Abstract: Ferroptosis is an iron-dependent programmed cell death mode that is distinct from other
cell death modes, and radiation is able to stimulate cellular oxidative stress and induce the production
of large amounts of reactive oxygen radicals, which in turn leads to the accumulation of lipid
peroxide and the onset of ferroptosis. In this review, from the perspective of the role of ferroptosis
in generating a radiation response following cellular irradiation, the relationship between ferroptosis
induced by ionizing radiation stress and the response to ionizing radiation is reviewed, including
the roles of MAPK and Nrf2 signaling pathways in ferroptosis, resulting from the oxidative
stress response to ionizing radiation, the metabolic regulatory role of the p53 gene in ferroptosis,
and regulatory modes of action of iron metabolism and iron metabolism-related regulatory proteins
in promoting and inhibiting ferroptosis. It provides some ideas for the follow-up research to
explore the specific mechanism and regulatory network of ferroptosis in response to ionizing radiation.
