Chemical Isotope Labeling LC-MS for Human Saliva and Urine Metabolomics

  • The objective of this work was to employ differential 13C/12C dansyl chloride (DnsCl) derivatization strategies for qualitative and quantitative profiling of amine- and phenol-containing metabolites by liquid chromatography electrospray ionization Fourier Transform ion cyclotron resonance mass spectrometry (LC-ESI FT-ICR-MS). A method based on the use of this isotope labeling LC-MS platform was optimized for human salivary metabolome analysis, aiming for the discovery of metabolite biomarkers in mild cognitive impairment (MCI) and Alzheimer’s diseases (AD). In addition, a large scale metabolomics study was performed on 100 urine samples taken during a 3 continuous day period. All samples were analyzed using the isotope labelling liquid chromatography mass spectrometry methodology. A pragmatic approach combining well-established statistical tools was developed to process this large data set in order to generate metabolic profiles of those samples.
