- Heparan sulfate (HS) is a structurally complex polysaccharide that interacts with a broad spectrum of extracellular effector ligands and thereby is thought to regulate a diverse array of biologic processes. The specificity of HS-ligand interactions is determined by the arrangement of sulfate groups on HS, which creates distinct binding motifs. Biologically important HS motifs are expected to exhibit regulated expression. Yet, there is a profound lack of tools to identify such motifs; consequently, little is known of their structures and functions. We have identified a novel phage display-derived antibody (NS4F5) that recognizes a highly regulated HS motif (HS(NS4F5)), which we have rigorously identified as (GlcNS6S-IdoA2S)(3). HS(NS4F5) exhibits a restricted expression in healthy adult tissues. Blocking HS(NS4F5) on cells in culture resulted in reduced proliferation and enhanced sensitivity to apoptosis. HS(NS4F5) is upregulated in tumor endothelial cells, consistent with a role in endothelial cell activation. Indeed, TNF-α stimulated endothelial expression of HS(NS4F5), which contributed to leukocyte adhesion. In a mouse model of severe systemic AA amyloidosis, HS(NS4F5) was expressed within amyloid deposits, which were successfully detected by microSPECT imaging using NS4F5 as a molecularly targeted probe. Combined, our results demonstrate that NS4F5 is a powerful tool for elucidating the biological function of HS(NS4F5) and can be exploited as a probe to detect novel polysaccharide biomarkers of disease processes.
