abstract：BACKGROUND:Endothelin (ET)-1 and norepinephrine (NE) are involved in myocardial ischemia/reperfusion injury. We investigated the role of ET-1 in ischemia/reperfusion-induced NE overflow and cardiac dysfunction using a selective ET(A) receptor antagonist (ABT-627), a selective ET(B) receptor antagonist (A-192621), and t...

abstract：BACKGROUND:gp130, a signal transducer of the IL-6-related cytokines, is expressed ubiquitously, including in the heart. The activation of gp130 in cardiac myocytes was reported to induce myocardial hypertrophy. The downstream side of gp130 consists of two distinct pathways in cardiac myocytes, one a Janus kinase/signal...
