Báo cáo khoa học: Alpha 1,3-fucosyltransferase-VII regulates the signaling molecules of the insulin receptor pathway

Two H7721 human hepatocarcinoma cell lines showing moderate and high expression of a1,3-fucosyltransferase (FucT)-VII cDNA were established and designated FucTVII-M and FucTVII-H, respectively. In a1,3-FucT-VII-transfected cells, expression of insulin receptor (InR)a- and bsubunits and epidermal growth factor receptor (EGFR) on the cell surface and in cells, as well as the sialyl Lewis X (SLe x , the product of a1,3-FucT-VII) content of the EGFR were unchanged.
