MetabolomicsProfiling aromatic amino acid metabolome in the human gut microbiota reveals Clostridioides difficile specific N-acyl amino acids

Owing to its compositional and chemical complexity, much of the gut microbiota metabolome remains poorly characterized. Aromatic amino acids (AAAs) have a history of being privileged substrates for the biosynthesis of diverse bioactive metabolites and thus represent a potentially rich source of b...

MetabolomicsStable Isotope–Assisted Plant Metabolomics: Combination of Global and Tracer-Based Labeling for Enhanced Untargeted Profiling and Compound Annotation
Untargeted approaches and thus biological interpretation of metabolomics results are still hampered by the reliable assignment of the global metabolome as well as classification and (putative) identification of metabolites. In this work we present an liquid chromatography-mass spectrometry (LC-MS)-b...

MetabolomicsPronounced uptake and metabolism of organic substrates by diatoms revealed by pulse-labeling metabolomics
Diatoms contribute as a major group of microalgae to approximately 20% of the global carbon fixation. In the plankton, these algae are exposed to a plethora of metabolites, especially when competing algae are lysed. In line with evidence that these phototrophs can also engage in heterotrophy we aske...

TranscriptomicsNovel male-biased expression in paralogs of the aphid slilmfast nutrient amino acid transporter expansion
A major goal of molecular evolutionary biology is to understand the fate and consequences of duplicated genes. In this context, aphids are particularly intriguing because the newly sequenced pea aphid genome is characterized by extraordinarily high levels of lineage-specific gene duplication relativ...

TranscriptomicsEffect of amino acid availability on vitamin B12 production in Lactobacillus reuteri
Recent functional genomics and genome-scale modeling approaches indicated that B12 production in Lactobacillus reuteri could be improved by medium optimization. Here we show that a series of systematic single amino acid omissions could significantly modulate the production of B12 from nearly undetec...

TranscriptomicsLet-7 coordinately suppresses components of the amino acid sensing pathway to induce autophagy
Macroautophagy (hereafter autophagy) is the major pathway by which macromolecules and organelles are degraded. Autophagy is regulated by the mTOR signaling pathway, which is the focal point for integration of metabolic information, with mTORC1 playing a central role in balancing biosynthesis and cat...

TranscriptomicsTranscription profiling by array of yeast gcn2, gcn4 and gln3 deletion mutants treated with rapamycin or 3-amino-1,2,4-triazole (3-AT)
Two nutrient sensing and regulatory pathways, the general amino acid control (GAAC) and the target of rapamycin (TOR), control yeast growth and metabolism in response to changes in nutrient availability. Starvation for amino acids activates the GAAC pathway, involving Gcn2p phosphorylation of eIF2 ...

TranscriptomicsGenetic deletion or pharmacologic blockade of the amino acid transporter Slc6a14 in mice suppresses breast cancer induced by Polyoma middle T oncogene
Tumor cells have an increased need for amino acids. Mammalian cells cannot synthesize essential amino acids; they must obtain these amino acids via specific transporters. Glutamine, though a non-essential amino acid, is critical for tumor cells (glutamine addiction). Entry of amino acids into tumor ...
