(A) The relative expression of ZIP14 normalized to ACTB in ZIP14 knockdown (KD) cells expressing two different shRNAs compared to scrambled control shRNA. (B) Cytosolic Zn2+ concentration in ZIP14 KD cells compared to control cells at 6 days post hormone treatment. Each dot represents a single cell and black line represents the mean value of each group. Error bar represents standard deviation. **, p< 0.0001, one-way ANOVA test with Post Hoc Tukey HSD (n > 9). (C-D) ZIP14 knockdown depressed the mRNA expression of WAP (D) but had no effect in the CSN2 mRNA level (C) in D day6 cells. Relative mRNA level in (A, C, D) was determined using RT-qPCR and mean values are represented by bar plots with each dot representing a biological replicate. *, P < 0.05; **, p < 0.001, unpaired student’s t-test (n=4).
