Ferroptosis is an oxidative form of cell death whose biochemical regulation remains incompletely understood. Cap’n’collar (CNC) transcription factors including nuclear factor erythroid-2–related factor 1 (NFE2L1/NRF1) and NFE2L2/NRF2 can both regulate oxidative stress pathways but are each regulated in a distinct manner, and whether these two transcription factors can regulate ferroptosis independent of one another is unclear. We find that NFE2L1 can promote ferroptosis resistance, independent of NFE2L2, by maintaining the expression of glutathione peroxidase 4 (GPX4), a key protein that prevents lethal lipid peroxidation. NFE2L2 can also promote ferroptosis resistance but does so through a distinct mechanism that appears independent of GPX4 protein expression. These results suggest that NFE2L1 and NFE2L2 independently regulate ferroptosis. Ferroptosis is an oxidative form of nonapoptotic cell death whose transcriptional regulation is poorly understood. Cap’n’collar (CNC) transcription factors including nuclear factor erythroid-2–related factor 1 (NFE2L1/NRF1) and NFE2L2 (NRF2) are important regulators of oxidative stress responses. NFE2L1 abundance and function are regulated posttranslationally by N-glycosylation. Functional maturation of NFE2L1 requires deglycosylation by cytosolic peptide:N-glycanase 1 (NGLY1). We find that NGLY1 and NFE2L1 work in a common pathway to enhance ferroptosis resistance, independent of NFE2L2, by promoting expression of the key antiferroptotic enzyme glutathione peroxidase 4 (GPX4). Enhanced ferroptosis sensitivity in NFE2L1-knockout cells can be reverted by expression of an NFE2L1 mutant containing eight asparagine-to-aspartate protein sequence substitutions, which mimic NGLY1-catalyzed protein sequence editing. These results suggest that ferroptosis sensitivity may be regulated by NGLY1-catalyzed NFE2L1 deglycosylation. These results highlight a role for the disease-associated NGLY1/NFE2L1 pathway in ferroptosis regulation.
