Disease Progression Mediated by Egr-1 Associated Signaling in Response to Oxidative Stress [PDF]

open access: yes, 2012
When cellular reducing enzymes fail to shield the cell from increased amounts of reactive oxygen species (ROS), oxidative stress arises. The redox state is misbalanced, DNA and proteins are damaged and cellular transcription networks are activated.

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

open access: yesAdvanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

Functional Interplay Between Arabidopsis NADPH Oxidases and Heterotrimeric G Protein

open access: yesMolecular Plant-Microbe Interactions, 2013
The plant NADPH oxidases produce reactive oxygen species (ROS) in response to pathogens that have diverse functions in different cellular contexts. Distinct phenotypic outcomes may derive from the interaction of NADPH oxidase-dependent ROS with other ...

Kinetic characterization of selective peroxisome-proliferator-activated receptor gamma modulators in vitro [PDF]

open access: yes, 2012
Background: The ligand-activated transcription factor, peroxisome-proliferator-activated receptor gamma (PPARγ), has been shown to play an essential role in immunosuppression during sepsis.

Gallium‐Doped MXene Nanozymes Protect Liver Through Multi‐Death Pathway Blockade and Hepatocyte Regeneration

open access: yesAdvanced Science, EarlyView.
This study develops gallium‐doped V2C MXene nanozymes (Ga‐V2C) to treat acetaminophen‐induced liver injury through multi‐death pathway blockade and hepatocyte regeneration. Unlike conventional single‐target therapies like N‐acetylcysteine, Ga‐V2C nanozymes enable oxidative stress suppression, apoptosis, and ferroptosis inhibition, and enhanced ...

Reactive oxygen species generated in chloroplasts contribute to tobacco leaf infection by the necrotrophic fungus Botrytis cinerea [PDF]

open access: yes, 2017
Reactive oxygen species (ROS) play fundamental roles in plant responses to pathogen infection, including modulation of cell death processes and defense-related gene expression.

Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes

open access: yesAdvanced Science, EarlyView.
Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...

Mitochondrial regulation of NADPH oxidase in hindlimb unweighting rat cerebral arteries.

open access: yesPLoS ONE, 2014
Exposure to microgravity results in post-flight cardiovascular deconditioning and orthostatic intolerance in astronauts. Vascular oxidative stress injury and mitochondrial dysfunction have been indicated in this process.

Potential role of NADPH-oxidase in early steps of lead-induced oxidative burst in Vicia faba roots [PDF]

open access: yes, 2008
The mechanism of oxidative burst induced by lead in Vicia faba excised roots was investigated by luminol-dependent chemiluminescence. Results showed that lead triggered a rapid and dose-dependent increase in chemiluminescence production.

ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

open access: yesAdvanced Science, EarlyView.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.
