The database was created in April and will be updated monthly. At the end of the treatment, NO bioavailability was assayed by Electron Paramagnetic Resonance EPR spectroscopy in venous blood and isolated aortae from mice, as described previously [ 17 ]. The present study was designed to evaluate the beneficial effects of BM, a dual TxAS inhibitor and TP receptor antagonist, on the vasodilatory function and blood pressure in ApoE-KO mice at early stage of atherosclerosis. Although our results are in apparent contradiction with data obtained with another dual TP receptor antagonist and TxAS inhibitor on human umbilical vein endothelial cells [ 45 ], we cannot exclude that a modulation of COX2 expression in smooth muscle cells could explain our results as they were obtained from whole vessels homogenates. Data Availability All relevant data are within the paper and its Supporting Information files. Eminence High School A. In previous in vitro and ex vivo studies, BM has been demonstrated as a potent dual compound able to reduce TxA 2 production by TxAS inhibition and to prevent the action of TxA 2 by blocking the TP receptors [ 12 , 13 ].

A reduced NO-dependent vasodilation is in line with early reports of endothelial dysfunction in resistance vessels from hypercholesterolemic patients [ 30 ]. Data Availability All relevant data are within the paper and its Supporting Information files. This dysfunction 753 from a defect in both NO- and EDH F -mediated vasodilation combined to an altered prostanoid balance. Finally, we evaluated whether treatment with BM could prevent the progression of hypertension observed in ApoE-KO mice.
Srr vasodilation of forearm resistance vessels in hypercholesterolemic humans. Short-term effects of BM were mainly mediated by an increased phosphorylation of both eNOS and Akt, whereas BM in vivo treatment also reduced oxidative stress and restored NO bioavailability.

Although a controversy remains concerning the development of hypertension in ApoE-KO mice [ 214647 ], we analyzed the effects of BM on blood pressure in young ApoE-KO mice ang direct arterial pressure measurements by telemetric recordings. Supplemental Materials and Methods.
BM, a potent dual TxAS inhibitor and TP receptor antagonist [ 12 ], has shown to inhibit the development of vascular atherosclerotic lesions in different animal models of atherosclerosis [ 1415 ]. In that case, the drug was excluded from all bathing solutions during the experimental procedure. In conclusion, our study shows that BM prevents and corrects the vasodilatory dysfunction in resistance arteries at early stage of atherosclerotic lesions by promoting eNOS activity and reducing oxidative stress.
Meir KS, Leitersdorf E. Box 537, Eminence, MO In agreement with our previous results, ApoE-KO mice presented a significant and time-dependent increase of systolic blood pressure concomitant to a slight q2 of heart rate.
Vascular reactivity studies Mice were sacrificed and second branch mesenteric arteries were mounted on a pressure myograph as previously described [ 16 ]. Nitric oxide availability assayed by electron paramagnetic resonance spectroscopy in vivo and in situ At the end of the treatment, NO bioavailability was assayed by Electron Paramagnetic Resonance EPR spectroscopy in venous blood and isolated aortae from mice, as described previously [ 17 ].

Previous studies have also shown that independently, TP receptor antagonists and TxAS inhibitors were able to improve endothelial function in different vascular diseases [ 31 — 33 ]. Endothelial beta3-adrenoreceptors mediate nitric oxide-dependent vasorelaxation of coronary microvessels in response to the amb beta-blocker nebivolol.
In previous in vitro and ex vivo studies, BM has been demonstrated as a potent dual compound able to reduce TxA 2 production by TxAS inhibition and to prevent the action of TxA 2 by blocking the TP receptors [ 1213 ].

Atherosclerosis in the apolipoprotein-E-deficient mouse: J Pharmacol Exp Ther. Improved endothelial function by the thromboxane Annb receptor antagonist S in patients with coronary artery disease treated with aspirin.
We found that the two major endothelium-dependent relaxing pathways, namely nitric oxide NO and endothelium-derived hyperpolarizing factor EDH Fare altered in the vasculature of these young ApoE-KO mice. First, our results showed that resistance microarteries from ApoE-KO mice present an impairment of the vasodilatory response independently anv the onset of plaque formation.

Endothelial regulation of vasomotion in apoE-deficient mice: This database lists all violations and inspection comments. Lack of beneficial metabolic effects of quercetin in adult spontaneously hypertensive rats. Such benefit could be attributed to the antagonism of BM on TP receptors, and the inhibition of deleterious effects from COX-independent such as isoprostanes. Statistical analysis was done by comparing the curve obtained in resistance arteries treated with BM with the control curve by means of a non-repeated measure analysis of variance ANOVA followed by Bonferroni post-hoc test.
Summersville Elementary A. Discussion The present study was designed to evaluate the beneficial effects of BM, a dual TxAS inhibitor and TP receptor antagonist, on the vasodilatory function and blood pressure in ApoE-KO mice at early stage of atherosclerosis.
