Metformin Restores the Penile Expression of Nitric Oxide Synthase in High-Fat–Fed Obese Rats
AMP-activated protein kinase penile tissue
2008/12/24
Obesity is a well-known risk factor for erectile dysfunction, which is associated with reduced penile nitric oxide synthase (NOS) expression. Recently it was reported that metformin activates AMP...
Paracrine Modulation of Androgen Synthesis in Rat Leydig Cells by Nitric Oxide
Macrophage testosterone DNA gene array nitric oxide synthase S-nitrosoglutathione L-NG-nitro-arginine methyl ester L-NG-monomethyl-arginine
2008/12/23
The free radical nitric oxide (NO), generated through the oxidation of L-arginine to L-citrulline by NO synthases (NOSs), has been shown to inhibit steroidogenic pathways. NOS isoforms are known...
Overexpression of Endothelial Nitric Oxide Synthase in Transgenic Mice Accelerates Testicular Germ Cell Apoptosis Induced by Experimental Cryptorchidism
Immunoblotting TUNEL spermatocytes spermatids spermatogonia
2008/12/23
Surgical induction of cryptorchidism in experimental animals causes testicular germ cell apoptosis and infertility. The mechanisms of germ cell apoptosis have been associated with oxidative stress o...
Glu298Asp Endothelial Nitric Oxide Synthase Polymorphism Is a Risk Factor for Erectile Dysfunction in the Mexican Mestizo Population
Angiotensin-converting enzyme endothelial dysfunction impotence
2008/12/22
Penile erection depends on the balanced action between antagonist vasoactive molecules such as nitric oxide (NO) and angiotensin. Endothelial nitric oxide synthase (eNOS) and angiotensin-convertin...
Effect of Chronic Ischemia on Constitutive and Inducible Nitric Oxide Synthase Expression in Erectile Tissue
Erectile dysfunction atherosclerosis blood flow oxygen tens
2008/12/22
Arterial occlusive disease is one of the leading causes of organic erectile dysfunction (ED). Recent studies have shown that the incidence of cardiovascular disease closely correlates with the preva...
Role of Nitric Oxide Concentrations on Human Sperm Motility
Male infertility spermatozoa motility asthenozoospermia
2008/12/22
Nitric oxide (NO) is a free radical generated from the oxidation of L-arginine to L-citrulline by 3 isoforms of reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent NO synthases. Se...
Nitric Oxide Regulation of Penile Erection: Biology and Therapeutic Implications
Nitric Oxide Regulation Penile Erection Biology Therapeutic Implications
2008/12/15
For approximately a decade now, substantial evidence has accrued supporting nitric oxide (NO) as the central component of a major signal transduction system that acts in the penis to mediate the erect...
Noncholinergic penile erection in mice lacking the gene for endothelial nitric oxide synthase
Noncholinergic penile erection gene endothelial nitric oxide synthase
2008/12/1
With the current understanding that nitric oxide (NO) mediates penile erection, the endothelial isoform of NO synthase (eNOS) has been implicated in this function. We undertook this study applying t...
