This project will take advantage of the techniques developed in old Project 1 to quantify glucose oxidative and fatty acid metabolism in the rodent. The project will utilize both rat (ZDF Zucker) and mouse models (MHC-PPAR or MCK-PPAR) of diabetes to evaluate in these well controlled models, the differences in metabolic profile between diabetic animals and normal controls as well as the effect of the therapies being utilized in humans in the instrumentation project. An important advantage of the animal model is the ability to evaluate the impact that genetic changes have on cardiac metabolism and other tissues resulting from these therapies. This project will also utilize animal models to validate the radiopharmaceuticals being developed in Project 1. The project will, therefore, interact with both other projects. The radiopharmaceuticals for the metabolism studies will be produced in the cyclotron/radiochemistry core and this project will take advantage of the advances in microPET technology being carried out in the instrumentation core. This project will address the general hypothesis that rodent models of cardiac disease in conjunction with microPET and microCT imaging can be used to evaluate metabolic changes in the disease as well as changes caused by drug therapies. To this aim we will evaluate three models of diabetes and selected therapies.

这个项目将利用旧项目1中开发的技术来量化啮齿类动物的葡萄糖氧化和脂肪酸代谢。该项目将利用RAT(ZDF) 为了在这些控制良好的模型中评估糖尿病动物(MHC-PPAR或MCK-PPAR)和小鼠(MHC-PPAR或MCK-PPAR)的代谢特征，糖尿病动物和正常对照组之间的代谢谱差异，以及在仪器项目中正在用于人类的治疗方法的效果。动物模型的一个重要优势是能够评估基因变化对心脏新陈代谢和这些疗法导致的其他组织的影响。该项目还将利用动物模型来验证放射性药物 在项目1中开发。因此，该项目将与其他两个项目交互。这个 用于新陈代谢研究的放射性药物将在回旋加速器/放射化学核心中生产，该项目将利用仪器核心中正在进行的微型PET技术的进步。这个项目将解决一个普遍的假设，即心脏疾病的啮齿动物模型结合microPET和microCT成像可以用来评估疾病中的代谢变化以及药物治疗引起的变化。对这件事 目的评价糖尿病的三种模型和选择的治疗方法。
