DESCRIPTION (provided by applicant): The Cancer Genome Atlas (TCGA) initiative, by generating comprehensive genomic characterization of diverse human cancers, poses the critical question of how genomic variation translates to cancer. Genomic abnormalities are thought to drive cancer phenotypes through their effects on proteins and proteomes, which can be analyzed by systematic application of new proteomic technologies. The National Cancer Institute (NCI) Clinical Proteomic Technology Assessment for Cancer (CPTAC) initiative has implemented standardized technology platforms in a biomarker development pipeline and, as one of the initial 5 CPTAC programs, we have made a major contribution to this effort. We have already pioneered this pipeline for cancer biomarker development through the Jim Ayers Institute for Precancer Detection and Diagnosis, a unique initiative established in the Vanderbilt-lngram Cancer Center. This application proposes the Vanderbilt Proteome Characterization Center (Vanderbilt PCC) built on the expertise and infrastructure of the Ayers Institute. The overall goal of the Vanderbilt PCC is to integrate genomic information with proteomic technologies to discover and verify protein biomarkers for cancer. To analyze genomically characterized tumor tissue biospecimens from the TCGA program, we will apply standardized liquid chromatography-tandem mass spectrometry (LC-MS/MS) and liquid chromatography-multiple reaction monitoring mass spectrometry (LC-MRM-MS) platforms. These analyses will encompass global protein expression changes and changes in phosphorylated and acetylated proteins that regulate signaling networks in cancer. The Vanderbilt PCC will integrate TCGA-derived genomic data and other relevant information into the discovery process and develop systematic approaches to prioritize biomarker candidates. We will verify biomarker candidates in clinically relevant cohorts with standardized, targeted analyses. We will also advance technologies for assessment of signaling networks and functional subproteomes, the integration of genomic and proteomic data and the evaluation of analytical system performance. The Vanderbilt PCC brings to the CPTC network a fully integrated program with expertise in all of the critical areas specified by the RFA.

描述（由申请人提供）：癌症基因组图谱（TCGA）计划，通过生成各种人类癌症的全面基因组特征，提出了基因组变异如何转化为癌症的关键问题。基因组异常被认为是通过其对蛋白质和蛋白质组的影响来驱动癌症表型的，这可以通过系统应用新的蛋白质组学技术来分析。美国国家癌症研究所（NCI）癌症临床蛋白质组学技术评估（CPTAC）计划已经在生物标志物开发管道中实施了标准化技术平台，作为最初的5个CPTAC项目之一，我们对此做出了重大贡献。我们已经通过吉姆艾尔斯癌症前检测和诊断研究所开创了这种癌症生物标志物开发的管道，这是范德比尔特-英格拉姆癌症中心建立的一项独特倡议。本应用程序提出建立在艾尔斯研究所的专业知识和基础设施上的范德比尔特蛋白质组表征中心（Vanderbilt PCC）。范德比尔特PCC的总体目标是将基因组信息与蛋白质组学技术相结合，以发现和验证癌症的蛋白质生物标志物。为了分析来自TCGA项目的基因组特征肿瘤组织生物标本，我们将应用标准化的液相色谱-串联质谱（LC-MS/MS）和液相色谱-多重反应监测质谱（LC-MRM-MS）平台。这些分析将包括调节癌症信号网络的全球蛋白表达变化以及磷酸化和乙酰化蛋白的变化。Vanderbilt PCC将把tcga衍生的基因组数据和其他相关信息整合到发现过程中，并开发系统的方法来优先考虑候选生物标志物。我们将通过标准化的、有针对性的分析，在临床相关队列中验证候选生物标志物。我们还将推进信号网络和功能亚蛋白质组的评估技术，基因组和蛋白质组数据的整合以及分析系统性能的评估。范德比尔特PCC为CPTC网络带来了一个完全集成的程序，具有RFA指定的所有关键领域的专业知识。
