Plasticity in interactions of fibroblast growth factor 1 (FGF1) N terminus with FGF receptors underlies promiscuity of FGF1.
Tissue-specific alternative splicing in the second half of Ig-like domain 3 (D3) of fibroblast growth factor receptors 1-3 (FGFR1 to -3) generates epithelial FGFR1b-FGFR3b and mesenchymal FGFR1c-FGFR3c splice isoforms. This splicing event establishes a selectivity filter to restrict the ligand binding specificity of FGFRb and FGFRc isoforms to mesenchymally and epithelially derived fibroblast g...
متن کاملFibroblast Growth Factor-1 vs. Fibroblast Growth Factor-2 in Ischemic Skin Flap Survival in a Rat Animal Model
BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...
متن کاملA Novel Fibroblast Growth Factor-1 (FGF1) Mutant that Acts as an FGF Antagonist
BACKGROUND Crosstalk between integrins and FGF receptors has been implicated in FGF signaling, but the specifics of the crosstalk are unclear. We recently discovered that 1) FGF1 directly binds to integrin alphavbeta3, 2) the integrin-binding site and FGF receptor (FGFR) binding site are distinct, and 3) the integrin-binding-defective FGF1 mutant (R50E) is defective in inducing FGF signaling al...
متن کاملLow expression of FGF1 (fibroblast growth factor-1) in rat parasympathetic preganglionic neurons.
Fibroblast growth factor-1 (FGF1), a member of the FGF family of growth factors, is localized in cholinergic neurons where it has trophic activity. We recently reported that cholinergic neurons in the dorsal motor nucleus of the vagus (DMNV) contain little FGF1, raising the possibility that FGF1 is not localized to parasympathetic preganglionic cholinergic neurons. To clarify this issue, we inv...
متن کاملNucleolin Regulates Phosphorylation and Nuclear Export of Fibroblast Growth Factor 1 (FGF1)
Extracellular fibroblast growth factor 1 (FGF1) acts through cell surface tyrosine kinase receptors, but FGF1 can also act directly in the cell nucleus, as a result of nuclear import of endogenously produced, non-secreted FGF1 or by transport of extracellular FGF1 via endosomes and cytosol into the nucleus. In the nucleus, FGF1 can be phosphorylated by protein kinase C δ (PKCδ), and this event ...
