Research Abstract

α-myosin heavy chain (MHC) promoterを用いてSenescence Marker Protein-30(SMP30)遺伝子を心臓にのみ選択的に発現したトランスジェニックマウス(SMP30-TG)を作成した。また、連携研究者の石神博士から提供を受けたSMP30ノックアウトマウス(SMP30-KO)とphenotypeを対比し、SMP30の心筋細胞での機能をin vivoで検討した。SMP30-KOマウスは正常に生まれ、外見上は野生型(WT)マウスと変わりがなかった。しかし、約6ヶ月で半数のマウスが死亡した。死亡したマウスの病理所見は癌や疾患は認められず、臓器全体が萎縮するヒトの老衰に似た症状そのものであった。WTマウスの寿命を考慮すると、SMP30-KOマウスでは約4倍のスピードで老化が進行したことになる。一方、SMP30-TGマウスは成長、繁殖、寿命はいずれもWTマウスと同等であった。
WTマウス、SMP30-TGマウス、SMP30-KOマウスの皮下にインフュージョンポンプを植え込み、アンジオテンシンIIを持続投与した。アンジオテンシンIIを4週間投与した後、心肥大と心機能の変化を心エコー法で測定した。3群間でアンジオテンシンII投与後の心肥大の程度と心機能に有意差を認めなかった。アンジオテンシンII投与後、老化のマーカーであるp21遺伝子の心筋細胞での発現をRT-PCRで検討した。アンジオテンシンIIの投与開始数時間でp21遺伝子の発現増加が認められた。P21遺伝子の発現は、WTマウスに比較し、SMP30-KOマウスで増加傾向、SMP30-TGマウスで低下する傾向を認めた。
