a NRF-1 ChIP-seq signal in NRF-1 uniquely bound sites identified by overlapping MCF-7 and ADR NRF-1 peaks. Upper panel: Venn diagram showing the overlap of NRF-1 peaks in MCF-7 and ADR cells. The percentage of peaks annotated to promoter regions is indicated. Lower panel: Heat map representation of NRF-1 signal enrichment (red, low; blue, high) at NRF-1 uniquely bound sites. The enrichment levels were profiled ±3 kb from the peak center. b Heat map representation of COGC-seq signal enrichment (red, low; blue, high) at NRF-1 uniquely bound sites. The enrichment levels were profiled ±3 kb from the peak center. c Average enrichment profiles of published H3K27ac, H3K4me3 (GSE97481), H3K27me3 (GSE96363) and H3K4me1 (GSE86714) ChIP-seq reads at NRF-1 uniquely bound sites. d The box plots showing the mRNA expression changes (RNA-seq FPKM) of NRF1-binding genes associated with MCF-7- and ADR-biased peaks. The box plots show the medians (black lines), 25th and 75th percentiles (boundaries), and minimum/maximum values (whiskers). The p value (0.0000006, two-sided unpaired Student’s t-test, calculated between multiple genes in each group) is indicated. n = 2 biologically independent RNA-seq replicates. Source Data are provided as a Source Data file. e Heat map representation of WT-NRF-1 and AA-NRF-1 signal enrichment (red, low; blue, high) at NRF-1 binding sites in MCF-7 and ADR cells. The enrichment levels were profiled ±3 kb from the peak center.
