Findings for c-Myc promoter were nearly identical (Figure S3a–f), indicating that the processes of macrophage-mediated proliferation and endocrine resistance in breast cancer cells are associated with differential recruitment of transcription factors ERα and NF-κB, and of transcriptional coactivators, to promoters of genes that play key roles in cell cycle progression. This evidence concerns the gene NFKB1 and breast carcinoma.
