Scientific Tracks Abstracts: Metabolomics
Metabolomics is the study of low molecular weight molecules or metabolites produced within cells and biological systems. It involves technologies, such as mass spectrometry (MS) and nuclear magnetic resonance spectrography (NMR), which can measure hundreds to thousands of unique chemical entities (UCE). The metabolome provides one of the most accurate reflections of cellular activity at the functional level and hence can be leveraged for discerning mechanistic information during different normal and disease states. In clinical samples metabolites are more stable than proteins or RNA. In fact, metabolomic profiling in basic, epidemiological, clinical and translational studies has revealed potential new biomarkers of disease and therapeutic outcome and led to novel mechanistic understanding of pathogenesis. These include the recent biomarkers for diabetes risk, novel metabolites associated with cancer, and the discovery of over 500 unique lipids in plasma. However, unlike genomics or even proteomics, the degree ofmetabolite complexity and heterogeneity within biological systems presents unique challenges requiring specialized skills and resources to overcome. An example of association of metabolomics predictors of body fat amount and distribution and associated risk with cancer will be discussed. Epidemiology studies with altered metabolite profiles in lung, prostate, and endometrial cancer will also be discussed.
