The goal of this study was to determine whether acetylcholine evokes endothelium-dependent contraction in mouse arteries and to define the mechanisms involved in regulating this response. Arterial rings isolated from wild-type (WT) and endothelial nitric oxide (NO) synthase knockout (eNOS(-/-)) mice were suspended for isometric tension recording. In abdominal aorta from WT mice contracted with phenylephrine, acetylcholine caused a relaxation that reversed at the concentration of 0.3-3 microM… Expand

TLDR
It is concluded that in the chicken DA, stimulation of muscarinic receptors by ACh induces an endothelium-dependent relaxation followed by an endothelial-dependent contraction. Expand
Increased Expression of Cyclooxygenase-2 Mediates Enhanced Contraction to Endothelin ETA Receptor Stimulation in Endothelial Nitric Oxide Synthase Knockout Mice
TLDR
It is demonstrated that COX-2 expression is increased in eNOS−/− mice, which overcomes a reduced expression of ETA receptors and enables a selective increase in contraction to ETA receptor stimulation. Expand
Prostacyclin, but not nitric oxide, is the major mediator of acetylcholine-induced vasodilatation in the isolated mouse heart.
TLDR
In the isolated mouse heart, Ach-induced coronary flow response displays an unusual biphasic nature and is mediated in major part by PGI2, but not by NO, so Ach should be used to assess P GI2-dependent endothelial function. Expand
Vasomotor Reaction to Cyclooxygenase-1-Mediated Prostacyclin Synthesis in Carotid Arteries from Two-Kidney-One-Clip Hypertensive Mice
TLDR
It is demonstrated that as in normotensive conditions, COX-1 is a major contributor of PGI2 synthesis in 2K1C hypertensive carotid arteries, which leads to a vasoconstrictor response resulting from opposing dilator and vasoconStrictor activities of IP and TP receptors, respectively. Expand
A vasoconstrictor role for cyclooxygenase-1-mediated prostacyclin synthesis in mouse renal arteries.
TLDR
In mouse renal arteries, high expression of TP receptors together with little functional involvement from the vasodilator P GI2 receptors results in a potent vasoconstrictor effect evoked by PGI2, which implies that endogenous COX-1-mediated PGI 2 synthesis leads to vasoconStrictor activity and this could be an integral part of endothelium-derived mechanisms in regulating local renal vascular function.

Endothelium-Dependent Contractions in Hypertension: When Prostacyclin Becomes Ugly
TLDR
The present article focuses on the mechanisms leading to the production of endothelial COX-derived vasoconstrictors, in particular, in the rat aorta, which has been the standard preparation used by the author and his collaborators for the study of EDCF-mediated responses. Expand
A vasoconstrictor response to COX-1-mediated prostacyclin synthesis in young rat renal arteries that increases in prehypertensive conditions.
TLDR
Results demonstrate that due to scarcity of IP receptors, PGI2, which is derived mainly from COX-1-mediated metabolism, acts as an EDCF in young WKY renal arteries, and it increases in prehypertensive conditions. Expand
Early Aging and Anatomic Heterogeneity Determine Cyclooxygenase-mediated Vasoconstriction to Angiotensin II in Mice
TLDR
It is demonstrated that COX determines AngII-induced vasoconstriction in the mouse aorta and carotid artery during the early physiological aging process, independent of endothelial NO bioactivity. Expand
Acidosis prevents and alkalosis augments endothelium-dependent contractions in mouse arteries
TLDR
It is demonstrated that changes in pH modulate endothelium-dependent contractions in mouse arteries primarily by altering the sensitivity of TP receptors of vascular smooth muscle to endothelia-derived contracting factors. Expand
Endothelium‐dependent contractions in hypertension
TLDR
Since EDCF causes vasoconstriction by activation of the TP‐receptors on the vascular smooth muscle cells, selective antagonists at these receptors prevent endothelium‐dependent contractions, and curtail the endothelial dysfunction in hypertension and diabetes. Expand

Endothelium-derived contracting factor in carotid artery of hypertensive Dahl rats.
TLDR
The results suggest that ACh causes release of EDCF in carotid rings of hypertensive DS rats, which is likely to be PGH(2) and TXA(2). Expand
Role of prostaglandins in acetylcholine-induced contraction of aorta from spontaneously hypertensive and Wistar-Kyoto rats.
TLDR
It is proposed that PGI2 released in response to acetylcholine may serve as the endothelium-derived contracting factor that elicits the TxA2/PGH2 receptor-independent and dependent components of the acetylCholine-induced contraction. Expand
An endothelium-derived hyperpolarizing factor distinct from NO and prostacyclin is a major endothelium-dependent vasodilator in resistance vessels of wild-type and endothelial NO synthase knockout mice.
TLDR
Results demonstrate that in murine resistance vessels the predominant agonist-induced endothelium-dependent vasodilation in vivo and in vitro is not mediated by NO, PGI(2), or a cytochrome P450 metabolite, but by an EDHF-like principle that requires functional gap junctions. Expand
Endothelin-1-induced responses in isolated mouse vessels: the expression and function of receptor types.
TLDR
The results indicate that the role of ET receptors differs considerably among mouse vessels, and suggest that ET-1 might involve a NOS-dependent vasodilation in the abdominal aorta, which remains to be further defined. Expand
ACh dilates pial arterioles in endothelial and neuronal NOS knockout mice by NO-dependent mechanisms.
TLDR
Findings suggest that an nNOS-dependent mechanism may compensate for the chronic loss of eNOS activity after targeted gene disruption, and results coupled with the TTX results suggest that the response ineNOS mutant mice is partially NOS dependent and attenuated by both TTX and L-NNA. Expand
Role of Prostaglandin H2 as an Endothelium-Derived Contracting Factor in Diabetic State
TLDR
The findings suggest that the impairment of acetylcholine-induced relaxation in the diabetic state is not caused by the diminished production of an endothelium-derived relaxing factor or nitric oxide but rather by the increased endothelia-derived contracting factor or prostaglandin H2, which may be responsible for abnormalities of the vasculature in diabetes.

Acetylcholine‐induced relaxation in blood vessels from endothelial nitric oxide synthase knockout mice
TLDR
It is demonstrated that in the blood vessels studied, the endothelium‐dependent relaxations to acetylcholine involve either NO or the combination of NO plus a product of cyclo‐oxygenase but not EDHF; in the eNOS(−/−) mice, NO‐dependent responses and EDHF‐like responses were not observed. Expand
Enhanced release of prostaglandins contributes to flow-induced arteriolar dilation in eNOS knockout mice.
TLDR
It is demonstrated that, despite the lack of nitric oxide mediation, flow-induced dilation is close to normal in arterioles of eNOS-KO mice because of an enhanced release of endothelial dilator prostaglandins and suggested that this vascular adaptation may contribute to the regulation of peripheral resistance in eNos- KO mice. Expand
Hypertension in mice lacking the gene for endothelial nitric oxide synthase
TLDR
Responses to NOS blockade in the mutant mice suggest that non-endothelial isoforms of NOS may be involved in maintaining blood pressure, and eNOS mediates basal vasodilation. Expand
Acetylcholine‐induced relaxation of peripheral arteries isolated from mice lacking endothelial nitric oxide synthase
TLDR
Data indicate arteries from eNOS (−/−) mice demonstrate a supersensitivity to exogenous NO, and that acetylcholine‐induced vasorelaxation of femoral and mesenteric vessels from e NOS −/−] mice is mediated by an endothelium‐derived factor that has properties of an EDHF but is neither NO nor prostacyclin.
