项目摘要

PROJECT SUMMARY Precision medicine in cancer, a disease of the genome, relies on a deep and comprehensive understanding of the genetic mutations and abnormalities that accumulate in normal cells and drive transformation to cancer. The Getz and Rheinbay Labs have expertise in the discovery and characterization of point mutations through rigorous cancer genome analysis. In this proposal, we aim to create a Genome Data Analysis Center (GDAC) focused on employing our existing tools to robustly and comprehensively characterize point mutations (single-nucleotide variations and small indels) across the entire cancer genome to address scientific questions related to biological underpinnings of cancer that arise in each project we are assigned. We also have the flexibility to adapt our tools as deemed necessary by the unique needs of each project. Specifically, we plan to integrate and characterize mutations, mutational signatures, and other data types to comprehensively discover cancer drivers in coding and non-coding regions of the genome, including the often ignored more difficult-to-analyze regions of the genome. We will do this by incorporating methods to determine DNA methylation signatures as well as by interrogating the epigenome in both coding and non-coding regions of the genome. We further plan to advance our ability to determine trajectories of tumor evolution and heterogeneity by adapting our PhylogicNDT suite of tools to analyze the evolution, subclonal heterogeneity, and timing and order of mutational events from multiple samples (e.g., samples acquired longitudinally or spatially) from the same patient, or even from cell-free DNA (cfDNA) from non-invasive blood biopsy. In the interest of advancing the GDC’s goal of improving personalized medicine, we teamed with expert clinicians and translational scientists, Dr. Keith Flaherty and Dr. Kirsten Kübler, that will interpret our findings, associate them with clinical data and direct them towards clinical impact. They will also enhance our tools for identifying the tissue- and cell-of-origin of cancers to not only better understand the underlying mechanisms of transformation in a particular cancer type or subtype but also provide more effective therapeutic targets. Moreover, our final Aim is to perform patient-specific analysis to improve and enable precision medicine, especially in patients whose tumors do not have any identified actionable driver events. Here, we will employ machine learning techniques to build predictive models of therapeutic vulnerabilities. Overall, we offer primary competencies in DNA point mutation characterization, analysis of cfDNA, and determination of mutational signatures to the GDAN. We also bring added value with secondary competencies in methylation analysis (in the context of mutational signatures), mRNA analysis, single-cell RNA sequencing, and pathway/integrative data analysis. Bringing our extensive expertise to the various newly assembled Analysis Working Groups and collaborating with other GDACs within the GDAN can help to answer outstanding questions in cancer with the ultimate goal of improving diagnosis, prognosis, and treatment for every cancer patient.
项目概要 癌症(一种基因组疾病)的精准医学依赖于对以下方面的深入而全面的理解: 在正常细胞中积累并导致转化为癌症的基因突变和异常。这 Getz 和 Rheinbay Labs 拥有通过严格的方法发现和表征点突变的专业知识。 癌症基因组分析。在本提案中,我们的目标是创建一个基因组数据分析中心(GDAC),重点关注 利用我们现有的工具来稳健、全面地表征点突变(单核苷酸 整个癌症基因组中的变异和小插入缺失),以解决与生物学相关的科学问题 我们分配的每个项目中出现的癌症的基础。我们还可以灵活地调整我们的工具 每个项目的独特需求认为有必要。具体来说,我们计划整合并表征 突变、突变特征和其他数据类型,以全面发现编码和癌症驱动因素 基因组的非编码区域,包括经常被忽视的基因组中更难分析的区域。 我们将通过结合确定 DNA 甲基化特征的方法以及询问 基因组编码区和非编码区的表观基因组。我们进一步计划提高我们的能力 通过调整我们的 PhylogicNDT 工具套件来确定肿瘤进化和异质性的轨迹 分析多个样本的进化、亚克隆异质性以及突变事件的时间和顺序 (例如,纵向或空间采集的样本)来自同一患者,甚至来自游离 DNA (cfDNA) 来自非侵入性血液活检。为了推进 GDC 改善个性化医疗的目标, 我们与专家临床医生和转化科学家 Keith Flaherty 博士和 Kirsten Kübler 博士合作, 解释我们的发现,将其与临床数据联系起来,并引导它们产生临床影响。他们还将 增强我们识别癌症组织和细胞起源的工具,不仅可以更好地了解癌症 特定癌症类型或亚型转化的潜在机制,而且还提供更有效的 治疗目标。此外,我们的最终目标是进行针对患者的分析,以改进和实现 精准医学,特别是对于肿瘤没有任何已识别的可操作驱动事件的患者。 在这里,我们将采用机器学习技术来构建治疗漏洞的预测模型。 总体而言,我们提供 DNA 点突变表征、cfDNA 分析和 确定 GDAN 的突变特征。我们还通过次要能力带来附加值 用于甲基化分析(突变特征)、mRNA 分析、单细胞 RNA 测序、 和路径/综合数据分析。将我们广泛的专业知识应用于各种新组装的分析中 工作组以及与 GDAN 内其他 GDAC 的合作有助于解决悬而未决的问题 癌症领域的最终目标是改善每位癌症患者的诊断、预后和治疗。
