Outline of Research at the Start

法医鑑定における年齢推定は、歯牙や骨の形態学的な特徴により行われるが、個体差や測定者間誤差が存在することから、異なる年齢推定法の確立が望まれている。近年、DNAのメチル化率に着目した新たな年齢推定法の研究が進められているものの、微量試料からの検討は行われていない。
本研究では、熱安定性に優れた人工核酸Locked Nucleic Acid(LNA)を導入したメチル化解析法を開発することで、微量試料からの高感度な年齢推定法を確立し、遺留資料から被疑者を絞り込む指標としての応用を目指す。

Outline of Final Research Achievements

In this study, we developed the forensic age estimation method of the Japanese population by measuring the methylation rate of DNA using a single-base extension reaction. In addition, we succeeded in increasing the sensitivity by introducing Locked Nucleic Acid (LNA) into each primers.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、微量な試料からのDNAメチル化率に基づく年齢推定法として法医実務へ利用可能である。また、次世代シーケンサーやパイロシーケンサーを必要とせず、コストパフォーマンスに優れた方法でありその有用性は高い。
