A recently described atypical myeloproliferative disorder is invariably associated with reciprocal translocations involving 8p11-12. The most common rearrangement is a t(8;13)(p11;q11-12). Here we determine that this translocation results in the fusion of the fibroblast growth factor receptor 1 gene (FGFR1), a member of the receptor tyrosine kinase family at 8p11, to a novel gene at 13q11-12 de...

Therapeutic targeting of late-stage breast cancer is limited by an inadequate understanding of how tumor cell signaling evolves during metastatic progression and by the currently available small molecule inhibitors capable of targeting these processes. Herein, we demonstrate that both β3 integrin and fibroblast growth factor receptor-1 (FGFR1) are part of an epithelial-mesenchymal transition (E...

The Fgf8 gene is expressed in developing limb and craniofacial structures, regions known to be important for growth and patterning of the mouse embryo. Although Fgf8 is alternatively spliced to generate at least 7 secreted isoforms that differ only at their mature amino terminus, the biological significance of these multiple isoforms is not known. In this report, we demonstrate that multiple FG...

Influenza A virus causes annual epidemics and occasional pandemics in humans. Here, we investigated four members of the fibroblast growth factor receptor (FGFR) family; FGFR1 to 4, and examined their expression patterns in human lung epithelial cells A549 with influenza A virus infection. We identified a functional role of FGFR1 in influenza A/Puerto Rico/8/1934 (PR8) and A/Anhui/01/2005 (H5N1)...

Ramadan is the Holy month of fasting that is obligatory for all normal Muslims who reached at their puberty. Two meals are taken during Ramadan, one is taken before down to prepare themselves for fast is called “Sahur”, and second meal is taken at sunset is called “Iftar”. Fasting is not only a ritual and religious obligation while it has several medicinal significances specia...

PURPOSE Previous studies have implicated members of the fibroblast growth factor (FGF) and insulin-like growth factor (IGF) families as stimulators of lens fiber cell differentiation in rodent and chicken embryo lenses, respectively. In the present study, the role of FGFs in fiber cell differentiation and epithelial cell proliferation in chicken embryos was examined. METHODS Lenses were injec...

Fibroblast growth factor receptors (FGFRs), a subfamily of receptor tyrosine kinases, are aberrant in various cancer types, and considered to be promising targets for cancer therapy. We started with a weak-active compound that was identified from our internal hepatocyte growth factor receptor (also called c-Met) inhibitor project, and optimized it with the guidance of a co-crystal structure of ...

Spinal cord injury (SCI) is a severe condition that affects many people and results in high health care costs. Therefore, it is essential to find new targets for treatment. The fibroblast growth factor receptor 1 (FGFR1) signalling pathway has a history of being explored for SCI treatment. Several groups have examined the effect of high availability of different FGFR1 ligands at the injury site...

A loss of expression of fibroblast growth factor (FGF) receptor 2 IIIb (FGFR2IIIb), which responds to stroma-derived FGF, accompanies progression of premalignant androgen-responsive rat prostate tumor epithelial cells to the malignant phenotype. Concurrently, the level of FGFR2 gene expression is reduced and lost altogether in over 30% of cells, whereas all malignant cells abnormally express FG...
