Three-dimensional (3D) genomics is an emerging discipline that studies the 3D spatial structure and function of genomes, focusing on the 3D spatial conformation of genome sequences in the nucleus and its biological effects on biological processes such as DNA replication, DNA recombination and gene expression regulation. The invention of chromosome conformation capture (3C) technology speeds up the research on 3D genomics and its related fields. Furthermore, the development of 3C-based technologies, such as the genome-wide chromosome conformation capture (Hi-C) and chromatin interaction analysis using paired-end tag sequencing (ChIA-PET), help scientists get insight into the 3D genomes of various species. Aims of 3D genomics are to reveal the spatial genome organization, chromosomal interaction patterns, mechanisms underlying the transcriptional regulation and formation of biological traits of microorganism, plant, animal. Additionally, the identification of key genes and signaling pathways associated with biological processes and disease via chromosome 3C technology boosts the rapid development of agricultural science, life science and medical science. This paper reviews the research progress of 3D genomics, mainly in the concept of 3D genomics, the development of chromosome 3C technologies and their applications in agricultural science, life science and medical science, specifically in the field of tumor.
三维(3D)基因组学是一门新兴学科,研究基因组的三维空间结构和功能,重点关注基因组序列在细胞核中的三维空间构象及其对DNA复制、DNA重组和基因表达调控等生物学过程的生物学效应。染色体构象捕获(3C)技术的发明加速了对三维基因组学及其相关领域的研究。此外,基于3C的技术,如全基因组染色体构象捕获(Hi-C)和使用双末端标签测序的染色质相互作用分析(ChIA-PET)的发展,帮助科学家深入了解各种物种的三维基因组。三维基因组学的目标是揭示微生物、植物、动物的空间基因组组织、染色体相互作用模式、转录调控机制以及生物性状的形成。此外,通过染色体3C技术鉴定与生物学过程和疾病相关的关键基因和信号通路,推动了农业科学、生命科学和医学的快速发展。本文综述了三维基因组学的研究进展,主要包括三维基因组学的概念、染色体3C技术的发展及其在农业科学、生命科学和医学,特别是肿瘤领域的应用。
