Ferrostatin-1 protects HT-22 cells from oxidative toxicity.

ABSTRACT: Ferroptosis is a type of programmed cell death dependent on iron. It is different from other forms of cell death such as apoptosis, classic necrosis and autophagy. Ferroptosis is involved in many neurodegenerative diseases. The role of ferroptosis in glutamate-induced neuronal toxicity is not fully understood. To test its toxicity, glutamate (1.25-20 mM) was applied to HT-22 cells for 12 to 48 hours. The optimal experimental conditions occurred at 12 hours after incubation with 5 mM glutamate. Cells were cultured with 3-12 μM ferrostatin-1, an inhibitor of ferroptosis, for 12 hours before exposure to glutamate. The cell viability was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Autophagy was determined by monodansylcadaverine staining and apoptosis by cas
