General description

Nω-Nitro-L-argininemethyl ester hydrochloride or L -NAME HCl, ananalog of arginine, inhibits NO production. It has multiple effects on thevascular system. Inhibits relaxation induced by acetylcholine and induces anincrease in arterial blood pressure. Abolishes lecithinized superoxidedismutase induced vasodilation when used to pretreat aortic ring preparationsof mice. Induces leukocyte adhesion and increases microvascular fluid andprotein fluxes and permeability. It has also been used in many studies oflearning and memory.

Application

Nω-Nitro-L-arginine methyl ester hydrochloride has been used:
  • to study the effects of brain-derived neurotrophic factor against neurotoxicity in rat cortical neurons
  • to study its effect on far-infrared (FIR) enhanced microcirculation of rat skin
  • to study its effect on leptin-induced regulation of myokine fibronectin type III domain containing five/irisin in murine myocytes and fat cells
  • to study its effect on the levels of arginine vasopressin and neuronal nitric oxide synthase mRNA levels in hypothalamic paraventricular nucleus and supraoptic nucleus of rat

We investigated the role of nitric oxide (NO) in learning and memory formation in a radial maze test, by using the NO synthase (NOS) inhibitors, NG-nitro-L-arginine methyl ester (L-NAME) and 7-nitroindazole (7-NI), and an NO precursor, L-arginine. Rats were trained

We recently demonstrated that inhibitors of nitric oxide (NO) production cause a dramatic increase in leukocyte adherence and emigration in postcapillary venules. The objective of this study was to assess whether inhibition of NO production leads to vascular protein leakage

Sustained, indolent immune injury of the vasculature of a heart transplant limits long-term graft and recipient survival. This injury is mitigated by a poorly characterized, maladaptive repair response. Vascular endothelial cells respond to proangiogenic cues in the embryo by differentiation

Endothelial activation and apoptosis release membrane-shed microparticles (EMP) that emerge as important biological effectors. Because laminar shear stress (SS) is a major physiological regulator of endothelial survival, we tested the hypothesis that SS regulates EMP release. EMP levels were quantified
