项目摘要

A cell is a highly complex system with distributed molecular physiologies in structured sub- cellular compartments whose interplay with the nuclear genome determine the functional characteristics of the cell. A classic example of distributed genomic processes is found in neurons. Learning and memory requires modulation of individual synapses through RNA localization, localized translation, and localized metabolites such as those from dendritic mitochondria. Dendrites of neurons integrate distributed synaptic signals into both electrical and nuclear transcriptional response. Dysfunction of these distributed genomic functions in neurons can result in a broad spectrum of neuropsychiatric diseases such as bipolar and depressive disorders, autism, among others. Understanding complex genomic interactions within a single cell requires new technologies: we need nano-scale ability to make genome-wide measurements at highly localized compartments and to effect highly localized functional genomic manipulations, especially in live tissues. To address this need, we propose to establish a Center for Sub-Cellular Genomics using neurons as model systems. The center will develop new optical and nanotechnology approaches to isolate sub-cellular scale components for genomic, metabolomics, and lipidomic analyses. The center will also develop new mass spectrometry methods, molecular biology methods, and informatics models to create a platform technology for sub-cellular genomics.

细胞是一个高度复杂的系统，具有结构化子结构中的分布式分子生理学细胞区室与核基因组的相互作用决定了功能细胞的特征。分布式基因组过程的一个典型例子可以在神经元。学习和记忆需要通过 RNA 调节单个突触本地化、本地化翻译和本地化代谢物，例如来自树突的代谢物线粒体。神经元的树突将分布式突触信号整合为电信号和突触信号。核转录反应。神经元中这些分布式基因组功能的功能障碍可能导致广泛的神经精神疾病，例如躁郁症和抑郁症疾病、自闭症等。了解单个细胞内复杂的基因组相互作用需要新技术：我们需要纳米级的能力在高度局部化的区室中进行全基因组测量并实现高度局部化的功能基因组操作，特别是在活组织中。到为了满足这一需求，我们建议建立一个使用神经元的亚细胞基因组学中心作为模型系统。该中心将开发新的光学和纳米技术方法分离亚细胞级成分用于基因组、代谢组学和脂质组学分析。这中心还将开发新的质谱方法、分子生物学方法和信息学模型为亚细胞基因组学创建平台技术。
