心肌松弛缺陷在心力衰竭中起着因果作用。这里展示的是小清蛋白的新体内应用,小清蛋白是一种钙结合蛋白,可促进特殊骨骼肌的超快速松弛。小清蛋白并不在心脏中自然表达。我们表明,小清蛋白基因转移到体内心脏会产生快速骨骼肌特有的小清蛋白水平,导致正常心脏中心脏松弛性能的生理相关加速,并增强心肌松弛减慢的动物模型中的松弛性能。小清蛋白可能具有独特的潜力,可以纠正能量受损的衰竭心脏中的松弛缺陷,因为小清蛋白的松弛增强作用来自于 ATP 独立机制。此外,小白蛋白基因转移可能提供一种新的治疗方法来纠正钙信号通路中导致心脏或其他器官异常生长或损伤的细胞紊乱。
Defective cardiac muscle relaxation plays a causal role in heart failure. Shown here is the new in vivo application of parvalbumin, a calcium-binding protein that facilitates ultrafast relaxation of specialized skeletal muscles. Parvalbumin is not naturally expressed in the heart. We show that parvalbumin gene transfer to the heart in vivo produces levels of parvalbumin characteristic of fast skeletal muscles, causes a physiologically relevant acceleration of heart relaxation performance in normal hearts, and enhances relaxation performance in an animal model of slowed cardiac muscle relaxation. Parvalbumin may offer the unique potential to correct defective relaxation in energetically compromised failing hearts because the relaxation-enhancement effect of parvalbumin arises from an ATP-independent mechanism. Additionally, parvalbumin gene transfer may provide a new therapeutic approach to correct cellular disturbances in calcium signaling pathways that cause abnormal growth or damage in the heart or other organs.
