Abstract
Advances in "omics" technology have made it possible to study a wide range of cellular phenomena at the single-cell level. Recently, we developed single-cell DNA replication sequencing (scRepli-seq) that measures replication timing (RT) by copy number differences between replicated and unreplicated genomic DNA in replicating single mammalian cells. This method has been used to reveal previously unrecognized static and dynamic natures of several hundred kilobases to a few megabases-scale chromosomal units called RT domains. Because RT domains are highly correlated to A/B compartments detected by Hi-C, scRepli-seq data can be used to predict the 3D organization of the genome in the nuclear space. scRepli-seq, which essentially measures the copy number, can also be applied to study genome instability.
期刊介绍:
During the last decades, ''Cytogenetic and Genome Research'' has been the leading forum for original reports and reviews in human and animal cytogenetics, including molecular, clinical and comparative cytogenetics. In recent years, most of its papers have centered on genome research, including gene cloning and sequencing, gene mapping, gene regulation and expression, cancer genetics, comparative genetics, gene linkage and related areas. The journal also publishes key papers on chromosome aberrations in somatic, meiotic and malignant cells. Its scope has expanded to include studies on invertebrate and plant cytogenetics and genomics. Also featured are the vast majority of the reports of the International Workshops on Human Chromosome Mapping, the reports of international human and animal chromosome nomenclature committees, and proceedings of the American and European cytogenetic conferences and other events. In addition to regular issues, the journal has been publishing since 2002 a series of topical issues on a broad variety of themes from cytogenetic and genome research.
