This study selected Nrf2 and Nrf2 pathway-related genes to do a systematic analysis in pan-cancer, including ATF4, BACH1, CREBBP, CUL3, EIF2AK3, EP300, FOS, FOSL1, GSK3B, JUN, KEAP1, MAF, MAFF, MAFG, MAFK, MAPK1, MAPK3, MAPK7, MAPK8, MAPK9, NRF2, PIK3CA, PRRT2, and RIT1. This evidence concerns the gene KEAP1 and cancer.
