Outline of Final Research Achievements

We investigated drug resistance mechanism for Fiber Growth Factor Receptor (FGFR) inhibitors on cholangiocarcinoma.
In an in-vitro study, we generated a cell line which possessed drug resistance against FGFR inhibitors using a KMCH cell stain harboring the fibroblast growth factor receptor (FGFR) amplifications. Additionally, we are analyzing what mechanisms are associated with drug resistance for FGFR inhibitors using the cell line.
In an in-vivo study, Copy Number Variation (CNV) analysis was performed using patients-derived xenografts (PDX) administered FGFR inhibitors (Ponatinib or BGJ398) and possessed drug resistance against the inhibitors. Compared with control PDXs, the drug-resistance PDX had some specific gene aberrations. Furthermore, a total of 22 gene aberrations were detected by the comparison between the PDX and a real human tissue sample administered Ponatinib. We are further investigating the role of detected genes by exome sequence using the PDX samples.

Academic Significance and Societal Importance of the Research Achievements

FGFR 阻害剤の薬剤抵抗性獲得に寄与する機序をを検討した。すでにFGFR阻害剤を投与されたサンプルおよび投与されていないサンプルとの比較をすることにより、薬剤耐性に関わる遺伝子を探り出すことができた。FGFR阻害剤は近年胆管癌の治療に有望な分子標的薬として注目されており、一部の胆管癌患者の予後を延長するものと期待されている。その薬剤耐性機序を探るうえでのヒントを見つけ出すことにより、本阻害剤が実際の患者に投与され、耐性となった際の次の治療戦略を考える上で、本研究が重要な意義を果たすものと思われる。
