Human skin fibroblasts isolated in vitro from subjects carrying the Mediterranean variant of glucose-6-phosphate dehydrogenase exhibit an 85% decrease of this enzymatic activity. There is a 26% and a 94% decrease of the hexose monophosphate shunt and of the reduced nicotinamide adenine dinucleotide phosphate/nicotinamide adenine dinucleotide phosphate ratio, respectively. Incubation with 0.1 mM...
Human erythrocyte glucose 6-phosphate dehydrogenase (o-glucose 6-phosphate :nicotinamide adenine dinucleotide phosphate oxidoreductase, EC 1.1.1.49) was purified by column chromatography with diethylaminoethyl cellulose, calcium phosphate gel, carboxymethyl cellulose, diethylaminoethyl Sephadex, and carboxymethyl Sephadex. A homogeneous preparation was obtained in over-all yield of about 50%. T...
Mercurous ion (Hg(+))-dependent reduced nicotinamide adenine dinucleotide phosphate oxidation was demonstrated in an extract from cells of Escherichia coli W2252 that bear R factor.
Electron spin resonance measurements were performed for the reactions of some endogenous photosensitizers (flavin mononucleotide or flavin adenine dinucleotide or folic acid or β-nicotinamide adenine dinucleotide or β-nicotinamide adenine dinucleotide phosphate or pyridoxal-5'-phosphate or urocanic acid) with oleic acid under the ultraviolet light A irradiation using α-(4-pyridyl-1-oxide)-N-ter...
Pulmonary arterial hypertension (PAH) is a debilitating and deadly disease with no known cure. Heart failure is a major comorbidity and a common cause of the premature death of patients with PAH. Increased asymmetrical right ventricular hypertrophy and septal wall thickening compress the left ventricular cavity and elicit diastolic heart failure. In this study, we used the Sugen5416/hypoxia/nor...
Nicotiniamide adenine dintucleotide plhosphate-specific isocitrate dehydrogenase was extracted from etiolated pea (Pisurn satirum L.) seedlings and was purified 65-fold. The puirified enzyme exhibits one predoniinant protein band by pol acrylamide gel electrophoresis, w-hich corresponds to tiie dehy-drogenase activity as imieasuired by the nitro bluie tetrazolium technique. The reaction is read...
Central sympathoexcitation is involved in the pathogenesis of salt-sensitive hypertension. We have suggested that oxidative stress in the brain modulates the sympathetic regulation of arterial pressure. Thus, we investigated whether oxidative stress could mediate central sympathoexcitation in salt-sensitive hypertension. Five- to 6-week-old male Dahl salt-sensitive rats and salt-resistant rats ...
We demonstrated recently that superoxide anion levels are elevated in prevertebral sympathetic ganglia of deoxycorticosterone acetate-salt hypertensive rats and that this superoxide anion is generated by reduced nicotinamide-adenine dinucleotide phosphate oxidase. In this study we compared the reduced nicotinamide-adenine dinucleotide phosphate oxidase enzyme system of dorsal root ganglion (DRG...
The role of angiotensin II and reactive oxygen species in the exacerbation of diastolic heart failure is unknown. We examined the therapeutic effect of angiotensin blockade on hypertensive diastolic heart failure, focusing on the role of xanthine oxidoreductase and reduced nicotinamide-adenine dinucleotide phosphate oxidase, major enzymes producing reactive oxygen species. Dahl salt-sensitive h...
Reactive oxygen species (ROS) in the brain are thought to contribute to the neuropathogenesis of hypertension by enhancing sympathetic nervous system activity. The nucleus tractus solitarius (NTS), which receives afferent input from baroreceptors, has an important role in cardiovascular regulation. reduced nicotinamide-adenine dinucleotide phosphate oxidase is thought to be a major source of RO...
