MetabolomicsSystem-wide analysis of short-term response to high temperature in Pinus radiata

Pinus radiata seedlings, the most widely planted pine species in the world, were exposed to temperatures within a range mimicking future scenarios based on current models of heat increase. The short-term heat response in P. radiata was studied in detail by exploring the metabolo...

Metabolomicsliquid chromatography-mass spectrometry
Bacterial cells harvested at peak enzyme activity were subjected to untargeted metabolomic profiling to evaluate metabolic changes during straw degradation compared to control (CK) groups. Samples were extracted using pre-chilled methanol–water (4:1, v/v) and analyzed on a UHPLC-Q Exactive HF-X syst...

MetabolomicsMetabolism Disorder Promotes Isoproterenol-induced Myocardial Injury in Mice with High Temperature and High Humidity and High-Fat Diet

Isoproterenol (ISO) provides a simple and non-invasive method for inducing myocardial injury with lower mortality and higher reproducibility. Phlegm-damp syndrome, as known as “Tanshi” in Chinese, is one of Traditional Chinese Medicine (TCM) syndrome differentiation, which plays an important role...

MetabolomicsLiquid Chromatography-High-Resolution Mass Spectrometry-Based In Vitro Toxicometabolomics of the Synthetic Cathinones 4-MPD and 4-MEAP in Pooled Human Liver Microsomes
Synthetic cathinones belong to the most often seized new psychoactive substances on an international level. This study investigated the toxicometabolomics, particularly the in vitro metabolism of 2-(methylamino)-1-(4-methylphenyl)-1-pentanone (4-MPD) and 2-(ethylamino)-1-(4-methylphenyl)-1-pentanone...

MetabolomicsTranscriptome-and metabolome-based mechanisms of high-temperature adaptation in triploid rainbow trout (Oncorhynchus mykiss)

High-temperature stress critically challenges cold-water aquaculture; however, the size-dependent molecular mechanisms underlying thermal adaptation in triploid rainbow trout (Oncorhynchus mykiss) remain poorly understood. Here, we integrated transcriptomic and metabolomic profiling of liver tiss...

MetabolomicsComparison of Full-Scan, Data-Dependent, and Data-Independent Acquisition Modes in Liquid Chromatography-Mass Spectrometry Based Untargeted Metabolomics
Full-scan, data-dependent acquisition (DDA), and data-independent acquisition (DIA) are the three common data acquisition modes in high resolution mass spectrometry-based untargeted metabolomics. It is an important yet underrated research topic on which acquisition mode is more suitable for a given ...

MetabolomicsImproving global feature detectabilities through scan range splitting for untargeted metabolomics by high-performance liquid chromatography-Orbitrap mass spectrometry
Untargeted metabolomics aims at obtaining quantitative information on the highest possible number of low-molecular biomolecules present in a biological sample. Rather small changes in mass spectrometric spectrum acquisition parameters may have a significant influence on the detectabilities of metabo...

MetabolomicsImpact of collection conditions on the metabolite content of human urine samples as analyzed by liquid chromatography coupled to mass spectrometry and nuclear magnetic resonance spectroscopy (LC-MS assay)
There is a lack of comprehensive studies documenting the impact of sample collection conditions on metabolic composition of human urine. To address this issue, two experiments were performed at a three-month interval, in which midstream urine samples from healthy individuals were collected, pooled, ...

MetabolomicsLiquid chromatography coupled to high-resolution mass spectrometry metabolomics: A useful tool for investigating tumor secretome based on a three-dimensional co-culture model

Three-dimensional (3D) cell culture technologies, which more closely mimic the complex microenvironment of tissue, are being increasingly evaluated as a tool for the preclinical screening of clinically promising new molecules, and studying of tissue metabolism. Studies of metabolites released int...

MetabolomicsAutomated Label-free Quantification of Metabolites from Liquid Chromatography–Mass Spectrometry Data (Plasma)

Liquid chromatography coupled to mass spectrometry (LC-MS) has become a standard technology in metabolomics. In particular, label-free quantification based on LC-MS is easily amenable to large-scale studies and thus well suited to clinical metabolomics. Large-scale studies, however, require autom...
