Selenoproteins in mammalian spermatogenesis:role of the nuclear GPx4 [PDF]
, 2011 The selenoprotein Phospholipid Hydroperoxide Glutathione Peroxidase (PHGPx/GPx4) is an enzyme unique among the various GPxs, because it is able to use protein thiols, beside glutathione, The GPx4 gene encodes for three isoforms having different ...

GPX4 in cell death, autophagy, and disease
Autophagy, 2023 Selenoprotein GPX4 (glutathione peroxidase 4), originally known as PHGPX (phospholipid hydroperoxide glutathione peroxidase), is the main oxidoreductase in the use of glutathione as a reducing agent in scavenging lipid peroxidation products. There are three GPX4 isoforms: cytosolic (cGPX4), mitochondrial (mGPX4), and nuclear (nGPX4), with distinct ...

Different genes interact with particulate matter and tobacco smoke exposure in affecting lung function decline in the general population [PDF]
, 2012 BACKGROUND: Oxidative stress related genes modify the effects of ambient air pollution or tobacco smoking on lung function decline. The impact of interactions might be substantial, but previous studies mostly focused on main effects of single genes ...

Drug-tolerant persister cancer cells are vulnerable to GPX4 inhibition. [PDF]
, 2017 Acquired drug resistance prevents cancer therapies from achieving stable and complete responses. Emerging evidence implicates a key role for non-mutational drug resistance mechanisms underlying the survival of residual cancer 'persister' cells.

A mTORC1-mediated cyst(e)ine sensing mechanism governing GPX4 synthesis and ferroptosis
Molecular & Cellular Oncology, 2021 Ferroptosis is a cell death mechanism triggered by lipid peroxidation. Our recent study linked cyst(e)ine availability with glutathione peroxidase 4 (GPX4) protein synthesis and ferroptosis mitigation via a Rag-mechanistic target of rapamycin complex 1 ...

The CoQ oxidoreductase FSP1 acts parallel to GPX4 to inhibit ferroptosis. [PDF]
, 2019 Ferroptosis is a form of regulated cell death that is caused by the iron-dependent peroxidation of lipids1,2. The glutathione-dependent lipid hydroperoxidase glutathione peroxidase 4 (GPX4) prevents ferroptosis by converting lipid hydroperoxides into non-

Nature Chemical Biology, 2020 Ferroptosis induced by GPX4 inhibition offers promise for killing drug-resistant cancer cells, yet current GPX4 inhibitors lack selectivity. The discovery of masked nitrile oxide electrophiles as selective prodrug inhibitors of GPX4 points to an attractive path for chemically inducing ferroptosis.
