Superoxide dismutase analog (Tempol: 4-hydroxy-2, 2, 6, 6-tetramethylpiperidine 1-oxyl) treatment restores erectile function in diabetes-induced impotence. [PDF]

open access: yes, 2009
We hypothesized that the administration of the superoxide dismutase (SOD) mimetic Tempol (4-hydroxy-2, 2, 6, 6-tetramethylpiperidine 1-oxyl) may reverse diabetes-induced erectile dysfunction. To test this hypothesis, reactive oxygen species-related genes

The role of constitutive nitric‐oxide synthase in regulation of IKKα after ultraviolet irradiation

open access: yesPhotochemistry and Photobiology, EarlyView.
cNOS enhances IKKα expression following UVB exposure by promoting promoter activation, transcriptional elongation, and Ets‐1 stabilization. These actions sustain IKKα levels, reduce UV‐induced skin carcinogenesis, and highlight cNOS as a key protective factor against solar UV damage.

Mechanisms of cell death pathway activation following drug-induced inhibition of mitochondrial complex I

open access: yesRedox Biology, 2015
Respiratory complex I inhibition by drugs and other chemicals has been implicated as a frequent mode of mitochondria-mediated cell injury. However, the exact mechanisms leading to the activation of cell death pathways are incompletely understood.

Pharmacology and clinical drug candidates in redox medicine [PDF]

open access: yes, 2015
SIGNIFICANCE Oxidative stress is suggested to be a disease mechanism common to a wide range of disorders affecting human health. However, so far, the pharmacotherapeutic exploitation of this, for example, based on chemical scavenging of pro-oxidant ...

ANSID: a Solid-Phase Proteomic Approach for Identification and Relative Quantification of Aromatic Nitration Sites

open access: yesFrontiers in Chemistry, 2016
Nitration of tyrosine and other aromatic amino acid residues in proteins occurs in the setting of inflammatory, neurodegenerative and cardiovascular diseases – importantly, this modification has been implicated in the pathogenesis of diverse diseases and

Redox‐regulated signalling of adaptations to contractile activity in skeletal muscle: Implications for age‐related muscle weakness

open access: yesExperimental Physiology, EarlyView.
Abstract Skeletal muscle adaptation to contractile activity is modulated by redox signalling, primarily through reactive oxygen species (ROS) such as hydrogen peroxide (H2O2). Early research framed ROS as deleterious byproducts of exercise, but subsequent studies have established their roles as signalling molecules involved in mitochondrial biogenesis,

Activation of microglial NADPH oxidase is synergistic with glial iNOS expression in inducing neuronal death: a dual-key mechanism of inflammatory neurodegeneration

open access: yesJournal of Neuroinflammation, 2005
Background Inflammation-activated glia are seen in many CNS pathologies and may kill neurons through the release of cytotoxic mediators, such as nitric oxide from inducible NO synthase (iNOS), and possibly superoxide from NADPH oxidase (NOX).

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

open access: yesExperimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Excessive hypercholesterolaemia during pregnancy as a risk factor for endothelial dysfunction in pre‐eclampsia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Excessive hypercholesterolaemia during pregnancy impairs maternal endothelial function, which, in turn, drives the development of pre‐eclampsia and may also contribute to the increased risk of later‐life cardiovascular disease in women.

Calciprotein particle‐induced calcium overload triggers mitochondrial dysfunction in endothelial cells

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Calciprotein particles (CPPs) are small calcium‐ and phosphate‐containing nanoaggregates associated with the development of vascular disease (CVD) in chronic kidney disease (CKD). Previously, we have shown that CPPs induce endothelial cell (EC) dysfunction, possibly contributing to CVD in CKD, but the underlying molecular ...
