Expression of the tumor markers sialyl Lewis A, sialyl Lewis X, Lewis Y, Thomsen-Friedenreich antigen, galectin-1 and galectin-3 in human osteoblasts in vitro.
AIM Lewis antigens and the Thomsen-Friedenreich (TF) antigen are complex glycan structures that modulate processes such as cell adhesion and proliferation and tumor metastasis. The aim of our study was to analyze the expression of sialyl Lewis A (sLeA), sialyl Lewis X (sLeX), Lewis Y (LeY), TF, galectin-1 (Gal-1) and galectin-3 (Gal-3) in human osteoblasts in vitro. MATERIALS AND METHODS The ...
متن کاملColorectal Cancer with Conventional Sialyl Lewis X Expression in Human Expression of Sialyl 6-Sulfo Lewis X Is Inversely Correlated
Sialyl 6-sulfo Lewis X determinant has been described recently as a major ligand for L-selectin on high endothelial venules of human peripheral lymph nodes. From our investigation of its distribution in human colorectal cancer tissues and cultured colon cancer cells, the sialyl 6-sulfo Lewis X determinant was preferentially expressed in the nonmalignant colonic epithelia rather than cancer cell...
متن کاملSelectin Ligands Sialyl-Lewis a and Sialyl-Lewis x in Gastrointestinal Cancers
The tetrasaccharide structures Siaα2,3Galβ1,3(Fucα1,4)GlcNAc and Siaα2,3Galβ1,4(Fucα1,3)GlcNAc constitute the epitopes of the carbohydrate antigens sialyl-Lewis a (sLea) and sialyl-Lewis x (sLex), respectively, and are the minimal requirement for selectin binding to their counter-receptors. Interaction of sLex expressed on the cell surface of leucocytes with E-selectin on endothelial cells allo...

متن کاملSialyl Lewis X and neutrophil aggregation.
We read with great interest the report by Simon et all concerning the obligatory role of& integrin and L-selectin in neutrophil aggregation. Monoclonal antibodies against adhesion molecules (IB4anti CD18 and DREG 200-anti L-selectin) markedly decrease aggregation.’.’ Furthermore. neutrophils from LAD I patients (CD18 deficiency) do not aggregate unless mixed with control cells, validating the r...
