Research Abstract

本研究計画は、生殖内分泌調節や行動パターンに見られる性差の神経学的基盤となっている脳の性分化に関わる分子メカニズムの解明を目的として実施した。ラットの脳は周産期におけるエストロゲンの作用で雄型化するので、この時期にエストロゲンにより制御される遺伝子の同定、転写・翻訳ならびにその結果生じる脳機能の表現型である伝達物質、受容体、トランスポータ分子、チャネルを、分子生物学・電気生理学・行動学的手法を用いて研究を進めた。MCF-7細胞におけるエストロゲン反応性を指標に作成したfocused cDNA microarrayを使用して、雌が多数の細胞を擁する前腹側室周核と雄が多数の細胞を擁する内側視索前夜の性的二型核のそれぞれで、出生直後からの脳の性分化の起こる時期に賦活・抑制される遺伝子をスクリーニングし、選択的細胞死と細胞移動に関わる遺伝子群がエストロゲンに反応すること、さらにreal time PCR、ウエスタンブロットによるタンパク同定により、実際にこれらの機構により二つの部位の性差が成立することを解明した。ニューロンへのBrdU取り込みはエストロゲン感受性期には起こらないことから、エストロゲン依存性性分化に細胞新生が関与する可能性は考えにくいと結論した。
