TLDR
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.read more

FGF signaling in flies and worms: More and more relevant to vertebrate biology
Peng Huang,Michael J. Stern +1 more
TL;DR: Recent work has shown that the pleiotropies of these FGF receptors resemble those of their vertebrate counterparts, and, in many cases, serve as excellent models for understanding the fundamental molecular mechanisms controlling these events.

FGF-2 Transcriptionally Down-Regulates the Expression of BNIP3L via PI3K/Akt/FoxO3a Signaling and Inhibits Necrosis and Mitochondrial Dysfunction Induced by High Concentrations of Hydrogen Peroxide in H9c2 Cells.
TL;DR: The present results demonstrate that FoxO3a is an important transcription factor that acts by binding to the promoter and promoting the transcription of BNIP3L, and it contributes to the necrosis and mitochondrial dysfunction induced by H2O2 in H9c2 cardiomyoblast cells.

TL;DR: The development and characterization of a panel of anti-FGFR4 MAbs that were generated in mice using a rapid immunization protocol demonstrate that the RIMMS strategy is an effective approach for generating class-switched, high-affinity MAbs in mice to evolutionarily conserved proteins such as human FGFR4.

TL;DR: KM1334 possesses strong blocking activity in vitro and antitumor activity in vivo and therefore may be an effective therapeutic candidate for the treatment of cancers that are dependent on FGF8b signaling for growth and survival.

Cell surface, heparin-like molecules are required for binding of basic fibroblast growth factor to its high affinity receptor.
TL;DR: It is demonstrated that free heparin and heparan sulfate can reconstitute a low affinity receptor that is, in turn, required for the high affinity binding of bFGF.

TL;DR: This work highlights conserved protein domains that act as key regulatory participants in many of these different signalling pathways in multicellular organisms.

TL;DR: It is demonstrated that FGF 1 is the only FGF that can activate all FGF receptor splice variants and the relative activity of all the other members of the FGF family is determined.
