Figure 1 Identification of ARF as a Component of the NRF2 Protein Complexes (A) Coomassie blue staining of affinity-purified protein complexes from nuclear extracts of a Flag-HA-NRF2/H1299 stable cell line (lane 2) and the parental H1299 cell line (lane 1). Specific NRF2-interacting protein bands were analyzed by MS. (B) Human 293 cells were co-transfected with expression vectors encoding NRF2-V5 and/or Flag-ARF, as indicated. Lysates were immunoprecipitated with FLAG/M2 beads, and the fractionated proteins were immunoblotted with antibody specific to the V5 (for NRF2; upper panel) or the Flag (for ARF; lower panel) epitope. (C) Co-immunoprecipitation of ARF with NRF2 from H1299 cells. Whole-cell extracts (lane 1) or immunoprecipitates generated with the NRF2 antibody (lane 3) or a control IgG (lane 2) were immunoblotted with anti-ARF (lower) or anti-NRF2 (upper) antibody. (D) Co-immunoprecipitation of NRF2 with ARF from H1299 cells. Whole-cell extracts (lane 1) and immunoprecipitates generated with the ARF antibody (lane 3) or a control IgG (lane 2) were immunoblotted with anti-ARF (upper) or anti-NRF2 (lower) antibody. (E) Western blot analysis of an in vitro GST pull-down assays of highly purified FH-NRF2 protein incubated with GST-ARF (lane 3) or GST alone (lane 2). (F) Western blot analysis of an in vitro GST pull-down assays of highly purified FH-NRF2 protein incubated with GST-ARF (1–64) (lane 3), GST-ARF (65–132) (lane 4), or GST alone (lane 2). (G) H1299 cells were transfected with the SLC7A11-Luc reporter construct together with expression vectors encoding NRF2 and differing amounts of ARF. Error bars, SD from three technical replicates. (H) H1299 cells were transfected with the SLC7A11-Luc reporter construct together with expression vectors encoding NRF2 and full-length HA-ARF, HA-ARF (1–64), or HA-ARF (65–132). Error bars, SD from three technical replicates. See also Figure S1. Molecular Cell 2017 68, 224-232.e4DOI: (10.1016/j.molcel.2017.09.009) Copyright © 2017 Elsevier Inc. Terms and Conditions

Figure 2 ARF Regulates the Transcriptional Activity of NRF2 and Promotes Ferroptosis (A) U2OS cells were co-transfected with expression vectors encoding FH-NRF2 and either full-length ARF or ARFΔ14, which lacks amino acids 1–14. Lysates were immunoprecipitated with FLAG-M2 beads, and the fractionated proteins were immunoblotted with HA-specific antibody (to detect FH-NRF2; upper panel) or ARF-specific antibody (lower panel). (B) H1299 cells were transfected with the SLC7A11-Luc reporter construct, together with expression vectors encoding NRF2 and full-length ARF or ARFΔ14. Error bars, SD from three technical replicates. (C) Extracts of ARF-inducible SaoS2 cells treated with doxycycline were immunoblotted with antibodies specific for NRF2, SLC7A11, ARF, and Actin. (D) Extracts of SaoS2 cells treated with an ARF-specific RNAi (lane 2) or a control RNAi (lane 1) were immunoblotted with antibodies specific for NRF2, SLC7A11, ARF, and Actin. (E) Extracts of ARF-inducible H1299 cells treated with doxycycline as indicated were immunoblotted with antibodies specific for NRF2, SLC7A11, ARF, and Actin. (F) Representative phase-contrast images of ferroptotic cell death induced by ROS (TBH treatment) in ARF-inducible H1299 cells treated with or without doxycycline and/or Ferrostatin-1 (Ferr-1) as indicated. (G) Quantification of ROS-induced cell death from (F) (error bars, SD from three technical replicates). (H) The percent cell death induced by ROS was determined for H1299 cells transfected with an empty expression vector or with expression vectors encoding ARF alone or ARF and NRF2 together (error bars, SD from three technical replicates).

Figure 3 ARF Can Induce Both p53-Dependent and p53-Independent Ferroptosis (A) ARF-inducible U2OS cells were treated with control RNAi (lane 1), p53 RNAi (lane 2), control RNAi + IPTG (lane 3), or p53 RNAi + IPTG (lane 4) as indicated, and cell extracts were immunoblotted with antibodies specific for NRF2, SLC7A11, p53, p21, ARF, and Actin. (B) Representative phase-contrast images of ARF-inducible U2OS cells treated with ROS and IPTG (to induce ARF expression) and/or Ferrostatin-1 (Ferr-1), as indicated. (C) Quantification of ROS-induced cell death of the cells shown in (B) (error bars, SD from three technical replicates). (D) Extracts of p53fl/fl and ARFfl/fl /p53fl/fl MEFs treated with either the Ad-Cre or the control Ad-GFP virus were immunoblotted with antibodies specific for p53 and ARF.

Quantification of ferroptotic cell death in p53fl/fl and ARFfl/fl /p53fl/fl MEFs treated with the Ad-Cre virus with or without Erastin as indicated (error bars, SD from three technical replicates). (F) 293 cells were transfected with expression vectors encoding Flag-NRF2, CBP-HA, and/or ARF/ARFΔ14 as indicated. Lysates were immunoprecipitated with FLAG-M2 beads, and the fractionated proteins were immunoblotted with the acetylated specific antibody to acetylated NRF2 (upper), the Flag antibody (for Flag-NRF2; middle). ARF or ARFΔ14 in crude lysates was analyzed by western blotting with anti-ARF antibody (lower). (G) ChIP-qPCR analysis of NRF2 binding on the endogenous SLC7A11 promoter. H1299 cells were transfected with expression vectors encoding FH-NRF2 and either full-length ARF or ARFΔ14, which lacks amino acids 1–14. Error bars, SD from three technical replicates.
