Primary structure of the nuclear forms of phospholipid hydroperoxide glutathione peroxidase (PHGPx) in rat spermatozoa [PDF]

open access: yes, 2004
Phospholipid hydroperoxide glutathione peroxidase is a monomeric Se-peroxidase highly expressed in mammalian male germ cells. Its nuclear form, sperm nuclei glutathione peroxidase (snGPx), has been originally identified in maturating spermatozoa as a ...

Effects of trichotecene mycotoxins on gene expression and activity of glutathione redox system in common carp (Cyprinus carpio L.)

open access: yesFrontiers in Marine Science, 2015
The purpose of present study was to evaluate the short- and long-term effects of T-2 toxin and deoxynivalenol (DON) in common carp. Short-term effect was evaluated using single oral doses of DON or T-2 toxin of 0.25, 0.50 or 3.00 mg/kg b.w ...

Crystal and solution structural studies of mouse phospholipid hydroperoxide glutathione peroxidase 4. [PDF]

open access: yes, 2016
The mammalian glutathione peroxidase (GPx) family is a key component of the cellular antioxidative defence system. Within this family, GPx4 has unique features as it accepts a large class of hydroperoxy lipid substrates and has a plethora of biological ...

Tolerance to Stress Combination in Tomato Plants: New Insights in the Protective Role of Melatonin

open access: yesMolecules, 2018
Abiotic stresses such as drought, heat or salinity are major causes of yield loss worldwide. Recent studies have revealed that the acclimation of plants to a combination of different environmental stresses is unique and therefore cannot be directly ...

Human umbilical cord mesenchymal stem cells derived exosome shuttling mir-129-5p attenuates inflammatory bowel disease by inhibiting ferroptosis

open access: yesJournal of Nanobiotechnology, 2023
Background Ferroptosis, a unique form of non-apoptotic cell death, is dependent on iron and lipoperoxidation, and has been shown to be associated with the pathogenesis of inflammatory bowel disease (IBD).

Lethal damage to endothelial cells by oxidized low density lipoprotein: role of selenoperoxidases in cytoprotection against lipid hydroperoxide- and iron-mediated reactions.

open access: yesJournal of Lipid Research, 1993
Oxidized low density lipoprotein (LDLox) is believed to be an important contributor to endothelial cytodamage and atherogenesis. The purpose of this study was to examine the role of glutathione (GSH) and GSH-dependent selenoperoxidases in cytoprotection ...

Structure and Functions of Phospholipid Hydroperoxide Glutathione Peroxidase

open access: yesJournal of Japan Oil Chemists' Society, 1999
Phospholipid hydroperoxide glutathione peroxidase is the only known intracellular antioxidant enzyme directly capable of reduing peroxidized phospholipids and cholesterol in membranes. PHGPx is a member of the selenoprotein family that contain the unique amino acid, selenocysteine, the active site for peroxidase activity.

Native specific activity of glutathione peroxidase (GPx-1), phospholipid hydroperoxide glutathione peroxidase (PHGPx) and glutathione reductase (GR) does not differ between normo- and hypomotyle human sperm samples [PDF]

open access: yes, 2004
Glutathione-dependent selenoenzymes in human spermatozoa are responsible for a generalized protection against reactive oxygen species (ROS) as well as some other metabolic and structural regulation during spermiogenesis and sperm cell maturation ...
