For instance, SOX30 is able to repress tumor metastasis in lung cancer by regulating the Wnt signaling pathway (8); SOX30 also plays an anti-metastatic role in ovarian cancer through modulating the epithelial-mesenchymal transition (EMT) process (9); it has been illustrated that SOX30 has the capacity of inhibiting proliferation and invasion but promoting apoptosis of T24 and 5,673 cells to suppress the progression of bladder cancer (12). This evidence concerns the gene SOX30 and ovarian cancer.
