A Multifarious NADPH Oxidase
Nox4, one of the 7 isoforms of the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase family that generate reactive oxygen species, was first identified in the early 2000s in kidneys.1 Nox4 was originally described as an oxygen sensor and regulator of kidney cell growth and because of its renal abundance was termed “renox.”1 It soon became evident that Nox4 has a ubiquitous distributio...
متن کاملInhibition of NADPH Oxidase by Apocynin Attenuates Progression of Atherosclerosis
Of the multiple sources of reactive oxygen species (ROS) in the blood vessel, NADPH oxidases are the primary source. Whereas several studies have implicated NADPH oxidases in the initiation of atherosclerosis, their roles in disease progression are incompletely understood. Our objective was to determine the potential clinical relevance of inhibiting NADPH oxidase in established atherosclerosis....
متن کاملInhibition of human vascular NADPH oxidase by apocynin derived oligophenols.
Enzymatic oxidation of apocynin, which may mimic in vivo metabolism, affords a large number of oligomers (apocynin oxidation products, AOP) that inhibit vascular NADPH oxidase. In vitro studies of NADPH oxidase activity were performed to identify active inhibitors, resulting in a trimer hydroxylated quinone (IIIHyQ) that inhibited NADPH oxidase with an IC(50)=31nM. Apocynin itself possessed min...
متن کاملThe Importance of Myeloperoxidase in Apocynin-Mediated NADPH Oxidase Inhibition
Apocynin is widely used as an inhibitor of the NADPH oxidase. Since myeloperoxidase (MPO) has been considered as essential for the mechanism of action of apocynin, here we used cells with different levels of MPO and compared their sensitivity to apocynin. HL-60 cells were differentiated with DMSO or IFN γ /TNF α and compared with peripheral mononuclear (PBMC) and polymorphonuclear cells (PMN). ...
متن کاملInhibition of NADPH Oxidase May Promote Exercise Endurance
Repetitive muscle contraction is associated with increased superoxide production in skeletal muscle. 1-8 There is considerable evidence that muscle fatigue during prolonged exercise is associated with oxidant stress in muscle fibers, and that this stress is indeed partially responsible for the fatigue. Thus, pharmacological strategies which depress the antioxidant defenses of muscle fibers acce...
