摘要:Stably transfected PC12 cell lines expressing similar amounts of chimeric receptors composed of the extracellular domain of the human platelet-derived growth factor (PDGF){beta} receptor and the transmembrane and intracellular domains of the fibroblast growth factor receptors (FGFRs) 1, 3, and 4 undergo ligand-induced differentiation. The FGFR1 chimera (PFR1) is the most potent of the three, and PFR4 requires more frequent (every 24 hr) addition of ligand to maintain the response. Both PFR1 and -3 also show significant ligand-independent autophosphorylation but PFR4 does not. All of the chimeras activated phospholipase C{gamma
