Research Abstract

慢性心不全の進行を抑制し、左室収縮機能改善効果を有する薬剤としてβ遮断薬の有用性が明らかにされているが、β遮断薬に対する心機能改善群(responder)と非改善群(non-responder)の存在が問題である。我々はこれまでにthrombospondin-1(TSP-1)がβ遮断薬に対する反応性に関与する可能性を見出した。本研究では、β遮断薬に対する反応性におけるTSP-1の役割を明らかにすることを目的とした。(1)正常健常者でのTSP-1の検討:若年正常健常者例(n=27)においてTSP-1血中濃度を検討した結果、1.14±0.76μg/mlの結果をえた。(2)拡張型心筋症による慢性心不全例群(n=7)と同群にage-matchさせた非慢性心不全例群(n=7)でのTSP-1の検討:age-matchさせた非慢性心不全例群においてTSP-1血中濃度を検討した結果、1.41±0.76μg/mlであった。β遮断薬導入前とβ遮断薬導入後6ヵ月後に拡張型心筋症による慢性心不全例群においてTSP-1血中濃度を検討しβ遮断薬導入前は2.29±0.54μg/ml、β遮断薬導入後6ヵ月後は1.44±1.01μg/mlであった。(3)TSP1遺伝子変異に関する分子生物学的検討:TSP1A1746G(Thr523Ala)遺伝子変異によるmRNA転写量、mRNA安定性、mRNAの二次構造への影響を検討した。その結果、TSP1A1746G(Thr523Ala)遺伝子変異により、mRNA転写量、mRNA安定性に変化は生じないが、mRNA二次構造に変化が生じた。分子生物学的検討の結果からは、TSP-1A1746G(Thr523Ala)遺伝子変異はTSP1血中濃度に影響を与えることが予測され、β遮断薬に対する反応性への関与が推測されるが、さらに今後例数を重ね、検討を進める。
