Disease relevance of EDN1

 

High impact information on EDN1

  • Stimulation of myocardial Na(+)-independent Cl(-)-HCO(3)(-) exchanger by angiotensin II is mediated by endogenous endothelin [6].
  • This effect was canceled by previous exposure to either 50 nmol/L PD 142,893 (nonselective endothelin receptor blocker) or 300 nmol/L BQ 123 (selective blocker of ET(A) receptors) [6].
  • Exposure to ET-1 (10 nmol/L) raised pH(i) by 0.13+/-0.03 U (P<0.05) in papillary muscles superfused with nominally HCO(3)(-)-free solution, whereas no significant change was detected under CO(2)/HCO(3)(-)-buffered medium [6].
  • The rate of pH(i) recovery from trimethylamine hydrochloride-induced intracellular alkaline load was enhanced so that net HCO(3) efflux increased about three times in the presence of ET-1 (2.74+/-0.25 versus 9.66+/-1.29 mmol. L(-1). min(-1) at pH(i) 7.55, P<0.05) [6].
  • The increased PMN adherence to thrombin- or histamine-stimulated endothelium, which was blocked by an anti-P-selectin monoclonal antibody, was also significantly attenuated by preincubation of coronary segments with (100 nmol/L) ET-1 [1].
 

Chemical compound and disease context of EDN1

 

Biological context of EDN1

  • Vasoconstrictions induced by endothelin were extremely prolonged, persisting for approximately 90 min after a single microapplication [11].
  • Low doses of ET-1 (0.01 and 0.1 nmol) elicited mild but significant reductions in CBV without changes in the systemic arterial blood pressure (SABP) [12].
  • The effects of intracarotidly injected endothelin (ET)-1 (0.01-3 nmol) on the local cerebral blood volume (CBV) in the parietotemporal cortex were examined by the photoelectric method in 17 anesthetized cats [12].
  • The perivascular co-application of PD156707 and ET-1 (10 nM) effected a dose-dependent attenuation of the ET-1 vasoconstrictive response (IC50 = 0.1 microM) [13].
  • In this study, we have examined basic mechanisms underlying the contractile response of cerebral vessels to endothelin using in vitro pharmacology and electrophysiology [14].

Analytical, diagnostic and therapeutic context of EDN1

  • Constriction/dilatation of the cerebral microvessels by intravascular endothelin-1 in cats [12].
  • Endothelin receptor antagonist increases cerebral perfusion and reduces ischaemic damage in feline focal cerebral ischaemia [13].
  • RIA of corresponding nonradiolabeled HPLC elution demonstrated a significantly increased release of PGE2, PGF2 alpha, and 12-HETE as well as 5-HETE in response to ET-1 stimulation [22].
  • 5-HETE release from ET-1-stimulated cells was further identified by gas chromatography/mass spectrometry (GC/MS) [22].
  • Real-time RT-PCR measurements of prepro-ET-1, -ET-2, and -ET-3 were performed before and 5, 15, and 30 min after stretch [23].
