染色体构象捕获技术在造血分化调控研究中的进展

Unraveling the Chromosome Higher-order Structures in the Transcriptional Regulation of Hematopoiesis by Chromosome Conformation Capture——Editorial

最新研究显示基因组空间结构对转录调控起着关键的作用。以造血分化过程为例,三维调控网络能更真实、精确地呈现造血特异的关键转录因子调控的组织方式和动态过程。革新的染色体构象捕获技术的发展和延伸为解析不同染色体间的调控元件、同一染色体内的不同调控元件以及核内染色质功能性组分之间的转录调控的空间结构提供了研究手段。本文详细介绍了染色体构象捕获技术和在此基础上衍生的高通量组学技术的发展,以及这些技术在造血分化过程中的应用。

Emerging evidence has demonstrated that genomes are organized into higher-order structures in vivo and long range interactions between genornic regions largely contribute to the regulation of gene expression. Hematopoiesis, orchestrated by the precise spatial regulation and organization of hematopoietic transcription factors, serves as a good model for exploring these issues. The chromosome conformation capture （3C） methodology and its high throughput based technology provide an innovative solution for analyzing the regulation of functional elements through inter- chromosomal and intra-chromosomal interactions, and contacts of functional components in nuclei, thus leading to a more comprehensive understanding of human genome and gene expression. This review focuses on the recent progress of 3C and its derivatives, and their applications in unraveling the mechanisms of transcriptional regulation in hematopoiesis.
