FSP1, a novel KEAP1/NRF2 target gene regulating ferroptosis and radioresistance in lung cancers.

In the study of "A targetable CoQ-FSP1 axis drives ferroptosis- and radiation-resistance in KEAP1 inactive lung cancers" which was published earlier in Nature Communications, the authors have identified a novel KEAP1/NRF2 target gene, FSP1, and demonstrated that FSP1 plays an essential role in NRF2-mediated ferroptosis resistance and radioresistance in KEAP1-deficient lung cancer cells. Currently, many NRF2 target genes have been found to participate in the regulation of ferroptosis, and exactly which one plays a dominant role seems unclear. This study proposes that FSP1 is the key effector in NRF2-mediated ferroptosis resistance and radioresistance in KEAP-deficient lung cancer cells, as we discussed in the manuscript.
