A) Unbiased, pan-cancer analysis of mutations that are significantly related (co-occurring or mutual exclusive) with KEAP1 and NRF2 using the SELECT algorithm (see text and methods for details); B) Oncoprint showing mutual exclusive relation between NRF2/ KEAP1 and EGFR mutations in human cancers; C) Nuclear extracts from HepG2 cells treated with NRF2 inducer DLS (1 μM, 24 hours), EGF (10 ng/mL, 24 hours), TGFα (1 nM, 24 hours) or DMSO and probed with antibodies against NRF2 and lamin B; D) Nuclear (upper panel) and cytoplasmic extracts (lower panel) from H3255 (EGFRL858R) cells transduced with EGFR-specific shRNA or control and immunoblotted with indicated antibodies; E) Viability of isogenic H3255 cells transduced with sgRNAs targeting KEAP1 or LacZ (control) and treated with erlotinib; error bars represent SD from 3 replicates; F) Lysates from paired PC9 cells transduced with indicated sgRNA-Cas9 constructs and treated with DMSO or erlotinib (10 nM, 6 hours) probed with the indicated antibodies.
