MetabolomicsStable Isotope-Assisted Metabolomics for Deciphering Xenobiotic Metabolism in Mammalian Cell Culture
Xenobiotics are ubiquitous in the environment and modified abundantly in the human body by phase I and II metabolism. Liquid chromatography coupled to high resolution mass spectrometry is a powerful tool to investigate these biotransformation products. Here, we present a workflow based on stable iso...

MetabolomicsTranscriptomics and Metabolomics Reveal Alterations in Xenobiotic Metabolism and Appearance of Steroidal Alkaloid Metabolites in Mouse Livers after Tomato Consumption

SCOPE: Tomato consumption is associated with many health benefits including lowered risk for developing certain cancers. It is hypothesized that tomato phytochemicals are transported to the liver and other tissues where they alter gene expression in ways that lead to favorable he...

MetabolomicsUnraveling biomolecular and ecological mechanisms underlying the response of anammox consortia under xenobiotic stress by multi-omics strategy
Anaerobic ammonium oxidation (anammox) emerges as a sustainable solution for nitrogen removal in sewage, but it is susceptible to stress induced by xenobiotics that are ubiquitous in sewage. Despite wide recognition of this critical issue, a comprehensive understanding of the molecular and ecologica...

TranscriptomicsDiet and phenobarbital affect cholesterol homeostasis and drug metabolism
High cholesterol diet and xenobiotic treatment induce changes in cholesterol homeostasis and drug metabolism. Mice were either 7 days on high cholesterol diet or were treated with phenobarbital. Liver samples were analyzed using Sterolgene v0 cDNA microarrays. Sterolgene microarray is a tool designe...

MetabolomicsMicrobial transformation of dietary xenobiotics shapes gut microbiome composition

Diet is a major determinant of gut microbiome composition, and variation in diet-microbiome interactions may contribute to variation in their health consequences. Understanding individual differences requires mechanistic understanding of dietary xenobiotics-microbiome interactions. Here, we map i...

MetabolomicsSimultaneously discovering the fate and biochemical effects of pharmaceuticals through untargeted metabolomics
Untargeted metabolomics is an established approach in toxicology for characterising endogenous metabolic responses to xenobiotic exposure. Detecting the xenobiotic and its biotransformation products as part of the metabolomics analysis provides an opportunity to simultaneously gain deep insights int...

MetabolomicsRegulatory mechanisms for aromatic carbon metabolism in Comamonas testosteroni
Widely reported discrepancies between metabolic flux and transcripts or enzyme levels in bacterial metabolism imply complex regulation mechanisms need to be considered, especially in new bacterial platforms for bioremediation and bioproduction. Comamonas testosteroni strains, which metabolize variou...

MetabolomicsElucidation of xenoestrogen metabolism by non-targeted, stable isotope-assisted mass spectrometry in breast cancer cells

Environmental exposure to xenoestrogens, i.e., chemicals that imitate the hormone 17β-estradiol, has the potential to influence hormone homeostasis and action. Detailed knowledge of xenobiotic biotransformation processes in cell models is key when transferring knowledge learned from in vitro<...

TranscriptomicsXenobiotics shape the physiology and gene expression of the active human gut microbiome
The human gut is colonized by trillions of microorganisms that influence human health and disease through the metabolism of xenobiotics, including therapeutic drugs and antibiotics. The diversity and metabolic potential of the human gut microbiome have been extensively characterized, but it remains ...

GenomicsT-cell factor 4 and β-catenin chromatin occupancies pattern zonal liver metabolism.
β-catenin signaling can be both a physiological and an oncogenic pathway in the liver. It controls compartmentalized gene expression, allowing the liver to ensure its essential metabolic function. It is activated by mutations in 20 to 40% of hepatocellular carcinomas with specific metabolic features...
