In breast cancer cells, TGF-β-induced EMT was inhibited upon GCNT2 inhibition [71]; in esophageal squamous cell carcinoma, overexpression of GCNT2 induced migration and invasion and EMT [72]; in colon cancer cells, EMT induced by EGF or bFGF was associated with up-regulation of GCNT2 through down-regulation of miR-199a/b-5p [73]. Here, GCNT2 is linked to breast cancer.
