NADPH oxidase-mediated redox signaling promotes oxidative stress resistance and longevity through memo-1 in C. elegans

eLife, 2017
Transient increases in mitochondrially-derived reactive oxygen species (ROS) activate an adaptive stress response to promote longevity. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidases produce ROS locally in response to various stimuli, and ...

Nuclear factor-kappaB regulates the transcription of NADPH oxidase 1 in human alveolar epithelial cells

BMC Pulmonary Medicine, 2021
Objective Acute lung injury (ALI) is characterized by inflammation and oxidative stress. Nuclear factor-kappaB (NF-κB) mediates the expression of various inflammation-related genes, including the NADPH oxidase family.

An Aggregation‐Induced Polymerization Poly(Disulfide)‐Drug Nanoplatform for Autoimmune Uveitis Therapy via Inhibiting the cGAS‐STING Pathway

Advanced Science, EarlyView.
A cationic poly(disulfide)‐drug nanoplatform (LA/DexP) was developed to treat experimental autoimmune uveitis (EAU). With potent blood‐retinal barrier penetrability, LA/DexP releases DSP in response to high ROS and scavenges cfDNA to inhibit the cGAS‐STING signaling pathway.

Mechanisms of Activation of NADPH Oxidases

Japanese Journal of Infectious Diseases, 2004
The members of the NOX family of enzymes are expressed in a variety of tissues and serve a number of functions. There is a high level of conservation of primary protein sequence, as well as functional features, although specialized responses are beginning to emerge.

NADPH Oxidase Deficiency: A Multisystem Approach [PDF]

Oxidative Medicine and Cellular Longevity, 2017
The immune system is a complex system able to recognize a wide variety of host agents, through different biological processes. For example, controlled changes in the redox state are able to start different pathways in immune cells and are involved in the killing of microbes.

Chlorination‐Driven BODIPY Fluorescent Probes for the Selective Monitoring of Myeloperoxidase Activity in Cells and Inflamed Mouse Models

Angewandte Chemie, EarlyView.
A meso‐carboxamide‐substituted BODIPY fluorescent probe reports myeloperoxidase (MPO) activity via electrophilic chlorination by MPO‐derived HOCl, generating a highly emissive chlorinated product with a ca. 40 nm bathochromic shift. Applications in quantitative MPO assays, cellular imaging of MPO‐derived HOCl, redox‐dependent discrimination of cancer ...

Diphenyleneiodonium, an inhibitor of NOXes and DUOXes, is also an iodide-specific transporter

FEBS Open Bio, 2014
NADPH oxidases (NOXes) and dual oxidases (DUOXes) generate O2.− and H2O2. Diphenyleneiodonium (DPI) inhibits the activity of these enzymes and is often used as a specific inhibitor.

The Importance of NADPH Oxidases and Redox Signaling in Angiogenesis

, 2017
Eukaryotic cells have to cope with the constant generation of reactive oxygen species (ROS). Although the excessive production of ROS might be deleterious for cell biology, there is a plethora of evidence showing that moderate levels of ROS are important

Reversing Macrophage Immunometabolic Dysfunction in Prolonged Infections Via a Glutaminolysis‐Fueled Restoration‐Based Hierarchically Selective Therapeutic System

Advanced Science, EarlyView.
A hierarchically selective immunotherapeutic nanoplatform, mGls@HEV‐MTP, selectively restores macrophage immunocompetence through GLS1‐mediated restoration of glutaminolysis‐fueled anaplerosis. Concurrently, it renders Staphylococcus aureus (S. aureus) more readily recognizable to the metabolically reprogrammed macrophages, thereby facilitating ...
