The nicotinamide adenine dinucleotide phosphate (NADPH) oxidase expressed in phagocytes is a multi-subunit enzyme complex that generates superoxide (O2 (.-)). This radical is an important precursor of hydrogen peroxide (H2O2) and other reactive oxygen species needed for microbicidal activity during innate immune responses. Inherited defects in NADPH oxidase give rise to chronic granulomatous di...
The resolved flavoprotein and cytochrome b55g components of the NADPH dependent 0 -. further f generating oxidase from human neutrophils were the subject of stu y. The resolved flavoprotein, depleted of cytochrome bssg, was reduced by NADPH under anaerobic conditions and reoxidized by oxygen. NADPH dependent 02-. generation by the resolved flavoprotein fraction was not detectable, however it wa...
Pentane was measured in a mixture of guinea pig liver microsomes and carbontetrachloride (CCl4) in the presence of nicotineamide adenine dinucleotide phosphate (NADPH) and under anaerobic conditions by gas chromatography. Pentane of 0.2 pmol/mg protein/min was formed in the presence of NADPH without CCl4. Pentane formation increased to 2.0 pmol/mg protein/min in the presence of CCl4 and NADPH. ...
In order to analyze the effect of OC kappa in redox status, photosynthesis, basal metabolism and growth in Eucalyptus globulus, trees were treated with water (control), with OC kappa at 1 mg mL(-1), or treated with inhibitors of NAD(P)H, ascorbate (ASC), and glutathione (GSH) syntheses and thioredoxin reductase (TRR) activity, CHS-828, lycorine, buthionine sulfoximine (BSO), and auranofin, resp...
Crude extracts of pea shoots (Pisum sativum) catalyzed oxidized glutathione (GSSG)-dependent oxidation of NADPH which was attributed to NADPH-specific glutathione reductase. The pH optimum was 8 and the K(m) values for GSSG and NADPH were 23 mum and 4.9 mum, respectively. Reduced glutathione (GSH) inhibited the reaction. Crude extracts also catalyzed NADPH-dependent reduction of GSSG; the ratio...
This study aimed to assess the antioxidant effects of rutin on methotrexate-induced hepatic oxidative stress. Wistar Albino rats (n=24) were separated into 4 groups: control group (C); methotrexate (M, 20 mg/kg, single dose) group; (R, 50 mg/kg/day, for fifteen days) and + [MR, (20 (50 days)] group. Rats sacrificed sixteenth day liver tissues removed. The glucose-6-phosphate dehydrogenase (G6PD...
BACKGROUND AND PURPOSE We examined the importance of NADPH-oxidase in reactive oxygen species production in cerebral arteries and its effect on vascular tone in vivo. Furthermore, we investigated whether chronic hypertension affects function or expression of this enzyme in cerebral vessels. METHODS Superoxide generation was detected in isolated rat basilar arteries with the use of lucigenin-e...
Cytochrome P-450 LM2 reduction was measured at a series of NADPH concentrations in the absence of substrate and in the presence of 1 mM benzphetamine. In the absence of substrate reduction could be described as a biphasic process with 55% of the reaction occurring in the first phase (at 20 microM NADPH). When benzphetamine was present, the fraction of the reaction occurring in the first phase w...
