Outline of Research at the Start |
卵巣がん特異的に発現する表面タンパク質をプロテオミクスにより網羅的に同定する。その中から正常組織における発現が殆どなく、かつ詳細未解明のタンパク質に着目し、細胞外ドメインや翻訳後修飾を特異的に認識する抗体を開発する。続いて、卵巣がん患者の手術検体を用いて候補分子の診断・予後マーカーとしての有用性を検証する。最後に培養卵巣がん細胞株と卵巣がんオルガノイドにおける貪食能を評価し、抗体薬物複合体を用いた新規治療標的としての可能性を検討する。以上のように、表面タンパク質の網羅的同定を出発点として、その組織診断や治療標的としての有用性を明らかにすることにより、卵巣がんの革新的な診断・治療戦略を推進する。

Outline of Final Research Achievements |
In-depth proteomics analysis revealed 9,000 proteins expressed on the surface of serous ovarian cancer cells. First, using bioinformatics analysis, we discovered Spondin-1 (SPON1) as a protein with a "cell surface signature" that was particularly expressed in ovarian cancer compared to other cancer types. Second, we generated a monoclonal antibody against SPON1 and investigated the correlation between SPON1 expression and clinicopathological factors using immunohistochemistry. Our findings suggested that high SPON1 expression was an independent prognostic factor for ovarian cancer recurrence-free survival. Furthermore, we found SPON1 secretion in both ovarian cancer cell culture media and ovarian cancer patient-derived ascites fluid. With these findings, SPON1 has been identified not only as a prognostic marker but also as a serum diagnostic marker for ovarian cancer.

Academic Significance and Societal Importance of the Research Achievements |
細胞表面タンパク質は、がんの診断・治療標的候補として有望な分子群が濃縮されていると考えられる。しかしながら、実際に卵巣癌細胞の表面に発現するタンパク質を詳細に解析した報告は少ない。本研究で着目したSPON1は、自身が組織診断・予後マーカー、血清診断マーカー、治療標的としての可能性を持つ。従って本研究で確立した細胞表面タンパク質の網羅的同定法は、卵巣癌の新規バイオマーカーの獲得法として有用である。また我々が絞り込んだ他の分子群についても同様に卵巣癌の新規バイオマーカーや治療標的としての有用性が示唆され、卵巣癌の予後延長に寄与できることが期待される。
