سرطان پستان، فراوان ترین سرطان در بین زنان می باشد. علت سرطان پستان مجموعه ای از عوامل ژنتیکی، محیطی و سبک زندگی می باشد. مطالعات همراهی کل ژنوم، پلی مورفیسم هایی در ژن fgfr2 را شناسایی کردند که با سرطان پستان همراهی نشان می دهند. ژن گیرنده فاکتور رشد فیبروبلاستی 2 (fgfr2) یکی از اعضای خانواده گیرنده های تیروزین کیناز بوده که پروتئین گیرنده فاکتور رشد فیبروبلاستی را کد می کند. fgfr2 نقش اساسی د...
The receptors 1 and 2 of fibroblast growth factor (FGFR1 and FGFR2, respectively) have been observed in all types of testicular cells. Culture on extracellular matrix (ECM) has been observed to lead to initiation of differentiation in spermatogonial stem cells (SSCs). The present study was carried out to investigate whether FGFR1 and FGFR2 play a role in SSCs differentiation. Following isolatio...
BACKGROUND Fibroblast growth factor receptor 2 (FGFR2) genetic alterations lead to tumor cell proliferation in various types of cancer. We hypothesized that FGFR2 amplification is associated with FGFR2 expression, resulting in tumor growth and poorer outcome in esophagogastric junction (EGJ) adenocarcinoma. PATIENTS AND METHODS A total of 176 consecutive chemo-naive patients with EGJ adenocar...
A reciprocal regulatory circuit between CD44 and FGFR2 via c-myc controls gastric cancer cell growth
Despite their suggested importance, the mechanistic roles of FGFR2 and gastric cancer stem cell (GCSC) marker CD44 remain unclear. We investigated cross talk between CD44 and FGFR2. FGFR2 and CD44 positively regulate each other's expression. While FGFR2 suppresses c-Myc transcription, CD44 activates it. c-Myc in turn augments FGFR2 transcription. CD44 knockdown (KD) depleted FGFR2 and other GCS...
Dysregulated fibroblast growth factor (FGF) signaling has been implicated in the pathogenesis of human cancers. Aberrant activation of FGF receptor 2 (FGFR2) signaling, through overexpression of FGFR2 and/or its ligands, mutations, and receptor amplification, has been found in a variety of human tumors. We generated monoclonal antibodies against the extracellular ligand-binding domain of FGFR2 ...
nloaded regulated fibroblast growth factor (FGF) signaling has been implicated in the pathogenesis of human s. Aberrant activation of FGF receptor 2 (FGFR2) signaling, through overexpression of FGFR2 and/or its s, mutations, and receptor amplification, has been found in a variety of human tumors. We generated lonal antibodies against the extracellular ligand-binding domain of FGFR2 to address t...
PURPOSE FGFR gene aberrations are associated with tumor growth and survival. We explored the role of FGFR2 amplification in gastric cancer and the therapeutic potential of AZD4547, a potent and selective ATP-competitive receptor tyrosine kinase inhibitor of fibroblast growth factor receptor (FGFR)1-3, in patients with FGFR2-amplified gastric cancer. EXPERIMENTAL DESIGN Array-comparative genom...
BACKGROUND Fibroblast growth factor 2 (FGFR2) amplification, occurring in ~2-9% of gastric cancers (GC), is associated with poor overall survival. RESULTS RNA sequencing identified a novel FGFR2-ACSL5 fusion in the resistant tumor that was absent from the matched pre-treatment tumor. The FGFR2-amplified PDC line was sensitive to FGFR inhibitors whereas the PDC line with concomitant FGFR2 ampl...
Gene amplification and protein overexpression of fibroblast growth factor receptor 2 (FGFR2) characterize the SUM-52 breast cancer cell line developed in our laboratory. SUM-52 cells express nine distinct alternatively spliced isoforms of FGFR2. Among these isoforms are two otherwise identical FGFR2 variants that express either the C1 or C3 carboxyl terminus. FGFR2-C3 variants are not normally ...
We identified the IIIb C2 epithelial cell-specific splice variant of fibroblast growth factor receptor 2 (FGFR2 IIIb C2) receptor tyrosine kinase in a screen for activated oncogenes expressed in T-47D human breast carcinoma cells. We found FGFR2 IIIb C2 expression in breast carcinoma cell lines and, additionally, expression of the mesenchymal-specific FGFR2 IIIc splice variant in invasive breas...
