Ferroptosis is a non-apoptotic form of regulated cell death.It differs from other types of controlled cell death, like apoptosis and necroptosis. Large-scale lipid peroxidation, which is a hallmark of ferroptosis, can be prevented by lipophilic antioxidants or iron chelators. Ferroptosis inducers can be categorized into two groups based on their mechanisms: (1) inhibitors of cystine import via system xc (such as Erastin), which lead to the depletion of glutathione (GSH), and (2) covalent inhibitors of glutathione peroxidase 4 (GPX4), such as (1S, 3R)-RSL3. Both compound classes ultimately lead to a loss of GPX4 activity, which is followed by increased levels of lipid reactive oxygen species (ROS) and eventual cell death. GPX4 reduces lipid hydroperoxides using GSH as a co-substrate.
Iron and ROS are required for the regulated cell death (RCD) process known as ferroptosis. Misregulated ferroptosis has been linked to a number of physiological and pathological processes, such as T-cell immunity, drug-induced hepatotoxicity, hepatic and heart ischemia/reperfusion injury, neurotoxicity, and the death of cancer cells.
