Outline of Annual Research Achievements |
がんの増殖・浸潤・転移には、がん細胞自体の特性のみならず、周囲微小環境との相互作用が大切である。近年接触抑制シグナルの鍵経路としてHippo経路が脚光をあびつつある。しかしながら哺乳類Hippo経路各分子には相同分子が極めて多く、Hippo経路の機能の多くは未だ不明で、Hippo経路によるがん微小環境制御に至っては、まだ解析されていない。また肝がんの中でも、混合型肝がんや(combined hepatocellular and cholangiocarcinomas)肝内胆管がんは、肝細胞がんに比し、治療抵抗性で予後が悪いことから、これら癌の発症・進展メカニズムの解明が望まれている。 肝臓特異的にMOB1を完全欠損させるとオバール細胞(肝幹細胞)や未分化胆管細胞の過形成、及び炎症細胞の蓄積と線維化増生をみ、半数以上のマウスが生後3週以内に死亡した。また3週を過ぎて生存するマウスには、全例肝腫瘍を見たが、なかでも混合型肝がんや(combined hepatocellular and cholangiocarcinomas)肝内胆管がんの発症を多くみた。MOB1欠損肝細胞は細胞増殖亢進、細胞飽和密度の増加、肝細胞の脱分化、上皮間葉転換などをみ、増加した炎症細胞や肝細胞からのTGFb2/3産生亢進や未分化胆管細胞からのSPP1の産生亢進をみた。肝臓特異的なMob1の表現型は、YAP1に強く依存し、TAZやTGFBR2にも部分的に依存した。これらのことからYAP1/TAZやTGFb経路を標的とする薬剤が、混合型肝がんや肝内胆管がんに奏功する可能性が高いことを示した。
