Outline of Final Research Achievements

In this study, we developed a ultra-small nanocarrier, termed uint polyion complex (uPIC), for cancer-targeted oligonucleotide delivery. Fine-tuning of the length and shape of block copolymers allowed for the formation of ~18 nm-sized uPICs in aqueous media. The uPICs efficiently accumulated in murine models of pancreatic cancer and brain tumor, leading to the significantly enhanced antitumor efficacy.

Academic Significance and Societal Importance of the Research Achievements

本研究は、高分子材料の精密設計を通じて、1分子の核酸医薬を選択的に搭載したポリイオンコンプレックス(PIC)の構築に成功しており、高分子集合体の観点で非常に興味深い知見を得ている。さらに、そのPICのサイズが約18 nmと非常に小さいことに着目し、既存のナノ医薬(約100 nm)では送達困難とされる難治がん組織(膵臓がんや脳腫瘍モデル)に対しても効果的に核酸医薬を送達することに成功した。結果として、安全かつ優れた抗腫瘍効果を得ることに成功しており、新規がん治療法の創出に貢献するものと期待される。
