MetabolomicsGenome-scale metabolic modelling of responses to polymyxins in Pseudomonas aeruginosa
Background: Pseudomonas aeruginosa often causes multidrug-resistant infections in immunocompromised patients and polymyxins are often used as the last-line therapy. Alarmingly, resistance to polymyxins has been increasingly reported worldwide recently. To rescue this last-resort class of antibiotics...

MetabolomicsJ-Resolved 1H NMR 1D-Projections for Large-Scale Metabolic Phenotyping Studies: Application to Blood Plasma Analysis
1H nuclear magnetic resonance (NMR) spectroscopy-based metabolic phenotyping is now widely used for large-scale epidemiological applications. To minimize signal overlap present in 1D 1H NMR spectra, we have investigated the use of 2D J-resolved (JRES) 1H NMR spectroscopy for large-scale phenotyping ...

MetabolomicsMicrobial community-scale metabolic modelling predicts personalized short-chain fatty acid production profiles in the human gut
Microbially derived short-chain fatty acids (SCFAs) in the human gut are tightly coupled to host metabolism, immune regulation and integrity of the intestinal epithelium. However, the production of SCFAs can vary widely between individuals consuming the same diet, with lower levels often associated ...

MetabolomicsCharacterization of the Human Exposome by a Comprehensive and Quantitative Large-Scale Multianalyte Metabolomics Platform
The exposome, defined as the cumulative measure of external exposures and associated biological responses throughout the lifespan, has emerged in recent years as a cornerstone in biomedical sciences. Metabolomics stands out here as one of the most powerful tools for investigating the interplay betwe...

MetabolomicsGenome-scale study reveals reduced metabolic adaptability in patients with non-alcoholic fatty liver disease
Non-alcoholic fatty liver disease (NAFLD) is a major risk factor leading to chronic liver disease and type 2 diabetes. Here we chart liver metabolic activity and functionality in NAFLD by integrating global transcriptomic data, from human liver biopsies, and metabolic flux data, measured across the ...

MetabolomicsTroubleshooting in Large-Scale LC-ToF-MS Metabolomics Analysis: Solving Complex Issues in Big Cohorts
Metabolomics, understood as the science that manages the study of compounds from the metabolism, is an essential tool for deciphering metabolic changes in disease. The experiments rely on the use of high-throughput analytical techniques such as liquid chromatography coupled to mass spectrometry (LC-...

MetabolomicshRUV: Hierarchical approach to removal of unwanted variation for large-scale metabolomics data
Liquid chromatography-mass spectrometry-based metabolomics studies are increasingly applied to large population cohorts, which run for several weeks or even years in data acquisition. This inevitably introduces unwanted intra- and inter-batch variations over time that can overshadow true biological ...

MetabolomicsGeneration of a chromosome-scale genome assembly of the insect-repellent terpenoid-producing Lamiaceae species, Callicarpa americana

BACKGROUND: Plants exhibit wide chemical diversity due to the production of specialized metabolites that function as pollinator attractants, defensive compounds, and signaling molecules. Lamiaceae (mints) are known for their chemodiversity and have been cultivated for use as culi...

MetabolomicsA large-scale metabolomics study to harness chemical diversity and explore biochemical mechanisms in ryegrass (UPLC-MS HILIC POS assay)
Perennial ryegrass (Lolium perenne) is integral to temperate pastoral agriculture, which contributes most of the milk and meat production worldwide. Chemical profiles and diversity of ryegrass offer several opportunities to harness specific traits and elucidate underlying biological mechanism...

MetabolomicsNon-targeted in vitro metabolomics for proteome-scale identification of novel enzymes in Escherichia coli
Many yet undiscovered enzymes still limit our understanding of metabolism. Here, we develop a high-throughput mass spectrometry approach to comprehensively profile proteome-scale protein collections for in vitro enzymatic activity. Overexpressed or purified proteins are incubated in a supplemented m...
