Keywords口腔癌 / PXDN / シグナル伝達 / Warburg効果
Outline of Research at the Start

がんのWarburg効果についてはわかっていない点が非常に多い。PXDNの機能や発現調節機構、関連シグナルなどを明らかにすることでがんにおけるWarburg効果の真の意義を明らかにすることが出来るかもしれない。本研究の最終目標は、『微小環境を標的とした新たな治療戦略』として口腔癌の臨床現場への還元を模索することである。
血中や唾液中での発現が明らかとなれば、腫瘍マーカーとして検査分野への貢献も出来ると考えられ、特に唾液中のマーカーとして有用であれば、簡便かつ低侵襲な検査が可能となる。

Outline of Final Research Achievements

The tumor microenvironment formed by the interaction between cancer cells and stromal cells is known to be deeply involved in the proliferation, invasion, metastasis, and treatment resistance of cancer cells. We have found that PXDN may contribute to the energy metabolism of oral cancer and the formation of the local microenvironment in oral cancer. However, there are many unknowns about the abnormality of signals and molecules related to PXDN, so we conducted this study. As a result, it was revealed that PXDN contributes to the invasion, metastasis, and formation of the microenvironment of oral cancer by controlling several novel molecules, including MUC20, an m-mucin, SPRR1B, which controls differentiation into squamous epithelium, and EGR-1, a transcription factor.

Academic Significance and Societal Importance of the Research Achievements

口腔癌は難治性の希少がんであり、術後の重大な審美・機能障害も大きな問題である。本研究成果により、PXDN関連シグナルを標的とした新たな口腔癌分子診断・治療システムの開発、社会実装に直結する可能性が期待される。また、これらの分子のうちMUC20とSPRR1Bは分泌タンパクであることも示され、腫瘍マーカーとしての臨床応用も期待される。これらの分子は唾液中にも分泌される可能性があることを見いだしており、唾液を用いた簡便かつ低侵襲な口腔癌診断システムとしての有用性も期待される。今後も臨床現場への還元を目指すべく、さらなる研究が望まれる。
