Native fibroblast growth factor receptor (FGFR) function was inhibited in developing Xenopus retinal ganglion cells (RGCs) by in vivo transfection of a dominant negative FGFR. Axons expressing the dominant negative protein advanced at 60% of the normal speed, but nevertheless navigated appropriately in the embryonic optic pathway. When they neared the optic tectum, however, many axons made erro...
Fibroblast growth factor receptors (FGFRs) mediate a wide spectrum of cellular responses that are crucial for development and wound healing. However, aberrant FGFR activity leads to cancer. Activated growth factor receptors undergo stimulated endocytosis, but can continue to signal along the endocytic pathway. Endocytic trafficking controls the duration and intensity of signalling, and growth f...
Expression of the fibroblast growth factor (FGF)-1, FGF-2, fibroblast growth factor receptor (FGFR)-1, and FGFR-2 genes has been reported in various cancers and is associated with poor outcomes in patients with solid tumors. This study examined the relations between the relative expression of the FGF genes and clinicopathological factors, especially invasion and metastasis, in patients with col...
Our laboratory has previously shown that some gefitinibinsensitive head and neck squamous cell carcinoma (HNSCC) cell lines exhibit dominant autocrine fibroblast growth factor receptor (FGFR) signaling. Herein, we deployed a wholegenome loss-of-function screen to identify genes whose knockdown potentiated the inhibitory effect of the FGFR inhibitor, AZ8010, in HNSCC cell lines. Three HNSCC cell...
Fibroblast growth factor receptor-2 (FGFR-2) plays an important role in tumorigenesis. In thyroid cancer it has been observed a FGFR-2 down-modulation, but the role of this receptor has not been yet clarified. Therefore, we decided to examine the expression of both FGFR-2 isoform, FGFR-2-IIIb and FGFR-2-IIIc, in different histological thyroid variants such as hyperplasia, follicular adenoma and...
The current working model for fibroblast growth factor receptor (FGFR) dimerization and activation requires the assembly of a ternary complex of fibroblast growth factor (FGF), FGFR, and heparin or heparan sulfate proteoglycan (HSPG) on the plasma membrane. The recent FGF2-FGFR1-heparin crystal structure provides a detailed but static view of the FGF-FGFR-heparin complex. However, the kinetics ...
Purpose: FGFR gene aberrations are associated with tumor growth and survival. We explored the role of FGFR2 amplification in gastric cancer and the therapeutic potential of AZD4547, a potent and selective ATPcompetitive receptor tyrosine kinase inhibitor of fibroblast growth factor receptor (FGFR)1–3, in patients with FGFR2-amplified gastric cancer. Experimental Design: Array-comparative genomi...
In an attempt to enhance cytotoxic activity of pyrazolo[3,4-d]pyrimidine core, we synthesized (3,5-dimethylpyrazol-1-yl)-[4-(1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-ylamino)phenyl]methanone (4) by reacting 4-(1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-ylamino)benzohydrazide (3) with acetylacetone. Antiproliferative activity of this compound was screened against breast (MCF-7), colon (HCT-116), and l...
