Full textThe yeast Saccharomyces cerevisiae is the first eucaryote whose genome was fully sequenced. The analysis of its genomic sequence has led to the discovery of 6293 ORF, which might correspond to genes allowing yeast autonomous life. 70 % of these ORF correspond to potential new genes. The functional analysis of the ORF YBR260c was initiated. It showed that this ORF corresponded to a S. Cerevisiae gene, which was named RGD1 for Related GAP Domain. The Rgd1 protein acts in vitro as a GTPase Activating Protein (GAP) for the yeast Rho3 and Rho4 small G proteins. Using a genetic screen, a synthetic lethal interaction between RGD1 and VRO1 genes was discovered. The VRP1 gene encodes a protein named verproline, which is homologous to human WIP protein. The verproline is an actin and myosins interacting protein involved in polarized growth. Characterization of RGD1-VRP1 genetic interaction revealed the implication of the Rho3 and Rho4 proteins, two members of the Ras superfamily. The results obtained using mutant forms of Rho3p and Rho4p are in favour of Rho3p and Rho4p being the targets of Rgd1p RhoGAP activity in vivo. Genetic and functional analyses made it possible to enlighten cellular relationships between VRP1, RGD1, RHO3 or RHO4 and cytoskeleton-linked genes, in particular the yeast counterpart of human WASP gene, LAS17. These results allow us to present a biological model. A proteic complex, including Vr1p, would act in concert with a signalling pathway defined by the Rho3 and Rho4 proteins to participate in polarized cell growth. Rgd1p, via its GAP activity, would act as a negative regulator of the Rho3/Rho4 pathway

Full textMy research is entitled "Molecular analysis of consanguineous families Tunisian and Lebanese with clinical signs of Charcot-Marie-Tooth disease". The objectives of the PhD research were to identify and localize the genes implicated in these clinic forms of CMT and to elucidate the functional impact of mutations and the associated physiopathology mechanisms. For this purpose several technologies were used such as Fluorescent Direct Sequencing of known genes published in CMT disease. We have identified two novel mutations in patients from consanguineous Tunisian families: the first mutation (c.514_514insG; p.Ala172Glyfs*27) was detected in FGD4 by Fluorescent direct sequencing. Skin and nerve biopsy structure of these patients were studied under a microscope. Furthermore, the expression profile of FRABIN was studied by western blot. The cellular localization of this protein is under further examinations with the use of immunofluorescent. The second mutation (c.2968delC; p.Leu990Trpfs*24) was identified using High throughput sequencing in the SH3TC2 gene, The duplication of CMT1A in patients from Tunisia was demonstrated by Array CGH technique. The identified mutations will be subjected to functional studies to determine their impact on protein and to investigate the pathophysiology of this disease. Detail data analysis is currently underway for these projects using High throughput sequencing and other methods as appropriate in both Tunisian and Lebanese families

Full textCharcot-Marie-Tooth neuropathy type 4H (CMT4H) is an inherited, autosomal recessive, peripheral neuropathy characterized by demyelination of sensory-motor nerves and due to mutations in FGD4. FGD4 encodes FRABIN, a GDP/GTP nucleotide exchange factor (GEF), specific for the GTPase Cdc42, composed of five functional domains: an N-terminal F-actin binding (FAB) domain, one Dbl homology (DH) domain, two pleckstrin homology (PH) domains, and one cysteine-rich FYVE domain.The main goal of my project is to understand the mechanisms leading to the pathology in CMT4H. To this purpose, I studied both cellular and mouse models.First, molecular screening of FGD4 allowed us to identify two additional mutations in FGD4. We also demonstrated a complete absence of the 105 kDa FRABIN isoform in patients homozygous for splicing and frameshift mutations, which unexpectedly was related to abnormally high levels of Cdc42 activation.The study of a mouse model with conditional ablation of fgd4 in Schwann cells, that we have generated, demonstrates the presence of abnormal myelin outfoldings in sciatic nerves from KO mice, which might be linked to decreased levels of Cd42 in mouse sciatic nerves. Finally, altered recycling of transferrin receptors in patients, with complete absence of FRABIN described above, as well as the identification of SNX3, a protein involved in endosomal trafficking, as a partner for FRABIN are new elements that I provide in favour of a role for FRABIN in membrane and cellular trafficking.Still, there are many points to understand, notably the relation between the RhoGTPase and the endosomal pathways, and the study of our models will help answer these questions

Full textActin cytoskeleton organisation and dynamics are regulated by different types of actin-binding proteins. Recently, novel actin filament crosslinkers involved in the formation of parallel bundles have been characterized in both plants and animals: the two LIM domain-containing (LIM) proteins. In plants, these proteins can be divided into two sub-families whose members differ in their expression pattern. The WLIM sub-family members are widely expressed in vegetative tissues (WLIMs) whereas the PLIM subfamily members (PLIMs) are highly and almost exclusively expressed in pollen grains. An important question that remained to be answered is: why do plants have several proteins of this family and are the different members functionally distinct, or do they share one or several functions? To address these issues, we characterised and compared the actin regulatory activities of all six LIM proteins from Arabidopsis. Confocal analyses of transgenic Arabidopsis plants expressing individual GFP- fused LIM proteins and in vitro biochemical assays demonstrate that all the Arabidopsis LIM proteins are “true” actin-binding proteins able to directly interact with the actin cytoskeleton. In addition, all six Arabidopsis LIM proteins retain the ability to stabilize actin filaments and to trigger the formation of thick actin bundles in vitro as well as in transgenic LIM-expressing plants. Interestingly, in vitro investigations suggest that the members of WLIM and PLIM subfamilies are differentially regulated. Indeed, only PLIM respond to changes in pH and [Ca2+]. Whereas the modification of these parameters has no significant effects on WLIM activities, an increase of pH or [Ca2+] markedly inhibits PLIM activities. These data are strongly supported by live cell experiments in which we artificially modulated the cytoplasmic pH and [Ca2+] of cells derived from the transgenic LIM-overexpressing plants. The C-terminal domain of PLIMs has been identified as necessary for their regulation by pH and Ca2+

Full textGap junctions (GJ), specialised areas of membrane where intercellular channels (IC) are clustered, mediates the direct cell-to-cell exchange of small cytoplasmic molecules and of inorganic ions. In the heart, GJ form low-resistance pathway for cell-to-cell conduction of electrical impulses which mediates the synchronisation of electrical and mechanical activities. Dysfunctions of these GJ induce arrhythmias. In this study we demonstrate that actin cytoskeleton is involved in regulation of GJ channels made of connein 43. Regulation of GJ communication by phosphorylation/dephosphorylation processes can occur by dephosphorylating directly connexin 43 or a regulatory protein associated with gap junction channels. We also show that the metabolic inhibitor antymincine A, is able to directly interrupt cell-to-cell communication, even both ATP and calcium concentrations are kept stable
