Outline of Research at the Start

本研究は難治性である浸潤性粘液性肺腺癌における、1)エンハンサー・ゲノム転写ネットワークの包括的解析、及び2) 空間トランスクリプトーム解析による遺伝子発現プロファイリングを確立し、それらの統合解析を基に浸潤性粘液性肺腺癌に特徴的な進展形式に関与する因子の解明と新規分子治療標的を同定し、その成果に基づいた個別化医療開発を推進することを目的とする。
以上の2つの検証を順次達成し、浸潤性粘液性肺腺癌の予後改善に向けた臨床医学の基盤を構築する。

Outline of Final Research Achievements

Comprehensive analysis of the enhancer-genome transcriptional network of about 190 lung cancer cases, including invasive mucinous lung adenocarcinoma, revealed the existence of two clusters for each histological type, in addition to the formation of separate clusters for different histological types such as adenocarcinoma, squamous cell carcinoma, and small cell carcinoma. Invasive mucinous lung adenocarcinoma is included in the cluster of adenocarcinomas that includes many non-TRU adenocarcinomas, but further analysis and investigation will be conducted to further understand invasive mucinous lung adenocarcinoma. Derived from this study, we report results from an integrated analysis of CT imaging findings, genetic abnormalities, and mucin expression that support a stepwise progression from a nodular to a pneumonia-like morphology in invasive mucinous lung adenocarcinoma.

Academic Significance and Societal Importance of the Research Achievements

今までの網羅的遺伝子変異検索や免疫組織化学を用いたタンパク発現による理解に加え、今回のゲノム転写ネットワークの包括的理解を含むアプローチにより、浸潤性粘液性肺腺癌を含む肺癌の、より厚くかつ多面的な理解につながった。浸潤性粘液性肺腺癌はnon-TRU腺癌を多く含む腺癌のクラスターに含まれたが、さらなる解析を追加し、新規治療標的・バイオマーカーの同定に向けて検討をすすめる。
