The mission of the Animal Physiology Core is to assist investigators in the in vivo assessment of glucose and fatty acid metabolism, insulin sensitivity and energy homeostasis in mice and rats. It performs studies of body adiposity distribution and facilitates NMR spectroscopy, fMRI and microPET analysis and imaging of experimental models undergoing metabolic studies. The Core also provides specialized rodent surgeries for investigator laboratories and several cardiac functional assessments related to diabetic complications. Through collaborative efforts with the other Cores of the DRTC, the effects of defined pharmacological, dietary, environmental and genetic alterations are thoroughly characterized for their effects on glucose homeostasis, insulin action, and metabolism. To accomplish these goals, the Animal Physiology Core will: 1) advise investigators in designing metabolic studies relevant to the control of glucose homeostasis and insulin action in rodents;2) make available to investigators specialized measurements of whole body and tissue specific glucose sensitivity and insulin action including, but not limited to insulin, pancreatic and hyperglycemic clamp studies;3) provide specialized surgical models for the study of insulin sensitivity, energy balance, and glucose and fatty acid metabolism;4) offer instruction to students, postdoctoral fellows, investigators and technical staff in performing surgical and physiological techniques necessary to evaluate the controls of glucose homeostasis and insulin action;5) provide analysis of whole body carbohydrate/fatty acid oxidation, energy expenditure, feeding behavior, and locomotor activity using specialized metabolic (indirect calorimetry) and behavioral rodent cages;6) provide assessment of the effects of spontaneous (running wheel) or scheduled (treadmill) exercise on glucose homeostasis and metabolism;7) make available to investigators specialized measurements of rodent adipose tissue distribution using microCT and measurements of glycogen in liver and muscle, intrahepatic lipids and intramyocellular lipids using NMR;8) make available to investigators specialized measurements of brain energy and glucose utilization by functional MRI (fMRI) and microPET scanning;and 9) perform quantitative analyses of cardiac ischemia reperfusion injury and autonomic neuropathy. All these sen/ices are available to investigators new to diabetes research, as well as to investigators working on diabetes-related projects that can be enriched and extended by the use of the expertise and facilities of this core.

Public Health Relevance

The Animal Physiology Core provides cost effective, high quality resources that facilitate the scientific progress made by a large group of scientists committed to improve our understanding of the integrative physiology of diabetes in order to improve the treatment of patients with diabetes.
