Reactive oxygen species (ROS) levels were assessed by C11-BODIPY probe, oxidative stress indicators including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase were measured by kits, and Cytochrome C, Ferritin, mitochondrial transcription factor A (TFAM), glutathione peroxidase 4 (GPX4) and SLC7A5 expression were detected by Western blot
