Outline of Final Research Achievements

We have developed a method, materials, and devices that enable rapid measurement of chemical modification at the 5-position of cytosine contained in DNA (epigenetics). Linker molecules with a nitrogen mustard were developed in order to perform simple and robust immobilization simply by dropping DNA sample. A microfluidic device and a micro-integrated array device were also developed, we succeeded in rapid and comprehensive analysis of cytosine variants (methylation, hydroxy methylation, formylation, carboxylation) contained in small amounts of DNA sample.

Academic Significance and Societal Importance of the Research Achievements

本申請課題により、単一ゲノムレベルでDNA宙に含まれるシトシン塩基の様々な化学修飾の計測が可能になってきた。多数の正常メチル化細胞集団の中に僅かに含まれる異常メチル化細胞の検出や、CTC検出などの早期がん診断、単一細胞レベルでのリプログラミングや分化誘導評価などにも寄与できると考えており、今後の展開を模索したい。
