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 ). WebConditional deficiency of GPX4 in the kidney has been shown to cause ferroptotic death of tubular epithelial cells leading to acute kidney injury, which was ameliorated by liproxstatin-1, a spiroquinoxalinamine derivative. 59 GPX4 activity relies on GSH levels, and GSH depletion leads to the loss of function of GPX4. 78 The key determinant of ...
