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...

MetabolomicsIsotopomer analysis of MCF-7 breast cancer cell line incubated with 13C labelled glucose (NMR assay)
MS and NMR are two of the most powerful spectroscopic techniques used in the field of fluxomics, to analyze the flux distributions in cellular metabolomic pathways. Both of them possess pros and cons, such as, MS being the most sensitive and low-cost technique, while needs extensive sample processin...

MetabolomicsGlobal 13C tracing and metabolic flux analysis of intact human liver tissue ex vivo
Liver metabolism is central to human physiology and influences the pathogenesis of common metabolic diseases. Yet, our understanding of human liver metabolism remains incomplete, with much of current knowledge based on animal or cell culture models that do not fully recapitulate human physiology. He...

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...

Metabolomics13C-glucose tracing analysis of IFN-treated A549 cells expressing wild-type SARS-CoV-2 Nsp3-4 or a deISGylation-defective Nsp3-4 mutant protein

Interferon (IFN)-stimulated gene 15 (ISG15) regulates diverse cellular processes, including antiviral immunity, through its conjugation to target proteins (ISGylation). Increasing evidence suggests that ISGylation can also reshape cellular metabolism; however, how viruses counteract ISGylation-me...

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...

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...
