项目摘要

Project Summary - Overall This application is in response to PAR-16-415, Centers of Biomedical Research Excellence (COBRE) (P20). The proposed phase 1 center (P1C) is built on a strong foundation and long-term commitment to hibernation research at the University of Alaska's Institute of Arctic Biology (IAB). The objective of the P1C is to use the expertise at IAB, in particular that of Dr. Kelly Drew, the PI, to build and strengthen the University of Alaska's hibernation research infrastructure. The plan involves guiding the career development of three investigators, experienced in research, but who have yet to receive R01s from NIH, and to guide the career development of new investigators currently showing an interest in hibernation research. The long-term goal, likely beyond the life of the P1C, is to apply what is learned about the mechanisms underlying the physiological changes in hibernation to as yet unresolved issues relevant to metabolism and metabolic diseases such as disuse muscle atrophy, sarcopenia, obesity, type 2 diabetes and cardiovascular diseases in humans. The center will support the research and career development of both experienced scientists and those getting their start in research. The center will have a focus on all stages of research from basic through translational. By defining translational paths for discoveries in hibernation, the P1C will contribute to the career development of the investigators. Strong administrative and scientific leadership will accomplish the goals of this P1C through the following four Specific Aims (SA): SA1. Establish an organizational structure and research infrastructure that will support and promote a multidisciplinary framework to define mechanisms of metabolic adaptations in hibernating mammals. SA 2. Enhance the careers of P1C project PIs as well as new investigators leading pilot projects through the P1C in order to allow them to compete successfully for NIH individual research grants. SA3. Support research projects and pilot projects aimed at developing an understanding of physiological, genetic and gut microbial mechanisms in hibernation and how these mechanisms may play a role in treating disuse muscle atrophy or sarcopenia. SA 4. Support clinical research projects related to the theme of the center. Seasonal hibernators arguably display the most dramatic natural alterations in metabolism, appetite, diet, body composition and body temperature of any mammal across their annual cycle. Such extremes offer insight into regulatory mechanisms, and druggable targets that would be less obvious in traditional pre-clinical models. This P1C focuses on genetic and gut microbial mechanisms related to protein synthesis and preservation of skeletal muscle during prolonged disuse and fasting in hibernating mammals. Once completed new investigators will be equipped to identify and translate treatments to promote anabolic sensitivity and preservation of muscle mass and strength. Such discoveries have the potential to save $1 billion per year in health-care costs in the US by reducing risk for disability, hospitalization, and death in older and mobility impaired adults.

项目概要-总体本申请是为了响应PAR-16-415，生物医学研究卓越中心（COBRE）（P20）。拟议的第1阶段中心（P1 C）建立在坚实的基础上，并长期致力于冬眠阿拉斯加大学北极生物学研究所（IAB）的一项研究。P1 C的目标是使用在IAB的专业知识，特别是凯利德鲁博士，PI，建立和加强阿拉斯加大学的冬眠研究基础设施。该计划涉及指导三名调查员的职业发展，在研究方面经验丰富，但尚未从NIH获得R 01，并指导职业发展的人，新的研究人员目前对冬眠研究表现出兴趣。长期目标，可能超过生命的P1 C，是应用什么是了解机制的生理变化，冬眠到尚未解决的问题有关的新陈代谢和代谢疾病，如废用肌肉萎缩、肌肉减少症、肥胖症、2型糖尿病和心血管疾病。中心将支持有经验的科学家和刚开始从事研究的科学家的研究和职业发展。该中心将重点关注从基础到转化的所有阶段的研究。通过定义平移 P1 C将有助于研究人员的职业发展。强有力的行政和科学领导将通过以下四个方面实现P1 C的目标具体目标（SA）：SA 1。建立一个组织结构和研究基础设施，促进多学科框架，以确定冬眠哺乳动物的代谢适应机制。 SA 2.提升P1 C项目PI以及新调查员领导试点项目的职业生涯， P1 C，以使他们能够成功地竞争NIH个人研究赠款。SA 3.支持研究旨在了解生理、遗传和肠道微生物的项目和试点项目冬眠机制以及这些机制如何在治疗废用性肌肉萎缩或肌肉减少症SA 4.支持与中心主题相关的临床研究项目。季节性冬眠动物可以说，在新陈代谢、食欲、饮食、身体组成和任何哺乳动物的体温在它们的一年周期。这种极端情况提供了对监管的深入了解。机制，以及在传统的临床前模型中不太明显的药物靶点。P1C 专注于与蛋白质合成和骨骼保存相关的遗传和肠道微生物机制在冬眠的哺乳动物中长时间不用和禁食时的肌肉。一旦完成，新的研究人员将配备识别和翻译治疗，以促进合成代谢的敏感性和肌肉质量的保存和力量这些发现有可能在美国每年节省10亿美元的医疗费用，降低老年人和行动不便的成年人的残疾、住院和死亡风险。
