Outline of Final Research Achievements

Sulfiredoxin was transiently increased and decreased in chronic phase after pressure overload, accompanied by an increase in protein carbonylation. SRX knockout mice showed development of LV remodeling and an increase in protein carbonylation and cleaved caspase 3. In cultured cardiomyocytes, SRX knockdown enhanced H2O2-induced mitochondrial dysfunction. On the other hand, cardiac-specific SRX overexpression mice exhibited attenuation of LV remodeling. Furthermore, these changes were accompanied by suppression of oxidative stress and cell death signaling.

Academic Significance and Societal Importance of the Research Achievements

本研究からSRXは心不全の進展過程において相対的に低下をきたし、その低下により心筋細胞の酸化ストレス、ミトコンドリア機能障害、アポトーシスを引き起こして心筋リモデリングの発症・進展に関与することが示された。SRXが新たな心不全治療ターゲットになるうることが示唆された。
