Mutation of FOP/FGFR1OP in mice recapitulates human short rib-polydactyly ciliopathy.

Skeletal dysplasias are a clinically and genetically heterogeneous group of bone and cartilage disorders. A total of 436 skeletal dysplasias are listed in the 2015 revised version of the nosology and classification of genetic skeletal disorders, of which nearly 20% are still genetically and molecularly uncharacterized. We report the clinical and molecular characterization of a lethal skeletal dysplasia of the short-rib group caused by mutation of the mouse Fop gene.

Myomegalin is necessary for the formation of centrosomal and Golgi-derived microtubules.

The generation of cellular microtubules is initiated at specific sites such as the centrosome and the Golgi apparatus that contain nucleation complexes rich in γ-tubulin. The microtubule growing plus-ends are stabilized by plus-end tracking proteins (+TIPs), mainly EB1 and associated proteins. Myomegalin was identified as a centrosome/Golgi protein associated with cyclic nucleotide phosphodiesterase.

Direct and heterologous approaches to identify the LET-756/FGF interactome.

Background: Fibroblast growth factors (FGFs) are multifunctional proteins that play important roles in cell communication, proliferation and differentiation. However, many aspects of their activities are not well defined. LET-756, one of the two C.

Intracellular trafficking of LET-756, a fibroblast growth factor of C. elegans, is controlled by a balance of export and nuclear signals.

The superfamily of fibroblast growth factors (FGF), which counts 22 members in humans, exerts many functions during animal development and adult life. LET-756 is one of the two FGFs of the nematode C. elegans.

An evolutionary history of the FGF superfamily.

Fibroblast growth factors (FGF) are associated with multiple developmental and metabolic processes in triploblasts, and perhaps also in diploblasts. The evolution of the FGF superfamily has accompanied the major morphological and functional innovations of metazoan species. The study of FGFs throughout species shows that the FGF superfamily can be subdivided in eight families in present-day organisms and has evolved through phases of gene duplications and gene losses.

A pair as a minimum: the two fibroblast growth factors of the nematode Caenorhabditis elegans.

Fibroblast growth factors (FGFs) regulate many important developmental and homeostatic physiological events. The FGF superfamily contains several families. In this review, we present recent findings on the two FGFs of the nematode Caenorhabditis elegans from both functional and phylogenic points of view.

Functional phylogeny relates LET-756 to fibroblast growth factor 9.

Fibroblast growth factors (FGFs) are secreted regulatory proteins involved in various developmental processes. In vertebrates, the FGF superfamily comprises 22 members. In non-vertebrates, six FGF genes have been identified in Ciona intestinalis, three in Drosophila melanogaster, and two (let-756 and egl-17) in Caenorhabditis elegans.

Caenorhabditis elegans receptors related to mammalian vascular endothelial growth factor receptors are expressed in neural cells.

Through a genomic survey of the Caenorhabditis elegans genome for genes encoding tyrosine kinase receptors (RTK) we identified a family of four RTKs which are structurally related to vascular endothelial growth factor receptors (VEGFRs). We named this family the ver gene family (for Vascular Endothelial growth factor receptor Related). It was intriguing to find this type of RTK in an animal devoid of a vascular system.
