MetabolomicsgeoRge: A Computational Tool To Detect the Presence of Stable Isotope Labeling in LC/MS-Based Untargeted Metabolomics
Studying the flow of chemical moieties through the complex set of metabolic reactions that happen in the cell is essential to understanding the alterations in homeostasis that occur in disease. Recently, LC/MS-based untargeted metabolomics and isotopically labeled metabolites have been used to facil...

MetabolomicsStable Isotope–Assisted Plant Metabolomics: Combination of Global and Tracer-Based Labeling for Enhanced Untargeted Profiling and Compound Annotation
Untargeted approaches and thus biological interpretation of metabolomics results are still hampered by the reliable assignment of the global metabolome as well as classification and (putative) identification of metabolites. In this work we present an liquid chromatography-mass spectrometry (LC-MS)-b...

MetabolomicsMatrix Effect on Chemical Isotope Labeling and Its Implication in Metabolomic Sample Preparation for Quantitative Metabolomics
Matrix effect from various constituents in biological samples can reduce the accuracy of quantitative metabolomics. Differential chemical isotope labeling liquid chromatography mass spectrometry (CIL LC-MS) can overcome the matrix effect on MS detection based on measuring the intensity ratios of met...

MetabolomicsGlobal Stable-isotope Tracing Metabolomics Reveals System-wide Metabolic Alternations in Aging Drosophila

System-wide metabolic homeostasis is crucial for maintaining physiological functions of living organisms. Stable-isotope tracing metabolomics allows to unravel metabolic activity quantitatively by measuring the isotopically labeled metabolites, but has been largely restricted by coverage. Yet, de...

MetabolomicsStable isotope labelling of Toxoplasma gondii under iron and copper restriction

Toxoplasma uses metal nutrients like iron and copper for vital functions in their energy metabolism. Here, we have used stable isotope labelling to track the incorporation of glucose and glutamine into metabolic pathways, primarily focusing on central carbon metabolism, when these metals are disr...

MetabolomicsUntargeted extraction of metabolites 13C labeling profiles from time course labeling switch experiment
Dynamic isotope labeling data provide crucial information about the operation of metabolic pathways, and are commonly generated via liquid chromatography mass spectrometry (LC-MS). Metabolome-wide analysis is challenging as it requires grouping of metabolite features over different samples. We devel...

MetabolomicsPositional Enrichment by Proton Analysis (PEPA): a One-Dimensional 1H-NMR Approach for 13C Stable Isotope Tracer Studies in Metabolomics
A novel metabolomics approach for NMR-based stable isotope tracer studies called PEPA is presented, and its performance validated using human cancer cells. PEPA detects the position of carbon label in isotopically enriched metabolites and quantifies fractional enrichment by indirect determination of...
