摘要
由21个氨基酸残基组成的内皮素1(ET-1)不仅是已知最强的缩血管活性肽,还对血管形成与重构、细胞增殖、细胞外基质合成和感觉神经活化等诸多生理活动具有调控作用。其生理效应多通过升高胞浆Ca2+继而促发连锁反应来实现。增强细胞外Ca2+内流和促进胞内Ca2+释放是ET-1升高胞浆Ca2+浓度的两条基本途径,同时,通过抑制胞内的Ca2+外排与重摄取及对细胞核等非典型Ca2+库内的Ca2+信号的调控同样可以达到升高胞浆Ca2+浓度的目的,本文主要就ET-1升高胞浆Ca2+的调控途径作一综述。
The 21-amino-acid peptide endothelin-1 （ET-1） regulates a diverse array of physiological processes, including vasoconstriction, vascular remodeling, angiogenesis, cell proliferation, extracellular matrix synthesis and nociception. Most of the effects of ET-I are associated with an increase in [ Ca^2＋ ] ; （ intracellular calcium concentration）. The increase in [ Ca^2＋ ]; aroused by ET-1 can be due to calcium influx or calcium stores release or a portion of both. In addition, ET-1 also can increase [ Ca^2＋ ] either by decreasing Ca^2＋ efflux, suppressing Ca^2＋ reuptake into sarcoplasmic/endoplasmic reticulum or regulating the Ca^2＋ signal in the nucleus. This paper mainly reviews the regulation of ET-1 on the increase in intracellular Ca^2＋ signalling.
