Untargeted metabolomics.
Along with genes and proteins, metabolites play important roles in sustaining life. Their functions include "primary" functions in metabolism and energy storage, as well as "secondary" functions in cell-to-cell signaling, metal acquisition, and virulence. There remains much to be learned about the in vivo roles of metabolites. Approaches that accelerate measurement of metabolite levels directly...
متن کاملUntargeted metabolomics suffers from incomplete data analysis
Introduction: Untargeted metabolomics is a powerful tool for biological discoveries. Significant advances in computational approaches to analyzing the complex raw data have been made, yet it is not clear how exhaustive and reliable are the data analysis results. Objectives: Assessment of the quality of data analysis results in untargeted metabolomics. Methods: Five published untargeted metabolo...
متن کاملmetaXCMS: second-order analysis of untargeted metabolomics data.
Mass spectrometry-based untargeted metabolomics often results in the observation of hundreds to thousands of features that are differentially regulated between sample classes. A major challenge in interpreting the data is distinguishing metabolites that are causally associated with the phenotype of interest from those that are unrelated but altered in downstream pathways as an effect. To facili...
متن کاملTargeted, LCMS-based Metabolomics for Quantitative Measurement of NAD+ Metabolites
Nicotinamide adenine dinucleotide (NAD(+)) is a coenzyme for hydride transfer reactions and a substrate for sirtuins and other NAD(+)-consuming enzymes. The abundance of NAD (+), NAD(+) biosynthetic intermediates, and related nucleotides reflects the metabolic state of cells and tissues. High performance liquid chromatography (HPLC) followed by ultraviolet-visible (UV-Vis) spectroscopic analysi...
متن کاملDissecting Bottromycin Biosynthesis Using Comparative Untargeted Metabolomics
Bottromycin A2 is a structurally unique ribosomally synthesized and post-translationally modified peptide (RiPP) that possesses potent antibacterial activity towards multidrug-resistant bacteria. The structural novelty of bottromycin stems from its unprecedented macrocyclic amidine and rare β-methylated amino acid residues. The N-terminus of a precursor peptide (BtmD) is converted into bottromy...
