Outline of Research at the Start

本研究計画は、化学物質リスク評価分野において重要視される発生毒性の新たな動物実験代替モデルであるゼブラフィッシュ胚を用いて、社会的・学術的に関心の高い環境汚染物質の毒性評価と作用機序解明を試みる。このため、①胚発生期の曝露で発生毒性を引き起こす化学物質は何か?またその標的器官はどこか?②発生毒性に至るAOPは何か?③AOPにおけるKey Eventは何か?④in vivo・in silico の統合アプローチにより未試験化合物のin vivo 発生毒性をin silico 解析で予測できるか?を明らかにする。

Outline of Final Research Achievements

The present study clarified developmental toxicity caused by a variety of chemical substances and a part of its molecular mechanism using zebrafish embryos. This study also succeeded in establishment of novel in vivo assay systems to evaluate developmental neurotoxicity by a combination of behavioral and neural marker analyses and to assess antiandrogenic potentials by measurement of the androgen receptor responsive gene. Using these assay systems, the present study showed neurodevelopmental toxicity of neonicotinoid pesticides and dose-dependent antiandrogenic response by some pesticides. Additionally, we revealed that in silico docking simulations on ligand binding with zebrafish estrogen receptor subtypes can predict in vivo estrogenic potentials of untested chemicals.

Academic Significance and Societal Importance of the Research Achievements

ゼブラフィッシュ胚を用いた化学物質の発生毒性の評価事例は多いものの、作用機序の解明に至っているケースは少なく、本研究で得られた成果は、AOPの基盤構築のための基礎的知見となり得る。また、本研究を通じて開発された発達期神経毒性や抗アンドロゲン様作用の評価系に加え、これまでに著者らが開発してきた循環障害やエストロゲン様作用の効率的な評価系を用いることで、動物倫理問題を回避でき、化学産業界で今後新たに開発される化学物質やすでに市場に流通している化学物質、さらには環境試料の毒性評価をハイスループットに実施するためのツールとして活用できることから、その学術的・社会的意義は大きい。
