Outline of Research at the Start

本研究では1) 膀胱癌細胞株やヒト膀胱癌組織を免疫系の発達が未熟な受精生後間もないゼブラフィッシュの卵黄嚢に移植して、膀胱癌で用いる化学療法剤や新規の様々な分子標的薬の薬効評価系を確立すること、2)ヒト膀胱癌組織の遺伝子発現と化学療法剤・新規分子標的薬に対するゼブラフィッシュヒト癌組織異種移植モデル(zebrafish patient-derived xenograft:zPDX)での反応性とを比較検討して、あらたな診断・治療シーズを見いだすこと、を主な課題とする。以上の目標を達成することで短期に薬物効果を判定可能なモデル(zPDX)の膀胱癌個別化医療への臨床応用につなげることを目指している。

Outline of Final Research Achievements

We have developed human bladder cancer zebrafish xenograft model, which can predict cisplatin sensitivity, by implanting three type of bladder cancer cells: 1) Cisplatin-sensitive bladder cancer cell line, UMUC3 and T24, 2) bladder cancer cells derived from newly established human bladder cancer mouse xenograft models (MieUC series), 3) human bladder cancer tissues directed collected by transurethral resection. This patient-derived xenograft model would be applied to muscle invasive bladder cancer patients for selecting appropriate candidates of cisplatin-based neoadjuvant chemotherapy before radical cystectomy. Moreover, it could also be used to select appropriate drugs for treating patients using their own cancer tissues and realize personalized medicine in the future.

Academic Significance and Societal Importance of the Research Achievements

転移のない筋層浸潤性膀胱癌患者はCDDPを含む化学療法(NAC)を膀胱全摘除術前に行うことが標準的治療であるが、効果は40%と限定であり、効果のない患者はこのNACによる治療の遅れが問題である。従って、NACの効果を予測するマーカーや検査方法の開発が望まれるが、臨床応用可能な方法はない。本研究成果をもとにゼブラフィッシュ異種移植モデルを用いた薬効評価系が確立されれば、この薬剤効果予測に基づいた個別化医療への応用が可能と考える。
