SLC39A6 and cancer: Statistical analysis of Zn transporter expression indicated that similar to what was observed in breast tumor tissues, basal-like cancer cells also had significantly higher expression of MTs and SLC39A14 and lower expression of SLC39A6, SLC39A9, and SLC39A11 (fold-change >1.5; FDR, p < 0.05) (Table 1).
