Genes Possessing the Most Frequent DNA DSBs Are Highly Associated with Development and Cancers, and Essentially Overlap with the rDNA-Contacting Genes. Int J Mol Sci 2022; 23:ijms23137201.

Abstract
Double-strand DNA breakes (DSBs) are the most deleterious and widespread examples of DNA damage. They inevitably originate from endogenous mechanisms in the course of transcription, replication, and recombination, as well as from different exogenous factors. If not properly repaired, DSBs result in cell death or diseases. Genome-wide analysis of DSBs has revealed the numerous endogenous DSBs in human chromosomes. However, until now, it has not been clear what kind of genes are preferentially subjected to breakage. We performed a genetic and epigenetic analysis of the most frequent DSBs in HEK293T cells. Here, we show that they predominantly occur in the active genes controlling differentiation, development, and morphogenesis. These genes are highly associated with cancers and other diseases. About one-third of the genes possessing frequent DSBs correspond to rDNA-contacting genes. Our data suggest that a specific set of active genes controlling morphogenesis are the main targets of DNA breakage in human cells, although there is a specific set of silent genes controlling metabolism that also are enriched in DSBs. We detected this enrichment by different activators and repressors of transcription at DSB target sites, as well breakage at promoters. We propose that both active transcription and silencing of genes give a propensity for DNA breakage. These results have implications for medicine and gene therapy.

Abstract
Mapping the genome-wide distribution of DNA lesions is key to understanding damage signalling and DNA repair in the context of genome and chromatin structure. Analytical tools based on high-throughput next-generation sequencing have revolutionized our progress with such investigations, and numerous methods are now available for various base lesions and modifications as well as for DNA double-strand breaks. Considering that single-strand breaks are by far the most common type of lesion and arise not only from exposure to exogenous DNA-damaging agents, but also as obligatory intermediates of DNA replication, recombination and repair, it is surprising that our insight into their genome-wide patterns, that is the 'SSBreakome', has remained rather obscure until recently, due to a lack of suitable mapping technology. Here we briefly review classical methods for analysing single-strand breaks and discuss and compare in detail a series of recently developed high-resolution approaches for the genome-wide mapping of these lesions, their advantages and limitations and how they have already provided valuable insight into the impact of this type of damage on the genome.

Abstract
Constitutional biological processes involve the generation of DNA double-strand breaks (DSBs). The production of such breaks and their subsequent resolution are also highly relevant to neurodegenerative diseases and cancer, in which extensive DNA fragmentation has been described Stephens et al. (2011), Blondet et al. (2001). Tchurikov et al. Tchurikov et al. (2011, 2013) have reported previously that frequent sites of DSBs occur in chromosomal domains involved in the co-ordinated expression of genes. This group report that hot spots of DSBs in human HEK293T cells often coincide with H3K4me3 marks, associated with active transcription Kravatsky et al. (2015) and that frequent sites of DNA double-strand breakage are likely to be relevant to cancer genomics Tchurikov et al. (2013, 2016) . Recently, they applied a RAFT (rapid amplification of forum termini) protocol that selects for blunt-ended DSB sites and mapped these to the human genome within defined co-ordinate ‘windows’. In this paper, we re-analyse public RAFT data to derive sites of DSBs at the single-nucleotide level across the built genome for human HEK293T cells (https://figshare.com/s/35220b2b79eaaaf64ed8). This refined mapping, combined with accessory ENCODE data tracks and ribosomal DNA-related sequence annotations, will likely be of value for the design of clinically relevant targeted assays such as those for cancer susceptibility, diagnosis, treatment-matching and prognostication.

Abstract
DNA breakage arises during a variety of biological processes, including transcription, replication and genome rearrangements. In the context of disease, extensive fragmentation of DNA has been described in cancer cells and during early stages of neurodegeneration (Stephens et al., 2011 Stephens et al. (2011) [5]; Blondet et al., 2001 Blondet et al. (2001) [1]). Stults et al. (2009) Stults et al. (2009) [6] reported that human rDNA gene clusters are hotspots for recombination and that rDNA restructuring is among the most common chromosomal alterations in adult solid tumours. As such, analysis of rDNA regions is likely to have significant prognostic and predictive value, clinically. Tchurikov et al. (2015a, 2016) Tchurikov et al. (2015a, 2016) [7], [9] have made major advances in this direction, reporting that sites of human genome double-strand breaks (DSBs) occur frequently at sites in rDNA that are tightly linked with active transcription - the authors used a RAFT (rapid amplification of forum termini) protocol that selects for blunt-ended sites. They reported the relative frequency of these rDNA DSBs within defined co-ordinate ‘windows’ of varying size and made these data (as well as the relevant ‘raw’ sequencing information) available to the public (Tchurikov et al., 2015b). Assay designs targeting rDNA DSB hotspots will benefit greatly from the publication of break sites at greater resolution. Here, we re-analyse public RAFT data and make available rDNA DSB co-ordinates to the single-nucleotide level.

Abstract
Endogenous hot spots of DNA double-strand breaks (DSBs) are tightly linked with transcription patterns and cancer genomics(1,2). There are nine hot spots of DSBs located in human rDNA units(3-6). Here we describe that the profiles of these hot spots coincide with the profiles of γ-H2AX or H2AX, strongly suggesting a high level of in vivo breakage inside rDNA genes. The data were confirmed by microscopic observation of the largest γ-H2AX foci inside nucleoli in interphase chromosomes. In metaphase chromosomes, we observed that only some portion of rDNA clusters possess γ-H2AX foci and that all γ-H2AX foci co-localize with UBF-1 binding sites, which strongly suggests that only active rDNA units possess the hot spots of DSBs. Both γ-H2AX and UBF-1 are epigenetically inherited and thus indicate the rDNA units that were active in the previous cell cycle. These results have implications for diverse fields, including epigenetics and cancer genomics.

Genome-wide mapping of hot spots of DNA double-strand breaks in human cells as a tool for epigenetic studies and cancer genomics. GENOMICS DATA 2015; 5:89-93.

Abstract
Hot spots of DNA double-strand breaks (DSBs) are associated with coordinated expression of genes in chromosomal domains (Tchurikov et al., 2011 [1]; 2013). These 50–150-kb DNA domains (denoted “forum domains”) can be visualized by separation of undigested chromosomal DNA in pulsed-field agarose gels (Tchurikov et al., 1988; 1992) and used for genome-wide mapping of the DSBs that produce them. Recently, we described nine hot spots of DSBs in human rDNA genes and observed that, in rDNA units, the hot spots coincide with CTCF binding sites and H3K4me3 marks (Tchurikov et al., 2014), suggesting a role for DSBs in active transcription. Here we have used Illumina sequencing to map DSBs in chromosomes of human HEK293T cells, and describe in detail the experimental design and bioinformatics analysis of the data deposited in the Gene Expression Omnibus with accession number GSE53811 and associated with the study published in DNA Research (Kravatsky et al., 2015). Our data indicate that H3K4me3 marks often coincide with hot spots of DSBs in HEK293T cells and that the mapping of these hot spots is important for cancer genomic studies.
