Sialylation of β1 Integrins Blocks Cell Adhesion to Galectin-3 and Protects Cells against Galectin-3-induced Apoptosis

In previous studies, we determined that β1 integrins from human colon tumors have elevated levels of α2-6 sialylation, a modification added by β-galactosamide α-2,6-sialyltranferase I (ST6Gal-I). Intriguingly, the β1 integrin is thought to be a ligand for galectin-3 (gal-3), a tumor-associated lecti...
