TLDR
Members of the FGF family function in the earliest stages of embryonic development and during organogenesis to maintain progenitor cells and mediate their growth, differentiation, survival, and patterning.Abstract:
The signaling component of the mammalian Fibroblast Growth Factor (FGF) family is comprised of eighteen secreted proteins that interact with four signaling tyrosine kinase FGF receptors (FGFRs) Interaction of FGF ligands with their signaling receptors is regulated by protein or proteoglycan cofactors and by extracellular binding proteins Activated FGFRs phosphorylate specific tyrosine residues that mediate interaction with cytosolic adaptor proteins and the RAS-MAPK, PI3K-AKT, PLCγ, and STAT intracellular signaling pathways Four structurally related intracellular non-signaling FGFs interact with and regulate the family of voltage gated sodium channels Members of the FGF family function in the earliest stages of embryonic development and during organogenesis to maintain progenitor cells and mediate their growth, differentiation, survival, and patterning FGFs also have roles in adult tissues where they mediate metabolic functions, tissue repair, and regeneration, often by reactivating developmental signaling pathways Consistent with the presence of FGFs in almost all tissues and organs, aberrant activity of the pathway is associated with developmental defects that disrupt organogenesis, impair the response to injury, and result in metabolic disorders, and cancer © 2015 Wiley Periodicals, Incread more

TL;DR: Treatment with subcutaneously administered pegbelfermin for 16 weeks was generally well tolerated and significantly reduced hepatic fat fraction in patients with non-alcoholic steatohepatitis, and the full planned sample size was not needed.

Fibroblast growth factor signaling in skeletal development and disease
TL;DR: Progress made on understanding the functions of the FGF signaling pathway during critical stages of skeletogenesis is examined, and the mechanisms by which mutations in FGF signalling molecules cause skeletal malformations in humans are explored.
Journal ArticleDOI
The molecular basis of endothelial cell plasticity
TL;DR: The endothelium is capable of remarkable plasticity in the embryo and in the adult, maintenance of differentiated endothelial state is an active process requiring constant signalling input that leads to the development of endothelial-to-mesenchymal transition that plays an important role in pathogenesis of a number of diseases.

TL;DR: A framework for classifying tumours is proposed that holds promise for enabling clinicians to personalize optimal interventions based on the evolvability of the patient's tumour, and the Evo- and Eco-indices provide a common lexicon for communicating about how neoplasms change in response to interventions.

Gradients of signalling in the developing limb
TL;DR: The progress zone model for specifying proximo-distal pattern, involving timing to provide cells with positional information, continues to be challenged, and there is further evidence that graded signalling by retinoic acid specifies the proximal part of the limb.

TL;DR: A novel TC mutation is identified, a lysine (K) substitution for glutamine (Q) (160 C>A) at residue 54 (Q54K) is reported and a common defect of reduced FGF23 stability for all known F GF23-TC mutants is demonstrated.
