Full textThis thesis presents three studies related to the phenomenon related to DNA hybridization onto capture probes attached to solid support. The work was carried out in the context of infectious diseases detection, but the conclusions are of interest to any test based on the recognition of genetic material by solid support immobilized capture probes. DNA hybridization in aqueous phase is well characterised, however several parameters and phenomena related to hybridization onto solid supports are still to be determined. One of these parameters is the influence of the complementary strand in relation with the length of the solvent-exposed immobilized target strand. To better understand this phenomenon, we established a method to specifically digest the complementary DNA strands to simplify hybridization onto solid support. The presence of a molecule favorising digestion on the complementary strand and a blocking molecule on the target strand enabled selective digestion of the complementary strand using Lambda exonuclease in PCR buffer. Hybridization of single-stranded target DNA generated this way resulted in significantly higher fluorescence signals than those obtained with double stranded hybridization. Afterwards, observation of real-time hybridization of single-stranded amplicons and double-stranded amplicons to capture probes fixed onto solid support allowed for a better understanding of the competition phenomena between the complementary strand and the capture probe. Finally, the knowledge gained with the first two studies was used to invent a technology taking advantage of the competition between the complementary strand and the capture probe and exonuclease activity to perform single vessel and single buffer PCR amplification and microarray hybridization. The combination of these techniques will simplify devices and require fewer reagents storage and handling, facilitating production of automated diagnostic tests at lower costs. The works of this thesis have expended our understanding of the phenomena associated with hybridization onto a solid support and also resulted in the creation of a new technology covered by a patent application. The logical progression of this work is to further develop and optimize this technology by integrating it into a microfluidic device and an instrument compatible with the detection of microarrays to increase the multiplexing capabilities of molecular diagnostics.

Full textIdentification of organisms are still often based on phenotypical characters. However, this type of identification is approximative and difficult for micro-organisms. DNA micro-arrays appear to be a solution for a fast and reliable identification of a large number of species. However, this technique is relatively recent and it is still necessary to improve it, in particular at the conceptual level. Within this framework, the objective of my thesis was to implement new means for chip design. This work was completed through two projects: The project "Aquachip" aimed in designing a DNA array for the identification of pathogenic bacteria present in bathing and drinking water. The project grouped several european laboratories that had to exchange a large amount of data. Such significant flow of information is often badly managed and slows down research. Consequently, we developed a dynamic numerical platform, the "E-dashboard" (MySQL, PHP), allowing all partners to manage data. This tool made it possible on the one hand to follow the progress of the various steps of the project and on the other hand to optimize exchanges between partners. In a second project, "Mycochip", the objective was to develop a DNA array to identify ectomychorizian fungi. ITS sequences (Internal Transcribed Spacers) from a very divergent area located between ribosomal RNA genes are used for this study. The project initially required the development of a tool to retrieve sequences, " EmblEx " (Perl, MySQL), which is more specific and powerful than Entrez, SRS or ACNUC. Then, the ambiguous taxonomy of fungi led us to conceive a new method of classification through partitioning without alignment. Biological experiments showed that reliable probes could be determined by this approach

Full textThe emergence of biotechnology, such as DNA chips, has acquired huge amounts of data in a cell at a given moment and under certain conditions. They are used in order to understand a disease whose origin is a genomic abnormality disrupting the natural development between growth, division and cell death. Using this biotechnology, the aim is to identify the genes involved in disease studied. But each chip gives information on more than 19,000 genes then it is difficult to use and to analyse the results. Methods of Data mining are used in order to find interesting correlations from large database. Initially proposed to address questions about the behavior of customers of a supermarket, these methods are now used and adapted in various fields of applications ranging marketing to health. In this study, we propose new methods in order to help biologists to deduce new knowledge from data obtained by DNA microarray analysis. Specifically, we propose to identify genes frequently ordered by their expressions and we study the contribution of such information as the new study material for biologists

Full textThis thesis deals with statistical questions raised by the analysis of high-dimensional genomic data for cancer research. In the first part, we study asymptotic properties of multiple testing procedures that aim at controlling the False Discovery Rate (FDR), that is, the expected False Discovery Proportion (FDP) among rejected hypotheses. We develop a versatile formalism to calculate the asymptotic distribution of the FDP an the associated regularity conditions, for a wide range of multiple testing procedures, and compare their asymptotic power. We then study in terms of FDR control connections between intrinsic bounds between three multiple testing problems: detection, estimation and selection. In particular, we connect convergence rates in the estimation problem to the regularity of the p-value distribution near 1. In the second part, we develop statistical methods to study DNA microarrays for cancer research. We propose a microarray normalization method that removes spatial biases while preserving the true biological signal; it combines robust regression with a mixture model with spatial constraints. Then we develop a method to infer gene regulations from gene expression data, which is based on learning and multiple testing theories. Finally, we build a genomic score to predict, for a patient treated for a breast tumor, whether or not a second cancer is a true recurrence of the first cancer

Full textCDNA microarrays are a method for measuring simultaneously the expression levels of thousands of genes. In this work, we consider statistical methods for gene expression data analysis. After the normalization step, two problems can be considered: first the determination of a statistically significant change in gene expression between two experimental conditions and second the analysis of gene expression profiles. Data variability is one of the main difficulties that led us to develop specific methods. To detect differentially expressed genes, we describe the need for experimental replication to robustify the analysis. First, analysis of variance is investigated to determine which factors of variability are relevant. An ongoing work considers more complex approach that introduces different variance components. In this model, gene expression levels are represented by linear mixed models. In a next step, in order to account for data variability in gene expression profiles clustering, we propose to properly exploit the data repetitions. Repeated data clustering is an approach to isolate error measurements from covariable random effects. Our approach is based on mixed model mixture. For each class, statistic units can be characterized by different mixed models and several mixture models are considered. Within a probabilistic framework, the problem of selecting a particular mixed model mixture is solved minimizing information criteria
