ABSTRACT
This article focuses on the emerging views and concepts concerning the role of cell
surface and extracellular heparan sulfate-like glycosaminoglycans (HSGAGs) in tumor
biology. HSGAGs, found ubiquitously both at the cell surface and in the extracellular
matrix (ECM), play a critical role in regulating tumor initiation, progression, and
metastasis. The diverse biological functions of HSGAGs include the regulation of coagulation,
growth factor signaling, cell adhesion, proliferation, and mobility. HSGAGs, depending
on their location (anchored at the cell surface or soluble as free GAGs), the signaling
molecules they associate with, and their fine structures, can either promote or inhibit
the tumorigenic process.
