项目摘要
ABSTRACT
Genome sequencing technology has been transformative in the analysis of cancer. From genomic,
transcriptomic, and epigenetic data, researchers are making new discoveries about the mechanisms of cancer
development that are leading to new therapies and diagnostic tests. Accelerating these discoveries, genomic
analysis is being applied to a wide variety of analytes such as cell-free DNA and single cells from tissue biopsies.
However, given the increasing range of available genomic sequencing assays available for cancer genomic
studies, a major challenge comes from the limited amounts of clinical tumor samples. Tissue biopsies and
samples oftentimes provide a small amount of genomic analyte. As a result, only one or two genomic sequencing
experiments can be performed, which leads to a less than complete picture of features of a patient tumor.
To address this issue, we developed and validated a technology called APEX – this sequencing technology
enables repeated use of the same nucleic acid analytes derived from a variety of clinical samples relevant for
cancer translational research and clinical studies. As a result, researchers have the opportunity to conduct many
types of genomic analyses on the same sample and genomic material. APEX technology is based on the
covalent attachment of nucleic acid analytes to a solid support, so that the original genomic material is
permanently retained, can be subject to a variety of sequencing assays and as a result, can be analyzed through
many iterations. The use of multiple iterations also offers an opportunity to improve the delineations of critical
genomic aberrations that occur in only a small fraction of the tumor cells. We propose the development of APEX
for integrated multi-modal and iterative genomic analyses of primary cancer biopsies and cell free DNA from
patients. Aim 1 focuses on cell-free DNA analytes, and Aim 2 focuses on single-cell transcriptome sequencing.
Overall, our proposed APEX technology will broadly impact the field of translational cancer research by
providing a new platform whereby clinical samples can be used as a renewable resource for subsequent genomic
sequencing. It removes constraints afforded by limited amounts of tissue samples from translational clinical
studies. With these improvements, APEX will improve the assessment of somatic genomic alterations in cancer
cells, integration of multi-modal sequencing technologies, and offer personalized molecular analyses for each
cancer patient.
抽象的
基因组测序技术在癌症分析中具有变革性。来自基因组,
转录组和表观遗传学数据,研究人员正在对癌症机制进行新的发现
导致新疗法和诊断测试的开发。加速这些发现,基因组
分析应用于多种分析物,例如无细胞的DNA和来自组织活检的单个细胞。
但是,鉴于可用于癌症基因组的可用基因组测序测定的增加范围
研究,一个主要挑战来自有限的临床肿瘤样本。组织活检和
接触的样本提供了少量的基因组分析物。结果,只有一个或两个基因组测序
可以进行实验,从而导致患者肿瘤特征的完整图像。
为了解决这个问题,我们开发并验证了一种称为APEX的技术 - 该测序技术
能够重复使用从与
癌症翻译研究和临床研究。结果,研究人员有机会进行许多
同一样品和基因组材料的基因组分析类型。 Apex技术基于
核酸分析物与固体支持的共价附着,因此原始基因组材料是
永久保留,可以接受各种测序测定,因此可以通过
许多迭代。多次迭代的使用还提供了一个机会来改善关键的描述
仅在一小部分肿瘤细胞中发生的基因组像差。我们提出了顶点的发展
用于原代癌症活检和无细胞DNA的综合多模式和迭代基因组分析
患者。 AIM 1专注于无细胞DNA分析,AIM 2专注于单细胞转录组测序。
总体而言,我们提出的APEX技术将广泛影响转化癌研究领域
提供一个新平台,临床样本可以用作可再生资源的后续基因组资源
测序。 它消除了来自翻译的临床的有限的组织样品所提供的限制
研究。通过这些改进,Apex将改善癌症体细胞基因组改变的评估
单元格,多模式测序技术的整合,并为每种分子提供个性化分析
癌症患者。
