The Broad will provide both metabolomics and proteomics service for the TOPMed. Metabolomics. Metabolomic technologies provide the systematic biochemical characterization of human plasma and tissue samples. We have established a high-throughput metabolomics platform that measures over 600 known metabolites based on authentic standards, as well as thousands of LC-MS peaks that we are methodically working to characterize. Our methods integrate both targeted and non-targeted LC-MS approaches. We have rigorously addressed intra- and interassay variability, acquiring data at “population” level scale. In prior analyses in the Framingham Heart Study (FHS), the Diabetes Prevention Study, the Women’s Health Initiative and other cohorts, we have identified novel biomarkers of cardiometabolic disease and integrated genetic information and studies in model systems to identify novel biologic pathways. In response to Task Order Request for Proposals issued in 2017 for pilot metabolomics studies on 2000 MESA samples and in 2018 for CORE Year 3 metabolite profiling of approximately 8000 samples, we provided high quality targeted and nontargeted data delivered in a complete and timely manner, meeting deadlines in both cases. We are presently collaborating with MESA investigators to generate metabolomics data on approximately 8000 plasma samples for Data generation for CORE Year 4. Since the pilot studies, we have been responsive to TOPMed investigators working with metabolomics data and have supported and collaborated on data analysis. Based on these experiences, we seek to provide metabolomic capabilities in response to Task Order Request for Proposal (TORFP) #75N92020R0034; Centralized Omics REsource (CORE); Task Area 5: Metabolite Profiles using our high throughput, multidisciplinary approach.
