Outline of Final Research Achievements |
Oral squamous cell carcinoma is the most common type in head and neck cancer. We investigated the functions of Smad-4, Netrin-4, and Sirtuin-7 using a large database and in vivo and in vitro experiments using oral squamous cell carcinoma cell lines. The overexpression of Netrin-4 increased the cell proliferation and migration. The cells overexpressed Netrin-4 in vivo formed larger tumors than controls. These results indicate that Netrin-4 may be involved in the malignant potential of oral squamous cell carcinoma.

Academic Significance and Societal Importance of the Research Achievements |
本研究では分泌タンパク質のNetrin-4が口腔扁平上皮がんの悪性度に関連する可能性を示した.今後Netrin-4の発現や機能解析がさらに進めば,手術療法が中心の口腔がんにおいて,Netrin-4を,血液検査におけるバイオマーカーとすることで,再発や転移のリスクを治療前に判定し,的確な切除範囲の設定と予防郭清を可能にするかもしれない.また,創薬の観点からも有利であり,今後Netrin-4の中和抗体や阻害薬は,実現可能な治療法のターゲットとなり得る.
