Fibroblast growth factor receptor 2 (FGFR2)-targeted therapy has attracted considerable attention as novel anticancer agents in gastric cancer (GC). However, intrinsic or acquired drug resistance has emerged as a major challenge to their clinical use. In this study, we demonstrated that several receptor tyrosine kinase (RTK), including EGFR, HER3 and MET, activations contributed to AZD4547 (a s...
Advanced cholangiocarcinoma continues to harbor a difficult prognosis and therapeutic options have been limited. During the course of a clinical trial of whole genomic sequencing seeking druggable targets, we examined six patients with advanced cholangiocarcinoma. Integrated genome-wide and whole transcriptome sequence analyses were performed on tumors from six patients with advanced, sporadic ...
The normal cellular organization and layering of the vertebrate cerebellum is established during embryonic and early postnatal development by the interplay of a complex array of genetic and signaling pathways. Disruption of these processes and of the proper layering of the cerebellum usually leads to ataxic behaviors. Here, we analyzed the relative contribution of Fibroblast growth factor recep...
A closed hyperbolic Riemann surfaceM is said to beK-quasiconformally homogeneous if there exists a transitive family F of K-quasiconformal homeomorphisms. Further, if all [f ] ⊂ F act trivially on H1(M ;Z), we say M is Torelli-K-quasiconformally homogeneous. We prove the existence of a uniform lower bound on K for Torelli-K-quasiconformally homogeneous Riemann surfaces. This is a special case o...
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...
Previously, we identified Fgfr2 as the major Fgf receptor in liver specification. Expression of Hhex in the liver was reduced in Fgfr2 morphants. Unexpectedly, we found the relative position of the liver and pancreas were disrupted. In addition to visceral organs, we found the heart was randomized in Fgfr2 morphants. Expression patterns of genes controlling laterality including Spaw, lefty1 and...
Fibroblast growth factor (FGF) signaling is cardioprotective in various models of myocardial infarction. FGF receptors (FGFRs) are expressed in multiple cell types in the adult heart, but the cell type-specific FGFR signaling that mediates different cardioprotective endpoints is not known. To determine the requirement for FGFR signaling in endothelium in cardiac ischemia-reperfusion injury, we ...
Fibroblast Growth Factor (FGF) and Transforming Growth Factor beta (TGFbeta) are key regulators of bone development. Constitutively activating mutations of FGF Receptors (FGFR) 1-3 result in craniosynostosis, premature fusion of cranial sutures. The aim of this thesis was to determine how FGF signalling is impaired in osteoblasts with the mutation FGFR2-C278F, known to induce craniosnostosis an...
Mutations in the fibroblast growth factor-receptor gene 2 (FGFR2) gene have been implicated in numerous diseases, including nevus comedonicus (NC) and naevoid acne that have somatic missense mutations in FGFR2 in the affected tissue. A patient presented in our department with unusual, innumerable large comedones throughout his back reminiscient of NC, as well as multifocal hidradenitis suppurat...
Somatic mutations in FGFR2 are present in 4% to 5% of patients diagnosed with non-small cell lung cancer (NSCLC). Amplification and mutations in FGFR genes have been identified in patients with NSCLCs, and clinical trials are testing the efficacy of anti-FGFR therapies. FGFR2 and other FGFR kinase family gene alterations have been found in both lung squamous cell carcinoma and lung adenocarcino...
