Full textProteomic analysis consists of studying all the proteins expressed by a given biological system, at a given time and under given conditions. Recent technological advances in mass spectrometry and liquid chromatography make it possible to envisage large-scale and high-throughput proteomic studies.This thesis work focuses on developing statistical methodologies for the analysis of quantitative proteomics data and thus presents three main contributions. The first part proposes to use monotone spline regression models to estimate the amounts of all peptides detected in a sample using internal standards labelled for a subset of targeted peptides. The second part presents a strategy to account for the uncertainty induced by the multiple imputation process in the differential analysis, also implemented in the mi4p R package. Finally, the third part proposes a Bayesian framework for differential analysis, making it notably possible to consider the correlations between the intensities of peptides

La partie suivante détaille la mise au point d'un tel algorithme pour la sélection de biomarqueurs en spectrométrie de masse et l'alignement de gels d'électrophorèse 2D. Cette partie met en évidence la difficulté de construction du critère à optimiser. La dernière partie aborde des résultats théoriques. La convergence des algorithmes génétiques avec élitisme est démontrée dans le cas non homogène et de mutations dirigées. Nous avons ensuite construit un critère de convergence alliant fondements théoriques et applicabilité, basé sur les occurrences de la solution localement optimale. Enfin, l'efficacité de l'introduction d'événements catastrophiques dans la résolution pratique de certains problèmes de convergence est montrée.

Full textDiscovery, confirmation and verification of candidate biomarkers for multiple sclerosis diagnosis and prognosis in cerebrospinal fluid.Multiple sclerosis (MS) is an inflammatory disease of the central nervous system. Most often the disease initiates by a first demyelinating event called clinically isolated syndrome (CIS), followed by remission periods and relapses occurring at irregular intervals. Clinical symptoms and MRI are used for diagnosis, but clinicians lack tools to predict the rate of disease progression. This study aims at identifying biomarkers that predict the delay of conversion to MS after a CIS. We compared the cerebrospinal fluid (CSF) proteome from MS patients and symptomatic controls and the CSF from CIS patients with rapid conversion to MS (<1 year) and CIS patients with slow conversion to MS (>2 years). For the discovery step, human CSF samples (n=40) depleted of the 20 major plasma proteins were digested using a modified filter-assisted sample preparation (FASP) and analysed by high-resolution mass spectrometry using isobaric mass tag labelling or label-free quantification procedures. Proteins upregulated in CSF from MS patients included two proteins involved in tissue remodeling, namely chitinase-3-like protein-1 (CHI3L1) and chitinase-3-like protein-2 (CHI3L2). Their increased level in CSF of MS patients was confirmed by ELISA in a new cohort comprising CIS and MS patients (n=123) at different disease stages. Moreover, CHI3L1 levels in CSF and serum from CIS patients discriminated patients with rapid conversion to MS (< one year) from those with slower conversion.We also implemented a PRM method (peptide selection, dilution optimization of heavy isotope labeled non-purified peptides, reproducibility evaluation and method validation) to qualify a larger set of candidate biomarkers (226 peptides corresponding to 87 proteins) in a cohort different from the one used for the discovery step (n=60), including CSF from controls and MS patients at different disease stages. Finally, to further verify the 11 candidate biomarkers that passed this qualification step, we monitored 16 peptides in a new PRM assay, using shorter gradient and high-purity heavy isotope labeled peptides. This new PRM analysis was performed on a larger cohort (n=189) that included CSF of patients with other inflammatory and non-inflammatory neurological disorders in addition to control and MS patients. These analyses identified seven robust candidate biomarkers, which might help to discriminate patients suffering from MS or other neurological disorders

Full textProteomics consists in the characterization of all the proteins expressed in a physiological state and at a given time (the proteome). Today, proteomics tends to bring quantitative information. However, in order to generate reliable, sensitive and robust data, whatever the biological question, methodological improvements need to be done. The aim of this PhD thesis was to apply and adapt quantitative proteomics strategies to specific biological issues as there is no universal quantifying method. This PhD thesis contributed to bringing original results concerning the study of metabolic disorders. It has also contributed to setting-up a targeted approach in order to quantify the level of reproductive effort of Leatherback Turtles. Finally, this PhD thesis also contributed, through the consortium NOTOX (EU), to the evaluation of physiological answers of hepatic cell lines exposed to valproic acid. These data will be used in order to generate hepatotoxicity prediction algorithms

Full textProteomics analysis corresponds to the qualitative and quantitative analysis of all proteins expressed in a cell or tissue under given conditions (proteome). Instrumental progresses in mass spectrometry and bioinformatics advances in recent years have allowed its establishment in life sciences. Diverse proteomics strategies thus allow identification and quantification of hundreds/thousands of proteins in complex samples, which classically allows physiopathological states to be characterized. However, proteomics is only emerging in the evolutionary biology field. This field aims at understanding the determinants of the diversity of organisms present on Earth and their “functioning”, including their adaptations to certain environmental constraints.The objective of this thesis was to study, from the organ to the eco-system, the proteomic variations induced by environmental changes, while adapting the different steps of the analysis to each type of sample, each organism, from sample preparation to data analysis. Through the introduction of an original quantitative de novo sequencing strategy, we studied the role of brown adipose tissue against obesity in a non-sequenced species: the vole. Other particular traits were explored, such as the reversible obesity of the grey mouse lemur or the interactions between sociality and longevity in the ant. The considered software solutions did not allow to robustly quantify peptides identified by de novo sequencing from fractionated samples, we thus determined that prefractionation allows for better proteome coverage. On the other hand, without prefractionation, de novo sequencing produces an undeniable gain. Finally, by studying the metaproteome of alpine soil biotic communities, we have highlighted the advantage of combining proteomics and genomics, in order to establish the most appropriate protein database and to “validate” proteomics data

Full textTherapeutics targeting HER2 protein or its pathway considerably improved the prognosis of HER2-positive BC. The actual approaches to evaluate HER2 expression, immunohistochemistry (IHC) and FISH (fluorescent in situ hybridization), are labor-intensive and low-throughput, and present discrepancies between them. Therefore, there is a real need to develop other strategies to rationalize the use of targeted therapeutics. Parallel Reaction Monitoring (PRM) is a mass spectrometry-based approach for targeted proteomics able to detect and quantify numerous proteins with high-throughput allowing to follow mutated or activated status of targeted proteins. PRM could be a way to rationalize the use of targeted therapeutics to go through a more « personalized » medicine. The objective was to detect and quantify proteins implicated in HER2 pathway (EGFR, HER2, HER3, PTEN), phosphorylated peptides of HER2 and their response under treatment. We first selected proteotypic peptides of each protein and protein assays were generated. We detected and quantified proteotypic peptides of proteins of interest 1/on 17 breast cell lines on control condition and under treatment (trastuzumab or lapatinib). 2/ on more complex samples including patients-derived xenografts and human breast cancers. We correlated our data to gold standards western blot and IHC and to transcriptomic signatures previously validated. In the future, this approach could envision a picture of the expression and activation of proteins implicated in HER2-pathway. However, our strategy could be improved by more efficient mass spectrometers and the use of formalin-fixed paraffin-embedded samples to be used in clinical practice

Full textThe high intrinsic complexity of biological samples, the technical variability and the dependency of Bottom-up Proteomics to consensus protein sequence databases handicap the comprehensive analysis of an entire Proteome. My doctoral work was focused on method development in quantitative Proteomics and Proteogenomics in order to achieve a better proteome characterization. First, I focused on the development of global and targeted quantitative methods. The introduction and development of standard samples to assess the performances at any level of the analytical workflow is also described. These methods were applied to answer different biological questions. My PhD also focused on Proteogenomic method development. A high throughput N-terminomic analysis approach was developed and applied to the analysis of the human mitochondria. Finally, this manuscript presents a personalized multi-omics profiling strategy to improve the proteome analysis with the use of personalized databases
