In vertebrates, Fibroblast Growth Factors (FGFs) and their receptors are involved in various developmental and pathological processes, including neoplasia. The number of FGFs and their large range of activities have made the understanding of their precise functions difficult. Investigating their biology in other species might be enlightening. A sequence(More)
Recent evidence suggests that regulatory pathways might control sustained high levels of FOXP3 in regulatory CD4(+)CD25(hi) T (T(reg)) cells. Based on transcriptional profiling of ex vivo activated T(reg) and helper CD4(+)CD25(-) T (T(h)) cells we have identified GARP (glycoprotein-A repetitions predominant), LGALS3 (lectin, galactoside-binding, soluble, 3)(More)
The expression of NCAM (neural cell adhesion molecule) is precisely regulated in terms of cell type specificity and developmental control. We searched for extracellular factors that may be involved in this regulation using N2A neuroblastoma and NIH 3T3 fibroblastic cells. Factors contained in FBS promoted a two- to threefold increase in NCAM protein and(More)
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(More)
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(More)
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. C. elegans has a single FGFR (EGL-15) with two(More)
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. elegans FGFs, is expressed throughout development and is essential for worm development. It is both expressed(More)
LET-756 is one of the two fibroblast growth factors (FGF) of Caenorhabditis elegans. We have previously shown that worms homozygote for the let-756 null allele (s2887) die at larval stage and that homozygotes for the partial loss-of-function allele (s2613) are viable but shorter than wild-type animals. We now show that expression of let-756 in any region of(More)
