Outline of Research at the Start

本研究提案では、微量の生体試料中のO-GlcNAc化タンパク質を網羅的に解析する技術の開発を行う。3年計画で、O-GlcNAc付加糖ペプチドの特異的精製法確立を含むO-GlcNAc付加部位の網羅的プロファイル法の開発を行い、癌細胞株を用いて世界最高深度の網羅的O-GlcNAc修飾サイト同定を行う。最終的にO-GlcNAc修飾昂進によって引き起こされる癌特異的転写、細胞内シグナル伝達調節機構の解明を目標とする。

Outline of Final Research Achievements

The objective of this study was to simultaneously identify cancer-specific O-GlcNAc modification sites by utilizing an original technique for comprehensive analysis of O-glycan binding sites by mass spectrometry. By establishing a method to concentrate O-glycopeptides with more than 100-fold higher enrichment efficiency, we succeeded in identifying many previously unreported O-glycosylation sites. We also analyzed colorectal cancer surgical specimens and found sites/proteins with significantly different modification frequencies in cancer tissues compared to adjacent normal areas.

Academic Significance and Societal Importance of the Research Achievements

がんではタンパク質のO-GlcNAc化の昂進が高頻度に見られ、リン酸化と共にがん細胞の増殖、浸潤、転移などに関与するという報告もある。しかし、これまでO-GlcNAc修飾の変化を付加部位ごとに、高感度に、かつ網羅的に調べる技術は存在せず、O-GlcNAc修飾が持つ生理機能はごく限られた断片的な知見しか得られていない。本研究によってがん組織でO型糖鎖付加が昂進する意義やメカニズムの解明につながれば、新規糖鎖標的治療薬・診断薬のターゲット探索へも応用可能と期待される。
