项目摘要

Abstract: Technical batch effects pose a fundamental challenge to quality control and reproducibility of even single-laboratory research projects, but the possibilities for serious error are greatly magnified in complex, multi-institutional enterprises such as the cancer molecular profiling projects being undertaken by the NCI Center for Cancer Genomics (CCG). To aid in detection, quantitation, interpretation, and (when appropriate) correction for technical batch effects in such data, we have developed the MBatch computational tool and web portal. MBatch has become indispensible for quality-control “surveillance” of data in The Cancer Genome Atlas (TCGA) project, but detecting and quantitating batch effects (or trend effects or statistical outliers) are just the first steps in a process. The next steps involve detective work in collaboration with those who generated the data, drawing upon expertise in integrative analysis across data types, pathways, and systems-level biology. That detective work usually succeeds in diagnosing the cause of a batch effect as technical or biological. If technical, then computational correction can be done (judiciously). The primary aim of the proposed Genome Data Analysis Center (GDAC) is to translate that successful quality-control model from TCGA to other current and future large-scale molecular profiling projects sponsored by the CCG. We will be ready to do that on Day 1. The second aim is to increase the power of MBatch to perform the basic quality-control functions. We will add a number of innovative new algorithms (Replicates- Based Normalization, Empirical Bayes++, and CorNet) and increase the repertoire of standard methods. We will also add major visualization resources including our interactive Next-Generation Clustered Heat Maps. The third aim is to make the system sufficiently robust, user-friendly, interactive, carefully documented, and easy to install that bench biologists and clinical researchers can use it to explore CCG-generated data or their own. Toward those ends, we have established collaborations to implement MBatch in Galaxy and on the cloud. We bring a number of assets to the proposed GDAC, including (i) multidisciplinary expertise in bioinformatics, biostatistics, software engineering, biology, and clinical oncology; PIs with a combined 21 years of experience in high-throughput molecular profiling studies of clinical cancers (in a highly consortial context); international leadership in batch effects analysis; a highly professional software engineering team with a track record of producing high-end, highly visual bioinformatics packages and websites; a team of 20 Analysts whose expertise can be called on; extensive computing resources, including one of the most powerful academically- based machines in the world; strong institutional support; close working relationships with first-class basic, translational, and clinical researchers throughout MD Anderson, one of the foremost cancer centers in the country. The bottom-line mission of the GDAC will be aid the research community's effort to understand cancer and to prevent, detect, diagnose, and treat it more effectively for the benefit of patients and their families.

MBatch已经成为癌症基因组图谱数据质量控制“监测”的不可或缺的工具 (TCGA)项目,但检测和定量批次效应(或趋势效应或统计离群值)只是 一个过程中的第一步。接下来的步骤涉及与那些生成 数据,利用跨数据类型,途径和系统级生物学的综合分析专业知识。 这种检测工作通常能成功地诊断出批量效应的原因是技术上的还是生物上的。如果 技术,然后计算校正可以做(明智地)。 拟议中的基因组数据分析中心(GDAC)的主要目的是将成功的 质量控制模型从TCGA到其他当前和未来的大规模分子分析项目赞助 在CCG。我们将在第一天做好准备。第二个目标是增加MBatch的功能, 履行基本的质量控制职能。我们将增加一些创新的新算法(复制- 基于标准化、经验贝叶斯++和CorNet)并增加标准方法的库。我们 还将添加主要的可视化资源,包括我们的交互式下一代加密热图。的 第三个目标是使系统足够强大、用户友好、交互式、仔细记录并且易于使用 生物学家和临床研究人员可以使用它来探索CCG生成数据或他们自己的数据。 为了实现这些目标,我们已经建立了合作关系,在Galaxy和云上实施MBatch。 我们为拟议中的GDAC带来了许多资产,包括(i)生物信息学方面的多学科专业知识, 生物统计学、软件工程、生物学和临床肿瘤学;具有21年经验的PI 临床癌症的高通量分子分析研究(在高度联合的背景下);国际 在批量效应分析方面的领导地位;一个高度专业的软件工程团队, 生产高端,高度可视化的生物信息学软件包和网站;一个由20名分析师组成的团队, 可以调用专业知识;广泛的计算资源,包括最强大的学术之一- 世界上最先进的机器;强大的机构支持;与一流的基础, 翻译和临床研究人员在MD安德森,在最重要的癌症中心之一, 国家GDAC的底线使命是帮助研究团体了解癌症 并更有效地预防、检测、诊断和治疗,造福患者及其家属。
