NADPH oxidase-dependent production of reactive oxygen species induces endoplasmatic reticulum stress in neutrophil-like HL60 cells. [PDF]

PLoS ONE, 2015
Reactive oxygen species (ROS) primarily produced via NADPH oxidase play an important role for killing microorganisms in neutrophils. In this study we examined if ROS production in Human promyelocytic leukemia cells (HL60) differentiated into neutrophil ...

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

Advanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

Generation of reactive oxygen species in 1-methyl-4-phenylpyridinium (MPP+) treated dopaminergic neurons occurs as an NADPH oxidase-dependent two-wave cascade

Journal of Neuroinflammation, 2011
Background Reactive oxygen species (ROS), superoxide and hydrogen peroxide (H2O2), are necessary for appropriate responses to immune challenges. In the brain, excess superoxide production predicts neuronal cell loss, suggesting that Parkinson's disease ...

Organic AIE Nanoradiosensitizer Potentiates X‐Ray Triggered Continuous Reactive Oxygen Species Generation for Potent Cancer Radioimmunotherapy

Advanced Materials, EarlyView.
Herein, a glutathione‐responsive system (named THN) is prepared for X‐ray‐triggered sustained ROS generation for efficient antitumor immunotherapy. The double‐promoting ROS generation of THN induced massive immunogenic cancer cell death and polarized M2 macrophages into the M1 phenotype for enhanced antitumor immunotherapy.

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 ...

Inhibition of NADPH oxidase activation in oligodendrocytes reduces cytotoxicity following trauma. [PDF]

PLoS ONE, 2013
Spinal cord injury is a debilitating neurological disorder that initiates a cascade of cellular events that result in a period of secondary damage that can last for months after the initial trauma.

NOX2 Contributes to High‐Frequency Outer Hair Cell Vulnerability in the Cochlea

Advanced Science, EarlyView.
This study first identifies NOX2 as a differentially expressed gene related to oxidative damage in the apical and basal turns through single‐cell RNA sequencing. NOX2 gene knockout mitigates OHCs damage caused by neomycin and noise and enhances Nrf2 expression and nuclear translocation.

Succinate Dehydrogenase Subunit A (SDHA) Mediated Microglia Extracellular Traps Formation Participating in Cerebral Ischemic Reperfusion Injury

Advanced Science, EarlyView.
This study investigates the mechanism of succinate dehydrogenase (SDH)‐mediated succinate oxidation in microglia extracellular traps (MiETs) formation and neuronal injury after cerebra I/R injury. Dimethyl malonate (DMM), a competitive SDH inhibitor, could reduce MiETosis by inhibiting succinate oxidation and mtROS production during reperfusion ...

NADPH oxidases in the arbuscular mycorrhizal symbiosis [PDF]

Plant Signaling & Behavior, 2016
Plant NADPH oxidases are the major source of reactive oxygen species (ROS) that plays key roles as both signal and stressor in several plant processes, including defense responses against pathogens. ROS accumulation in root cells during arbuscular mycorrhiza (AM) development has raised the interest in understanding how ROS-mediated defense programs are

Natural Allelic Variations in IbCHYR1–IbZnFR Complex Regulate Fusarium Root Rot Resistance in Sweet Potato

Advanced Science, EarlyView.
FfRlpA2, a conserved Fusarium effector, functions as a protease inhibitor by hijacking the E3 ubiquitin ligase IbCHYR1 to degrade the resistance factor IbZnFR, thereby promoting Fusarium pathogenicity. Conversely, the high dosage Pro::IbZnFRHap2 allele was associated with resistance to root rot disease.
