Microglial glutathione and glutamate: regulation mechanisms [PDF]

open access: yes, 2009
Microglia, the immune cells of the central nervous system (CNS), are important in the protection of the CNS, but may be implicated in the pathogenesis of neuroinflammatory disease.

Coordinate induction of glutathione biosynthesis and glutathione-metabolizing enzymes is correlated with salt tolerance in tomato [PDF]

open access: yes, 2003
The acclimation of reduced glutathione (GSH) biosynthesis and GSH-utilizing enzymes to salt stress was studied in two tomato species that differ in stress tolerance. Salt increased GSH content and GSH:GSSG (oxidized glutathione) ratio in oxidative stress-

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Arginine-Mediated Liver Immune Regulation and Antioxidant Defense in Largemouth Bass (Micropterus salmoides): Multi-Omics Insights into Metabolic Remodeling During Nocardia seriolae Infection

open access: yesAntioxidants
The liver of fish is an essential metabolic organ that also serves an immune regulatory role. In this study, we constructed a model of largemouth bass (Micropterus salmoides) infected with Nocardia seriolae by injection to explore the immune and ...

Glutathione and Glutathione Delivery Compounds

open access: yes, 1996
Deficiency of GSH (BSO model) demonstrates the need for cellular protection from endogenous ROS. The pathology of various diseases is often associated with ROS and oxidative stress. The several methods for modulating cellular GSH levels presented in this chapter offer selective tools to study mechanisms and offer potential therapy of human diseases ...

Oxygen Depletion and the Role of Cellular Antioxidants in FLASH Radiotherapy: Mechanistic Insights from Monte Carlo Radiation-Chemical Modeling

open access: yesAntioxidants
FLASH radiotherapy is a novel irradiation modality that employs ultra-high mean dose rates exceeding 40–150 Gy/s, far surpassing the typical ~0.03 Gy/s used in conventional radiotherapy.

Glutathione treatment protects the rat liver against injury after warm ischemia and Kupffer cell activation [PDF]

open access: yes, 2002
Background/Aim: The generation of reactive oxygen species by activated Kupffer cells (KC) may contribute to reperfusion injury of the liver during liver transplantation or resection.

Coordination‐Modulated Catalytic Pathways at Carbon Dots‐Supported Single‐Atom Sites Revealed by Thiol Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Carbon dots‐supported single‐atom catalysts provide a model platform for uncovering how coordination interactions regulate catalytic reactivity. Thiol binding at Ru‒N4 centers reshapes the reaction energy landscape of H2O2 activation, dynamically modulating ROS‐generation pathways through electronic‐structure perturbation.

Reductive stress in mitochondria isolated from the carotid body of type 1 diabetic male Wistar rats

open access: yesPhysiological Reports
The carotid body (CB) senses changes in arterial O2 partial pressure (pO2) and glucose levels; therefore, it is key for the detection of hypoxia and hypoglycemia. The CB has been suggested to detect pO2 through an increase in reactive oxygen species (ROS)
