中文摘要
心肌Na/Ca~(2+)交换器是从跳动的心肌细胞中挤出Ca~(2+)的主要机制。为了研究Na/Ca~(2+)交换在心力衰竭进展中的作用,我制造了压力超负荷诱导的左心室肥厚和功能障碍。Na/Ca~(2+)交换活性随心功能衰竭而降低,提示胞浆Ca~(2+)排出减少可能导致心力衰竭。
英文摘要
The cardiac Na+/Ca2+ exchanger is the predominant mechanism for the extrusion of Ca2+ from beating cardiomyocytes. To investigate the role of the Na+/Ca2+ exchanger during progression of heart failure, I generated pressure-overload-induced left ventricular hypertrophy and dysfunction. The Na+/Ca2+ exchanger activity decreased as the cardiac function failed, suggesting that a decrease in the extrusion of cytoplasmic Ca2+ may cause heart failure.
