MGAT5 and lung cancer: Previous studies have reported that some glycosyltransferases and glycosidases within TGF-β pathway are tightly related to phosphorylation of TGF-β receptors, such as fucosyltransferase 8 (FUT8) in lung cancer [23] and sialylated N-acetylglucosaminyl-transferase V (MGAT5, 37) in CRC [24].
