TL;DR: FGF signaling also appears to play a role in tumor growth and angiogenesis, and autocrine FGF signaling may be particularly important in the progression of steroid hormone-dependent cancers to a hormone-independent state.

Abstract: Fibroblast growth factors (FGFs) are small polypeptide growth factors, all of whom share in common certain structural characteristics, and most of whom bind heparin avidly. Many FGFs contain signal peptides for secretion and are secreted into the extracellular environment, where theycan bind to the heparan-like glycosaminoglycans (HLGAGs) of the extracellular matrix (ECM). From this reservoir, FGFs mayact directlyon target cells, or theycan be released through digestion of the ECM or the activityof a carrier protein, a secreted FGF binding protein. FGFs bind specific receptor tyrosine kinases in the context of HLGAGs and this binding induces receptor dimerization and activation, ultimatelyresulting in the activation of various signal transduction cascades. Some FGFs are potent angiogenic factors and most playimportant roles in embry onic development and wound healing. FGF signaling also appears to playa role in tumor growth and angiogenesis, and autocrine FGF signaling maybe particularlyimportant in the progression of steroid hormone-dependent cancers to a hormone-independent state.

Abstract: The fibroblast growth factors (FGFs) are important for embryo development, wound healing, hematopoiesis, and angiogenesis. FGF-1, a member of FGF family, is involved in both receptor-dependent pathways and an intracrine pathway. Studies have recently shown that FGF-1 is overexpressed in the early stages of several kinds of cancer. Thus, FGF-1 is a candidate for cancer immunotargeting. To study the potential use of therapeutic antibodies against FGF-1, a monoclonal hybridoma 1C9 secreting monoclonal antibody specific for FGF-1 was developed. Then, a single-chain variable fragment (scFv) antibody was genetically engineered from hybridama 1C9. The binding of the scFv1C9 to the antigen FGF-1 was demonstrated by ELISA and immunoprecipitation assays. Functional analysis showed that the overexpressed scFv1C9 in MCF-7 cells targeted endogenous FGF-1 and prevented the translocation of FGF-1 into the nucleus, resulting in the blockade of the intracrine pathway of FGF-1, which caused the G1 arrest by p21 up-regulation. These results suggest that the generated scFv1C9 is an effective inhibitor of the intracrine pathway of FGF-1 and has a potential application as anti-tumoral agent in breast cancer. © 2011 IUBMB IUBMB Life, 63(2): 129–137, 2011

TL;DR: In this paper, it was shown that pleiotrophin binds to and activates a pleiotophin-receptor, which is responsible for the events associated with the activation of this receptor including tumorigenesis, cell proliferation, and cell invasion.

Abstract: This invention relates to the discovery that pleiotrophin binds to and activates a pleiotrophin-receptor which is responsible for the events associated with pleiotrophin activity including tumorigenesis, cell proliferation, and cell invasion. By interfering with that association, the cascade of events associated with pleiotrophin activity can be prevented or reversed. Further, by evaluating the effect of different compounds and conditions on the interaction, new drugs and treatments can be identified for use in preventing certain cancers and growth and developmental disorders.

TL;DR: FGFR3IIIc may have the potential to be an early-stage tumor marker and a molecular target for ESCC therapy and the knockdown of endogenous FGFR3 using siRNA treatment significantly abrogated cell proliferation and the overexpression of FGFR 3IIIc in cells with enhanced cell proliferation.

Abstract: Deregulated expression of fibroblast growth factor receptors (FGFRs) and their ligands plays critical roles in tumorigenesis. The gene expression of an alternatively spliced isoforms of FGFR3, FGFR3IIIc, was analyzed by RT-PCR in samples from patients with esophageal carcinoma (EC), including esophageal squamous cell carcinoma (ESCC) and adenocarcinoma (EAC). The incidence of FGFR3IIIc was higher in EC [12/16 (75%); p=0.073] than in non-cancerous mucosa (NCM) [6/16 (38%)]. Indeed, an immunohistochemical analysis of early-stage ESCC showed that carcinoma cells expressing FGFR3IIIc stained positively with SCC-112, a tumor marker, and Ki67, a cell proliferation marker, suggesting that the expression of FGFR3IIIc promotes cell proliferation. We used EC-GI-10 cells endogenously expressing FGFR3IIIc as a model of ESCC to provide mechanistic insight into the role of FGFR3IIIc in ESCC. The knockdown of endogenous FGFR3 using siRNA treatment significantly abrogated cell proliferation and the overexpression of FGFR3IIIc in cells with enhanced cell proliferation. EC-GI-10 cells and ESCC from patients with EC showed endogenous expression of FGF2, a specific ligand for FGFR3IIIc, suggesting that the upregulated expression of FGFR3IIIc may create autocrine FGF signaling in ESCC. Taken together, FGFR3IIIc may have the potential to be an early-stage tumor marker and a molecular target for ESCC therapy.

TL;DR: It is shown that the Xenopus homolog of mammalian SNT1/FRS‐2 (XSNT1) plays a critical role in the appropriate formation of mesoderm‐derived tissue during embryogenesis and is required for early Xenopus development.

...read moreread less

Abstract: The docking protein SNT1/FRS2 (fibroblast growth factor receptor substrate 2) is implicated in the transmission of extracellular signals from several growth factor receptors to the mitogen-activated protein (MAP) kinase signaling cascade, but its biological function during development is not well characterized. Here, we show that the Xenopus homolog of mammalian SNT1/FRS-2 (XSNT1) plays a critical role in the appropriate formation of mesoderm-derived tissue during embryogenesis. XSNT1 has an expression pattern that is quite similar to the fibroblast growth factor receptor-1 (FGFR1) during Xenopus development. Ectopic expression of XSNT1 markedly enhanced the embryonic defects induced by an activated FGF receptor, and increased the MAP kinase activity as well as the expression of a mesodermal marker in response to FGF receptor signaling. A loss-of-function study using antisense XSNT1 morpholino oligonucleotides (XSNT-AS) shows severe malformation of trunk and posterior structures. Moreover, XSNT-AS disrupts muscle and notochord formation, and inhibits FGFR-induced MAP kinase activation. In ectodermal explants, XSNT-AS blocks FGFR-mediated induction of mesoderm and the accompanying elongation movements. Our results indicate that XSNT1 is a critical mediator of FGF signaling and is required for early Xenopus development. © 2002 Wiley-Liss, Inc.

Abstract: Communication between cells assumes particular importance in multicellular organisms. The growth, migration and differentiation of cells in the embryo, and their organization into specific tissues, depend on signals transmitted from one cell to another. In the adult, cell signalling orchestrates normal cellular behaviour and responses to wounding and infection. The consequences of breakdowns in this signalling underlie cancer, diabetes and disorders of the immune and cardiovascular systems. Conserved protein domains that act as key regulatory participants in many of these different signalling pathways are highlighted.

Abstract: Thalidomide is a potent teratogen causing dysmelia (stunted limb growth) in humans. We have demonstrated that orally administered thalidomide is an inhibitor of angiogenesis induced by basic fibroblast growth factor in a rabbit cornea micropocket assay. Experiments including the analysis of thalidomide analogs revealed that the antiangiogenic activity correlated with the teratogenicity but not with the sedative or the mild immunosuppressive properties of thalidomide. Electron microscopic examination of the corneal neovascularization of thalidomide-treated rabbits revealed specific ultrastructural changes similar to those seen in the deformed limb bud vasculature of thalidomide-treated embryos. These experiments shed light on the mechanism of thalidomide's teratogenicity and hold promise for the potential use of thalidomide as an orally administered drug for the treatment of many diverse diseases dependent on angiogenesis.
