Overexpression of CD15 or CD15s epitopes led to increased adhesion of cancer cells to cerebral endothelial cells compared with wild-type and cells with silenced CD15 or CD15s (p < 0.01); this increased adhesion could potentiate the transmigration of circulating NSCLC cells into the brain [27]. Here, FUT4 is linked to non-small cell lung carcinoma.
