Specifically, SLC2A1, SLC2A6, SLC2A10, and SLC2A13 were significantly overexpressed, whereas SLC2A3, SLC2A4, SLC2A9, SLC2A11, and SLC2A12 had downregulated expressions in breast tumors compared with those in normal breast epithelium (Figure 1D). This evidence concerns the gene SLC2A4 and breast neoplasm.
