Microarray analysis reveals differential expression of SLC30A, SLC39A, and MT genes in breast cancer subtypes. Subtype dependent differential expression of SLC30A, SLC39A, and MT genes in a breast tumors and b cell lines were identified using ANOVA and the heat map representing differential expression of significant genes (FDR <0.05) is shown. Breast tumor classification is indicated by the color bar across the top as Basal (red), ER⁺-High Grade (ER HG, blue), ER⁺-Low Grade (ER LG, green), HER (purple) and cell lines classified as Luminal (blue) and Basal (red). The classifications were used as ANOVA factors and the mean log2 expression value was shifted to zero to generate the heatmap
