DESCRIPTION (provided by applicant): We are seeking support to establish a Genome Characterization Center, as a part of the Cancer Genome Atlas Project in Boston. The goal of the proposed effort is to analyze 2,000-2,500 tumor samples each year over a five-year period of time and identify a set of genes that can be resequenced by the members of The Cancer Genome Atlas (TCGA) project. It is well established that regions of the cancer genome that are amplified or show loss of heterozygosity or deletion harbor genes that are important for tumor initiation and progression. We will initially identify such regions in the cancer genome by conducting array comparative genomic hybridization (aCGH). Based upon detailed comparisons of many different platforms we have chosen to use the high-density Agilent oligonucleotide arrays for our studies. We have used the Agilent platform to characterize several hundreds of tumors and their corresponding controls, much of it a part of the current TCGA project. We already have the ability to have a throughput of processing four to five thousand samples during the first year of the proposed grant. During the first year we propose to use a sequencing based approach to determine copy number changes in tumors. In the initial phase we will examine 200 samples by a sequence tag counting approach and compare the results with the Agilent and other platforms. Based upon our experience we anticipate that this is eminently feasible and we will gradually switch the copy number analysis to the sequence based platform. In the second year 40% of the samples will be processed by the sequencing platform and the remaining 60% by the array platform. In year three 60% of the samples will be processed by sequencing and in years 4 and 5 we plan to completely switch to the sequencing approach. We have a well established pipeline to collect, store, retrieve and analyze the data from these two platforms. We will develop Level 1-4 data as defined by the consortium and deposit these data in a timely fashion in the Data Coordinating Center. We also propose to use powerful informatics tools that we have developed and propose to improve to analyze the aCGH and the sequence based data and extract a list of most interesting genes for resequencing. We have established an award winning IT infrastructure that will be deployed for LIMS, data storage, data retrieval, data analysis and interface with caBIG. Our proposed approach also has the ability to generate additional useful data for tumor and patient stratification.

描述（由申请人提供）：我们正在寻求支持建立一个基因组表征中心，作为波士顿癌症基因组图谱项目的一部分。这项计划的目标是在五年的时间里，每年分析2000 - 2500个肿瘤样本，并确定一组基因，这些基因可以被癌症基因组图谱（TCGA）项目的成员重新测序。已经确定的是，癌症基因组中被扩增或显示杂合性缺失或缺失的区域包含对肿瘤的发生和发展至关重要的基因。我们将通过进行阵列比较基因组杂交（aCGH）来初步确定癌症基因组中的这些区域。基于许多不同平台的详细比较，我们选择使用高密度安捷伦寡核苷酸阵列进行我们的研究。我们已经使用Agilent平台对数百种肿瘤及其相应的对照进行了表征，其中大部分是当前TCGA项目的一部分。我们已经有能力在拟议拨款的第一年处理4000到5000个样品。在第一年，我们建议使用基于测序的方法来确定肿瘤中拷贝数的变化。在初始阶段，我们将通过序列标签计数方法检查200个样本，并将结果与Agilent和其他平台进行比较。根据我们的经验，我们预计这是非常可行的，我们将逐渐将拷贝数分析切换到基于序列的平台。第二年，40%的样品将由测序平台处理，剩下的60%将由阵列平台处理。在第三年，60%的样品将通过测序处理，在第4年和第5年，我们计划完全切换到测序方法。我们有一个完善的管道来收集、存储、检索和分析来自这两个平台的数据。我们将开发由联盟定义的1-4级数据，并及时将这些数据存入数据协调中心。我们还建议使用我们已经开发并建议改进的强大信息学工具来分析aCGH和基于序列的数据，并提取最有趣的基因列表进行重测序。我们已经建立了一个屡获殊荣的IT基础设施，将用于LIMS，数据存储，数据检索，数据分析以及与caBIG的接口。我们提出的方法还能够为肿瘤和患者分层产生额外的有用数据。
