In addition, diquat exposure induced cardiolipin peroxidation in the liver of Wt mice; the levels of cardiolipin peroxidation were reduced in Tg (GPX4 (+/0)) mice but elevated in Gpx4+/- mice.

Glutathione peroxidase 4 (Gpx4) is an antioxidant defense enzyme found in mitochondria as well as other subcellular organelles that directly detoxifies membrane lipid hydroperoxides.
To determine if Gpx4 protects ATP production in vivo, we compared mitochondrial ATP production between wild-type mice and Gpx4 transgenic mice using a diquat model.
