心血管系统钙敏感受体的研究进展

1 概述 钙敏感受体(calcium-sensing receptor, CaSR)是G 蛋白偶联受体C家族成员,该家族成员还包括mGluR、GABA_B受体和信息素受体.CaSR在哺乳动物、鸟、两栖动物、爬虫动物和鱼类均有分布~(1]).1993 年,Brown等~(2])从牛甲状旁腺首次克隆出CaSR.

Investigation progress of CaSR in cardiovascular system

Calcium sensing receptors (CaSR) is a member of super-family of G-protein coupling receptors. This review first introduced the concept, construction features, distribution, functions, decision methods, moderators, genetic locus of CaSR and its relationship with some diseases concisely. Then this article described the investigation progress of CaSR in cardiovascular system intensively, including the expression pattern, role and signal pathways of CaSR in rat myocardium in normal, ischemia-reperfusion injury, apoptosis and cardiac hypertrophy; the role and mechanism of CaSR in calcium homostasis regulation of rat myocardium, endoplasmic reticulum (ER) stress and cardiac ischemic preconditioning and postconditioning. The metabolism rule, physiological significance and pathological action of polyamine in cardiac cells; the increase of CaSR expression in cardiac tissue of artherosclerosic rat and its effect on sensitivity to acute myocardial infarction are also discussed. In the end, the research perspective of CaSR in cardiovascular system was anticipated.
