MetabolomicsMetaboKit: a comprehensive data extraction tool for untargeted metabolomics (Standard mixture assay)

We have developed MetaboKit, a comprehensive software package for compound identification and relative quantification in mass spectrometry-based untargeted metabolomics analysis. In data dependent acquisition (DDA) analysis, MetaboKit constructs a customized spectral library with compound identit...

MetabolomicsMulti-omics phenotyping of the gut-liver axis reveals metabolic perturbations from a low-dose pesticide mixture in rats
Health effects of pesticides are not always accurately detected using the current battery of regulatory toxicity tests. We compared standard histopathology and serum biochemistry measures and multi-omics analyses in a subchronic toxicity test of a mixture of six pesticides frequently detected in foo...

MetabolomicsReal-world neonicotinoid mixture exposure reveals synergistic cytotoxicity and divergent pathway vulnerabilities in human cell lines

In this study, five human cell lines (A2780, Chang liver, HEK293T, HeLa, and HepG2) were used as models and exposed to mixtures of neonicotinoids (NEOs) and their metabolites. The mixture concentrations were prepared based on human biomonitoring data to reflect the actual detected levels of NEOs ...

MetabolomicsLimited oxygen availability in standard cell culture alters metabolism and function in terminally differentiated cells

Cell culture is generally considered to be hyperoxic. However, the importance of cellular oxygen consumption is often underappreciated, with rates of oxygen consumption often sufficient to cause hypoxia at cell monolayers. We initially focused on cultured adipocytes as a terminally differentiated...

MetabolomicsUntargeted metabolomics of long-term drug intervention under standard diet in mice associated with lifespan

This study investigates urinary metabolic differences in young mice, aged mice, and aged mice supplemented with long-term drug intervention under standard diet. Untargeted metabolomics was performed using UHPLC-MS/MS in both positive (POS) and negative (NEG) ionization modes. The dataset provides...

MetabolomicsAbsolute quantification of metabolites in tomato fruit extracts by fast 2D NMR (Calibration Standard 700 MHz samples)

Quantitative NMR metabolomics is a powerful tool to have access to valuable information on metabolism. Unfortunately, the quantitative analysis of metabolic samples is often hampered by peak overlap. Two-dimensional (2D) spectroscopy offers a promising alternative and quantitative results can be ...

MetabolomicsAbsolute quantification of metabolites in tomato fruit extracts by fast 2D NMR (Calibration Standard 500 MHz samples)

Quantitative NMR metabolomics is a powerful tool to have access to valuable information on metabolism. Unfortunately, the quantitative analysis of metabolic samples is often hampered by peak overlap. Two-dimensional (2D) spectroscopy offers a promising alternative and quantitative results can be ...

TranscriptomicsToxicogenomic responses in rainbow trout hepatocytes exposed to model chemicals and a synthetic mixture
Comparison of gene expression of exposed versus non-exposed Oncorhynchus mykiss hepatocytes to four model chemicals and a synthetic mixture. Hepatocytes were exposed for 24 hours to a single chemical and a synthetic mixture of 10 nM 17 alpha-ethinylestradiol (EE2), 0.75 nM 2,3,7,8-tetrachloro-di-be...

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 ...
