Outline of Research at the Start

我々のグループは以前、間質性肺炎合併肺癌・機能性RNA発現プロファイルの統合理解から、コラーゲン合成に関与する分子経路の活性化が、癌細胞の発生と転移に重要な役割を担う事を明らかにした。現在、間質性肺炎合併・肺癌患者、エクソソーム由来マイクロRNAの解析を継続している。これまでの解析データから、患者組織で高発現し、エクソソームを介して本疾患の悪化を促進するマイクロRNAの存在が明らかとなってきた。本研究では、間質性肺炎合併・肺癌患者(組織およびエクソソーム)で高発現しているマイクロRNAを起点として、間質性肺炎合併肺癌において特徴的な分子経路を明らかにし、治療法の開発に向ける。

Outline of Final Research Achievements

Analysis of the microRNA expression signature of lung cancer combined with interstitial lung disease (lung squamous cell carcinoma: LUSQ) revealed that expression of miR-150-3p was significantly reduced in cancer tissues. The downregulation of miR-150-3p in LUSQ tissues was confirmed by data in The Cancer Genome Atlas (TCGA). The ectopic expression of miR-150-3p attenuated cancer cell aggressive features, e.g., cell cycle arrest, migration and invasive abilities. Our target search strategy successfully identified a total of 49 putative targets that were listed as subjects of miR-150-3p regulation in LUSQ cells. Interestingly, among these targets, 17 genes were categorized as related to the “cell cycle” based on Gene Ontology (GO) classification.

Academic Significance and Societal Importance of the Research Achievements

肺癌は最も致命的な癌の一つであり、2020年には約7万5千人の患者がこの病気で死亡した。特に間質性肺炎を合併した肺癌患者の治療選択は限定的であり、患者の予後は極めて不良である。現在、間質性肺炎合併肺癌患者に対する有効な治療法は存在しない。
本研究では、間質性肺炎合併肺癌(肺扁平上皮癌)において、miR-150-3pが癌抑制型マイクロRNAであることを明らかにした。疾患の原因について、癌抑制型マイクロRNAの一つが明らかになったことは、治療法の開発に向けた基礎研究としての学術的・社会的に重要な意義を持つ。
