Outline of Final Research Achievements

Cholangiocarcinoma is a refractory cancer with few treatment options. We focused on cancer stem cells to identify novel therapeutic targets in cholangiocarcinoma. We found that the BEX2 gene is required for the maintenance of dormant cancer stem cells. This molecule also increased malignancy not only in cholangiocarcinoma but also in hepatocellular carcinoma and gastric cancer. Small molecule screening identified a hit compound that degraded the BEX2 protein, and this compound reduced dormant cells and increased sensitivity to chemotherapy. Based on these findings, BEX2 may be an effective therapeutic target.

Academic Significance and Societal Importance of the Research Achievements

これまで、幾多の抗癌剤が臨床の現場で使用されてきたが、抗癌剤によって癌を完治させることはほぼ不可能であった。この原因として考えられている癌幹細胞の存在であり、今回私たちは新しい治療標的をみつけ、これまで不可能であった静止期の癌幹細胞を標的とした治療が可能となった。この分子は、胆管がんばかりでなく肝細胞がん、胃がんにおいても同様な効果が得られ、幅広い癌腫に対する臨床応用の可能性に期待できる。
