A small step into Galaxy, a faster pace for metabolomics. Galaxy and the metabolomics analysis Universe

National audienceFacing the emergence of new technologies in the field of metabolomics, treatment solutions adopted so far (XCMS, R scripts, etc.) clearly show their limits. Bottlenecks affect unified access to core applications as well as computing infrastructure and storage. In the context of collaboration between metabolomics and bioinformatics platforms, we have developed a full pipeline using Galaxy framework for data analysis. This modular and extensible workflow includes existing components (XCMS functions, etc.) but also a whole suite of complementary statistical tools. This implementation is accessible through a web interface, which guarantees the parameters completeness. The advanced features of Galaxy have made possible the integration of components from different sources and of different types. Finally, an extensible environment is offered to the metabolomics community, and enables preconfigured workflows sharing for new users, but also experts in the field.Face à l’arrivée de nouvelles technologies dans le domaine de la métabolomique, les solutions de traitements adoptées jusqu’à maintenant (XCMS, scripts R, etc.) montrent clairement des limites. Les verrous concernent aussi bien l’accessibilité unifiée aux applications métiers que les problèmes d’infrastructure de calcul ou de stockage. Dans le cadre d’une collaboration entre les plateformes INRA/PFEM et CNRS/ABiMS-METABOMER, nous avons développé sous Galaxy un pipeline complet d’analyse. Ce workflow modulaire et extensible, inclut des composants existant (fonctions XCMS, etc.) mais aussi toute une suite d’outils statistiques complémentaires. Cette implémentation, accessible au travers d’une interface web, garantie l’exhaustivité des paramètres. Les fonctionnalités avancées de Galaxy ont permis l’intégration de composants provenant de différentes sources et de nature différente. Au final, un premier environnement est proposé à la communauté métabolomique, et permet le partage de workflows préconfigurés à destination d’utilisateurs novices, mais aussi d’experts du domaine

Dietary aquaculture by-product hydrolysates: impact on the transcriptomic response of the intestinal mucosa of European seabass (Dicentrarchus labrax) fed low fish meal diets

International audienceBackground: Aquaculture production is expected to double by 2030, and demands for aquafeeds and raw materials are expected to increase accordingly. Sustainable growth of aquaculture will require the development of highly nutritive and functional raw materials to efficiently replace fish meal. Enzymatic hydrolysis of marine and aquaculture raw materials could bring new functionalities to finished products. The aim of this study was to determine the zootechnical and transcriptomic performances of protein hydrolysates of different origins (tilapia, shrimp, and a combination of the two) in European seabass (Dicentrarchux labrax) fed a low fish meal diet (5%), for 65 days.Results: Results were compared to a positive control fed with 20% of fish meal. Growth performances, anterior intestine histological organization and transcriptomic responses were monitored and analyzed. Dietary inclusion of protein hydrolysates in the low fish meal diet restored similar growth performances to those of the positive control. Inclusion of dietary shrimp hydrolysate resulted in larger villi and more goblet cells, even better than the positive control. Transcriptomic analysis of the anterior intestine showed that dietary hydrolysate inclusion restored a pattern of intestinal gene expression very close to the pattern of the positive control. However, as compared to the low fish meal diet and depending on their origin, the different hydrolysates did not modulate metabolic pathways in the same way. Dietary shrimp hydrolysate inclusion modulated more metabolic pathways related to immunity, while nutritional metabolism was more impacted by dietary tilapia hydrolysate. Interestingly, the combination of the two hydrolysates enhanced the benefits of hydrolysate inclusion in diets: more genes and metabolic pathways were regulated by the combined hydrolysates than by each hydrolysate tested independently.Conclusions: Protein hydrolysates manufactured from aquaculture by-products are promising candidates to help replace fish meal in aquaculture feeds without disrupting animal metabolism and performances

ABRomics: An integrated multi-omics platform for antibiotic resistance research and public health

International audienceAntibiotic resistance (ABR) is a major public health issue prioritized for mitigation by international institutions. Multidrug resistant bacteria (MDRB) and Antibiotic Resistance Genes (ARGs) carried by mobile genetic elements spread between the human, animal, and environmental sectors. Whole Genome Sequencing (WGS) is used for molecular typing purposes at the highest resolution. It provides identification of ARGs and their genetic supports as well as mutations leading to a decrease in antibiotic susceptibility. Epidemiological and WGS data are used for tracking MDRB in hospital outbreaks but also across the animal and environmental sectors. Sharing and interoperability of high-quality data (sequence and metadata) are key requirements for addressing the spatio-temporal dissemination of MDRB. To this aim, the French Priority Plan on ABR has funded the development of an online, open platform dedicated to antibiotic resistance.We are establishing a repository of structured, interoperable, standardized, and well-annotated multi-omics data with tailored mathematical and bioinformatics tools to answer generic and specific research questions related to ABR. The ABRomics platform includes standardized pipelines to run ABR analyses of WGS from pathogenic strains supported with integrated databases (ARG, sequence types [ST], virulence factors [VF]). Uploading data, launching pipelines, viewing and cross-referencing enriched results will be achieved through easy-to-use web interfaces. ABRomics ß-version integrating the ABR detection genomic pipeline and other markers such as ST, and VF will be available to the consortium in summer 2023 and to the whole microbial research community by the end of 2023. Core-genome multi-locus sequence typing, relationships between strains and metagenomics pipelines will next be made available
