Abstract
Expression of N-acetylglucosaminyltransferase V (GnT-V) in colon cancer has been shown to be related to hematogenous metastasis and poor prognosis. To investigate the mechanism by which cancer cells expressing GnT-V metastasize to distant organs, we established GnT-Voverexpressing DLD-1 and WiDr cells (human colon cancer cell lines) by transfecting them with a GnT-V expression vector. Attachment to endothelial cells expressing E-selectin was studied, and expression of the E-selectin ligand, sialyl Lewis x, in colon cancer cells was investigated. Both of the cell lines showed reduced adhesion to fibronectin as compared with mock transfectants. In contrast, attachment to human umbilical vein endothelial cells expressing E-selectin was significantly enhanced by GnT-V expression (p
