IRF2BP2 and breast cancer: RNA-Seq analyses of the transcriptome from our 52 BC cell lines demonstrated that the Log2-based mRNA expression levels of MYC, EGFR, ASAP1, and CCT5 were higher in TNBC than non-TNBC cell lines (Supplementary Table 3), while similar high IRF2BP2 and low DRD1 were expressed in both cell types (Fig. 4a).
