Dual Action of Sulfated Hyaluronan on Angiogenic Processes in Relation to Vascular Endothelial Growth Factor-A.

Pathological healing characterized by abnormal angiogenesis presents a serious burden to patients' quality of life requiring innovative treatment strategies. Glycosaminoglycans (GAG) are important regulators of angiogenic processes. This experimental and computational study revealed how sulfated GAG derivatives (sGAG) influence the interplay of vascular endothelial growth factor (VEGF) and its heparin-binding domain (HBD) with the signaling receptor VEGFR-2 up to atomic detail.
