DNA是如何在细胞核内三维组织的,以及它如何影响细胞获取、读取和解释遗传信息的方式,是细胞生物学中存在时间最长的问题之一。利用基于染色体构象捕获技术(如3C, 4C, 5C和Hi-C)的新开发的分子,基因组和计算方法,基因组的空间组织正在以前所未有的分辨率进行探索。解释越来越大的染色质相互作用数据集现在提出了新的挑战。在这里,我们描述了几种类型的统计和计算方法,最近已开发的分析染色质相互作用的数据。
How DNA is organized in three dimensions inside the cell nucleus and how that affects the ways in which cells access, read and interpret genetic information are among the longest standing questions in cell biology. Using newly developed molecular, genomic, and computational approaches based on the chromosome conformation capture technology (such as 3C, 4C, 5C and Hi-C) the spatial organization of genomes is being explored at unprecedented resolution. Interpreting the increasingly large chromatin interaction datasets is now posing novel challenges. Here we describe several types of statistical and computational approaches that have recently been developed to analyze chromatin interaction data.
