Outline of Research at the Start

我々は、CSGSA解析により得られる、再現性のある1例毎約2000のピークに画像化・深層学習を応用して良性婦人科腫瘍と卵巣癌を選別するアルゴリズムを報告した。本研究ではCSGSAをエクソソーム中の糖蛋白に応用し、より感度特異度の高い卵巣癌早期診断法の開発を目指す。

Outline of Final Research Achievements

We have developed (patented) an ovarian cancer detection AI that determines cancer and non-cancer from the peak values of approximately 2000 glycopeptides obtained by degrading blood glycoproteins. In this study, we aimed to create the above detection AI with glycopeptides from glycoproteins in exosomes to increase the specificity and sensitivity of the ovarian cancer detection AI, but the glycopeptides from glycoproteins in exosomes purified from 1000 μL of serum proved to be difficult to analyze due to the small amount.

Academic Significance and Societal Importance of the Research Achievements

エクソソームは細胞外小胞であり、蛋白やRNAなど、起源細胞に由来する多くの分子を含み、疾患バイオマーカーの貯蔵庫と報告されている。我々はエクソソーム中の糖蛋白、そこから得た糖ペプチドに注目し我々の開発した卵巣癌検知AIへの応用を試みたが、残念ながらエクソソーム中の糖蛋白からの糖ペプチドは微量であり解析が困難であった。今後、エクソソーム中の糖蛋白を詳細に解析できる方法が開発されることを期待したい。
