Outline of Final Research Achievements

In this study, we established Side Population Cell-derived thyroid cell line (SPTL), cell line of mouse thyroid Side Population (SP) cells, to analyze the mechanism of differentiation induction of anaplastic thyroid cancer. By analyzing the gene expression profiles of this SPTL and anaplastic thyroid cancer, we found the group of genes whose expression is increased or decreased. We constructed a doxycycline-inducible Nkx2-1 expressing cell line, and confirmed that Nkx2-1 induced phosphorylation of AKT and that the pathway of AKT is essential in thyroid differentiation.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は甲状腺未分化癌を分化誘導することにより癌の浸潤および転移を制御することにある。さらに、甲状腺幹細胞との比較検討をすることにより甲状腺未分化癌は甲状腺幹細胞と似たような遺伝子発現プロファイルをもつことが確認された。甲状腺幹細胞と癌の分化のメカニズムを解析することにより、新たな癌治療の概念を生み出す大きな意義があると考える。
