WebMay 7, 2024 · Gpx4 is a unique gene that encodes cytosolic, mitochondrial, and nucleolar isoforms ( 14 ). Of note, the active site of GPx4 contains the rare amino acid selenocysteine (Sec), which is encoded by the UGA codon ( 15 ). Each form of GPx4 plays protective roles within each organelle, and their dysregulation is associated with disease ( 12, 16 – 21 ).
WebAug 31, 2024 · In 4T1 cells with medium GSH level, it depleted intracellular GSH and inactivated GSH peroxidase 4 (GPX4) and thus induced efficient ferroptosis. While in B16 cells with high GSH level, it exhausted GSH and triggered indirect increase of intracellular ROS and activation of Caspase 3 and gasdermin E, resulting in severe pyroptosis.
