Objectives: The objective of this equipment request is to obtain a state-of-the-art instrument to measure mitochondrial function in order to serve the research needs of investigators at the VA Portland Health Care System facility (VAPORHCS). In fiscal year 2018, VAPORHCS scientists were successful in competing for over $32 million in research grants from the VA, NIH, DOD and other sources. The VAPORHCS ranks 7th among all VAs nationwide in total research funding. There are 10 career development award or K-award recipients currently being trained here. Research is conducted in a total of 96,000 square feet of wet and dry lab space that supports programs in basic science, clinical research, rehabilitation, health services, cooperative studies, epidemiology and outcomes research. VAPORHCS is home to Centers of Excellence funded by the VA in Auditory Research and Health Services Research, and an NIH- funded Alcohol Research Center. Clinical programs awarded to the VAPORHCS include a NODES, NAVIGATE, MVP recruiting site, MIRECC, PADRECC, Centers for Multiple Sclerosis and Epilepsy, and Centers funded by QUERI and AHRQ. Plan: The plan is to obtain a Seahorse analyzer and locate it in the Portland VA facility to serve as a shared resource for VA investigators whose research involves measurement of mitochondrial respiration. Planned studies by the six VA-funded investigators include: measurement of mitochondrial respiration for: 1) the evaluation of candidate therapies in cell culture and animal models of Alzheimer’s disease, 2) evaluation of antimalarial drugs, 3) evaluation of drugs for the treatment of toxoplasmosis, 4) evaluation of the functional significance of succinate dehydrogenase mutations in stromal cell cancer cells, 5) evaluation of candidate therapies in a toxin model of Parkinson’s disease, and 6) evaluation of the effects of traumatic brain injury upon brain cell mitochondria. Once the instrument is in place, additional investigators are expected to take advantage of it. Methods: The tissue source for the measurements will vary across the respective laboratories, with mitochondrial respiration measured in cultured cells, in parasites, and in mitochondria isolated from brain tissue, depending on the research program. The Seahorse analyzer measures basal and maximum mitochondrial energy consumption and a number of other metrics are calculated from these values. Clinical relevance: The investigators participating in this request perform research which is intended to be translated to clinical application, and several have advanced their preclinical work to clinical trials, including treatments for Alzheimer’s disease, cancer, malaria, toxoplasmosis, and traumatic brain injury. The research supported by this instrument consequently has a high likelihood of leading to interventions to improve the health of veterans. Relevance to the VA’s mission: The treatment of neurodegenerative disease, cancer, infectious disease, and traumatic brain injury are all important for the VA’s mission. Two of the conditions under study are especially relevant to the VA: Parkinson’s disease is a service- connected illness for veterans with a history of exposure to Agent Orange exposure and traumatic brain injury is the signature injury for veterans of recent conflicts in Iraq and Afghanistan.

目标：本设备申请的目标是获得一种最先进的仪器，以 测量线粒体功能，以满足退伍军人管理局研究人员的研究需要 波特兰医疗保健系统设施(VAPORHCS)。2018财年，VAPORHCS科学家 成功地从退伍军人事务部、美国国立卫生研究院、国防部获得了超过3200万美元的研究拨款 和其他来源。VAPORHCS在全国所有VAS的研究总量中排名第7 资金问题。目前有10名职业发展奖或K奖获得者正在接受培训 这里。研究是在总共9.6万平方英尺的干湿实验室空间中进行的 支持基础科学、临床研究、康复、卫生服务等项目， 合作研究、流行病学和成果研究。VAPORHCS是 由退伍军人事务部资助的卓越听觉研究和卫生服务研究，以及美国国立卫生研究院- 资助酒精研究中心。授予VAPORHCS的临床项目包括 节点，导航，MVP招聘网站，MIRECC，PADRECC，多发性硬化症中心 和癫痫，以及QUERI和AHRQ资助的中心。 计划：计划获得一台海马分析仪，并将其放置在波特兰退伍军人管理局的设施中进行服务 作为退伍军人管理局调查人员的共享资源，他们的研究涉及测量 线粒体呼吸作用。退伍军人管理局资助的六名调查人员计划进行的研究包括： 线粒体呼吸的测量用于：1)细胞内候选治疗的评估 阿尔茨海默病的培养和动物模型，2)抗疟疾药物的评价，3) 治疗弓形虫病的药物评价，4)功能评价 基质细胞癌细胞中琥珀酸脱氢酶突变的意义，5)评估 帕金森氏病毒素模型的候选治疗方法，以及6)对 创伤性脑损伤对脑细胞线粒体的影响。一旦仪器就位，额外的 预计调查人员将利用这一点。 方法：测量的组织来源在不同的实验室会有所不同， 在培养细胞、寄生虫和线粒体中测量线粒体呼吸 从脑组织中分离出来，这取决于研究计划。海马氏分析仪 测量基础和最大线粒体能量消耗以及其他一些 指标是根据这些值计算得出的。 临床相关性：参与此请求的研究人员进行的研究 打算转化为临床应用，有几个已经推进了他们的临床前 致力于临床试验，包括治疗阿尔茨海默病、癌症、疟疾、 弓形虫病和创伤性脑损伤。这台仪器支持的研究 因此，很有可能导致采取干预措施来改善退伍军人的健康。 与退伍军人管理局的使命相关：治疗神经退行性疾病、癌症、 传染病和创伤性脑损伤对退伍军人管理局的任务都很重要。其中两个 研究中的情况与退伍军人管理局特别相关：帕金森病是一项服务- 有橙剂暴露史和退伍军人相关疾病 创伤性脑损伤是最近在伊拉克和伊拉克冲突中退伍军人的标志性损伤 阿富汗。
