Full textThe goal of this thesis is to study how the mammal cell adjusts its metabolism to the steps of the cell cycle. The cell cycle is the series of events leading a cell to divide itself. The purpose of the metabolism is to supply the cell with all the elements and the energy it needs to work. In particular, at every step of the cell cycle, the cell needs different elements to properly divide itself. So, it is crucial for the cell to coordinate the metabolism and the cell cycle and in particular to control what the metabolism produces through the cell cycle. To have a better understanding of the links between these two processes, we studied how a mathematical model representing the metabolism answered to different variations imposed by the cell cycle and we compared those answers to the literature. Satisfied by the results, we therefore built a hybrid model representing the evolution of the metabolism through the cell cycle. We recover in this hybrid model the main known variations of the metabolism through the cycle’s phases as well as experimental variations of the energetic and redox metabolites. Encouraged by these results, we finally disturbed our hybrid model to recover metabolic tendencies due to cancer, a set of diseases affecting both the metabolism and the cell cycle

Full textCurrent systems biology relies on high-throughput biological analysis techniques such as transcriptomics or metabolomics. However, these techniques may generate errors. By crossing results from different analysis techniques, we hope to avoid at least part of these limits. For that purpose, we started to develop a modeling platform, MPSA (Metabolic Pathways Software Analyzer). MPSA allows integrating biological data on metabolic pathways. MPSA also ensures the display of metabolic pathways graphs, the simulation of models based on ordinary differential equations systems solving and the study of network structures using elementary flux modes. We have developed several web applications allowing on the one hand to interpret biological results by using databases, and on the other hand to export these data to MPSA. The main database of this work is myKegg. It includes all human KEGG metabolic pathways and a list of synonyms for human KEGG entries. This base allows to identify metabolic pathways from a list of biological compounds and to import them in MPSA. Another database, BioNMR, has been developed to organize the data extracted from NMR spectra. Another web application named GeneProm has been developed to analyze gene promoters. A promotology protocol was developed and tested on a set of four genes coding for the four ANT (adenine nucleotide translocator) protein isoforms. Each ANT isoform has a specific expression profile and role in cell bioenergetics. The promotology study of these four genes led us to construct specific regulatory models from identified regulatory elements in their promoter sequence. Potentially co-regulated genes were deduced from these models. Then they can be exported to our MPSA platform. This whole development will be included in the project of Integrative Biology platform in the INRA Human Nutrition Unit

Full textAbstract: Residual biomass (RB) (e.g. livestock effluents, crop residues, green and urban waste) plays a key role in agriculture. The modernization of agriculture since the 19th century has profoundly transformed their metabolism, leading to soil impoverishment, pollution and loss of autonomy of farms and territories in terms of fertilization.Today, solid scientific facts prove the need for an ecologization of RB management, but the nature of this ecologization is debated. Radically different visions of what should be the biophysical basis of the functioning of our societies coexist and put our human and scientific communities in tension. This thesis aims to provide an analytical framework for a dialogue between the multiple pathways of ecologization: the metabolic networks. The study was conducted in the Drôme valley, a region well knowned for the development of organic agriculture. The cartography of production and flows of RB as well as the description of the multiple values given by farmers to the metabolism of RB allow us to think the tensions and complementarities between two contrasting paths of ecologization: the engineering path of optimization and "closing the loop" (industrial ecology) and cultivating bounds with the rest of the living through multiple values, beyond economic utilitarianism (the earthbound).This thesis draws up the perspectives of a more pragmatic path towards ecologization
Mahout, Maxime. "Logic programming tools for metabolic fluxes analysis and biological applications." Electronic Thesis or Diss., université Paris-Saclay, 2023. http://www.theses.fr/2023UPASG086.
Full textIn systems biology, metabolic pathways analysis is an essential method to study metabolism and improve the understanding of biological systems. Key concepts include Elementary Flux Modes (EFMs), describing metabolic networks in terms of minimal pathways, and Minimal Cut Sets (MCSs), representing minimal cutting sets of reactions affecting network flux. In the scope of this thesis, we developed a logic programming method for the computation of Elementary Flux Modes: aspefm. The tool is an automatic reasoning method based on Answer Set Programming (ASP), extended by linear constraints. This approach allows one to get minimal pathways when classical methods are unable to, and to directly query the network, helping with memory usage considerations. Important biological constraints of many different kinds can be integrated into the program, which we illustrated on a central metabolic model of Escherichia coli. The method is also applicable to genome-scale metabolic models, showing better performance than linear programming-based methods on enumeration of large-size solutions. The method was applied to the pathogenic bacterium Pseudomonas aeruginosa (PA) found in 80% of chronic wounds. PA uses different ecological strategies than model bacteria. PA is commonly co-isolated from wounds with another opportunistic pathogen, Staphylococcus aureus (SA), and it is hypothesized the metabolisms of the two bacteria are complementary enabling higher biomass production and increasing wound bioburden leading to poor patient outcomes. We extended our tool aspefm to the analysis of MCSs on a consortium model of these two bacteria, permitting us to retrieve exchanged metabolites involved in the recovery of growth after several intervention strategies, and leading to insights about potential therapeutic targets against the two bacteria. Furthermore, in an other context, we applied our computation method to cancer cell metabolism and tumoural stroma formation

Full textThe prenatal finding of unilateral Urinary Tract Dilatation (UTD) can be transient or represent a significant urinary flow impairment that would lead to progressive deterioration of renal function. Identifying urinary biomarkers could help to differentiate uropathy requiring surgical management from transient dilatation at an early stage.Metabolic phenotyping studies provide untargeted quantification of all detectable low molecular-weight molecules by profiling without any a priori the metabolic signatures of biological samples in connection to physiopathological events.The main objective of this study is to identify diagnosis and prognosis urinary markers for uropathy in newborns with prenatally diagnosed unilateral UTD using 1H-NMR spectroscopy combined with multivariate statistical analyses.A total of 70 newborns with unilateral UTD and 90 controls were included in this prospective study. First, the usefulness of different ultrasound grading systems in predicting the need for surgical intervention is evaluated. Then, we report the absence of significant difference between the urinary metabolic profiles of newborns with UTD and controls. In thethird part, the influence of age, weight and height on the urinary metabolic profiles of healthy newborns is highlighted for the first time, and key-metabolites responsible for this evolution are identified. Finally, we demonstrate the influence of age on the urinary metabolic profiles of children with UTD. This work allows a deeper understanding of the metabolic maturation of healthy newborns. It contributes to identify potential confounding factors for metabolomics investigations in neonatology. It represents a step toward a better comprehension of thephysiopathology of UTD

Full textReconstructing the metabolic pathways of an orgnanism is a task of major importance and several approaches have already been proposed in order to help biologists in this task but more exploratory approaches are needed. The first part of this thesis emphasis on what we call ab initio metabolic pathway reconstruction. This is the problem of finding a reaction network connceting two or more compounds relying only on a database of feasible reactions. We propose here a new formulation for this problem. Given a set of biochemical reactions together with their substrates and products, we consider the reactions as transfers of atoms between the chemical compounds and we look for sequences of reactions transferring a maximal (or preset) number of atoms between a source and a sink compound. We state this problem as the one of finding a composition of partial injections that maximises the image size. The theoretical complexity of this problem has been studied and a practical algoritm to solve it is presented. Ths second part presents a formalization of a problem concerning graphs comparison. The particular case treated in this thesis concerns the comparison of a network of reactions with the spatial organization of genes on the genome. This comparison permits to identify operons encoded metabolic pathways

Full textFatty acids (FA) represent the main substrate for ATP production in the heart. A balance between FA and carbohydrate utilization ensures that energy supply matches demand. This study was carried out glycerol (gly) implication on this balance. Used models are spontaneously beating neonatal rat cardiomyocytes in culture and rat working perfused isolated heart. Our results showed that the synthesis of phospholipids and the oxidation of gly increased proportionally to extracellular gly concentrations. Conversely, extracellular gly significantly reduced the palmitate oxidation and didn't modified glucose oxidation. At high concentration of gly, increased heart rate (reflected cardiac energetic demand) lead to increased complex lipids incorporation. These results clearly demonstrate the importance of gly in regulating the cardiac metabolic pathways and energy balance

Full textThe aim of the study has been the determination of isotope effects associated with three metabolic pathways (Embden-Meyerhof-Parnas, Entner-Doudoroff and phosphoketolase) using fermentation by yeasts and microorganisms bio-transforming glucose into ethanol and lactic acid. Initially, a study was conducted on the analytical parameters required for the analysis of carboxylic acids by 13C iq-NMR. Doubts raised in relation to the analysis of acetic led to the study being expanded to include a wider range of molecules. This section of the work is therefore composed of an assessment of the conditions for obtaining accurate measurements of 13C iq-NMR regardless of the spectrometer used. The current strategy to access the site-specific 13C measurements (δ13Ci) is dependent on the δ13Cg, obtained by IRMS, coupled with the determination by 13C iq-NMR of the molar fraction for each carbon measured. The implementation of the same methodology for 13C iq-NMR has required many factors to be taken into consideration. Establishing an analytical protocol for the implementation of an internal standard for 13C iq-NMR has required significant development, with the quantitative validation of a new 1H NMR sequence aiming to eliminate radiation damping. Thanks to the accurate methodology established, we have been able to detect the presence of relatively small intramolecular kinetic isotope effects associated with the metabolic pathways studied. Each pathway gives a characteristic isotopic signature, consistent with the formation of metabolites produced by the specific enzymatic reactions. The 13C isotope effects obtained are in agreement with the reactions that characterise each pathway
