Sialyl Lewis x (sLex) is a well known selectin ligand involved in metastasis. The molecular bases of its overexpression in colon cancer are still unclear. Here we show that FucT-VI is the main fucosyltransferase responsible for sLex biosynthesis in colonic tissues and a major regulator of sLex expression in colon cancer because: 1) in colon cancer specimens and cell lines sLex expression correlates with the activity of a fucosyltransferase able to fucosylate 3’ sialyllactosamine (3’SLN) at a low (0.5 mM) acceptor concentration. 2) In cells transiently transfected with FucT genes only FucT-VI displays this property. 3) In normal and cancer colon, FucT-VI transcript shows the highest level of expression (about 200 fg/pg actin, vs. 30 for FucT-III, 10 for FucT-IV |
