| Outline of Final Research Achievements |
Enhancing the antitumor effect of radiation while reducing organ damage is an important challenge of radiotherapy for oral malignancies. One of the promising radiosensitizers is gold nanoparticles. The aim of this study was to investigate whether gold nanoparticles could enhance the effect of X-ray irradiation on oral cancer cells. In conclusion, the combination of AuNP and x-ray irradiation enhanced the cytotoxic effect on human oral cancer cells in vitro via induction of apoptosis, but did not inhibit cell proliferation.

| Academic Significance and Societal Importance of the Research Achievements |
金ナノ粒子併用の放射線療法は、放射線抵抗性を示す難治性の口腔癌患者に対する新たな治療法として期待される。またナノ粒子表面に口腔癌でも分子標的薬として臨床応用されている抗EGFR抗体などの生体分子を修飾することでより強い口腔癌細胞に対するターゲッティング機能を付与することが可能になると共に、これまでにないin vivoナノイメージングへの展開も期待される。
