Changing Perspectives from Oxidative Stress to Redox Signaling—Extracellular Redox Control in Translational Medicine

open access: yesAntioxidants, 2022
Extensive research has changed the understanding of oxidative stress that has been linked to every major disease. Today we distinguish oxidative eu- and distress, acknowledging that redox modifications are crucial for signal transduction in the form of ...

Plasmodium falciparum glyoxalase II: Theorell-Chance product inhibition patterns, rate-limiting substrate binding via Arg(257)/Lys(260), and unmasking of acid-base catalysis [PDF]

open access: yes, 2009
Glyoxalase II (GloII) is a ubiquitous thioester hydrolase catalyzing the last step of the glutathione-dependent conversion of 2-oxoaldehydes to 2-hydroxycarboxylic acids.

5-Methyltetrahydrofolate Attenuates Oxidative Stress and Improves Kidney Function in Acute Kidney Injury through Activation of Nrf2 and Antioxidant Defense

open access: yesAntioxidants, 2022
Oxidative stress is a major mediator of adverse outcomes in acute kidney injury (AKI). Deficiency of micronutrients, such as folate, is common in AKI. Our previous study reported that AKI impaired kidney reabsorption of folate and decreased plasma folate

Aging-Related Decline of Glutathione Peroxidase 3 and Risk of Cardiovascular Events in Patients With Atrial Fibrillation [PDF]

open access: yes, 2016
BACKGROUND: Experimental studies demonstrated that glutathione peroxidase 3 (GPx3), an antioxidant enzyme that catabolizes hydrogen peroxide, protects against thrombosis. Little is known about its role in cardiovascular disease. METHODS AND RESULTS:

Effect of a significant deficiency in some antioxidants on semen parameters in cases of male infertility in Diyala Province, Iraq [PDF]

open access: yesJournal of Research in Applied and Basic Medical Sciences, 2023
Background & Aims:  Scientific evidence indicates that oxidative stress (OS) is a major factor in the etiology of male infertility. OS occurs when there is an imbalance between reactive oxygen species (ROS) and protective antioxidants.

Metabolomic Analysis of Carbohydrate and Amino Acid Changes Induced by Hypoxia in Naked Mole-Rat Brain and Liver

open access: yesMetabolites, 2022
Hypoxia poses a major physiological challenge for mammals and has significant impacts on cellular and systemic metabolism. As with many other small rodents, naked mole-rats (NMRs; Heterocephalus glaber), who are among the most hypoxia-tolerant mammals ...

Glutathione and mitochondria [PDF]

open access: yesFrontiers in Pharmacology, 2014
Glutathione (GSH) is the main non-protein thiol in cells whose functions are dependent on the redox-active thiol of its cysteine moiety that serves as a cofactor for a number of antioxidant and detoxifying enzymes. While synthesized exclusively in the cytosol from its constituent amino acids, GSH is distributed in different compartments, including ...

Liposomes as Carriers for the Delivery of Efavirenz in Combination with Glutathione—An Approach to Combat Opportunistic Infections

open access: yesApplied Sciences, 2022
Human immunodeficiency virus (HIV)-infected individuals display an enhanced production of reactive oxygen species (ROS). This reduction of antioxidant capacity in host tissues has been related to the decrease in total levels of ROS scavengers such as ...

Glutathione synthesis [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 2013
Glutathione (GSH) is present in all mammalian tissues as the most abundant non-protein thiol that defends against oxidative stress. GSH is also a key determinant of redox signaling, vital in detoxification of xenobiotics, and regulates cell proliferation, apoptosis, immune function, and fibrogenesis.

Investigation of the thiol-disulfide system state of rats with encephalopathy caused by the effect of antituberculous drugs

open access: yesPatologìâ, 2019
Objective. To determine in an experimental study the nature of changes in the status of the thiol-disulfide system of rats with encephalopathy, due to the influence of complex of anti-tuberculosis drugs for the treatment of chemoresistant tuberculosis ...
