项目摘要
PROJECT SUMMARY/ABSTRACT
Understanding the tumor microenvironment (TME) heterogeneity and architecture are key to stratify cancer
patients responsive to immunotherapy and clinical outcome. Single-cell RNA sequencing (scRNAseq) is a
powerful tool for studying the TME at the single-cell level, however, spatial information between single cells
was not preserved in this technology, which is vital in studying the TME. In contrast, use of spatially resolved
transcriptomics holds the promise in the understanding of the spatial contexture of the TME because of its
power to capture the location of individual cells within the larger tissue architecture. Recently,
commercialization of spatial transcriptomic (ST) technologies have allowed researchers to study at an
unprecedented level the spatial architecture of the TME. Similar to other “omics” technologies, novel
computational tools are urgently needed to decipher and infer biological meaning for these high-dimensional
ST data. In addition to the need for methods for analyzing and visualizing ST data in its current form, there is
the need to develop methods for the future state of ST, whereby the level of cellular resolution is vastly
decreasing to the single cell level. Moreover, the application of multiple assays to one tissue sample is also
producing multiple modalities measured on the same sample (e.g., scRNAseq, image-based cytometry
methods such as multiplex immunofluorescence) which requires effective methods for data integration. Lastly,
many ST studies are completed on multiple samples simultaneous with the goal of correlating TME features
with clinical outcome, thus requiring computational tools to unravel the impact of the spatial architecture of the
TME on clinical response. In the proposed research, we will tackle these challenges by implementing state-of-
the-art statistical and computational methods that account for and leverage the spatial information present in
ST data to understanding the TME. We will develop innovative methods for assessing the TME’s composition
(Aim 1) and studying co-localization and spatial heterogeneity (Aim 2), along with hardening of the analytical
software, spatialGE, for the analysis and visualization of ST data (Aim 3). The statistical and bioinformatics
analytical approaches implemented in spatialGE will allow cancer researchers to easily leverage these
methods in their studies of the TME. These analytical methods, along with the developed software tools
(spatialGE R/Bioconductor package along with web-based software), will be established in collaboration with
clinical, translational, and basic science cancer investigators to ensure usability and interpretability of the
developed approaches.
项目总结/摘要
了解肿瘤微环境(TME)的异质性和结构是分层癌症的关键
对免疫疗法有反应的患者和临床结果。单细胞RNA测序(scRNAseq)是一种
在单细胞水平上研究TME的强大工具,然而,单细胞之间的空间信息
在这项技术中没有保存下来,这对研究TME至关重要。相反,使用空间分辨的
转录组学在理解TME的空间结构方面有希望,因为它
捕获单个细胞在较大组织结构中的位置的能力。最近,
空间转录组学(ST)技术的商业化使研究人员能够在一个
TME的空间架构达到前所未有的水平。与其他“组学”技术类似,
迫切需要计算工具来破译和推断这些高维的生物学意义,
ST数据。除了需要用于以其当前形式分析和可视化ST数据的方法之外,
需要为ST的未来状态开发方法,从而大大提高细胞分辨率水平,
降低到单个细胞水平。此外,对一个组织样品应用多个测定也是有利的。
产生在同一样本上测量的多个模态(例如,scRNAseq,基于图像的细胞术
方法如多重免疫荧光),这需要有效的数据整合方法。最后,
许多ST研究是在多个样本上同时完成的,目的是将TME特征相关联
临床结果,因此需要计算工具来解开空间结构的影响,
TME临床缓解。在拟议的研究中,我们将通过实施国家-
最先进的统计和计算方法,占和利用空间信息存在于
ST数据有助于理解TME。我们将开发评估TME组成的创新方法
(Aim 1)和研究共定位和空间异质性(目标2),沿着强化的分析
软件spatialGE,用于ST数据的分析和可视化(目标3)。统计和生物信息学
在spatialGE中实施的分析方法将使癌症研究人员能够轻松地利用这些
方法在他们的研究TME。这些分析方法,沿着开发的软件工具
(空间GE R/Bioconductor包沿着网络软件),将与
临床、转化和基础科学癌症研究人员,以确保
发展办法。
