Example Sentences:
(1) [125I]ET-1 binding to ETB receptors (nonselective to ET isopeptides) in cerebellar membranes was not inhibited by either of these compounds even at 100 microM.
(2) The precursor forms big ET-1 and big ET-3 were poor ligands although big ET-1 was more active on the ETA site than big ET-3 on the ETB site.
(3) ETB mRNA is more widely distributed in various cell types of many tissues.
(4) Differential stimulation of phosphatidyl inositol turnover in rat tissue slices by ET-1 and S6c indicates that both ETA and ETB subtypes represent functional receptors.
(5) Screening S. aureus-isolates for the production of exfoliative toxin (ET) and discrimination between its two known variants (ETA, ETB) by immunodiffusion (ID), isoelectric focusing (IEF) and animal experiment were assessed methodologically using isolates from a patient with bullous impetigo and a patient with Ritter von Rittershain's disease.
(6) The ETB-selective peptides, ET-3, sarafotoxin (SFX) S6a, SFX S6b and SFX S6c and the ETA-selective antagonist, BQ-123, generated shallow inhibition curves of [125I]ET-1 binding indicating the presence of both ETA and ETB receptors in the lung.
(7) The truncated linear peptides 4AlaET-1(6-21), 4AlaET-1(8-21) and N-acetyl-4AlaET-1(10-21) still had high affinity for ETB, whereas 4AlaET-1(6-20) and 4AlaET-1(11-21) displayed remarkably reduced affinity for ETB.
(8) They claim that at a time when everyone is having to decrease budgets, the cited "lack of aesthetic innovation" at the ETB was clutching at straws to find a reason to cut its already modest budget from €110,000 (£78,000) to €100,000 next year, and thereafter to remove it altogether.
(9) Northern blot analysis revealed that ETB receptor mRNA level in DBcAMP-treated AC was markedly higher than that in AC untreated with DBcAMP.
(10) The findings were compared with the situation in naturally infected humans and in hamsters infected inapparently (experimentally) with ETBE virus.
(11) Marked regional differences were however observed which might be partly related to different levels of functional antagonism between ETB- and ETA-mediated effects, but differences in receptor types, or subtypes, cannot be excluded, mainly in the mesenteric and renals beds.
(12) ), suggesting that the ETB receptor subtype may be important in cardiovascular function.
(13) These data indicate that BQ-3020 has ETB agonistic activity.
(14) Endothelin-receptors seem to be of different types in placenta (ETB type) and umbilical vessels (ETA type).
(15) Following blockade by BQ-153 the vasodilator response was unaffected and a residual pressor response remained, suggesting that either or both of these effects were mediated either through an ETB or a novel, as yet undefined, endothelin receptor.
(16) In the presence of 1 microM BQ123, [125I]ET-1 binding was decreased by 25-30%, whereas [125I]ET-3 binding was unaffected, confirming that 30-35% of ET receptors belong to the ETA subtypes, and that [125I]ET-1 bound to both ETA and ETB receptors with the same high affinity, but [125I]ET-3 bound only to ETB receptors with high affinity.
(17) Of the synthetic analogs based on ETA antagonist BE-18257A isolated from Streptomyces misakiensis (IC50 value for ETA receptor on porcine aortic smooth muscle cells (VSMCs); 1.4 microM), the compounds BQ-123 and BQ-153 greatly improved the binding affinity of [125I]ET-1 for ETA receptors on VSMCs (IC50; 7.3 and 8.6 nM, respectively), whereas they barely inhibited [125I]ET-1 binding to ETB receptors (nonselective with respect to isopeptides of ET family) in the cerebellar membranes (IC50; 18 and 54 microM, respectively).

(19) The pharmacological profile of these sites is indicative of the endothelin receptor type B (ETB-R).
(20) There is no significant expression of ETB mRNA in vascular smooth muscle cells, and ETA, thus, plays a primary role in ET-induced vascular contraction.
