia progression with the assistance of tumor immunity. Furthermore, we showed the anti-tumor effect of an HDAC inhibitor using a mouse model for myelodysplastic syndrome. These findings will be the basis of future development of new epigenetic therapies and tumor immunotherapies for hematopoietic neoplasms.
