## Abstract

The Translational Biomarker Analytical Core (TBAC) Laboratory makes available to DRC 
investigators analytical techniques to support studies of diabetes mellitus, insulin resistance, 
intermediary metabolism, and medical consequences of diabetes in human subjects and animal 
models. The services provided are best based in a Core Laboratory because they require investigator 
consultation, special instrumentation and methods that are difficult or impracticable to establish in 
individual laboratories. In addition, this arrangement allows for coordinated attention to reliability and 
reproducibility of the assays employed. In investigations of glucose homeostasis, insulin secretion, 
dyslipidemia, hormone action, molecular genetics, or drug effects, it is essential to be able to monitor 
hormones such as insulin, C-peptide, glucagon, GLP-1, GIP, PYY, cortisol and catecholamines and 
such metabolites as glucose, FFA, glycerol, ketones, amino acids, and lipids. With the increasing 
technical capabilities to develop and validate novel disease biomarkers, one of the key functions of the 
Core is to expeditiously develop and inaugurate these new methods so that the research base can 
avail itself of these assays. In the past funding cycle, the Core provided ~80,000 assays to 33 DRC 
members supported by 81 grants. The resultant data have contributed to 17 new NIH grants, 
and 85 Core-supported publications (69 as primary, 16 as secondary Core). The SPECIFIC AIMS 
of the TBAC are: 1) To meet the high demand for a dynamic range of bioassays by the research base, 
enhancing efficiency, quality, and reproducibility, while minimizing costs. 2) To respond to members’ 
needs by introducing new assays and methods that leverage the expertise of the Core staff. 3) To 
provide expert advice to investigators and their associates on analytical methods, experimental design, 
and data interpretation. 4) To train junior investigators and post-doctoral fellows in practical skills in the 
Core methods and, if appropriate, transfer analytical methods to their own labs. 5) To facilitate access 
to targeted metabolomics/lipidomics determinations by the Columbia CTSA Biomarker Laboratory. 6) 
To facilitate access to experts in bioinformatics, kinetic studies and pathway analyses required to 
appropriately interpret metabolomics/lipidomics determinations and stable isotopes kinetic studies. 7) 
To facilitate collaborations among the research base, advertise available resources, and develop 
and/or facilitate investigator access to new technologies, such as MS-based methods to analyze and 
quantify metabolites. TBAC analytic and consultative capabilities are closely articulated with the 
other DRC Cores to provide an integrated approach to quantitative metabolic analyses (Fig. 1).
