Abstract: Patterns of differential TF binding in open chromatin regions among TNBC cell lines derived from EA and AA women. A, Overabundance of known TF motifs within differentially open regions. Heat map of top 50 most variable TFs by cell line donor ancestry based on differential ATAC signal analysis. B, Volcano plot of predicted differences in TF binding scores by patient group using digital footprinting analysis with TOBIAS. Open chromatin regions defined by TF binding sites are significantly different between cell lines from AA and EA patients. A total of 79 TFs were differentially bound in AA versus EA TNBC lines (points in red indicate TFs with differential binding score > |0.225| and FDR<0.01). A differential binding score of greater than 0.225 indicates increased binding in EA. A differential binding score of less than −0.225 indicates increased binding in AA. C, Top-ranked 10 TFs with differential binding capacities in the two donor groups identified through digital footprinting analysis.
