MetabolomicsAn ancient residue metabolomics-based method to distinguish use of closely related plant species in ancient pipes

Residues from ancient artifacts can help identify which plant species were used for their psychoactive properties, providing important information regarding the deep-time co-evolutionary relationship between plants and humans. However, relying on the presence or absence of one or several biomarke...

MetabolomicsIntegrated metabolomics and transcriptome revealed the effect of fermented Lycium barbarum residue promoting Ovis aries immunity
Lycium barbarum residue contains abundant bioactive nutrients which can be used as feed supplement. This study investigated the effects of fermented and non-fermented Lycium barbarum residues (RFW and RW) on the meat quality and immunity of sheep (Ovis aries). Fifty-four Tan sheep were randomly divi...

MetabolomicsParallel single-cell metabolic analysis and extracellular vesicle profiling reveal vulnerabilities with prognostic significance in acute myeloid leukemia (Lipidomic analysis on extracellular vesicles)

Acute myeloid leukemia (AML) is an aggressive disease with a high relapse rate. In this study, we map the metabolic profile of CD34+(CD38low/-) AML cells and the extracellular vesicle signatures in circulation from AML patients at diagnosis. CD34+ AML cells display high antioxidant glutathione le...

MetabolomicsMonitoring of system conditioning after blank injections in untargeted UPLC-MS metabolomic analysis
Ultra-performance liquid chromatography - mass spectrometry (UPLC-MS) is widely used for untargeted metabolomics in biomedical research. To optimize the quality and precision of UPLC-MS metabolomic analysis, evaluation of blank samples for the elimination of background features is required. Although...

MetabolomicsUntargeted metabolomics analysis of intestinal contents in Common Carp

To elucidate the metabolic mechanisms underlying the beneficial effects of Enterococcus faecalis on host health under high-carbohydrate-high-fat (HCHF) stress, we performed an untargeted metabolomics analysis on intestinal contents of common carp (Cyprinus carpio). Fish were fed an HCHF diet with...

MetabolomicsMetabolomics-Based Analysis of Adaptive Mechanism of Eleutheronema tetradactylum to Low-Temperature Stress

Temperature is a critical environmental factor influencing fish physiology. Eleutheronema tetradactylum is an economically important warm-water species, but its response to long-term cold stress remains unclear. In this study, we exposed juvenile fish to 18 °C for 7 and 14 days and investigated h...

MetabolomicsDIAMetAlyzer allows automated false-discovery rate-controlled analysis for data-independent acquisition in metabolomics
The extraction of meaningful biological knowledge from high-throughput mass spectrometry data relies on limiting false discoveries to a manageable amount. For targeted approaches in metabolomics a main challenge is the detection of false positive metabolic features in the low signal-to-noise ranges ...

TranscriptomicsProfiling oxidative stress in Saccharomyces cerevisiae by oxidation of transcription factor Swi6p
Cell cycle sensing of oxidative stress in Saccharomyces cerevisiae by oxidation of a specific cysteine residue in the transcription factor Swi6p. Yeast cells begin to bud and enter S phase when growth conditions are favourable during G1 phase. When subjected to oxidative stress, cells arrest at G1 d...
