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: Fibroblast growth factor (FGF) family signaling mediates cell-to-cell communication in development and organ homeostasis in adults. Of the FGF receptor (FGFR) isotypes, FGFR4 is the sole resident isotype present in mature parenchymal hepatocytes. FGFR1 that is normally associated with activated nonparenchymal cells appears ectopically in hepatoma cells. Ectopic expression and chronic activity of FGFR1 in hepatocytes accelerates diethylnitrosamine (DEN)-initiated hepatocarcinogenesis by driving unrestrained cell proliferation and tumor angiogenesis. Hepatocyte FGFR4 mediates liver's role in systemic cholesterol/bile acid and lipid metabolism and affects proper hepatolobular restoration after damage without effect on cell proliferation. Here we ask whether FGFR4 plays a role in progression of hepatocellular carcinoma (HCC). We report that although spontaneous HCC was not detected in livers of FGFR4-deficient mice, the ablation of FGFR4 accelerated DEN-induced hepatocarcinogenesis. In contrast to FGFR1 that induced a strong mitogenic response and depressed rate of cell death in hepatoma cells, FGFR4 failed to induce a mitogenic response and increased the rate of cell death. FGFR1 but not FGFR4 induced cyclin D1 and repressed p27 expression. Analysis of activation of Erk, JNK, and PI3K-related AKT signaling pathways indicated that in contrast to FGFR1, FGFR4 failed to sustain Erk activation and did not activate AKT. These differences may underlie the opposing effects of FGFR1 and FGFR4. These results suggest that in contrast to ectopic FGFR1 that is a strong promoter of hepatoma, resident FGFR4 that mediates differentiated hepatocyte metabolic functions also serves to suppress hepatoma progression.

TL;DR: It was showed that p53 and FGF1 pathways may interact in the cell to determine cell fate and deregulation of one of these pathways modifies the balance between cell proliferation and cell death and may lead to tumor progression.

...read moreread less

Abstract: We analysed the relationships between p53-induced apoptosis and the acidic fibroblast growth factor 1 (FGF1) survival pathway We found that p53 activation in rat embryonic fibroblasts induced the downregulation of FGF1 expression These data suggest that the fgf1 gene is a repressed target of p53 Unlike extracellular FGF1, which has no effect on p53-dependent pathways, intracellular FGF1 inhibits both p53-dependent apoptosis and cell growth arrest via an intracrine pathway FGF1 increases MDM2 expression at both mRNA and protein levels This increase is associated with an acceleration of p53 degradation, which may partly account for the ability of endogenous FGF1 to counteract p53 pathways In the presence of FGF1, p53 was unable to transactivate bax, but no modification of p21 gene transactivation was observed As Bax is an essential component of the p53-dependent apoptosis pathway, this suggests that intracellular FGF1 inhibits p53 pathways not only by decreasing the stability of p53, but also by modifying some of its transactivation properties In conclusion, we showed that p53 and FGF1 pathways may interact in the cell to determine cell fate Deregulation of one of these pathways modifies the balance between cell proliferation and cell death and may lead to tumor progression

Abstract: The mutated K-ras gene is involved in approximately 30% of human cancers. In order to search for K-ras oncogene-induced modulators in lung tissues of K-ras transgenic mice, we performed microarray and proteomics (LC/ESI-MS/MS) analysis. Genes (RAB27b RAS family, IL-1RA, IL-33, chemokine ligand 6, epiregulin, EGF-like domain and cathepsin) related to cancer development (Wnt signaling pathway) and inflammation (chemokine/cytokine signaling pathway, Toll receptor signaling) were up-regulated while genes (troponin, tropomodulin 2, endothelial lipase, FGFR4, integrin alpha8 and adenylate cyclase 8) related to the tumor suppression such as p53 pathway, TGF-beta signaling pathway and cadherin signaling pathway were down-regulated by K-ras oncogene. Proteomics approach revealed that up-regulated proteins in lung adenomas of K-ras mice were classified as follows: proteins related to the metabolism/catabolism (increased from 7 to 22% by K-ras gene), proteins related to translation/transcription and nucleotide (from 4 to 6%), proteins related to signal transduction (from 3 to 5%), proteins related to phosphorylation (from 1 to 2%). ATP synthase, Ras oncogene family, cytochrome c oxidase, flavoprotein, TEF 1, adipoprotein A-1 BP, glutathione oxidase, fatty acid BP 4, diaphorase 1, MAPK4 and transgelin were up-regulated by K-ras oncogene. However, integrin alpha1, Ras-interacting protein (Rain), endothelin-converting enzyme-1d and splicing factor 3b were down-regulated. These studies suggest that genes related to cancer development and inflammation were up-regulated while genes related to the tumor suppression were down-regulated by K-ras, resulting in the tumor growth. Putative biomarkers such as cell cycle related genes (Cdc37), cancer cell adhesion (Glycam 1, integrin alpha8, integrin alphaX and Clec4n), signal transduction (Tlr2, IL-33, and Ccbp2), migration (Ccr1, Ccl6, and diaphorase 1 (Cyb5r3) and cancer development (epiregulin) can be useful for diagnosis and as prognosis markers and some of the target molecules can be applied for prevention of cancer.

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.
