Regulation of protein expression by L-arginine in endothelial cells.
L-Arginine is a conditionally essential amino acid for humans and plays an important role in the regulation of cardiovascular function and antioxidative defense. Previous studies have focused on the important role of L-arginine as a physiological precursor in the generation of nitric oxide and polyamines in endothelial cells (cells that line the interior surface of blood vessels). Because of th...
متن کاملInhibition of L-Arginine Metabolizing Enzymes by L-Arginine-Derived Advanced Glycation End Products
N(omega)-Carboxymethyl-arginine (CMA), N(omega)-carboxyethyl-arginine (CEA) and N(delta)-(5-hydro-5-methyl-4-imidazolon-2-yl)-ornithine (MG-H1) have been identified as L-arginine-derived advanced glycation end products (AGEs) formed by non-enzymatic reactions between reducing sugars such as glucose and amino groups in proteins. These AGEs are structurally analogous to endogenous inhibitors of n...
متن کاملRegulation of macrophage functions by L-arginine
Sites of inflammation with prominent macrophage infiltration, such as wounds and certain tumors, are uniquely deficient in free arginine. The effects of arginine availability on macrophage physiology were investigated. When cultured in media containing less than 0.1 mM L-arginine, rat resident peritoneal macrophages exhibited enhanced spreading, tumor cytotoxicity, superoxide production, phagoc...
متن کاملL-Arginine Monograph
Introduction L-Arginine is a semi-essential amino acid involved in numerous areas of human physiology, including production of nitric oxide (NO) – a key messenger molecule involved in vascular regulation, immune activity, and endocrine function. Arginine is also involved in protein production, wound healing, erectile function, and fertility. Arginine is not considered essential because humans c...
متن کاملL-Arginine Metabolic Pathways
The present review will give an overview of the biochemistry and metabolism of L-arginine focusing on the mechanisms which may either provide or limit cellular availability of this amino acid for nitric oxide synthases and arginase / polyamine pathway and describe possible interactions between these pathways. In addition, emerging species differences in the expression and role of arginases are ...
