Full textEmergence over the last few years of high throughput technologies like DNA microarray and more recently next generation sequencing now allows an exhaustive analysis of genome with several regulation levels including expression measure of all cell genes, DNA – transcription factors interactions, and also DNA methylation. It thus becomes indispensable to integrate these different data to be able to understand and then to model all these mechanisms involved in global cell function. This understanding will then enable to apprehend the sources of deregulation involved in many pathologies. The goal of my PhD is to understand the impact of PRC (PGC-1 Related Coactivator) transcriptional coactivator on the coordination of mitochondrial and cellular proliferation, from human tumor cell line XTC. UC1, rich in mitochondria. To do so, PRC and transcription factors ERRa, NRF1, GABP, CREB and YY1 involved in these two processes have been studied with ChIP-chip. Positive genes for these transcription factors are then compared with transcriptome of the same cells under siRNA PRC effects. Integration of these different data of transcriptome and ChIP-chip, coupled with study of motifs discovery, will allow to construct the transcriptional regulatory networks necessary to the understanding of PRC pathways. These networks will make possible the detection of therapeutic targets allowing to correct pathological condition

Full textThe complete human genome sequence has contributed to the expansion of genomics. This field notably describes how a genome is expressed, how some sets of genes and their products work together in biological systems. High-throughput technologies for genome research, like microarrays which were used in this thesis, were set up. This work deals with transcriptomic variations observed in different physiological or pathological conditions. We appreciated the effect of genetic and environmental factors on expression profiles, to detect biomarkers specific to pathological subclasses of lymphoma and thyroid lesions. To understand molecular mechanisms underlying these gene expression modifications, we integrated gradually other genomic data. This included detections of genomic deletions or amplifications using CGH arrays, or the identification of transcription factor binding sites by sequence analysis or by ChIP-chip methodology. With this combined approach, modeling biological networks modeling is then conceivable. It will allow a better understanding of a biological system and to detect more reliable therapeutic targets

Full textAscomycetous oleaginous yeasts are among the highest known producers of lipids of our era that may supply lipids compounds, derived chemicals and organic acids from simple or complex carbon sources. We chose oleaginous yeasts species of Blastobotrys genus for defining a new model organism for fatty acid production and lipids, because these oleaginous yeasts natively produce higher lipids rate than Yarrowia lipolytica in the same conditions and can metabolize glucose and xylose. Most of the metabolic engineering studies on these yeast species focused on other molecules compounds than lipids. We characterized the oleaginous traits of two strains belonging to two different species of genus Blastobotrys, using glucose, xylose, glycerol, fructose, cellobiose, sucrose, galactose, starch and oleic acid as substrates with a C/N ratio of 60. We found the higher lipid production (35%) on cellobiose and glucose (32%).Next, in order to further understand the lipid metabolism in Blastobotrys, we explored the effect of temperature on cell physiology, lipid production and lipid profile using YNB medium with 30 g/L glucose. No markedly transition were found from the hyphae to budding form or reversely on YNB medium under four temperatures (28°C, 37°C, 42°C, 45°C). The lipids production is favored at 28°C and C18:1 is the most abundant fatty acid in the lipid profile. We successfully transformed the yeast species B. raffinosifermentans using the Xplor2 system. We increased lipid accumulation by over-expressing two native diacylglycerol acyltransferase genes, DGA1 and DGA2. Our best strain, derived from the parental strain G1212, produced 26.5 g/L lipid from 30g/L glucose in shake-flask experiments. This strain also produced citric acid like Y. lipolytica. We didn’t find significant overall elevated expression in lipid synthesis pathway for DGA1 gene when lipid production was favored on contrary to DGA2 gene. This work represents one of the first metabolic engineering of B. adeninivorans for lipid production

Full textIntegrated analysis of genomic and pharmacological data to better predict the response to targeted therapiesThe use of targeted therapies in the context of cancer personalized medicine has shown great improvement of patients’ treatment in different cancer types. However, while the therapeutic decision is based on a single molecular alteration (for example a mutation or a gene copy number change), tumors will show different degrees of response. In this thesis, we demonstrate that a therapeutic decision based on a unique alteration is not optimal and we propose a mathematical model integrating genomic and pharmacological data to identify new single predictive biomarkers as well as combinations of biomarkers of therapy response. The model was trained using two public large-scale cell line data sets (the Genomics of Drug Sensitivity in Cancer, GDSC and the Cancer Cell Line Encyclopedia, CCLE) and validated with cell line and clinical data. Additionally, we also developed a new method for improving the detection of somatic mutations using whole exome sequencing data and propose a new tool, cmDetect, freely available to the scientific community

Full textRalstonia solanacearum is a plant pathogenic bacterium globally distributed with a particularly broad host range. This organism is biologically diverse and is adapted to all types of soil, to planktonic lifestyle and to many plant hosts and natural reservoirs. This bacterium is a species complex and its genetic, phenotypic and host range diversity is a direct consequence of adaptation mechanisms. Phylogenetic analyses have divided this species complex into four distinct phylotypes correlating mostly with strains’ geographical origin. This thesis focuses on using phylotype II strains as an experimental model due to their adaptation to specific hosts: Moko strains pathogenic to banana, ‘Brown rot’ strains adapted to potatoes and emergent pathological variant NPB strains. Our main research topic is the understanding of host adaptation processes. In order to tackle this problematic we sequenced about ten genomes as a starting point of (i) a taxonomic revision of the species complex (ii) a comparative genomic analysis and (iii) an in planta transcriptomic analysis. Together, these complementary approaches allow a more systemic view of this organism’s genetic and phenotypic complexity

Full textIn oncology, a new paradigm tries to impose itself ; analyzing patient’s tumors, and identifying molecular alterations matching with targeted therapies to guide a personalized therapeutic orientation. Here, We discuss the molecular alterations possibly relevant for a therapeutic orientation, as well as the methods used for their identification : among the alterations of interest, copy number variations are widely used, and we more specifically focus on comparative genomic hybridization (aCGH). We show, using well characterized cell lines, that identification of CNV is not trivial. In particular, the choice for centralizing profiles can be critical, and different strategies for adjusting profiles on a theoretical 2n baseline can lead to erroneous interpretations. Next, we show, using tumor samples, that a major consequence is to include, or miss, targetable alterations within the decision procedure. This work lead us to develop a comprehensive workflow, dedicated to aCGH analysis. This workflow supports the major aCGH platforms, ensure a full traceability of the entire process and provides interactive visualization tools to assist the interpretation. This workflow, called rCGH, has been implemented as a R package, and is available on Bioconductor. The interactive visualization tools are available on line, and are ready to be installed on any institutional server

Full textTranscription is the first step of gene expression. In eukaryotes, messenger RNA (mRNA) transcription is a highly regulated process. Transcription begins with the binding of a specific transcription factor on a DNA regulatory sequence. This enable the recruitment of co-activators, followed by general transcription factors (GTFs) and RNA polymerase II (Pol II) to form preinitiation complex (PIC). Mediator is a co-activator complex which is essential in this process. In yeast Saccharomyces cerevisiae, Mediator is composed of 25 subunits, among which 10 are essential for cell viability, organized into four distinct modules. The main role of this complex is to transmit regulatory signal to PIC components. Although Mediator has been the subject of a large numbers of studies, its complexity prevents the detailed understanding of how it acts in vivo. During my PhD, I focused my work on the study of the two essential subunits Med7 and Med10. Both of these subunits belong to the middle module, poorly studied so far. We obtained a collection of temperature-sensitive mutants of Med7 and Med10 in yeast S. cerevisiae. We used different molecular biology and functional genomics to characterize these mutants. The work on Med10 subunit enabled us to highlight in vivo a functional link between Mediator and TFIIB, one of the GTFs. Notably, we have shown a new contact between Med14 subunit and TFIIB. Our ChIP-seq analysis shows that Mediator middle module, and in particular Med10 subunits, is crucial for PIC assembly genome-wide. These data also permit us to show that Mediator influence PIC formation in relation to promoter architecture. Taken together, these results indicates that Mediator in crucial to orchestrate the incorporation of the different proteins into the PIC. This work permit us to improve our understanding of how functional interplay between Mediator, TFIIB, other GTFs, and the promoter architecture leads to gene-specific transcription

Full textGene expression data is recognized as high-dimensional data that needs specific statisticaltools for its analysis. But in the context of vaccine trials, other measures, such asflow-cytometry measurements are also high-dimensional. In addition, such measurementsare often repeated over time. This work is built on the idea that using the maximum ofavailable information, by modeling prior knowledge and integrating all data at hand, willimprove the inference and the interpretation of biological results from high-dimensionaldata. First, we present an original methodological development, Time-course Gene SetAnalysis (TcGSA), for the analysis of longitudinal gene expression data, taking into accountprior biological knowledge in the form of predefined gene sets. Second, we describetwo integrative analyses of two different vaccine studies. The first study reveals lowerexpression of inflammatory pathways consistently associated with lower viral rebound followinga HIV therapeutic vaccine. The second study highlights the role of a testosteronemediated group of genes linked to lipid metabolism in sex differences in immunologicalresponse to a flu vaccine. Finally, we introduce a new model-based clustering approach forthe automated treatment of cell populations from flow-cytometry data, namely a Dirichletprocess mixture of skew t-distributions, with a sequential posterior approximation strategyfor dealing with repeated measurements. Hence, the automatic recognition of thecell populations could allow a practical improvement of the daily work of immunologistsas well as a better interpretation of gene expression data after taking into account thefrequency of all cell populations
