Outline of Research at the Start

上皮細胞増殖因子受容体 (EGFR) が変異した非小細胞肺がんは、分子標的治療薬EGFRチロシンキナーゼ阻害剤 (EGFR-TKI) が著効するが、数年後に耐性によりがんが再燃する。この原因のひとつに肝細胞増殖因子受容体c-Metの過剰発現がある。c-Met過剰発現耐性肺がんに対するEGFR-TKI と、c-Met阻害作用を有する麻黄との併用効果を調べた結果、がんの増殖は有意に抑制され、麻黄は過剰発現したc-MetやEGFRの発現を低下させた。本研究では麻黄による受容体のダウンレギュレーションの分子メカニズムを解明し、麻黄をEGFR-TKI耐性肺がんの治療へ応用するためのエビデンスを提示する。

Outline of Final Research Achievements

We have found that Ephedra Herb extract (EHE) induces downregulation of overexpressed c-Met and wild type EGFR in non-small-cell lung cancer (NSCLC) cells. Clinically, NSCLC patients who are eligible for EGFR-tyrosine kinase inhibitor (TKI) treatment are those with detected EGFR with activating mutations. Therefore, in this study, the effect of EHE on EGFR with activating mutations was investigated. EHE induced downregulation of overexpressed EGFR with activating mutations. Moreover, we examined the combined effects of EGFR-TKI, osimertinib, and EHE, because the advanced NSCLC patients are widely treated with osimertinib which binds covalently to the kinase domain of EGFR. EHE downregulated the expression of EGFR bound by osimertinib, and the combination suppressed the proliferation of NSCLC cells more effectively than did osimertinib alone. These results suggested that this combination may be effective in treating patients with advanced NSCLC with EGFR mutation.

Academic Significance and Societal Importance of the Research Achievements

学術的意義:がん細胞に過剰発現したc-Met、EGFR、及び、活性型変異EGFRをダウンレギュレーションするような分子の報告はなく、EHEの作用は新規作用であると考えられる。麻黄は細胞表面に発現する分子に作用して、細胞機能の調整を行っている可能性があり、本研究成果は漢方薬の薬効解明の糸口になると考えられる。
社会的意義:活性型変異を有するEGFR発現NSCLCには分子標的治療薬が有効であるが、c-Metを発現すれば薬剤耐性を引き起こす。EHEは活性型変異EGFRとc-Metの両方に作用することから、再発抑制に有効な併用薬となる可能性がある。
