In addition, we found a significant positive correlation between SDCBP and BACH1 expression (P < 0.0001; Pearson correlation coefficient = 0.5772) in 78 tumor tissue samples from patients with TNBC (Fig. 1A,B), and this Pearson correlation coefficient was more reliable than that observed in SDCBP and BACH1 mRNA expression (Fig. EV1A,B), suggesting a strong positive correlation between SDCBP and BACH1 protein expression in TNBC tissues. This evidence concerns the gene BACH1 and neoplasm.
