PROJECT SUMMARY (See instructions): The Proteomics, Metabolomics, and Lipidomics Core will be located at Pacific Northwest National Laboratory (PNNL). PNNL OMICs Core measurements will be based upon world-class mass spectrometry (MS)-based platforms and the availability of unique capabilities and resources. Ultra-sensitive proteomics analyses will be performed using the accurate mass and time (AMT) tag approach together with high resolution mass spectrometry, a process that offers high OMIC coverage, high quantitative precision, and high sensitivity with small sample-size requirements. Quantification of global phosphopeptide measurements will be obtained using ITRAQ stable isotope labeling. The global metabolomics and lipidomics components of this Core will utilize GC-MS and LC-MS, respectively. These studies will enhance our understanding of the host response to infection by evaluating changes in the abundance for the broad range of host proteins, metabolites, and lipid molecules that directly carry out biological functions. Based on the results of complementary transcriptomics (analyzed in parallel outside of this Core) and global MS-based OMICs data or a priori knowledge of the biological systems under study, we will also then employ multiplexed targeted MS-based analyses for quantifying a defined number of substrates and/or products of corresponding encoded proteins. These targeted proteomics, metabolomics and lipidomics analyses will provide accurate absolute quantification based on stable-isotope dilution where feasible

项目摘要（请参阅说明）：蛋白质组学，代谢组学和脂肪组学核心将位于太平洋西北国家实验室（PNNL）。 PNNL OMICS核心测量将基于世界一流的质谱（MS）平台以及独特的功能和资源的可用性。超敏感的蛋白质组学分析将使用准确的质量和时间（AMT）标签方法以及高分辨率质谱法，该过程提供高度覆盖，高定量精度和高灵敏度，并具有较小的样品大小要求。使用ITRAQ稳定同位素标记将获得全局磷酸肽测量的定量。该核心的全球代谢组学和脂质组学成分将分别使用GC-MS和LC-MS。这些研究将通过评估直接执行生物学功能的广泛宿主蛋白，代谢产物和脂质分子的丰度变化来增强我们对宿主对感染的反应的理解。基于互补转录组学（该核心之外的并联分析）和基于全球MS的OMICS数据或研究所研究的生物系统的先验知识，我们还将采用基于多重的目标MS分析来量化确定数量的底物和/或相应编码蛋白的底物和/或产物。这些靶向蛋白质组学，代谢组学和脂质组学分析将基于稳定 - 异位稀释液提供准确的绝对定量，其中可行
