General description

FGFR1 (fibroblast growth factor receptor 1) is one of the four variants of FGFR, the ligand of which are the FGF polypeptides. FGFRs are highly conserved in nature, and the variants differ in their intracellular kinase and extracellular ligand-binding domains. It is a receptor tyrosine kinase localized to the human chromosome 8p12.

Biochem/physiol Actions

Studies in genetically modified mice show that the epithelial-stromal interaction mediated by FGFR1 and FGF are responsible for the pathophysiology of prostate cancer. The antitumor property of dovitinib is mediated by the inhibition of FGFR1 signaling in prostate cancer to prevent bone metastasis. In malignant pleural mesothelioma (MPM), FGFR1 mRNA levels are elevated, though the gene is not amplified. FGFR1 autocrine signaling is implicated in the tumorigenesis of MPM, and thus, FGFR1 pathway has potential as a therapeutic target in the same. This gene is amplified in squamous cell lung cancer, head and neck squamous cell cancer (HNSCC) and breast cancer.
