Proteomic and metabolomic analysis of ageing beef exudate to determine that iron metabolism enhances muscle protein and lipid oxidation

open access: yesFood Chemistry: X, 2023
The study aimed to assess differences in proteomic and metabolite profiles in ageing (1, 2, 4, and 6 days at 4 °C) beef exudates and determine their relationship with beef muscle iron metabolism and oxidation.

Eukaryotic Initiation Factor 4A-3: A Review of Its Physiological Role and Involvement in Oncogenesis

open access: yesFrontiers in Oncology, 2021
EIF4A3, a member of the DEAD-box protein family, is a nuclear matrix protein and a core component of the exon junction complex (EJC). Under physiological conditions, EIF4A3 participates in post-transcriptional gene regulation by promoting EJC control of ...

Reactivity of mitochondrial peroxiredoxins with biological hydroperoxides

open access: yesRedox Biochemistry and Chemistry, 2023
Mitochondria are main sources of biological hydroperoxides, including hydrogen peroxide, peroxynitrite and various organic hydroperoxides. Most of these species are involved in the regulation of cellular functions when formed at low, physiological levels.

Phospholipid hydroperoxide glutathione peroxidase activity of human glutathione transferases [PDF]

open access: yesBiochemical Journal, 1998
Human glutathione transferases (GSTs) from Alpha (A), Mu (M) and Theta (T) classes exhibited glutathione peroxidase activity towards phospholipid hydroperoxide. The specific activities are in the order: GST A1-1 > GST T1-1 > GST M1-1 > GST A2-2 > GST A4-4.

Metabolism of hydroperoxy-phospholipids in human hepatoma HepG2 cells

open access: yesJournal of Lipid Research, 1996
Two enzymatic mechanisms have been proposed for the metabolism of hydroperoxy-phospholipids: i) the combined action of phospholipase A2 and glutathione peroxidase, and/or ii) direct enzymatic reduction.

Expression of a catalytically inactive mutant form of glutathione peroxidase 4 (Gpx4) confers a dominant-negative effect in male fertility. [PDF]

open access: yes, 2015
The selenoenzyme Gpx4 is essential for early embryogenesis and cell viability for its unique function to prevent phospholipid oxidation. Recently, the cytosolic form of Gpx4 was identified as an upstream regulator of a novel form of non-apoptotic cell ...

Saccharomyces cerevisiae Expresses Three Phospholipid Hydroperoxide Glutathione Peroxidases [PDF]

open access: yesJournal of Biological Chemistry, 2001
The GPX1, GPX2, and GPX3 genes of Saccharomyces cerevisiae have been reported previously to encode glutathione peroxidases (GPxs). We re-examined the sequence alignments of these proteins with GPxs from higher eukaryotes. Sequence identities, particularly with phospholipid hydroperoxide glutathione peroxidases (PHGPxs), were enhanced markedly by ...

Exogenous salicylic acid enhances wheat drought tolerance by influence on the expression of genes related to ascorbate-glutathione cycle

open access: yesBiologia Plantarum, 2013
Treatment with 0.5 mM salicylic acid (SA) significantly alleviated growth inhibition induced by drought in wheat seedlings, manifested by less decreassed fresh mass, dry mass, plant height, root length, and less increased lipid peroxidation.

Reduction of thymine hydroperoxide by phospholipid hydroperoxide glutathione peroxidase and glutathione transferases [PDF]

open access: yesFEBS Letters, 1997
Thymine hydroperoxide (5‐hydroperoxymethyluracil), a model compound representing products of oxidative damage to DNA, is a substrate for glutathione peroxidase and some isoforms of glutathione transferase. In this paper, we show that selenium‐dependent human phospholipid hydroperoxide glutathione peroxidase (Se‐PHGPx) exhibits about four orders of ...

Selenoprotein gene nomenclature [PDF]

open access: yes, 2016
The human genome contains 25 genes coding for selenocysteine-containing proteins (selenoproteins). These proteins are involved in a variety of functions, most notably redox homeostasis.
