#METABOLOMICS WORKBENCH stringek_20150915_9129281_mwtab.txt DATATRACK_ID:379 STUDY_ID:ST000256 ANALYSIS_ID:AN000405 VERSION 1 CREATED_ON 01-03-2020 #PROJECT PR:PROJECT_TITLE Signal Intensities Derived from Different NMR Probes and Parameters Contribute PR:PROJECT_TITLE to Variations in Quantification of Metabolites PR:PROJECT_TYPE Cross-center Quantitative NMR Urine Metabolomics Study PR:PROJECT_SUMMARY We discovered that serious issues could arise that may complicate interpretation PR:PROJECT_SUMMARY of metabolomic data when identical samples are analyzed at more than one NMR PR:PROJECT_SUMMARY facility, or using slightly different NMR parameters on the same instrument. PR:PROJECT_SUMMARY This is important because cross-center validation metabolomics studies are PR:PROJECT_SUMMARY essential for the reliable application ofmetabolomics to clinical biomarker PR:PROJECT_SUMMARY discovery. To test the reproducibility of quantified metabolite data at multiple PR:PROJECT_SUMMARY sites, technical replicates of urine samples were assayed by 1D-1H-NMR at the PR:PROJECT_SUMMARY University of Alberta and the University of Michigan. Urine samples were PR:PROJECT_SUMMARY obtained from healthy controls under a standard operating procedure for PR:PROJECT_SUMMARY collection and processing. Subsequent analysis using standard statistical PR:PROJECT_SUMMARY techniques revealed that quantitative data across sites can be achieved, but PR:PROJECT_SUMMARY also that previously unrecognized NMR parameter differences can dramatically and PR:PROJECT_SUMMARY widely perturb results. We<br>present here a confirmed validation of NMR PR:PROJECT_SUMMARY analysis at two sites, and report the range and magnitude that common NMR PR:PROJECT_SUMMARY parameters involved in solvent suppression can have on quantitated metabolomics PR:PROJECT_SUMMARY data. Specifically, saturation power levels greatly influenced peak height PR:PROJECT_SUMMARY intensities in a frequency-dependent manner for a number of metabolites, which PR:PROJECT_SUMMARY markedly impacted the quantification of metabolites. We also investigated other PR:PROJECT_SUMMARY NMR parameters to determine their effects on further quantitative accuracy and PR:PROJECT_SUMMARY precision. Collectively, these findings highlight the importance of and need for PR:PROJECT_SUMMARY consistent use of NMR parameter settings within and across centers in order to PR:PROJECT_SUMMARY generate reliable, reproducible quantified NMR metabolomics data.
