MetabolomicsGC-MS Based Plasma Metabolomics for Identification of Candidate Biomarkers for Hepatocellular Carcinoma in Egyptian Cohort
This study evaluates changes in metabolite levels in hepatocellular carcinoma (HCC) cases vs. patients with liver cirrhosis by analysis of human blood plasma using gas chromatography coupled with mass spectrometry (GC-MS). Untargeted metabolomic analysis of plasma samples from participants recruited...

MetabolomicsSteady state isotope tracing in C. elegans (GC-MS analyses)

The metabolic network, composed of thousands of metabolic reactions, is essential for any organism. Despite its importance, a systems level understanding of how metabolic network is wired by reactions that carry flux in unperturbed condition and rewired by transcriptionally activating or repressi...

MetabolomicsGC-MS based targeted metabolic profiling identifies changes in the wheat metabolome following deoxynivalenol treatment
Fusarium graminearum and related species commonly infest grains causing the devastating plant disease Fusarium head blight (FHB) and the formation of trichothecene mycotoxins. The most relevant toxin is deoxynivalenol (DON), which acts as a virulence factor of the pathogen. FHB is difficult to contr...

MetabolomicsA novel targeted/untargeted GC-Orbitrap metabolomics methodology applied to Candida albicans and Staphylococcus aureus biofilms

INTRODUCTION: Combined infections from Candida albicans and Staphylococcus aureus are a leading cause of death in the developed world. Evidence suggests that Candida enhances the virulence of Staphylococcus - hyphae penetrate through tissue bar...

MetabolomicsEffects of Centella asiatica extract on antioxidant status and liver metabolome of rotenone-treated rats using GC-MS
The standardized extract of Centella asiatica (ECa233) contains >80% triterpenoids with a ratio of madecassoside to asiaticoside of 1.5(±0.5):1. Hepatoprotective effect of ECa233 has not yet been reported. The aim of this study was to examine the effect of ECa233 on liver metabolome of rotenone-trea...

MetabolomicsCharacterization of Cabernet Sauvignon Wines by Untargeted HS-SPME GC-QTOF-MS
Untargeted metabolomics approaches are emerging as powerful tools for the quality evaluation and authenticity of food and beverages and have been applied to wine science. However, most fail to report the method validation, quality assurance and/or quality control applied, as well as the assessment t...

MetabolomicsComparison of singlequad and Orbitrap mass analyzer coupled to gas chromatography reveals potential of high resolution GC MS for untargeted metabolomics

The development of improved spectrometers and supporting computational tools is expected to eventually enable the rapid annotation of whole metabolomes. However, rarely are novel mass spectrometers directly compared to the previously used ones in the field of metabolomics, thus preventing researc...

MetabolomicsFlow cytometry has a significant impact on the cellular metabolome (GC-MS assay)
The characterization of specialized cell subpopulations in a heterogeneous tissue is essential for understanding organ function in health and disease. A popular method of cell isolation is fluorescence-activated cell sorting (FACS) based on probes that bind surface or intracellular markers. In this ...

MetabolomicsA Metabolic Profiling Strategy for the Dissection of Plant Defense against Fungal Pathogens (GC-MS assay)
Here we present a metabolic profiling strategy employing direct infusion Orbitrap mass spectrometry (MS) and gas chromatography-mass spectrometry (GC/MS) for the monitoring of soybean's (Glycine max L.) global metabolism regulation in response to Rhizoctonia solani infection in a time-course. Key el...

MetabolomicsAssessment of automated trimethylsilyl derivatisation protocols for GC-MS-based untargeted metabolomic analysis of urine
GC-MS is a commonly used metabolomic platform for the analysis of urine. A key step in the preparation of samples for GC-MS is derivatisation, in particular, methoximation and trimethylsilylation. This paper presents an assessment of automated derivatisation protocols for GC-MS-based untargeted meta...
