本シンポジウムは、国際的に最前線で活躍されている研究者を交えて、「環境」と「生物」のつながりを深く議論することを目的とした。多様な種の確立に至る進化の分子基盤となる、生物の環境応答戦略に関する基礎生物学研究に加え、環境化学物質のヒトや野生生物への影響、実験動物を用いた環境化学物質の作用メカニズムに関する諸問題について議論を進めた。カブトムシ、アリ、アブラムシ、ミジンコ、メダカ、ゼブラフィッシュ、ローチ、アフリカツメガエル、アリゲーターに加えてマウスやヒトなど、様々な動物種をもちいて、環境要因による表現形の可塑性の変化の分子メカニズム、ホルモンや化学物質による変態や性分化異状、生殖の低下などの分子メカニズムについての最新の知見を元に、議論が行われた。15年前に、環境中に放出されているホルモン類似物質による魚類、両生類、爬虫類およびヒトを含めた哺乳動物への影響をどのように解析すべきかを議論するためにNIBB Conferenceを開催した。この15年間の研究の進展は目を見張るものがあり、ホルモン受容体の分子進化や機能の解明、ワニ、ミジンコ、アブラムシを含む各種動物種の性分化機構の解明、各種動物種のゲノムの解明など基礎的な理解が進むとともに、化学物質や環境によるエピジェネテイクスの変化、肥満を誘導するオベソジェンの作用機構、経世代影響、化学物質の複合影響の研究推進の必要性が明らかとなった。基礎生物学的なアプローチを元に、インフォマティクスを用いた大量のデータを用いたアプローチなど幅広い分野から、環境因子に対する生物への影響と その反応について幅広く考える機会となった。
