Outline of Research at the Start

化学物質等の化合物のヒト健康影響を実施する際に必要となる動物試験数を削減するために、数理科学的手法、統計科学的手法に基づいた化合物の毒性予測手法の構築を目指す。そのために、(1)毒性既知化合物を適切に毒性学的類似性からグループ化する手法、(2)毒性未知化合物と毒性既知化合物との類似性を毒性情報を用いずに評価する手法の2つの研究を進める。また、国際規格を審議するISO等での研究成果の普及活動も行う。

Outline of Final Research Achievements

This research project studied statistical methods related to alternative methods of animal testing. Specially, (1) using the decision tree analysis, we identified key features that discriminate the anemia induction of alinine-related substances and the development of drug-induced liver injury. (2) We discussed challenges faced in implementing "read-across," one of the toxicity prediction frameworks, using the k-nearest neighbor method. (3) We proposed statistical methods for evaluating measurement precision of new test methods when the test results obtained in inter-laboratory comparison studies were ordinal categorical data and dose-response relationships.

Academic Significance and Societal Importance of the Research Achievements

化学物質等のヒト健康影響評価(毒性評価)は,ラット等の実験動物を用いた毒性実験により実施されている.しかし,ほ乳類を用いた動物実験は膨大な時間と費用がかかるだけでなく,動物愛護の観点からも今後も現状の評価方法を続けていくことは国際的に困難な状況であり,動物実験代替法の開発が強く求められている.そのような状況下で本研究課題では,統計的方法により毒性予測モデルを構築するとともに,構築する際に直面する問題点について考察を行った.さらに,新たな試験方法の測定精度を評価する統計的方法の研究開発も行った.そのため,本研究課題の成果は今後の動物実験代替法の開発・普及に大いに役立つものであると考えられる.
