Texto completoDystonia is a movement control disorder characterized by involuntary muscle contractions. The genetic causes of this disease are multiple. I have created databases " loci-specific " collecting all allelic diversity available in the literature for 16 dystonia genes. The goal of this work is to to assist in the diagnosis of this disease and in the longer term, when there are sufficient data, to establish genotype-phenotype correlations. This was the case for the THAP1 gene (responsible for DYT6 dystonia) for which we have described several correlations.I searched for the disease gene in several families using exome sequencing. I identified a pathogenic mutation in the predicted gene ANO3 (DYT23) carried by one family. Another family carries a mutation in a splice site of ATP1A3 (DYT12) resulting in the total retention of intron 17. In another family a candidate gene was identified: ADD2 gene, coding beta adducin. Several functional results were obtained. First, overexpression of wild type and mutated ADD2 enabled to view differences in the actin cytoskeleton. Indeed the overexpression of the wild type protein causes abnormal behavior of actin at the level of stress fibers and at the plasma membrane. Besides, learning by association studies in a Caenorhabditis elegans model KO for ADD2 gene have shown a long-term default memory compared to the wild type. This confirms the involvement of the protein in neuronal plasticity. My thesis work led to further knowledge about the contribution of each gene already known in dystonia , as well as broaden the genetic heterogeneity characteristic of this disease by identifying a new candidate gene

Texto completoThis thesis focuses on characterizing the molecular and metabolic heterogeneity of glioblastomas (GB). We identified seven distinct subclasses of GB, each characterized by unique regulatory activities, as well as by specific molecular and biological characteristics. Integrating transcriptomic, metabolomic and extracellular flux analyses, along with the evaluation of specific regulatory activities, we characterized the heterogeneity of GB stem cells (GSC) and their plasticity depending on their cellular state (stem, differentiated) or the microenvironment (normoxia, hypoxia, chemotherapy). The assessment of their sensitivity to temozolomide revealed an intrinsic resistance in glycolytic GSC and the emergence of acquired resistance in response to environmental stimuli. Our findings highlight the importance of targeting autophagy and oxidative stress to overcome chemotherapy resistance, and reinforce the need for personalized therapeutic approaches adapted to the heterogeneity and plasticity of GB

Texto completoOvarian cancer is characterized by a high mortality rate, linked among other things to a late diagnosis. Significant chemoresistance is observed at the same time as a high rate of recurrence. Epithelial to Mesenchymal Transition (EMT) is one of the factors observed in cell chemoresistance and cancer progression. It involves a loss of adhesion to the Extracellular Matrix (ECM) and intercellular junctions, in favor of a gain in motility or the invasive potential of the cells. EMT is a pathophysiological phenomenon that has a high degree of plasticity. These cells, known as intermediates, may present both epithelial and mesenchymal characteristics and define a spectrum of EMT. These cells are often correlated with a worse prognosis for life. Omics methods, particularly transcriptomic methods, exist in the characterization of these intermediate cells. However, these methods are often expensive, laborious, and do not take into account morphology at scale of the cell, or cell arrangement in space, which are important elements in EMT. To this end, we have developed a phenomics approach based exclusively on microscopy.This approach works on FIJI using a macro algorithm, ready to use or modifiable according to the user's expertise or needs. In the study of EMT in ovarian cancer, we studied four representative lines of the EMT spectrum. EMT is induced by the use of two cytokines, TNFα and TGFβ1, whose associative effect remains context-dependent and has not been described or only slightly described in ovarian cancer. Thanks to our analysis pipeline, we characterize cell plasticity by a single-cell analysis, including the morphology and the different molecular labelling performed related to the EMT. We analysed more than seventy thousand cells and combined over fifty parameters via FIJI, Celltool, and designed methods. These include a cell topography tool to normalize the distance between the nucleus and the cell membrane, or to measure cell isolation within its environment. This set of parameters was then reduced to a single statistical measure for comparison between and within the different cell lines. We were then able to effectively distinguish the four lineages from each other, as well as the impact of cytokines by line. We thus demonstrate the additivity of cytokines in the induction of EMT in each lineage along the EMT spectrum. In parallel with this study, our methodology has already demonstrated the importance of ECM on the dissemination of ovarian cancer in the presence of ascitic flow. These results show that a single-cell phenomics analysis is particularly promising for characterizing heterogeneity as well as plasticity in response to a microenvironment

Texto completoPediatric cancers represent a therapeutic challenge, and an understanding of the mechanisms of escape from treatment is necessary in order to be able to develop new therapeutic approaches. Circulating DNA can be released by a tumor in bodily fluids and enable to detect and follow genetic alterations in tumors by successive minimally invasive samples such as a blood test. In this work, a “whole exome” sequencing technique for circulating DNA was developed to allow the study of genetic tumor alterations in plasma in children with cancer. These analyzes highlight the frequent spatial and temporal genetic heterogeneity of pediatric cancers. In addition, an important role of clonal evolution in the progression of the disease was thus highlighted. Approaches using the particular characteristics of circulating DNA have also made it possible to infer the expression profile, based on the imprint of the transcription start sites, or the epigenetic profile of the tumor. In addition to an aid in the classification of tumors, these features may help to observe a change in cellular identity under treatment. Circulating DNA is therefore an important tool for better understanding mechanisms of escape from treatment of a tumor based on spatial and temporal heterogeneity and cellular plasticity

Texto completoThe plasticity of alpha-titanium is strongly anisotropic. It involves slip systems families with various properties and different kinds of twins. In this study, tensile tests on commercially pur alpha-titanium samples are coupled with acoustic emission and high-resolution extensometry measurements. These tests show the presence of a well on the strain dependence of the work hardening. An opposite strain rate effect on the well depth is found whether specimens are elongated along the rolling or the transverse direction of the initially laminated sheet. Slip lines analysis reveals an initial predominance of prismatic slip, particularly pronounced in specimens strained along the rolling direction. The relative activity of prismatic slip is then observed to decrease with the deformation of both kinds of samples. The twin volume fractions are higher in the tests performed in the transverse direction but still remain very low (< 5 %), especially around the well (< 2 %). These results provide grounds for elaboration of a model capable of explaining such peculiar work hardening behavior. The model relies on a self-consistent scheme in elastoviscoplasticity, based on the translated field method and an affine linearization of the viscoplastic flow rule. The model considers crystal plasticity and deals separately with mobile dislocation density and dislocation velocity. It assumes lower strain rate sensitivity as well as higher dislocation multiplication rate for prismatic systems. Based on these assumptions, the model reproduces correctly the stress-strain curves and gives sound estimates of Lankford coefficients, prismatic slip activity and textures evolution. Most importantly, the opposite effect of strain rate on the well depth with regard to the orientation of the tensile axis is qualitatively retrieved, which allows putting forward an explanation of the observed phenomena. Besides, acoustic emission and high-resolution extensometry measurements allow analyzing the intermittent and wave nature of alpha-titanium at a mesoscopic scale. These data are confronted with the predictions of the present model and will be used as grounds for the future development of a more complex model
