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: Hepatocellular carcinoma (HCC) is the sixth most common type of cancer, with an increasing mortality rate. Aberrant expression of fibroblast growth factor 19–fibroblast growth factor receptor 4 (FGF19–FGFR4) is reported to be an oncogenic-driver pathway for HCC patients. Thus, the FGF19–FGFR4 signaling pathway is a promising target for the treatment of HCC. Several pan-FGFR (1–4) and FGFR4-specific inhibitors are in different phases of clinical trials. In this review, we summarize the information, recent developments, binding modes, selectivity, and clinical trial phases of different available FGFR4/pan-FGF inhibitors. We also discuss future perspectives and highlight the points that should be addressed to improve the efficacy of these inhibitors.

Abstract: Purpose: Synovial sarcoma is a soft tissue sarcoma, the growth regulatory mechanisms of which are unknown. We investigated the involvement of fibroblast growth factor (FGF) signals in synovial sarcoma and evaluated the therapeutic effect of inhibiting the FGF signal. Experimental Design: The expression of 22 FGF and 4 FGF receptor (FGFR) genes in 18 primary tumors and five cell lines of synovial sarcoma were analyzed by reverse transcription-PCR. Effects of recombinant FGF2, FGF8, and FGF18 for the activation of mitogen-activated protein kinase (MAPK) and the growth of synovial sarcoma cell lines were analyzed. Growth inhibitory effects of FGFR inhibitors on synovial sarcoma cell lines were investigated in vitro and in vivo. Results: Synovial sarcoma cell lines expressed multiple FGF genes especially those expressed in neural tissues, among which FGF8 showed growth stimulatory effects in all synovial sarcoma cell lines. FGF signals in synovial sarcoma induced the phosphorylation of extracellular signal–regulated kinase (ERK1/2) and p38MAPK but not c-Jun NH2-terminal kinase. Disruption of the FGF signaling pathway in synovial sarcoma by specific inhibitors of FGFR caused cell cycle arrest leading to significant growth inhibition both in vitro and in vivo. Growth inhibition by the FGFR inhibitor was associated with a down-regulation of phosphorylated ERK1/2 but not p38MAPK, and an ERK kinase inhibitor also showed growth inhibitory effects for synovial sarcoma, indicating that the growth stimulatory effect of FGF was transmitted through the ERK1/2. Conclusions: FGF signals have an important role in the growth of synovial sarcoma, and inhibitory molecules will be of potential use for molecular target therapy in synovial sarcoma.

TL;DR: It is suggested that VEGF has positive effects on odonto-/osteogenic differentiation in vitro and on the formation of mineralized structure in vivo and exogenous FGF-2 might inhibit terminal differentiation.

Abstract: Human periodontal ligament stem cells (PDLSCs) from extracted third molar teeth are a type of adult stem cell originating from dental tissue. PDLSCs are known to have a self-renewal capacity and multi-lineage differentiation potential. Vascular endothelial growth factor (VEGF), an angiogenic/vasculogenic factor, has been shown to stimulate endothelial cell mitogenesis and cell migration. Another growth factor, fibroblast growth factor-2 (FGF-2), a mitogenic factor, enhances osteogenesis in mesenchymal stem cells (MSCs). This study examines the effects of VEGF and FGF-2 on PDLSCs in vitro and in vivo compared with those on bone marrow stem cells (BMSCs) as a positive control. Treatment of PDLSCs with VEGF increases the accumulation of calcium nodules, alkaline phosphatase (ALP) activity and the formation of hard tissue and up-regulates the mRNA level of runt-related transcription factor 2 (Runx2). In contrast, FGF-2 enhances the proliferation of PDLSCs in vitro in cell culture, where it significantly decreases calcium accumulation and ALP activity and down-regulates the expression of osteogenic gene markers (i.e., Runx2, ALP, type I collagen) involved in osteogenic induction. We have also transplanted PDLSCs with hydroxyapatite/tricalcium phosphate particles (HA/TCP) as carriers for each factor (VEGF, FGF-2) into nude mice and, after 8 weeks, observed the in vivo formation of hard tissue at the dorsal surface. Based on our results, we suggest that VEGF has positive effects on odonto-/osteogenic differentiation in vitro and on the formation of mineralized structure in vivo. FGF-2 might be a powerful promoter of the proliferation of progenitor cells in hard tissue regeneration but exogenous FGF-2 might inhibit terminal differentiation.

TL;DR: The αB crystallin sequences that interacted with FGF-2, NGF-β, VEGF, insulin, and β-catenin overlapped with sequences that selectively interact with partially unfolded proteins, suggesting a common function for αB crystalsin in chaperone activity and the regulation of cell growth and differentiation.

...read moreread less

Abstract: Protein pin arrays assessed interactions between alphaB crystallin and 12 regulatory proteins, including EGF, FGF-2, IGF-1, NGF-beta, TGF-beta, VEGF, insulin, beta-catenin, caspase-3, caspase-8, Bcl-2, and Bcl-xL, which are important in cellular differentiation, proliferation, signaling, cytoskeletal assembly, and apoptosis. FGF-2, NGF-beta, VEGF, insulin, and beta-catenin had strong interactions with human alphaB crystallin peptides, and the alphaB crystallin interactive sequences for these proteins were identified. The seven remaining proteins (EGF, IGF-1, TGF-beta, caspase-3, caspase-8, BCl-2, and Bcl-xL) did not interact with alphaB crystallin. The alphaB crystallin sequences that interacted with FGF-2, NGF-beta, VEGF, insulin, and beta-catenin overlapped with sequences that selectively interact with partially unfolded proteins, suggesting a common function for alphaB crystallin in chaperone activity and the regulation of cell growth and differentiation. Chaperone assays conducted with full-length alphaB crystallin and synthetic alphaB crystallin peptides confirmed the ability of alphaB crystallin to protect against the aggregation of FGF-2 and VEGF, suggesting that alphaB crystallin protects these proteins against unfolding and aggregation under conditions of stress. This is the first report in which sequences involved in interactions with regulatory proteins, including FGF-2, NGF-beta, VEGF, insulin, and beta-catenin, were identified in a small heat shock protein.

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.
