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...

MetabolomicsUHPLC-MS/MS-Based Identity Confirmation of Amino Acids Involved in Response to and Side Effects from Antiseizure Medications

Real-time breath analysis using secondary electrospray ionization coupled with high-resolution mass spectrometry is a fast and noninvasive method to access the metabolic state of a person. However, it lacks the ability to unequivocally assign mass spectral features to compounds due to the absence...

MetabolomicsDynamic partitioning of branched-chain amino acids-derived nitrogen supports renal cancer progression

Metabolic reprogramming is critical for tumor initiation and progression. However, the exact impact of specific metabolic changes on cancer progression is poorly understood. Here, we integrate multimodal analyses of primary and metastatic clonally-related clear cell renal cancer cells (ccRCC) gro...

MetabolomicsMapping the metabolism of five amino acids in bloodstream form Trypanosoma brucei using U-13C-labelled substrates and LC–MS
The metabolism of the parasite Trypanosoma brucei has been the focus of numerous studies since the 1940s. Recently it was shown, using metabolomics coupled with heavy-atom isotope labelled glucose, that the metabolism of the bloodstream form parasite is more complex than previously thought. The pres...

MetabolomicsMultiomic profiling of medulloblastoma reveals subtype-specific targetable alterations at the proteome and N-glycan level (Amino acid profiling)

Medulloblastomas (MBs) are malignant pediatric brain tumors that are molecularly and clinically very heterogenous. The application of omics technologies - mainly studying nucleic acids - has significantly improved MB classification and stratification, but treatment options are still unsatisfactor...

MetabolomicsAirway metabolic profiling during Streptococcus pneumoniae infection identifies branched chain amino acids as signatures of upper airway colonisation

Streptococcus pneumoniae is a leading cause of community-acquired pneumonia and bacteraemia and is capable of remarkable phenotypic plasticity, responding rapidly to environmental change. Pneumococcus is a nasopharyngeal commensal, but is responsible for severe, acute infections followin...

MetabolomicsAromatic amino acids metabolism shapes autophagy mediated adaptation to iron deprivation in glioma

GBM displays profound iron dependence and metabolic plasticity, yet how iron deprivation interfaces with stress-response pathways and amino acid metabolism in glioma remains incompletely understood. DFO, an iron chelator and hypoxia mimetic, is widely used experimentally, but the integration of a...

MetabolomicsThe Formation of Phenol and Indole Flavor Substances in Stinky Tofu Brine Based on Metabolism of Aromatic Amino Acids

Understanding the formation mechanism of the flavor compounds in stinky tofu brine is crucial for controlling the flavor quality of Changsha stinky tofu. Dynamic changes in associated bacteria, enzymes, and differential metabolites in the metabolic pathway of aromatic amino acids in brine were in...

MetabolomicsMetabolic profilings of rat INS-1 β-cells under changing levels of essential amino acids

Application of mass spectrometry enables the detection of metabolic differences between organisms with different nutritional settings. Divergence in the metabolic fingerprints of rat pancreatic INS-1 β-cells were systematically captured with regard to 10 individual essential amino acid (EAA) avai...

MetabolomicsA Comprehensive and Ultrasensitive Isotope Calibration Method for Soil Amino Compounds Using Orbitrap Mass Spectrometry
Bound amino compounds (amino acid and amino sugar polymers) comprise a significant proportion (~40%) of soil organic nitrogen and therefore represent an essential source of nitrogen for plant and microbial nutrition. The analysis of their content and isotope enrichment still represents a significant...
