Outline of Final Research Achievements |
In EGFR-mutated lung adenocarcinoma, the proportion of micropapillary subtype (mPAP) is important for prognosis. In interstitial pneumonia (IIP) -associated lung adenocarcinoma, which has a poor prognosis, a unique cellular feature is shown. In the present study, molecules highly expressed in mPAP were searched using a microarray. Furthermore, the expression of mucin-related molecules in IIP-associated lung adenocarcinoma was investigated, and RAS gene abnormalities in background lesions were examined by digital droplet PCR. In mPAP, increased expression of the DYRK2 gene was observed, which was confirmed by immunohistochemistry and FISH analyses. In lung adenocarcinoma complicated with IIP, expression of various mucus molecules was increased and decreased, and RAS gene abnormality was also observed in the background lesion.

Academic Significance and Societal Importance of the Research Achievements |
日本人に多いEGFR変異肺腺がんにおいて、予後に密接に関連する微小乳頭亜型の発生に関連する分子が明らかになったことは学術的意義が高く、今後の研究によってさらにマーカーの開発、分子を標的にした治療に発展する可能性があり、社会的意義も高いと考えられる。今回明らかにしたDYRK2遺伝子の周囲にはさらに重要な遺伝子が複数存在しており、さらに重要な遺伝子異常が見つかる可能性も秘めている。 IIP合併腺がんにおいてもその病理学的特性がさらに解明されたことは意義が高いと考えられる。背景病変においてもRAS遺伝子の異常が明らかになったが、前癌病変からの発がん過程の解明に発展することが期待される。
