WebFeb 15, 2024 · Since its discovery in 2012, many research studies have been published focusing on the mechanisms of ferroptosis, its induction in tumor cells, which is carried out by many chemical compounds, or its prevention in various human disorders, such as in neurodegeneration or ischemia reperfusion injury. WebJul 7, 2024 · Inhibiting the mitochondrial electron transport chain also attenuates ferroptosis induced by cys starvation, as does depletion of mitochondria (Gao et al., 2024; Figure 3). The role of the electron transport chain may be due to the leakage of electrons that produce superoxide and H 2 O 2 , which can then react with Fe(II) to drive Fenton ...
