Lipid Metabolism in Ferroptosis

Lipid metabolism is a complex biochemical process that participates in the regulation of cell survival and death. Ferroptosis is a form of iron-dependent regulated cell death driven by abnormal lipid metabolism, leading to lipid peroxidation and subsequent plasma membrane rupture. A variety of antioxidant systems and membrane repair pathways can diminish oxidative damage, enabling survival and growth in response to ferroptotic signals. Such impairment of ferroptosis machinery is implicated in various pathological conditions and diseases, especially cancer and tissue damage. It is discussed here how lipid metabolism pathways, including lipid synthesis, degradation, storage, transformation, and utilization, modulate ferroptosis sensitivity or tolerance in different models, especially cancer.

Automated summary

Lipid metabolism plays a crucial role in regulating cell survival and death. Abnormal lipid metabolism can lead to ferroptosis, an iron-dependent regulated cell death. Various antioxidant systems and membrane repair pathways help mitigate oxidative damage and support cell survival, especially in pathological conditions like cancer. Impairment of the ferroptosis machinery is associated with the development of diseases such as cancer and tissue damage.
