Glutathione peroxidase 4‐dependent glutathione high‐consumption drives acquired platinum chemoresistance in lung cancer‐derived brain metastasis

open access: yesClinical and Translational Medicine, 2021
Background Platinum‐based chemotherapy is effective in inducing shrinkage of primary lung cancer lesions; however, it shows finite therapeutic efficacy in patients suffering from brain metastasis (BM).

Long chain lipid hydroperoxides increase the glutathione redox potential through glutathione peroxidase 4 [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 2019
Peroxidation of PUFAs by a variety of endogenous and xenobiotic electrophiles is a recognized pathophysiological process that can lead to adverse health effects. Although secondary products generated from peroxidized PUFAs have been relatively well studied, the role of primary lipid hydroperoxides in mediating early intracellular oxidative events is ...

Glutathione peroxidase 4: a new player in neurodegeneration? [PDF]

open access: yesMolecular Psychiatry, 2016
Glutathione peroxidase 4 (GPx4) is an antioxidant enzyme reported as an inhibitor of ferroptosis, a recently discovered non-apoptotic form of cell death. This pathway was initially described in cancer cells and has since been identified in hippocampal and renal cells.

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 ...

Anti-cancer effect of thiacremonone through down regulation of peroxiredoxin 6. [PDF]

open access: yesPLoS ONE, 2014
Thiacremonone (2, 4-dihydroxy-2, 5-dimethyl-thiophene-3-one) is an antioxidant substance as a novel sulfur compound generated from High-Temperature-High-Pressure-treated garlic.

Induction mechanism of ferroptosis: A novel therapeutic target in lung disease

open access: yesFrontiers in Pharmacology, 2022
Ferroptosis is a newly discovered form of non-apoptotic regulatory cell death driven by iron-dependent lipid peroxidation. Ferroptosis significantly differs from other forms of cell death in terms of biochemistry, genetics, and morphology.

Ferroptosis in the pathogenesis of brain tumors [PDF]

open access: yesКлиническая практика, 2023
The field of research on ferroptosis has seen an explosive growth in the past few years since the term was coined in 2012. This review highlights the current state of knowledge on the developmental mechanism of this unique mode of cell death, induced by ...

Paradoxical roles of antioxidant enzymes:Basic mechanisms and health implications [PDF]

open access: yes, 2015
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated from aerobic metabolism, as a result of accidental electron leakage as well as regulated enzymatic processes.

Induction of Glutathione Peroxidase 4 Expression during Enterocytic Cell Differentiation [PDF]

open access: yesJournal of Biological Chemistry, 2011
Glutathione peroxidase 4 (GPx4), an abundant selenoenzyme, is ubiquitously expressed in a tissue-, cell- and differentiation-dependent manner, and it is localized in cytoplasmic, mitochondrial, and nuclear cellular compartments. Here, we report cytoplasmic and nuclear localization of GPx4 in Caco-2 intestinal epithelial cells.
