| Outline of Final Research Achievements |
We have idenfied the glioma-homing peptide which shows highly-shifted incorporation to the target, glioblastoma cells, with minimized absorption to the various linegage of normal(non-neoplastic) cells. By additional technical trials, its hydrophobicity and protease-resistance were much improved with practical utility as in vivo imaging and a therapeutic tool. We also succeeded to develope tumor suppressor peptide which restore the lost p14ARF function in glioblastoma cells. Based on these results, we finally developed the homing peptide-p14 tumor suppressor peptide fusion peptide which is expected to serve as a anti-glioblastoma peptide, and its specific action point could be clarified by molecular study to explain its antitumor effect against human glioblastoma cells.

| Academic Significance and Societal Importance of the Research Achievements |
高悪性度脳腫瘍グリオブラストーマは、現行医療においてなお難治悪性腫瘍として危急の解決を求められている疾患の一つであり、特に同腫瘍の急速な脳内進展という性質や進行段階にある同腫瘍に対する医療的制御技術は未だ十分とは言えない状況である。本研究を通じてわれわれは生体内で増殖・進展する高悪性度グリオーマ細胞特異的・選択的に吸収・集積を起こし、抗腫瘍効果を発揮できるポテンシャルを有するペプチド性抗腫瘍剤のプロトタイプの開発に成功した。この知見は発展的に、難治悪性脳腫瘍の新規かつ生体低尾侵襲性治療技術の基盤構築に資するものと考えられる。
