There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.
人及哺乳动物体内有四种结构及药理学性质略有差异的异物体,分别为ET-1、ET-2、ET-3、ET-β,而在人主要是ET-1,在生理条件下,ET-1在血浆中含量较低,约为5ng〓,故ET-1不是一个循环激素,而是局部合成释放,局部起作用的活性物质,半衰期约1小时,ET-1是目前已知的最强的血管收缩剂,对静脉的作用比动脉强,在血管床,ET受体有A、B两型,A型主要分布在平滑肌细胞,B型主要分布在内皮细胞,它可以通过旁分泌途径刺激内膜增生,具有有丝分裂原效应,可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩,使静止期SMC进入增殖期,还可以通过信号传导途径,与bFGF、GTF-β、PDGF等生长因子协同作用,起共有丝分裂原作用。
