The ferroptosis‐related transcription factors NFE2L2/NRF2, TP53, BACH1, SP1, ATF3, ATF4, YAP1, TAZ, TFEB, TFAP2C, HIF1A, EPAS1/HIF2A, JUN, HIC1, and HNF4A were individually knocked out in cancer cells, after which Parkin mRNA levels were analyzed (Figure 3E). The gene discussed is ATF4; the disease is cancer.
