Selenoprotein GPX4 (glutathione peroxidase 4), originally known as PHGPX (phospholipid hydroperoxide glutathione peroxidase), is the main oxidoreductase in use of a reducing agent scavenging lipid peroxidation products. There are three isoforms: cytosolic (cGPX4), mitochondrial (mGPX4), and nuclear (nGPX4), with distinct spatiotemporal expression patterns during embryonic development adult life. In addition to inducing phenotype ferroptosis, loss can some cells trigger apoptosis, necroptosis, pyroptosis, or parthanatos, which mediates accelerates developmental defects, tissue damage, sterile inflammation. The interaction autophagic degradation pathway further modulates cell fate response oxidative stress.

Abstract Regulated cell death (RCD) is a regulable that involves well-organized signaling cascades and molecular mechanisms. RCD implicated in fundamental processes such as organ production tissue remodeling, removing superfluous structures or cells, regulating numbers. Previous studies have not been able to reveal the complete mechanisms, novel methods of are constantly being proposed. Two metal ions, iron (Fe) copper (Cu) essential factors leading RCDs only induce ferroptosis cuproptosis, respectively but also lead impairment eventually diverse death. This review summarizes direct indirect mechanisms by which Fe Cu impede growth various forms mediated these two metals. Moreover, we aimed delineate interrelationships between with distinct pathways shedding light on complex intricate govern cellular survival Finally, prospects outlined this suggest approach for investigating death, may involve integrating current therapeutic strategies offer promising solution overcome drug resistance certain diseases.
