Using a well-defined list of human ZnT and ZIP proteins (23), we identified ten Zn proteins which are differentially expressed (FDR-adjusted P < 0.1) in MDA-MB-231 compared to other basal-like breast cancer cell lines (e.g., Her2, Luminal A and Luminal B) (Table 3). Here, ERBB2 is linked to breast carcinoma.
