We present the first preparation of microarrays containing synthetic heparin oligosaccharides in order to elucidate the heparin-protein interactions involved in a variety of biological processes. For this purpose, we have developed a novel linker strategy that is compatible with the protecting-group manipulations required for the synthesis of the highly sulfated oligosaccharides and can also be...
Fibroblast growth factor (FGF) signaling regulates mammalian development and metabolism, and its dysregulation is implicated in many inherited and acquired diseases, including cancer. Heparan sulfate glycosaminoglycans (HSGAGs) are essential for FGF signaling as they promote FGF.FGF receptor (FGFR) binding and dimerization. Using novel organic synthesis protocols to prepare homogeneously sulfat...
Maximal stimulation of DNA synthesis in quiescent rat mammary (Rama) 27 fibroblasts is elicited by epidermal growth factor (EGF) or basic fibroblast growth factor (bFGF) 18 h after the initial addition of the growth factors-the 'lag' period. At maximally-stimulating concentrations, EGF and bFGF are interchangeable 9 h after their initial addition. When the initial concentration of growth factor...
Fibroblast Growth Factor-2 Induces Hepatocyte Growth Factor/Scatter Factor Expression in Osteoblasts
Methods. Proliferating human RPE cells were exposed to varying concentrations of exogenous basic fibroblast growth factor (bFGF) or epidermal growth factor (EGF) at different media oxygen tensions (16 to 147 mm Hg) and cell counts determined after 4 days. Receptor expression was determined by affinity cross-linking and saturation binding studies on confluent RPE cultures exposed to varying medi...
the role of angiogenic molecules, like vascular endothelial growth factor (vegf) and fibroblast growth factor (fgf) in tumor angiogenesis was well confirmed. photodynamic therapy (pdt) action is, to very high degree, based on tumor vasculature damage. therefore, it seemed to be important to evaluate growth factor receptors after pdt. the extent of receptor expression was studied by immuno-histo...
In most cases, induced pluripotent stem (iPS) cells must be maintained by replacing basic fibroblast growth factor (bFGF)-containing medium daily to inhibit spontaneous differentiation. However, complete inhibition of differentiation is difficult to achieve even with frequent replacement of medium because of bFGF instability. Here, we established a novel system for the sustained release of bFGF...
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...
Katanin is a heterodimeric enzyme that severs and disassembles microtubules. While the p60 subunit has the enzyme activity, the p80 subunit regulates the p60 activity. The microtubule-severing activity of katanin plays an essential role in axonal growth. However, the mechanisms by which neuronal cells regulate the expression of katanin-p60 remains unknown. Here we showed that USP47 and C termin...
