As shown in Figure 1, expression of SLC39A1, SLC39A3, SLC39A4, SLC39A5, SLC39A6, SLC39A7, SLC39A9, SLC39A10, SLC39A11 and SLC39A13 was significantly higher in cancer tissue than which in normal tissue; however, SLC39A8 and SLC39A14 were expressed higher in normal tissue. This evidence concerns the gene SLC39A7 and cancer.
