GCNT3 and neoplasm: In the same study, we profiled glycosyltransferase expression levels in the different tumor cell subsets and discovered a remarkable up-regulation of the gene GCNT3, encoding a mucin-type core 2/ core 4 β1,6-N-acetylglucosaminyltransferase (GCNT3), in the sLeA/X-positive GI adenocarcinoma cells.
