Focusing on the ZEB1 ChIP‐seq data, peaks were found at the promoter or enhancer regions of the identified genes, including IL6, IL8, and CSF2, in MDA‐231‐D and Hs578T cells, but not in MCF7 cells (Fig. 2D), suggesting that ZEB1 binds and regulates the expression of inflammatory response genes in basal‐type breast cancer cells. This evidence concerns the gene CXCL8 and breast cancer.
