We have assessed the stoichiometry of the nitric oxide (NO) synthase reaction by using a novel e.p.r. technique. NO generated by crude and partially purified NO synthase from endothelial cells and Escherichia coli-lipopolysaccharide-activated macrophages was trapped by a ferrous diethyldithiocarbamate complex dispersed in yeast. The paramagnetic ferrous mononitrosyl dithiocarbamate complex form...
Calmodulin-dependent nitric-oxide synthase from bovine brain and GH3 pituitary cells is inhibited by imidazole, 1-phenylimidazole, 2-phenylimidazole, and 4-phenylimidazole, with half-maximal inhibition occurring at 200, 25, 160, and 600 microM concentrations of inhibitor, respectively. Imidazole inhibits the maximal velocity of citrulline formation by the enzyme, but does not alter the concentr...
Diabetes mellitus complicates pregnancies, leading to diseases in adult life in the offspring. Asymmetric dimethylarginine (ADMA) is increased in diabetes mellitus, kidney disease, and hypertension. We tested whether maternal diabetes causes increased ADMA in rats, resulting in kidney disease and hypertension in the adult offspring, and whether these can be prevented by maternal citrulline supp...
The role of NOS2 and NOS3 in renal protein and arginine metabolism during early endotoxemia in mice.
Previously, we observed an enhanced renal protein synthesis and increased de novo arginine production in the early response to endotoxemia in wild-type Swiss mice (Hallemeesch MM, Soeters PB, and Deutz NE. Am J Physiol Renal Physiol 282: F316-F323, 2002). To establish whether these changes are regulated by nitric oxide (NO) synthesized by NO synthase isoforms NOS2 and NOS3, we studied C57BL6/J ...
Low plasma citrulline levels have been associated with a reduction of functional gut mass in various clinical situations. In critically ill patients, citrulline variations are tricky to interpret because of sepsis, vascular abnormalities, and multiple organ failure. In the previous issue of Critical Care, Ware and colleagues made an important contribution by demonstrating that very low citrulli...
