| Outline of Final Research Achievements |
We aimed to develop chlorambucil-PI polyamide (ChB-PIP), which alkylates a fusion gene specific for intrahepatic cholangiocarcinoma (ICC) and kills only cells contain the fusion gene. ChB-PIP was prepared by purification and analysis by high performance liquid chromatography (HPLC), and the synthesis of ChB-PIP that specifically binds to the fusion gene was confirmed by gel shift assay. Then, a transient expression strain was prepared for the ICC cell line. Next, in order to establish a stable strain, after transfection, selection was performed using G418 (Geneticin) to scale up the cells.In the fusion gene plasmid-introduced group, the gene expression level was higher than that in the control group, and it was confirmed that a stable strain was produced.

| Academic Significance and Societal Importance of the Research Achievements |
配列特異的にDNAに結合する性質を持つピロール・イミダゾール・ポリアミド(PIP)を用いて、融合領域を認識するPIPにアルキル化剤クロラムブシル(ChB)を付加したFGFR2-BICC1融合遺伝子認識ChB-PIPの合成を成功させた。また、融合遺伝子2種のいずれかの存在が確認されているICC細胞株が樹立されていないことから、安定株の作製を成功させた。
