Three distinct mechanisms generate oxygen free radicals in neurons and contribute to cell death during anoxia and reoxygenation [PDF]

, 2007
Ischemia is a major cause of brain damage, and patient management is complicated by the paradoxical injury that results from reoxygenation. We have now explored the generation of reactive oxygen species (ROS) in hippocampal and cortical neurons in ...

NADPH Oxidases and Their Role in Atherosclerosis [PDF]

Biomedicines, 2020
The current view on atherosclerosis positions it as a multifactorial disorder that results from the interplay between lipid metabolism disturbances and inflammatory processes. Oxidative stress is proven to be one of the initiating factors in atherosclerosis development, being implicated both in the inflammatory response and in atherogenic modifications

Signaling through NADPH oxidases [PDF]

, 2006
Vascular remodeling processes are characterized by increased proliferation of vascular cells and a prothrombotic state. Coagulation factors and vasoactive peptides have been suggested to contribute to these processes.

NOX4 exacerbates Parkinson’s disease pathology by promoting neuronal ferroptosis and neuroinflammation

Neural Regeneration Research
Parkinson’s disease is primarily caused by the loss of dopaminergic neurons in the substantia nigra compacta. Ferroptosis, a novel form of regulated cell death characterized by iron accumulation and lipid peroxidation, plays a vital role in the death of ...

Exercise Training Ameliorates Renal Oxidative Stress in Rats with Chronic Renal Failure

Metabolites, 2022
In patients with chronic kidney disease, exercise training with moderate intensity protects renal function and improves mortality. However, the mechanisms of the renal protective effects of exercise training in chronic kidney disease have not been ...

Roles of NADPH Oxidase in Occurrence of Gastric Damage and Expression of Cyclooxygenase-2 During Ischemia/Reperfusion in Rat Stomachs

Journal of Pharmacological Sciences, 2009
NADPH oxidase is an enzyme that converts molecular oxygen into reactive oxygen species, which cause severe damage in several organs. Cyclooxygenase (COX)-2 is an inducible enzyme that is important in gastric mucosal defense and repair processes.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Expression and modulation of an NADPH oxidase in mammalian astrocytes [PDF]

, 2005
Amyloid β peptides generate oxidative stress in hippocampal astrocytes through a mechanism sensitive to inhibitors of the NADPH oxidase [diphenylene iodonium (DPI) and apocynin].

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Regulation of the microglial NADPH oxidase by neurotransmitters: implications for microglial – neuronal interactions [PDF]

, 2012
Neurotransmitter dysregulation and reactive oxygen species (ROS) are a hallmark of neurodegenerative disease. Microglia, the immune cells of the CNS, express three NADPH oxidase isoforms (Nox1, Nox2 and Nox4), which produce superoxide that is used as an ...
