Fig. 7 shows that 12 genes were expressed solely in the highly tumorigenic S2N cells and 5 genes were not. The exclusively expressed genes include the EMT inducer CAMK1D, the stem cell maintenance gene ZBTB16, tumorigenicity related FAM65B and FKBP5 as well as an invasion facilitating non-voltage Na+ channel SCNN1G (Fig. 7A). Genes not expressed in the highly tumorigenic cells encompass the EMT process inhibiting DAB2 and LAMB3 which is frequently inactivated in breast cancer cells increasing their invasiveness (Fig. 7B). Here, RIPOR2 is linked to breast cancer.
