Outline of Final Research Achievements

Receptor tyrosine kinases are involved in cancer progression, and are main target molecules for the development of anti-cancer agents. In this study, we tried to elucidate new mechanisms of their activation by focusing on non-canonical activation. We found that EGFR, an oncogene of lung and colorectal cancers, is regulated by two different mechanisms. One is classically known ligand-bound receptor and the other is ligand-unbound receptor monomers. Especially, the unligande EGFR monomers are endocytosed and then recycled back to the plasma membrane. We also characterized the role of EphA2 receptor in cancer cell migration and found that EphA2 is localized to migrating front via Rab11-containing recycling endosome.

Academic Significance and Societal Importance of the Research Achievements

チロシンキナーゼ型受容体を標的とした、がん分子標的治療が大きく進展している。しかし、その活性化機構には、従来知られている古典的なものに加えて、我々は新しい調節機構の存在を明らかにしている。今回、肺がんや大腸がんの治療標的分子であるEGFRにおいて、二つの目の活性化機構が存在することを見出した。したがって、その活性化機構を標的とした新しい治療戦略の構築に道を拓く研究成果を得ることができた。
