Regulation of boar sperm functionality by the nitric oxide synthase/nitric oxide system

Differential Regulation of Nitric Oxide

Regulation of the nitric oxide system in human adipose tissue.

Nitric oxide (NO) is involved in adipose tissue biology by influencing adipogenesis, insulin-stimulated glucose uptake, and lipolysis. The enzymes responsible for NO formation in adipose cells are endothelial NO synthase (eNOS) and inducible NO synthase (iNOS), whereas neuronal NO synthase (bNOS) is not expressed in adipocytes. We characterized the expression pattern and the influence of adipog...

Nitric oxide regulation of protein trafficking in the cardiovascular system.

Nitric oxide (NO) is a second messenger with diverse roles in the cardiovascular system, such as inhibiting thrombosis and limiting vascular inflammation. One mechanism by which NO modulates such disparate physiological processes is by regulating protein trafficking within cells. NO inhibits exocytosis of endothelial granules which would otherwise trigger inflammation. NO also blocks platelet s...

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...
