TAILIEUCHUNG - Predicting double-strand DNA breaks using epigenome marks or DNA at kilobase resolution

Double-strand breaks (DSBs) result from the attack of both DNA strands by multiple sources, including radiation and chemicals. DSBs can cause the abnormal chromosomal rearrangements associated with cancer. Recent techniques allow the genome-wide mapping of DSBs at high resolution, enabling the comprehensive study of their origins. | Mourad et al. Genome Biology 2018 19 34 https s13059-018-1411-7 METHOD Open Access Predicting double-strand DNA breaks using epigenome marks or DNA at kilobase resolution Raphaël Mourad1 Krzysztof Ginalski2 Gaëlle Legube3 and Olivier Cuvier1 Abstract Double-strand breaks DSBs result from the attack of both DNA strands by multiple sources including radiation and chemicals. DSBs can cause the abnormal chromosomal rearrangements associated with cancer. Recent techniques allow the genome-wide mapping of DSBs at high resolution enabling the comprehensive study of their origins. However these techniques are costly and challenging. Hence we devise a computational approach to predict DSBs using the epigenomic and chromatin context for which public data are readily available from the ENCODE project. We achieve excellent prediction accuracy at high resolution. We identify chromatin accessibility activity and long-range contacts as the best predictors.
