一般描述

内皮素-1(ET-1)是由活化的内皮细胞合成和分泌的,是一种具有强大血管收缩活性的肽。它是活化或功能异常的内皮细胞的一种标志物。该肽是属于内皮素家族的三种异肽之一。它还可由心肌细胞释放。

应用

内皮素-1(ET-1)已被用于研究在有ET-1的情况下H2O2的生成和检测以及NO的生成,用于在隐静脉内皮细胞(HSVEC)中研究ET-1对eNOS/诱导型NOS(iNOS)/小窝蛋白的表达、NO生成、异构体特异性PKC易位和PKC活性的影响。

生化/生理作用

ETA和ETB内皮素受体的一种有效激动剂。 诱导缺氧诱导因子1α的生成,从而生成VEGF。
内皮素-1(ET-1)是一种血管收缩剂,在子宫平滑肌瘤患者的血浆和外植体中具有更高的含量。因此,子宫肌瘤与升高的ET-1水平和高血压有关,而缺氧条件会使这种情况恶化。ET-1 RNAi和Endostar能够预防PC-3(前列腺癌)细胞的进展和侵袭性。患有心房间隔缺损(ASD)的患者血浆中该肽的水平会增加,而这可能有助于闭合缺损的诊断。终末期肾病(ESRD)患者的血浆ET-1水平也较高,而这与肺功能检查的逐渐恶化有关。

Similar to infants born with persistent pulmonary hypertension of the newborn (PPHN), there is an increase in circulating endothelin-1 (ET-1) and decreased endothelial nitric oxide synthase (eNOS) gene expression in an ovine model of PPHN. These abnormalities lead to vasoconstriction

End-stage renal disease (ESRD) is a complex illness that involves different organs including the lungs. We studied the pulmonary function tests, arterial blood gases (ABG) and plasma endothelin-1 (ET-1) levels to check whether there is any change in their levels

Endothelin-1 and Endostar are both significant for the progression, proliferation, metastasis and invasion of cancer. In this paper, we studied the effect of ET-1 RNAi and Endostar in PC-3 prostatic cancer cells. The lentiviral vector was used in the establishment

Endothelin-1 (ET-1) plays an important role in the maintenance of vascular tone and pathological states such as ischemia/reperfusion (I/R) injury, coronary vasospasm, and cardiac allograft vasculopathy. We assessed the effects of elevated ET-1 levels as seen after I/R to determine
Zachary Barrett-O'Keefe et al.
The journals of gerontology. Series A, Biological sciences and medical sciences, 70(5), 554-565 (2014-05-14)
The endothelin-1 vasoconstrictor pathway contributes to age-related elevations in resting peripheral vascular tone primarily through activation of the endothelin subtype A (ET(A)) receptor. However, the regulatory influence of ET(A)-mediated vasoconstriction during exercise in the elderly is unknown. Thus, in 17
