The Abumrad lab directs the Adipocyte Biology and Molecular Nutrition (ABMN) Core designed to stimulate and support leading-edge research in nutrition/obesity. The Core provides expertise in cell metabolism, cell biology and access to an array of specialized equipment.

 The ABMN Core:

  1. Assists investigators in conduct of specialized metabolic studies: i) evaluation of adipose tissue morphology (cell size, macrophage infiltration, fibrosis), ii) functional assays of cellular uptake, utilization of substrate (fatty acids, glucose), lipolysis, autophagy, iii) cell/organelle imaging to visualize substrate metabolism, iv) cell respiration/ mitochondrial function.

  2. Provides investigators with access to and training in use of specialized equipment that is too costly for individual investigators.

  3. Provides expert consultation/training services in molecular nutrition to clinical researchers, to young investigators transitioning to independence and to established investigators new to nutrition.

  4. Partners with other Cores at Washington University to optimize research on nutrition and associated metabolic pathology.
