Animal Models and Phenotyping
The function of this Core is to provide members of the Diabetes and Obesity Center with the expertise, resources and the facilities needed for animal husbandry and necropsy services and to maintain and phenotype murine models of diabetes and obesity.
The Core also assists Center members in developing new mouse models of diabetes, obesity and insulin resistance.
Aims of the Core
- Support current COBRE and Center projects. The Core provides state-of-the-art facilities and intellectual capability for the development and characterization of new and existing animal models used in diabetes and obesity research. The Core has developed and implemented standard procedures for the measurement of systemic insulin sensitivity and glucose tolerance.
- Educate and train investigators. The Core has installed a multi-user computer program (mLIMS) to track all animal breeding and colony maintenance. The Core routinely conducts formal and informal training sessions to impart the experience and the expertise gathered from several years of working with mouse models. The Core also assists individual investigators in designing appropriate phenotyping protocols, surgical procedures and tissue collection and storage protocols.
- Develop new protocols and techniques. The Core has and will continue to develop new mouse models of interest to investigators. It will expand its operations to support future needs and will develop state-of-the-art mouse models and develop new methods and new assays and modeling for metabolic phenotyping.
Facilities & Instrumentation
Portable GE Medical Systems Lunar PIXImus Dual-Energy X-Ray Absorptiometer (DEXA) Scan - The Lunar PIXImus Densitometer (GE Medical Systems) provides bone mineral and body composition (lean and fat body mass) composition results from total body imaging in less than 5 min.
This equipment is housed in the Delia Baxter building.
TSE PhenoMaster/LabMaster Metabolic Chamber System - A highly-flexible modular system for state-of-the-art automated metabolic and behavioral monitoring of small rodents.
It is located in a dedicated, environmentally-controlled room (12h:12h light:dark cycle; red light equipped for afterhours treatment; 150 ft2).
TSE PhenoMaster - Performs monitoring of individual mouse metabolic function including indirect calorimetry (O2 consumption, CO2 production, RER), food intake, water consumption, and ambulatory and fine motor activity (in X-axis; infrared sensors) recorded via LabMaster software.
The UofL Pathology & Bioanalytics Core offers several services for center members as well as other investigators and UofL faculty.
