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.
