Heparan Sulfate Domains Required for Fibroblast Growth Factor 1 and 2 Signaling through Fibroblast Growth Factor Receptor 1c.
A small library of well defined heparan sulfate (HS) polysaccharides was chemoenzymatically synthesized and used for a detailed structure-activity study of fibroblast growth factor (FGF) 1 and FGF2 signaling through FGF receptor (FGFR) 1c. The HS polysaccharide tested contained both undersulfated (NA) domains and highly sulfated (NS) domains as well as very well defined non-reducing termini. Th...
متن کاملEffect of Basic Fibroblast Growth Factor on Achilles Tendon Healing in Rabbit
BACKGROUND Tendon injuries are common and it takes a long time for an injured tendon to heal. Adverse phenomena such as adhesion and rupture are associated with these injuries. Finding a method to reduce the time required for healing whichimproves the final outcome, will lead to decreased frequency and intensity of adverse consequences. This study was designed to investigate the effects ...
متن کاملHeparin increases the affinity of basic fibroblast growth factor for its receptor but is not required for binding.
The role of heparin or heparan sulfates in the interaction of basic fibroblast growth factor (bFGF) with its high affinity receptor were investigated using purified extracellular ligand-binding region of FGF receptor-1 (FGFR-1) and intact receptors expressed in a myeloid cell line (32D) that does not express detectable levels of heparan sulfate proteoglycans or in Chinese hamster ovary (CHO) ce...
متن کاملAnalysis of high-affinity binding determinants in the receptor binding epitope of basic fibroblast growth factor.
Basic fibroblast growth factor (bFGF) is implicated in the pathogenesis of several vascular and connective diseases. A key step in the discovery of bFGF receptor antagonists to mitigate these actions is to define the functional epitope required for receptor binding of the growth factor. In previous studies, we identified Glu96 as an essential residue in this epitope using site-directed mutagene...
متن کاملDifferential structural requirements of heparin and heparan sulfate proteoglycans that promote binding of basic fibroblast growth factor to its receptor.
Heparan sulfate proteoglycans (HSPG) are obligatory for receptor binding and mitogenic activity of basic fibroblast growth factor (bFGF). The capacity of various species of heparin and heparan sulfate (HS) to promote bFGF receptor binding was investigated using both Chinese hamster ovary mutant cells deficient in cell surface HSPG and a soluble bFGF receptor-alkaline phosphatase fusion protein....
