Regulation of DNA Repair Mechanisms: How the Chromatin Environment Regulates the DNA Damage Response

Open access
Stadler, Jens, Richly, Holger·2017·International Journal of Molecular Sciences

Abstract

Cellular DNA is constantly challenged by damage-inducing factors derived from exogenous or endogenous sources. In order to maintain genome stability and integrity, cells have evolved a wide variety of DNA repair pathways which counteract different types of DNA lesions, also referred to as the DNA damage response (DDR). However, DNA in eukaryotes is highly organized and compacted into chromatin representing major constraints for all cellular pathways, including DNA repair pathways, which require DNA as their substrate. Therefore, the chromatin configuration surrounding the lesion site undergoes dramatic remodeling to facilitate access of DNA repair factors and subsequent removal of the DNA lesion. In this review, we focus on the question of how the cellular DNA repair pathways overcome the chromatin barrier, how the chromatin environment is rearranged to facilitate efficient DNA repair, which proteins mediate this re-organization process and, consequently, how the altered chromatin landscape is involved in the regulation of DNA damage responses.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
