α-Lipoic Acid Inhibits Helicobacter pylori-Induced Oncogene Expression and Hyperproliferation by Suppressing the Activation of NADPH Oxidase in Gastric Epithelial Cells

Mediators of Inflammation, 2014
Hyperproliferation and oncogene expression are observed in the mucosa of Helicobacter pylori- (H. pylori-) infected patients with gastritis or adenocarcinoma. Expression of oncogenes such as β-catenin and c-myc is related to oxidative stress.

Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

Advanced Science, EarlyView.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

H2O2‐Activated Serotonin Precursor Probe for Mapping Neuronal Redox Homeostasis Reveals 5‐HT Interactions with Neighboring Proteins Under Oxidative Stress

Advanced Science, EarlyView.
HOP, an innovative ICT‐based fluorescent probe, visualizes H2O2 in stressed neurons while locally releasing serotonin (5‐HT) for real‐time protein interaction mapping. Its unique tandem sensing and labeling strategy reveals 5‐HT's role under oxidative stress, offering a powerful tool for neurophysiological research and therapeutic discovery.

Residual NADPH Oxidase Activity and Isolated Lung Involvement in X-Linked Chronic Granulomatous Disease

Case Reports in Pediatrics, 2012
Chronic granulomatous disease (CGD) is characterized by inherited immune defects resulting from mutations in the NADPH oxidase complex genes. The X-linked type of CGD is caused by defects in the CYBB gene that encodes gp91-phox, a fundamental component ...

Cholesterol: A modulator of the phagocyte NADPH oxidase activity - A cell-free study

Redox Biology, 2014
The NADPH oxidase Nox2, a multi-subunit enzyme complex comprising membrane and cytosolic proteins, catalyzes a very intense production of superoxide ions O2•−, which are transformed into other reactive oxygen species (ROS).

Phytophthora Disrupts Plant Immunity by Manipulating Nitric Oxide Homeostasis Through GSNOR Inhibition

Advanced Science, EarlyView.
Phytophthora capsici effector PcRD18 targets tomato GSNOR to disrupt NO homeostasis, promoting S‐nitrosylation of immune proteins like RBOHD. This suppresses ROS bursts and promotes pathogen infection. Mutation of the PcRD18‐binding sites of GSNOR avoids pathogen manipulation and offers a strategy to enhance crop resistance. Abstract Nitric oxide (NO),

ABCG1 Attenuates Oxidative Stress Induced by H2O2 through the Inhibition of NADPH Oxidase and the Upregulation of Nrf2-Mediated Antioxidant Defense in Endothelial Cells

Analytical Cellular Pathology, 2020
Summary. Oxidative stress is an important factor that is related to endothelial dysfunction. ATP-binding cassette transporter G1 (ABCG1), a regulator of intracellular cholesterol efflux, has been found to prevent endothelial activation in vessel walls ...

Covalent Organic Frameworks‐Delivered Reuterin Drives Trained Immunity in Tumor‐Associated Macrophages to Enhance Melanoma Immunotherapy via Glycerophospholipid Metabolism

Advanced Science, EarlyView.
Covalent organic framework (COF)‐reuterin induces trained immunity in tumor‐associated macrophages, promoting the generation of nitric oxide and reactive oxygen species, thereby enhancing the antitumor immune response. Additionally, COF‐Reuterin directly kills tumor cells while simultaneously eradicating pathogenic intratumoural bacteria.
