A potential role for 6-sulfo sialyl Lewis X in metastasis of bladder urothelial carcinoma

Our findings indicate that 6-sulfo sLeX glycans likely play 2 roles in bladder urothelial carcinoma progression: one in lymphocyte recruitment to enhance antitumor immune responses, and the other in E-selectin-mediated tumor cell adhesion to vascular endothelial cells, which is potentially associated with metastasis.
