Research Abstract

塩基除去修復(base excision repair:BER)機構の主要酵素であるAP endonuclease(Ape1/ref1)について、本年新たに改良を加えたpcDNA/Ape1、pcDNA/LacZのadenovirusへの組み込み法を確立し、傷害血管局所にApe1を過剰発現させることを可能にした。培養ラット大動脈中膜平滑筋細胞(mSMC)を用い、基準状態および酸化ストレスπ進状態(H_2O_2添加)における酸化的DNA塩基損傷修復活性を、Ape1/ref1の発現状態から検討し、同機構の活性亢進を確認した。また同細胞において温熱刺激(41℃)がHSP72の発現亢進をもたらし、活性酸素の消去作用を発揮することを明らかにした。同時に行なったマウスワイヤー傷害血管モデルの解析では,非障害血管に比し、ワイヤー傷害血管局所においてApe1 geneの著明な発現亢進が確認され,血管傷害・血管リモデリングの過程が、Ape1によって、軽減される可能性が明らかになった。これらの成績は,BER機構の調節による抗酸化修復機序が,新たな生体防御機構として抗動脈硬化作用を発揮しうる可能性を示すものであり、本年度、さらにこの機序の詳細を明らかにすると同時に、HSPとの相互連関を解明する予定である。
