Roche Real-Time Polymerase Chain Reaction Workflow System

描述（由申请人提供）：我们正在申请罗氏实时聚合酶链反应（PCR）工作流程系统，该系统具有用于组织制备（MagNA Lyser），核酸分离（MagNA Pure Compact）和实时PCR （LightCycler 480）的自动化组件。LightCycler 480是一种高通量实时PCR仪器，可检测和定量核酸序列，具有96孔和384孔板容量。该PCR工作流程系统非常易于使用，配有功能强大的软件，使研究者能够在3-4小时内从组织到核酸定量。该仪器将被安置在Bosomworth健康科学研究大楼的微阵列核心研究设施中，并将由毒理学研究生中心以及解剖学和神经生物学部门的教师使用。参与此申请的调查小组包括7名主要使用nih资助项目的教员，以及3名次要使用的教员。研究项目多种多样，但主要围绕三个主题：1)氧化应激诱导的组织损伤和癌症；2)DNA损伤、修复和诱变；3)基因表达的激素调节。我们打算将该仪器用于生物样品中RNA转录物和DNA靶点的高通量实时定量分析，以及检测癌症重要基因的单核苷酸多态性（SNP）。正如每位研究者的研究项目所表明的那样，拟议仪器的可用性将显著提高他们研究的范围和及时性。最重要的是，它将允许科学家们在他们资助的研究项目中确定对令人兴奋的发现的追求，而不是现有仪器的可用性。这个共享的多学科研究设施的总体目标是利用这一先进的技术资源开展当今生物医学研究的前沿研究，并培养我们的博士生和博士后使用这些现代方法，使他们能够发展成为成功的独立研究者。我们的研究人员所解决的研究问题与癌症相关的主要公共卫生问题高度相关，包括肿瘤形成机制、癌症化疗药物有效性（缺乏）的原因，以及对女性健康重要的激素对基因的调节。

DESCRIPTION (provided by applicant): We are requesting a Roche real-time polymerase chain reaction (PCR) Workflow System with automated components for preparation of tissues (MagNA Lyser), isolation of nucleic acids (MagNA Pure Compact), and a real-time PCR (LightCycler 480). The LightCycler 480 is a high throughput real- time PCR instrument that detects and quantifies nucleic acid sequences, and has a 96- and 384-well plate capacity. This PCR Workflow System is very easy to use, is accompanied by powerful software, and enables an investigator to go from tissue to nucleic acid quantitation in 3-4 hours. This instrument will be housed in the MicroArray Core Research Facility of the University in the Bosomworth Health Sciences Research Building, and will be used by faculty in the Graduate Center for Toxicology, and in the Department of Anatomy and Neurobiology. The group of investigators participating in this application includes seven faculty with NIH-supported grant projects who are major users, and three additional faculty who are minor users. The research projects are diverse, but revolve around three major themes: 1) oxidant-stress induced tissue injury and cancer, 2) DNA damage, repair and mutagenesis and 3) hormonal regulation of gene expression. We intend to use this instrument for the high-throughput real-time quantitative analysis of RNA transcripts and DNA targets in biological samples and in detection of single nucleotide polymorphisms (SNP) in genes important in cancer. As indicated in the research projects from each investigator, the availability of the proposed instrument will significantly improve the scope and timeliness of their studies. Most importantly, it will allow the science to determine the pursuit of exciting discoveries in their funded research projects, rather than availability of current instruments. The overall goals of this shared multidisciplinary research facility are to use this advanced technology resource to carry out cutting-edge research that characterizes today's biomedical research and to train our doctoral students and postdoctoral fellows in the use of these modern methods that will enable them to develop into successful independent investigators. The research problems addressed by our investigators are highly relevant to major public health problems related to cancer, both in the mechanisms of tumor formation, the reasons for (lack of) effectiveness of cancer chemotherapeutic drugs, and the regulation of genes by hormones that are important in women's health.
