Reactive oxygen species- (ROS-) mediated injury has been implicated in several inflammatory disorders, including inflammatory bowel disease (IBD). NADPH oxidases (NOXs) are the major source of endogenous ROS. Here, we investigated the role of NOXs derived-ROS in a mouse model of colitis induced by
NADPH oxidases are important sources of vascular superoxide, which has been linked to the pathogenesis of atherosclerosis. Previously we demonstrated that the Nox4 subunit of NADPH oxidase is a critical catalytic component for superoxide production in quiescent vascular smooth muscle cells. In this
Increased reactive oxygen species by the activation of NADPH oxidase (NOX) contributes to the development of diabetic complications. Apocynin, a NOX inhibitor, increases sciatic nerve conductance and blood flow in diabetic rats. We investigated potential protective effect of apocynin in rat diabetic
OBJECTIVE
To investigate whether apocynin, 1-(4-hydroxy-3-methoxyphenyl)ethanone, is able to diminish inflammation-induced cartilage destruction in rheumatoid arthritis (RA), studied in a human in vitro model.
METHODS
Apocynin was added to cultures of RA peripheral blood mononuclear cells (PBMNC).
In the Sabra rat, oxidative stress (OS) and inflammation precede the development of hypertension. Inhibition of the phagocytic NADPH oxidase attenuates the rise in blood pressure. The present study was set to identify possible priming agents for this enzyme and to test the hypothesis that the
OBJECTIVE
to evaluate the rheumatoid synovial cell capacity to produce superoxide anion in response to interleukin-1beta (IL-1beta) and tumour necrosis factor-alpha (TNF-alpha), and to study the NADPH oxidase involvement in this production.
METHODS
Synovial cells obtained from 7 rheumatoid arthritis
We investigated the effects of apocynin on high-fat diet- (HFD-) induced insulin resistance in C57BL/6 mice. After 12 weeks of HFD, the mice that exhibited insulin resistance then received 5 weeks of apocynin (2.4 g/L, in water). Following apocynin treatment, fasting glucose, insulin, and glucose
BACKGROUND
Apocynin suppresses the generation of reactive oxygen species (ROS) that are implicated in ventilator-induced lung injury (VILI). We thus hypothesized that apocynin attenuates VILI.
METHODS
VILI was induced by mechanical ventilation with tidal volume (V(t)) of 15 ml/kg in isolated and
We investigated how docosahexaenoic acid (DHA) regulated tumor necrosis factor-alpha (TNF-α)-induced senescence and dysfunction in endothelial cells (EC). We used RT-PCR to examine the expression of several genes related to senescence and dysfunction in EC. TNF-α-induced p21 protein levels were
Reactive oxygen and nitrogen species are among the crucial mediators in the development of the pathological inflammatory process in the lungs and contribute to the damage of lung epithelium. The aim of the present study was to evaluate the potential of selected antioxidants or inhibitors of NADPH
The aim of this study was to investigate the effects of apocynin, a NADPH (nicotinamide adenine dinucleotide phosphate)-oxidase inhibitor, in diabetic rats with nephropathy induced by contrast medium (CIN). Diabetes was induced in male Wistar rats by a single dose of streptozotocin (60 mg/kg i.v.).
Apocynin suppresses the generation of reactive oxygen species (ROS) that are implicated in ischemia-reperfusion (I/R) lung injury. We thus hypothesized that apocynin attenuates I/R. Furthermore, we explored the mechanisms by which apocynin may attenuate I/R. I/R was induced in an isolated and
The aim of this study was to investigate whether a nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) inhibitor, apocynin, reduces reactive oxygen species (ROS) production, suppresses the nuclear factor κB (NF-κB) pathway, attenuates lung injury, and improves survival in rat
This study compared the effects of intracellular pathway inhibitors on tumor necrosis factor-alpha (TNF-alpha) release from human monocytes. Cells were stimulated with peptidoglycan (PG) from Staphylococcus epidermidis or with Escherichia coli lipopolysaccharide (LPS), both in the presence of 10%
OBJECTIVE
To investigate the effect of advanced oxidation protein products (AOPP) on the secretion of tumor necrosis factor alpha eTNFalphae in monocytes and its possible mechanism.
METHODS
Human monocyte cell line THP-1 and peripheral blood monocytes were incubated with AOPP-bovine serum
