NITRIC OXIDE AND VERTEBRATE DEVELOPMENT

Nitric oxide and the bioactivities

Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...

Nitric oxide selectively tunes inhibitory synapses to modulate vertebrate locomotion.

We have explored the possible modulation by nitric oxide (NO) of inhibitory synaptic transmission mediated by either glycine or GABA during episodes of rhythmic fictive swimming in postembryonic Xenopus laevis tadpoles. Extracellular ventral-root recordings suggest a stage-dependent increase in the reliability and extent of the NO donor S-nitroso-n-acetylpenicillamine (SNAP; 0.1-1 mm) to inhibi...

The Effect of Nitric Oxide on Mouse Pre-Implantation Embryo Development and Apoptosis

Clinical studies have shown that in pathological conditions such as endometriosis and reproductive tract infection (male and female) there is an activation status of macrophages that produce large quantities of nitric oxide (NO) in addition to other effector molecules. Large amounts of NO may have embryotoxic roles and produce infertility. This study was designed to evaluate the effect of diffe...
