Coronary hemodynamics in endothelial NO synthase knockout mice.
For the specific analysis of endothelial NO synthase (eNOS) function in the coronary vasculature, we generated a mouse homozygous for a defective eNOS gene (eNOS-/-). Western blot as well as immunohistochemical staining revealed the absence of eNOS protein in eNOS-/- mice. Aortic endothelial cells derived from eNOS-/- mice displayed only background levels of NOx formation compared with wild-typ...
متن کاملContribution of 20-HETE to augmented myogenic constriction in coronary arteries of endothelial NO synthase knockout mice.
Previous studies suggested an important role for 20-HETE in the regulation of myogenic responses. Thus, pressure-diameter relationships were investigated in isolated, cannulated coronary arteries (approximately 100 microm) from male endothelial NO synthase knockout (eNOS-KO) and wild-type (WT) mice. All arteries constricted in response to step increases in perfusate pressure from 20 to 100 mm H...
متن کاملIncreased salt-sensitivity in endothelial nitric oxide synthase-knockout mice.
BACKGROUND Although impaired nitric oxide production contributes importantly to salt-sensitivity, the role of the endothelial isoform of nitric oxide synthase (eNOS) has received little attention. In the present study we compared the effects of a high-salt diet on the blood pressure response of eNOS knockout (eNOS-/-) and control (eNOS+/+) mice. METHODS Mean arterial pressure (MAP), heart rat...
متن کاملNeuronal and endothelial nitric oxide synthase gene knockout mice.
Targeted disruption of the neuronal nitric oxide synthase (nNOS) and endothelial nitric oxide synthase (eNOS) genes has led to knockout mice that lack these isoforms. These animal models have been useful to study the roles of nitric oxide (NO) in physiologic processes. nNOS knockout mice have enlarged stomachs and defects in the inhibitory junction potential involved in gastrointestinal motilit...
متن کاملNormal vascular development in mice deficient in endothelial NO synthase: possible role of neuronal NO synthase.
PURPOSE Nitric oxide formation by nitric oxide synthase (NOS) has been implicated in vascular injury and retinal neovascularization during oxygen-induced retinopathy. However, the role of NOS in normal retinal vascular development and growth has not been studied. The purpose of these experiments was to characterize the expression of NOS in relation to vascular development and to determine the e...
