MetabolomicsHomeostasis of the biosynthetic E. coli metabolome
Metabolite concentrations vary across conditions and such metabolome changes are relevant for metabolic and gene regulation. Here, we used LC-MS/MS to explore metabolite concentration changes in Escherichia coli. We measured 101 primary metabolites in 19 experimental conditions that include v...

MetabolomicsSystematic identification of metabolites controlling gene expression in E. coli
Metabolism controls gene expression through allosteric interactions between metabolites and transcription factors. These interactions are usually measured with in vitro assays, but there are no methods to identify them at a genome-scale in vivo. Here we show that dynamic transcriptome and metabolome...

MetabolomicsExploring the Glucose Fluxotype of the E. coli y-ome Using High-Resolution Fluxomics
We have developed a robust workflow to measure high-resolution fluxotypes (metabolic flux phenotypes) for large strain libraries under fully controlled growth conditions. This was achieved by optimizing and automating the whole high-throughput fluxomics process and integrating all relevant software ...

MetabolomicsMetabolomic analysis of riboswitch containing E. coli recombinant expression system
In this study we have employed metabolomics approaches to understand the metabolic effects of producing enhanced green fluorescent protein (eGFP) as a recombinant protein in Escherichia coli cells. This metabolic burden analysis was performed against a number of recombinant expression systems and co...

MetabolomicsImproving the Screening Analysis of Pesticide Metabolites in Human Biomonitoring by Combining High-Throughput In Vitro Incubation and Automated LC-HRMS Data Processing
There is a current need to monitor human exposure to a large number of pesticides and other chemicals of emerging concern (CECs). This requires screening analysis with high confidence for these compounds and their metabolites in complex matrices, which is hampered by the fact that no reference stand...

MetabolomicsUnexpected similarities between the Schizosaccharomyces and human blood metabolomes, and novel human metabolites (Blood fraction)
Metabolomics, a new branch of chemical biology, provides compositional and quantitative information about the state of organism or cell at the levels of metabolite constituents. We here report non-targeted metabolome of human blood that is made up of plasma and red blood cells (RBCs), using liquid-c...

MetabolomicsSelective galactose culture condition reveals distinct metabolic signatures in pyruvate dehydrogenase and complex I deficient human skin fibroblasts

INTRODUCTION: A decline in mitochondrial function represents a key factor of a large number of inborn errors of metabolism, which lead to an extremely heterogeneous group of disorders.

OBJECTIVES: To gain insight into the biochemical consequences of mitocho...

MetabolomicsMapping human microbiome drug metabolism by gut bacteria and their genes

Individuals vary widely in their drug responses, which can be dangerous and expensive due to treatment delays and adverse effects. Growing evidence implicates the gut microbiome in this variability, however the molecular mechanisms remain largely unknown. We measured the ability of 76 diverse hum...

MetabolomicsUntargeted metabolomic analysis of human milk from healthy mothers reveals drivers of metabolite variability.
Understanding the human milk metabolome can help inform infant nutrition and health. Untargeted metabolomics was used to study breast milk from 31 healthy participants to assess the shared metabolites in milk from participants with various backgrounds and understand how different demographic, health...

MetabolomicsProteomic and metabolomic profiling of extracellular vesicles produced by human gut archaea

Gastrointestinal bacteria interact with the host and each other through various mechanisms, including the production of extracellular vesicles (EVs). However, the composition and potential roles of EVs released by gut archaea are poorly understood. Here, we study EVs produced by four strains of h...
