- W1504197390 abstract "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) cell mutants defective in heparan sulfate synthesis. The purified extracellular domain of FGFR-1 formed complexes with 125I-bFGF both in the presence or absence of heparin. Intact FGFR-1 expressed in 32D cells also bound the same amount of 125I-bFGF in the presence or absence of heparin when saturating concentrations of bFGF were used. Varying the concentration of 125I-bFGF showed that heparin increased the amount of 125I-bFGF bound at low bFGF concentrations and increased the affinity of bFGF for its receptor by about 3-fold. To eliminate the possibility of alteration of bFGF properties through the chemical modification reactions, bFGF was labeled biosynthetically. The binding of biosynthetically labeled bFGF to FGFR-1 also did not require heparin. When FGFR-1 or FGFR-2 were expressed in mutant CHO cells deficient in heparan sulfate synthesis, the cells also bound 125I-bFGF in the absence of heparin, and the addition of heparin increased the affinity of bFGF for its receptors 2-3-fold. Thus, heparin or heparan sulfate is not required for the binding of bFGF to its receptors but increases the binding affinity to a moderate degree. Finally, the requirement for heparin in signal transduction through the receptor was investigated. Expression of c-fos mRNA was induced by bFGF in 32D cells expressing FGFR-1 to the same extent in the presence or absence of heparin." @default.
