Deciphering the mechanism behind Fibroblast Growth Factor (FGF) induced biphasic signal-response profiles

Fibroblast Growth Factor-1 (FGF-1)

Nuclear Translocation of fibroblast growth factor (FGF) receptors in response to FGF-2

Members of the FGF family of growth factors localize to the nuclei in a variety of different cell types. To determine whether FGF receptors are also present within nuclei and if this localization is regulated by FGFs, nuclei were prepared from quiescent and FGF-2-treated Swiss 3T3 fibroblasts and examined for the presence of FGF receptors by immunoblotting with an antibody produced against the ...

Platelet factor 4 modulates fibroblast growth factor 2 (FGF-2) activity and inhibits FGF-2 dimerization.

Platelet factor 4 (PF-4) inhibits angiogenesis in vitro and in vivo. The mechanism of inhibition is poorly understood. We have investigated the mechanism of inhibition by examining the interaction of PF-4 and the fibroblast growth factor-2 (FGF-2)/fibroblast growth factor receptor (FGFR) system. PF-4 inhibited the binding of FGF-2 to high-affinity and low-affinity binding sites in murine microv...

The role of basic-fibroblast growth factor (b-FGF) in cyclosporine-induced nephrotoxicity.

BACKGROUND The effect of the b-fibroblast growth factor (b-FGF) on cyclosporine A (CsA)-induced nephrotoxicity in the rat kidney was investigated. MATERIALS AND METHODS The rats were divided into six groups: A (control), B (b-FGF-treated), C, D: (CsA-treated and sacrificed on days 14 or 21), E, F (Cs A- and b-FGF- treated and sacrificed on days 14 or 21). The antibody mouse anti-rat CD31 was ...

Fibroblast growth factor (FGF) signaling in development and skeletal diseases.

Fibroblast growth factors (FGF) and their receptors serve many functions in both the developing and adult organism. Humans contain 18 FGF ligands and four FGF receptors (FGFR). FGF ligands are polypeptide growth factors that regulate several developmental processes including cellular proliferation, differentiation, and migration, morphogenesis, and patterning. FGF-FGFR signaling is also critica...
