The fibroblast growth factor/fibroblast growth factor receptor (FGF/FGFR) signaling pathway plays crucial roles in cell proliferation, angiogenesis, migration, and survival. Aberration in FGFRs correlates with several malignancies and disorders. FGFRs have proved to be attractive targets for therapeutic intervention in cancer, and it is of high interest to find FGFR inhibitors with novel scaffo...

Chondrosarcoma is a rare malignancy characterized by the production of cartilage matrix, displaying heterogeneous histopathology and clinical behavior. Due to lack of effective treatment for advanced disease, the clinical management of metastatic chondrosarcoma is exceptionally challenging. Chondrosarcomas harbor molecular abnormalities, such as overexpression of platelet-derived growth factor ...

To assess the role of fibroblast growth factor (FGF) signaling in pulmonary function in the postnatal period, we generated transgenic mice in which a soluble FGF receptor (FGFR-HFc) was conditionally expressed in respiratory epithelial cells of the mouse lung, thereby inhibiting FGF activity. Although FGFR-HFc did not alter postnatal lung morphogenesis, male FGFR-HFc transgenic mice were more s...

In the developing spinal cord and telencephalon, ventral patterning involves the interplay of Hedgehog (Hh), Retinoic Acid (RA) and Fibroblast Growth Factor (FGF) signaling. In the eye, ventral specification involves Hh signaling, but the roles of RA and FGF signaling are less clear. By overexpression assays in Xenopus embryos, we found that both RA and FGF receptor (FGFR) signaling ventralize ...

Tumor cells with genetic amplifications or mutations in the fibroblast growth factor receptor (FGFR) family are often addicted to FGFR and heavily dependent on its signaling to survive. Although it is critical to understand which signaling pathway downstream of FGFR plays an essential role to guide the research and development of FGFR inhibitors, it has remained unclear partly because the tool ...

Fibroblast growth factor (FGF)2, FGF4, FGF7 and FGF20 are representative paracrine FGFs binding to heparan-sulfate proteoglycan and fibroblast growth factor receptors (FGFRs), whereas FGF19, FGF21 and FGF23 are endocrine FGFs binding to Klotho and FGFRs. FGFR1 is relatively frequently amplified and overexpressed in breast and lung cancer, and FGFR2 in gastric cancer. BCR-FGFR1, CNTRL-FGFR1, CUX...

Fibroblast growth factor (FGF) family plays key roles in development, wound healing, and angiogenesis. Understanding of the molecular nature of interactions of FGFs with their receptors (FGFRs) has been seriously limited by the absence of structural information on FGFR or FGF-FGFR complex. In this study, based on an exhaustive analysis of the primary sequences of the FGF family, we determined t...
