Genomically amplified fibroblast growth factor receptor 1 (FGFR1) is an oncogenic driver in defined lung cancer subgroups and predicts sensibility against FGFR1 inhibitors in this patient cohort. The FGFR inhibitor nintedanib has recently been approved for treatment of lung adenocarcinoma and is currently evaluated for small cell lung cancer (SCLC). However, tumor recurrence due to development ...
Chromosomal translocations and activation of the fibroblast growth factor (FGF) receptor 1 (FGFR1) are a feature of stem cell leukemia–lymphoma syndrome (SCLL), an aggressive malignancy characterized by rapid transformation to acute myeloid leukemia and lymphoblastic lymphoma. It has been suggested that FGFR1 proteins lose their ability to recruit Src kinase, an important mediator of FGFR1 sign...
The fibroblast growth factor receptor (FGFR) family of receptor tyrosine kinases has been implicated in a wide variety of cancers. Despite a high level of sequence homology in the ATP-binding site, the majority of reported inhibitors are selective for the FGFR1-3 isoforms and display much reduced potency toward FGFR4, an exception being the Bcr-Abl inhibitor ponatinib. Here we present the cryst...
Basic fibroblast growth factor (bFGF) and fibroblast growth factor receptor 1 (FGFR1) are associated with drug resistance in lung cancer. In the present study, mouse monoclonal antibodies (mAb) against human bFGF, targeting the binding site of bFGF with FGFR1 were produced, and the antitumor activity and inhibition of metastasis was studied in Lewis lung carcinoma (LLC). A total of four hybrido...
Glioblastomas were examined for abnormalities in fibroblast growth factor receptor (FGFR) expression by polymerase chain reaction and immunocytochemical analysis. Polymerase chain reaction analysis demonstrated that FGFR1 mRNA levels were significantly higher in glioblastomas than in normal brain adjacent to the tumor or in untransformed human brain. These results were consistent with immunocyt...
PURPOSE Constitutive activation of ERK1/2 controls proliferation of uveal melanoma cells. Because an autocrine fibroblast growth factor (FGF) activation loop controls ERK1/2 activation in many cancers, this study was conducted to examine the role of the FGF/FGF receptor autocrine loop in the ERK1/2-dependent proliferation and survival of uveal melanoma cells. METHODS Primary tumors and cell l...
PURPOSE We previously showed that Discs large-1 (Dlg-1) regulates lens fiber cell structure and the fibroblast growth factor receptor (Fgfr) signaling pathway, a pathway required for fiber cell differentiation. Herein, we investigated the mechanism through which Dlg-1 regulates Fgfr signaling. METHODS Immunofluorescence was used to measure levels of Fgfr1, Fgfr2, and activated Fgfr signaling ...
INTRODUCTION Cartilage degeneration driven by catabolic stimuli is a critical pathophysiological process in osteoarthritis (OA). We have defined fibroblast growth factor 2 (FGF-2) as a degenerative mediator in adult human articular chondrocytes. Biological effects mediated by FGF-2 include inhibition of proteoglycan production, up-regulation of matrix metalloproteinase-13 (MMP-13), and stimulat...
