Outline of Final Research Achievements |
1) The “complex DNA damages” induced by irradiation make a significant impact on cell inactivation or transformation. Although complex DNA damage formation was dependent on radiation quality in the early phase after irradiation, senescence-like growth arrest was suggested to be the major cellular response in the later phase, regardless of radiation quality. 2) A selective Cox-2 inhibitor “celecoxib” sensitized malignant brain tumor cells to gamma-rays by loading ER stress. The major modality of cell death induced was autophagy, suggesting that celecoxib is a promising candidate for radosensitizing refractory malignant brain tumors. 3) Local cancer radiotherapy may have an effect as an immune adjuvant. We found that a tumor-specific immune system was activated when the primary tumor was cured by irradiation. This “abscopal effect” was effective even in the brain. In contrast, primary tumor recurrence after irradiation resulted in suppression of tumor immunity.
