New insights into the roles of ATM and DNA-PKcs in the cellular response to oxidative stress

Abstract

Reactive oxygen species (ROS) are induced by a variety of endogenous and exogenous sources. At pathologically high levels, ROS cause damage to biological molecules, including DNA. The damage sustained by DNA likely plays a key role in the pathogenesis of aging and carcinogenesis. Extensive research has established in detail the mechanism of cellular response to oxidative stress. Attention is now focused on identifying the molecular contributions of the key DNA damage response kinases ataxia telangiectasia mutated (ATM), DNA-dependent protein kinase catalytic subunit (DNA-PKcs), and ATM- and Rad3-related (ATR) in the oxidative stress response. In this review, we will provide an update of the current evidence regarding the involvement of these related DNA damage response kinases in oxidative DNA lesion repair and signaling responses. The growing understanding of the involvement of ATM, DNA-PKcs, and ATR in the oxidative stress response will offer new possibilities for the treatment of ROS-related diseases.

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.
