The Adipocyte Biology and Molecular Nutrition Core (ABMN Core) is specifically tailored to meet the needs of Nutrition Obesity Research Center (NORC) investigators in basic and clinical departments who wish to conduct nutrition- or obesity- related molecular research. The ABMN provides support for the study of adipose tissue biology and of the molecular basis of nutritional effects on metabolism in health and disease. Such studies often require specific methods, equipment and expertise that are difficult to assemble by individual investigators and present a barrier to those who are new to this field. Therefore, the overall objective of the ABMN is to provide NORC researchers with access to the training, expertise, and facilities needed for comprehensive study of adipose tissue and of molecular aspects of nutritional research.

Core Description

The purpose of the NORC Adipocyte Biology and Molecular Nutrition (ABMN) Core is to provide:

  1. access to highly specialized facilities and equipment (e.g., a tissue culture facility, a transfection system, a high resolution respirometer for assessing the metabolic state of biopsy samples, cells or isolated mitochondria, a Counter Multisizer for adipocyte sizing, real-time PCR machines and Li-Cor Odyssey for protein detection) and technical expertise for its operation;
  2. assistance with specialized assays to evaluate: (i) adipocyte metabolic activity (e.g., glucose transport, glucose incorporation into glycogen, fatty acid transport, fatty acid incorporation into major lipid fractions, fatty acid oxidation, adipocyte lipolysis), (ii) adipose tissue morphology, (iii) adipose tissue macrophage content, and (iv) adipocyte gene and protein expression. In addition, the ABMN Core provides training for investigators (with special focus on young investigators), their staff, and research fellows in these areas of research, both in the form of one-on-one hands-on instruction.
