Outline of Research at the Start

肝細胞・胆管細胞間の形質転換,肝内胆管癌源・癌細胞の肝細胞系性質の獲得という事象が示されているが,それに必要なNotchやWntシグナルが活性化するためには癌細胞と癌間質細胞のcrosstalkが必要である、という点に着目し,癌間質微小環境を制御することで肝内胆管癌を肝細胞系腫瘍に分化誘導させられないか,を検討する。そのために,臨床検体を用いてそれらの動態を評価するとともに三次元細胞培養やマウスモデルを用いて癌細胞と間質細胞の相互作用を評価する。

Outline of Final Research Achievements

Notch2 and LGR5 were expressed in 56% and 72% of cases with intrahepatic cholangiocarcinoma, respectively. In vivo and in vitro studies suggested that Notch2 is involved in the differentiation of intrahepatic cholangiocarcinoma cells into more mature cholangiocyte-like cells, resulting in reduced aggressiveness, while LGR5 may be involved in the stemness of intrahepatic cholangiocarcinoma cells, and increase their aggressiveness. In addition, Wnt signaling is also involved in the acquisition of EMT and stemness and was suggested to play an important role in the induction and maintenance of cancer-initiating cells. Furthermore, p-FAK was expressed in 60% of intrahepatic cholangiocarcinoma cases, and the survival of patients with positive p-FAK expression was significantly worse than that of patients with negative p-FAK expression. It was also found that p-FAK may be involved in the CAF activation.

Academic Significance and Societal Importance of the Research Achievements

肝内胆管癌は,生物学的多様性に富む腫瘍であり、その予後も症例によって大きく異なる。本研究ではそのような疾患に対し,その異なる悪性度を引き起こすメカニズムを癌細胞の分化動態に注目し、Notch シグナルとWntシグナルがその過程に重要であることを明らかにした。また、癌間質微小環境のCAFの活性化が本疾患の悪性度を高め、そこにはp-FAKの発現が重要である可能性を見出した。これらは本疾患に対する新たな治療法開発の基礎となるものと考えられた。
