| Outline of Final Research Achievements |
Hyperbaric oxygen treatment combined with radiation therapy improve radiation sensitivity on glioblastoma in our clinical data. In this study, we developed a xenograft animal model and investigated the influence of gene expression in the tumor contrarily in the radiation alone group and the hyperbaric oxygen therapy group on radiation sensitivity. Tet-on expression-inducing strain of tumor cell line U87-MG cells was constructed and induction of gene X expression after spheroid formation was also positive for pimonidazole, a hypoxic marker. It was suggested that gene X contributes to enhancement of radiosensitivity rather than involvement in hypoxia.
