DESCRIPTION (provided by applicant): The UMass Mouse Metabolic Phenotyping Center involves a multidisciplinary group of investigators at UMass who perform an array of novel and sophisticated metabolic experiments using state-of-the-art equipment for the purpose of investigating transgenic mice useful for understanding diabetes and its complications. The goal of the UMass MMPC is to provide comprehensive metabolic characterization of transgenic mice using unique and standardized techniques mostly involving, in vivo and physiological setting that are complemented by analytical experiments using serum/tissue samples and measure of cardiovascular complications using non-invasive procedures in mice. The UMass MMPC consists of 3 Phenotyping Cores: 1) Metabolism Core applies hyperinsullnemic-euglycemic clamp to assess insulin sensitivity and glucose metabolism in individual organs, hyperglycemic clamp to assess pancreatic beta-cell function in conscious mice, metabolic cages to assess energy expenditure, activity and food intake, and 1H-MRS to measure fat/lean/water mass in mice, 2) Analytical Core uses Luminex. Meso Scale Discovery, and Cobas Clinical Chemistry Analyzer to provide a high-throughput and multiplexed measurement of serum/tissue levels of hormones, cytokines and metabolites, performs molecular experiments to examine insulin signaling, and conducts histological studies to examine tissues, 3) Cardiovascular Complications Core uses Vevo2100 In Vivo Imaging System to conduct echocardiography and tissue Doppler imaging, and CODA blood pressure device to examine cardiovascular abnormalities associated with diabetes. Mice provided by the users are overseen by the Animal Care Core that processes the receiving, quarantine, and housing of mice. Lastly, financial and administrative operation, research & development program, and website & database are managed by the Administrative Core. Overall, the aim of the UMass MMPC is to become an NIH-funded national center that offers elegant and standardized techniques and scientific expertise using a fee-for-service structure to characterize the metabolic and organ function phenotypes of transgenic mice and provide important insights into the mechanism of diabetes and its complications.

描述(申请人提供)：加州大学马萨诸塞州大学小鼠代谢表型鉴定中心涉及多学科的研究小组，他们使用最先进的设备进行一系列新颖和复杂的代谢实验，目的是研究有助于了解糖尿病及其并发症的转基因小鼠。UMassMMPC的目标是使用独特和标准化的技术提供转基因小鼠的全面代谢特征，主要涉及体内和生理环境，并辅之以使用血清/组织样本进行分析实验，以及使用非侵入性程序测量小鼠的心血管并发症。UMassMMPC由3个表型核心组成：1)代谢核心使用高胰岛素-正常血糖钳来评估各个器官的胰岛素敏感性和葡萄糖代谢，高血糖钳用于评估清醒小鼠的胰岛β细胞功能，代谢笼用于评估能量消耗、活动和食物摄入量，以及1H-MRS用于测量小鼠的脂肪/瘦肉/水分质量，2)分析核心使用Luminex。3)心血管并发症核心公司使用Vivo成像系统中的Vevo2100进行超声心动图和组织多普勒成像，CODA血压仪用于检查与糖尿病相关的心血管异常。由用户提供的老鼠由动物关怀核心监督，该核心负责接收、隔离和安置老鼠。最后，财务和行政运作、研发计划、网站和数据库由行政核心管理。总体而言，UMassMMPC的目标是成为由NIH资助的国家中心，提供优雅和标准化的技术和科学专业知识，使用收费服务结构来表征转基因小鼠的代谢和器官功能表型，并为糖尿病及其并发症的机制提供重要的见解。
