Outline of Research at the Start

生体組織における病態分子機構の解明やバイオマーカー開発において、標的定量プロテオミクスが有用な技術であるという認識が定着しつつある。しかし、十分な例数の凍結組織を用いた研究は未だ難しい。また少数の標的タンパク質に限定した解析であることから、得られる情報量に限界であった。これを解決するためには、パラフィン組織を用いたタンパク質発現の網羅的定量法が必要であるが、従来法は再現性が極めて悪かった。本研究では、パラフィン組織を用いた高精度な「プロテオタイピング」によって、分子病理学の新領域を拓くことを目標とする。

Outline of Final Research Achievements

The aim of this study was to realize a new pathological diagnosis called 'proteotyping' with high accuracy using paraffin tissue. We successfully developed a new method to quantitatively elucidate the pathological molecular mechanisms in the tissue regions or cells of interest in paraffin sections, by combining the laser microdissection, facilitated protein extraction and trypsin digestion by the PCT method, accurate and comprehensive mass spectrometry measurements by the SWATH method, and in silico peptide selection in data analysis. The application of this method to tissue sections of cerebral amyloid angiopathy has demonstrated that it is an effective method for exploring and elucidating novel molecular mechanisms in human brain diseases at the protein level.

Academic Significance and Societal Importance of the Research Achievements

タンパク質の“定量”は診断などの様々な臨床的な目的に欠かせない手法である。しかし、日常的な病理診断に利用されているFFPE組織に対して有用な定量法は確立されておらず、挑戦的な課題とされてきた。本研究によって、FFPE検体で利用可能な、高精度かつ網羅的なタンパク質定量技術が開発された。細胞内分子ネットワークでのあらゆる分子・カスケードの活性化状態を定量的に評価する診断基盤が確立し、最も活性化している責任分子・カスケードの同定が可能になり、患者毎に最適化された治療が実現できる。
