1 Stable Isotope and Metabolomics Core Facility AECOM Diabetes Center The Einstein Stable Isotope & Metabolomics Core is within the NIH funded Diabetes Research Center at Einstein and anchors the CMCR Metabolomics Core. The Core uses stable isotope flux and metabolite profiling to help formulate and test hypotheses about the metabolic consequences of various changes in gene expression and protein function, in order to guide further integrative systems biology analyses of the underlying mechanisms in diabetes, insulin resistance, obesity, and diabetic complications. The Core objectives includes assessments of plasma, urine and tissue metabolite profiles for diagnosis/characterization of physiological and pathophysiological states. These include key metabolites in the glycolytic, gluconeogenic, pentose phosphate, and tricarboxylic cycle pathways, fatty acid oxidation and complex lipids, such as ceramides, diacylgylcerols, triacylglycerols (TAGs), and phospholipids. In the CMCR framework, the Core will use these methodologies to explore the specific effects that radiation has on the metabolic network of each organ, and to explore the metabolic consequences of protein modification, by radiation, on the function of the metabolic network.
