Outline of Final Research Achievements

ErbB family receptor tyrosine kinase play a critical role for cell growth. In some type of cancer cells, ErbB mutations and amplification induce cancer cell growth. To clarify ErbB regulatory mechanisms are important for overcoming cancer. In this study, new ErbB family feedback regulation was revealed, in which, juxtamembrane domain located conserved Thr was phosphorylated via ERK pathway and then autophosphorylated ErbB tyrosine was reduced. And the involvement of tyrosine phosphatases in this regulation was revealed. Furthermore, oncogenic ErbB mutants showed resistance to feedback regulation.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、チロシンキナーゼ型受容体ErbBファミリーにおいて保存された膜近傍領域のスレオニンリン酸化を介した新規なフィードバック制御による活性調節機構を示した。さらに、がん細胞変異型のErbBではこのフイードバック制御に抵抗性を示すことを明らかにした。患者におけるがん分子標的薬感受性の違いや分子標的薬獲得耐性はがん分子標的治療の障害となっている。がん細胞の増殖を担うErbBファミリーの活性調節機構の解明は、効率的ながん分子標的治療や分子標的薬に対する耐性克服への発展が期待される。
