Kusy, Sophie. "Régulation de l'expression et fonction anti-tumorale de la sémaphorine SEMA3F." Poitiers, 2005. http://www.theses.fr/2005POIT2288.
Full textOur group cloned the SEMA3F gene in the 3p21. 3 chromosomic region. It is a secreted protein initially implicated in the cellular migration. Our aims were to study the regulation of SEMA3F expression and to verify its anti-tumoral rule in the animal. We have mapped the promoter of SEMA3F, localized the transcriptional initiation sites within the CpG-island and defined the region necessary for transcriptional activation. The methylation of SEMA3F and the chromatin remodeling are implicated in this regulation. We also have studied the expression and the biological properties of the two spliced forms of SEMA3F during the maturation of the mouse brain. Although functionally redundant, these forms are characterized by a temporal and regional specific regulation. Finally, we have described the anti-tumoral activity of SEMA3F into the lungs of nude rats. The neuropilin 2, integrins and MAPKinases seem to be implicated in this effect

Full textSegregation distorters are selfish genetic elements that promote their own transmission by subverting the meiotic process to their advantage. The spread of an X-linked distorter (Sex-Ratio) in populations results in an excess of females, which triggers a genetic conflict between the X chromosome and the rest of the genome. Such conflicts are important drivers of genome evolution, but little is known about the molecular nature and the function of the Sex Ratio selfish elements. The first chapter of this manuscript is a review of the current knowledge about X-linked segregation distorters. Then, I present my work on the « Paris » Sex Ratio system of Drosophila simulans, in which two distorter elements on the X chromosome co-operate to prevent Y chromosome sister chromatids segregation during meiosis II. I mapped a gene in one of the distorter loci and achieved the functional validation of its involvement in sex-ratio distortion. It is a young and rapidly evolving gene that belongs to a well-known gene family involved in chromatin state regulation. It emerged through duplication about 15-22 Myrs ago and has experienced multiple independant cis-duplications, loss or pseudogenization throughout its evolutionary history. This suggests that this gene could have been involved in multiple genetic conflicts. Finally, the last chapter is about an opening study of the strucural diversity of Y chromosomes in relation to « Paris » segregation distorter. These findings should help understanding the molecular basis of genetic conflicts and the evolutionary impact of heterochromatin regulation during meiosis

Full textMyeloid malignancies are clonal disease of the hematopoietic stem cell develop following a skewed of the differentiation toward myeloid lineages associated with increased proliferation. Recently, many studies have demonstrated the involvement epigenetic factors in malignant transformation. Indeed, DNA sequencing of patients with diverse malignancies identified mutations in TET2 (TET methylcytosïne dioxygenase 2) gene. This gene encodes an enzyme that couverts 5-methylcytosines to 5-hydroxyméthylcytosines (5hmC). The biological impact of this new modification of DNA bases and the TET protein function during hematopoiesis is poorly understood. The objectives of my thesis were to determine the function(s) of TET2 in human hematopoiesis and involvement in malignant transformation. My results confirmed in the cells from MPN patients that TET2 mutation induces a decrease in the overall rate of 5hmC. Then we hâve shown that TET2 haploinsufficiency after infection of CD34+ using a specific shRNA induces differentiation skewed toward myeloid lineage. This haploinsufficiency also affects the terminal stages of myeloid three lineages. We also demonstrated that TET2 inhibition induces expression of several inflammatory cytokines such as MIF (Macrophage Migration Inhibitory Factor}. TET2 binds to it promoter regions and influence their transcription through the recruitment of EGR1 and active polymerase II. Finally, haploinsufficiency of TET2 induces a selective advantage of CD34+ cells for reconstitution of the hematopoietic System of highly immunodeficient mice. TET2 is involved in several steps of tumor transformation but these functions factor transcription remain poorly understood

Full textAquaporins are water channel proteins which facilitate the diffusion of water across cell membranes. These proteins define a large multigenic family with 35 members in Arahidopsis thaliana. In a first part of this work, we addressed the relevance of aquaporin regulation by cytoplasmic pH at the root level, and especially in stress conditions. Cytoplasmic pH and root water transport were followed using NMR and pressure chamber techniques, respectively. Results indicate that a cytoplasmic acidification was associated to a strong, rapid and reversible diminution of the hydraulic conductivity of Arabidopsis excised root systems. A same behavior was observed, whether acidification was induced by means of weak acid diffusion, cell treatment with respiratory drugs, or anoxia. A second aspect of this work concerns the analysis of 6 aquaporin single knockout mutants in Arabidopsis. These mutants concern the PIP sub-family and were obtained after insertion of the T-DNA from Agrobacterium tumefaciens. No growth or developmental phenotype could be observed for any of the mutant plants in any of the conditions investigated. The expression pattern of the PIP2;2 et PIP2;3 genes in roots was determined by GUS reporter gene analyses. In two PIP2;2 mutant lines, the hydraulic conductivity of root cortex cells and whole root systems was diminished by 25 % and 14 %, respectively. Altogether, our results point to a predominant function for PIP2;2 in maintaining efficient water uptake in response to small osmotic gradients within the root. The identification of a function for a specific aquaporin isoform discards the idea of a total functional redundancy within the aquaporin family. In conclusion, our work brings novel insights into general and specific aspects of aquaporin function in plant roots

Full textThe pathogenesis of type 2 diabetes (T2D) is complex, with two distinct mechanisms: insulin resistance and insulin deficiency. These abnormalities are due to genetic and environmental factors. To allow a better understanding of T2D aetiology, we have undertaken the identification of genetic variants implied in the development of the disease, using 2 approaches: - a genome wide scan for T2D in diabetic Japanese sib-pairs revealed 2 linked regions at loci 3q26-q28 and 15q13-q21 where are located respectively APM1 and CX36 genes - genetic studies of KCNJ11, encoding the sub-unit of the channel Kir6. 2, and PDX-1, b cell pancreatic specific transcription factor were investigated in different French diabetic groups. We found activating mutations responsible for a neonatal form of diabetes and frequent variants implicated in mechanisms leading to an ordinary T2D
