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(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)
FGFs (fibroblast growth factors) play major roles in a number of developmental processes. Recent studies of several human disorders, and concurrent analysis of gene knock-out and properties of the corresponding recombinant proteins have shown that FGFs and their receptors are prominently involved in the development of the skeletal system in mammals. We have(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)
The HIV and visna lentiviruses induce an inflammatory reaction in the central nervous system (CNS) of the infected hosts leading to dysmyelination, demyelination, and neuronal loss. The basic domain of the transactivating Tat protein has been involved in CNS damage. Infusion of basic containing domain Tat peptides in the lateral ventricle (systemic(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)
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. Re-introduction of LET-756 in a null mutant strain restores viability, allowing the study of structural requirements for LET-756 trafficking and(More)
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)
Transmembrane receptors with tyrosine kinase activity (RTK) constitute a superfamily of proteins present in all metazoans that is associated with the control and regulation of cellular processes. They have been the focus of numerous studies and are a good subject for comparative analyses of multigene families in different species aimed at understanding(More)
Analyzing the nuclear DNA from ancient human bones is an essential step to the understanding of genetic diversity in current populations, provided that such systematic studies are experimentally feasible. This article reports the successful extraction and amplification of nuclear DNA from the beta-globin region from 5 of 10 bone specimens up to 12,000 years(More)
