哺乳动物基因组以其线性序列编码遗传信息,但其基因的适当表达需要染色体折叠成复杂的三维结构。转录控制涉及在基因和调控元件之间建立物理连接,既包括染色体之间的连接,也包括染色体沿着的连接。最近在探测染色体折叠方面的技术创新为基因组的空间组织及其在基因调控中的作用提供了新的见解。正在出现的是,大型复杂染色体的折叠涉及结构层次,从连接基因和增强子的染色质环到更大的染色体结构域和核隔室。这些结构沿着这个层次沿着越大,它们在细胞内就越稳定,而在细胞之间就变得更加随机。在这里,我们回顾了这个层次结构的实验和理论数据,并提出了最近发现的拓扑关联域的关键作用。
Mammalian genomes encode genetic information in their linear sequence, but appropriate expression of their genes requires chromosomes to fold into complex three-dimensional structures. Transcriptional control involves the establishment of physical connections among genes and regulatory elements, both along and between chromosomes. Recent technological innovations in probing the folding of chromosomes are providing new insights into the spatial organization of genomes and its role in gene regulation. It is emerging that folding of large complex chromosomes involves a hierarchy of structures, from chromatin loops that connect genes and enhancers to larger chromosomal domains and nuclear compartments. The larger these structures are along this hierarchy, the more stable they are within cells, while becoming more stochastic between cells. Here, we review the experimental and theoretical data on this hierarchy of structures, and propose a key role for the recently discovered Topologically Associating domains.
