Ferroptosis is an iron-dependent novel type of programmed cell death. The main features of ferroptosis include lipid reactive oxygen accumulation, iron accumulation and lipid peroxidation. The main mechanisms and signal pathways of ferroptosis are complex and closely related to cystine/glutamate antiporter system, glutathione peroxidase 4, ferroptosis suppressor protein 1, and dihydroorotate dehydrogenase. This review summarizes the current regulatory mechanisms of ferroptosis and discusses the research progress of ferroptosis in tumors, non-alcoholic fatty liver disease, Parkinson's disease, and congestive heart failure.
