Outline of Final Research Achievements

In an international collaborative study, plasma miRNA profiles of lung adenocarcinoma and lung non-adenocarcinoma were compared using miRNA microarrays, and plasma miRNA signatures were found to be useful as predictive biomarkers for recurrence and prognosis in early stage lung adenocarcinoma. This finding was reported at the AACR Annual Meeting 2023 (presenting author). The manuscript was accepted for publication in the International Journal of Molecular Sciences.

Academic Significance and Societal Importance of the Research Achievements

肺癌の新規治療薬が年々開発されている中で、小細胞癌、大細胞癌や扁平上皮癌など非腺癌の5年生存率は45-60%と、腺癌と比較して未だに予後不良である。本研究では、肺非腺癌の腫瘍組織から、患者腫瘍組織移植(Patient-derived xenograft; PDX)モデルを作成し、エクソーム解析とトランスクリプトーム解析に加えて、サーフェスオーム解析とリン酸化プロテオーム解析を行った。
またPDX作成とともに、肺非腺癌由来PDX腫瘍と比較対照となる肺腺癌由来PDX腫瘍のオミクス解析を進めた。
