Genetic variation in FGFR2 is a newly described risk factor for breast cancer. We estimated the relative risk and contribution of FGFR2 polymorphisms to breast cancer risk in diverse ethnic groups within Jewish and other Middle Eastern populations. We genotyped four FGFR2 single nucleotide polymorphisms (SNP) and tested for association of these SNPs and haplotypes with breast cancer risk in a p...

Multiple regions of the genome are often amplified during breast cancer development and progression, as evidenced in a number of published studies by comparative genomic hybridization (CGH). However, only relatively few target genes for such amplifications have been identified. Here, we indicate how small-scale commercially available cDNA and CGH microarray formats combined with the tissue micr...

Apert syndrome (AS) is a common genetic syndrome in humans characterized with craniosynostosis. Apert patients and mouse models showed abnormalities in sutures, cranial base and brain, that may all be involved in the pathogenesis of skull malformation of Apert syndrome. To distinguish the differential roles of these components of head in the pathogenesis of the abnormal skull morphology of AS, ...

Dysregulation of Fibroblast Growth Factor Receptor (FGFR) signaling through amplifications, mutations, and gene fusions has been implicated in a broad array of cancers (e.g. liver, gastric, ovarian, endometrial, and bladder). ARQ 087 is a novel, ATP competitive, small molecule, multi-kinase inhibitor with potent in vitro and in vivo activity against FGFR addicted cell lines and tumors. Biochemi...

Alternative splicing of fibroblast growth factor receptor-2 (FGFR2) mutually exclusive exons IIIb and IIIc results in highly cell-type-specific expression of functionally distinct receptors, FGFR2-IIIb and FGFR2-IIIc. We previously identified an RNA cis-element, ISE/ISS-3, that enhanced exon IIIb splicing and silenced exon IIIc splicing. Here, we have performed comprehensive mutational analysis...

A loss of expression of fibroblast growth factor (FGF) receptor 2 IHb (FGFR2IIIb), which responds to stroma-derived FGF, accompanies pro gression of premalignant androgen-responsive rat prostate tumor epithe lial 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 F...

The FGF receptors (FGFR) are tyrosine kinases that are constitutively activated in a subset of tumors by genetic alterations such as gene amplifications, point mutations, or chromosomal translocations/rearrangements. Recently, small-molecule inhibitors that can inhibit the FGFR family as well as the VEGF receptor (VEGFR) or platelet-derived growth factor receptor (PDGFR) family displayed clinic...

The incidence of esophageal adenocarcinoma (EAC) is rising rapidly, and early detection within the precursor state of Barrett's esophagus (BE) is challenged by flat premalignant lesions that are difficult detect with conventional endoscopic surveillance. Overexpression of cell surface fibroblast growth factor receptor 2 (FGFR2) is an early event in progression of BE to EAC, and is a promising i...

Fibroblast growth factor receptor 2 (FGFR2) belongs to the FGFR family, which plays an important role in cell growth, invasiveness, motility and angiogenesis. In human breast cancer, expression of FGFR2 is estrogen receptor (ER)-dependent and correlates with a lower rate of apoptosis. Recently, whole-genome association studies have identified several single-nucleotide polymorphisms (SNPs) of FG...

D missense mutations in the genes encoding fibroblast growth factor receptors (FGFRs) 1–3 are the etiology of many craniosynostosis (premature fusion of the cranial sutures) and chondrodysplasia (dwarfism) syndromes (1–3). Mutations in Fgfr2 cause craniosynostosis syndromes including Crouzon syndrome, Pfeiffer syndrome, and Apert syndrome (AS). The article in this issue of PNAS by Hajihosseini ...
