Outline of Final Research Achievements |
In this study, we aimed to develop theranostic agents targeting survivin for cancer selective treatment and diagnosis. Therefore, in collaboration with Professor Gambhir of Stanford University, we synthesized and evaluated survivin targeting agents. In addition, we tried to develop nano DDS agents using survivin targeting peptides as carriers. During the research period, we succeeded in developing peptides that bind to survivin protein. We further found that the peptides have antitumor activities via apoptosis. Finally, we tried to develop gold nanoparticles modified with the peptides.

Academic Significance and Societal Importance of the Research Achievements |
Survivinは多くのがん組織に高発現している一方、ほとんどの分化後の正常細胞ではその発現は極めて低レベルである。本研究では、Stanford大学との共同研究にて、がん選択的な治療や診断を目的とした新たなsurvivin標的ペプチド分子の開発に成功し、ナノDDS薬剤への展開の可能性も切り開いた。また、本研究期間内で様々な国際的な研究ネットワークの構築を達成することができたため、今後は、さらなる国際共同研究にて、survivinをはじめとした様々な標的に対するがんの治療や診断に役立つセラノスティク薬剤の創製に繋がることが期待される。
