Global metabolomics and integrative -omics (intOmics)
Metabolomics provides screening of targeted (~650) and untargeted (~2500) metabolites. Options for more detailed analyses include volcano plots, pathway enrichment and KEGG network optimization data. Metabolomic data can be integrated with (user provided) RNAseq using a metabolomics network analysis platform (IntOmix), for an optimized pathway analysis of relationships between metabolites and enzyme transcripts.

Metabolic flux and enrichment studies using MIMOSA
In this subcore, parameters of cellular and tissue metabolic flux are assessed by incorporation of stable isotope labeled tracers (e.g., 13C, 15N, 2D) into metabolism. The CMC uses the targeted mass isotopomer multi-ordinate spectral analysis (MIMOSA) platform to interpret stable isotope labeling patterns for calculation of rates of discrete steps in glycolytic and mitochondrial metabolism. Such measurements can be used to identify differences in fuel usage (e.g., glycolysis vs. beta-oxidation), and non-oxidative (reductive carboxylation, anaplerosis and cataplerosis) contributions to the TCA cycle.

Islet isolation and function
In this subcore, our technical expertise in isolating rodent islets including rats, mice and most recently ground squirrel islets, from the pancreas ex-vivo allows researchers to study the intact islets for their studies or to proceed with substrate stimulated insulin secretion functional studies using our BioRep Technologies Islet Perfusion Systems (8-channel and 12-channel) offered by our core. For non-rodent islet studies, human donor islet procurement assistance as well as unction studies are also offered.
