Enzymatic Processing of Radiation-Induced Free Radical Damage in DNA

Wallace, Susan S.·1998·Radiation Research

Abstract

A significant fraction of DNA damage produced by ionizing radiation comes from free radicals generated during the radiolysis of water, that is, by indirect effects. The hydroxyl radical, the principal damaging species, produces single-strand breaks and a plethora of base and sugar lesions that can be cytotoxic or mutagenic. Free radical-induced DNA damage is repaired by an efficient and ubiquitous process called "base excision repair" which is composed of either three or four enzymatic steps, depending on the initial lesion. The result is an intact DNA molecule with a short repair patch size. If, however, multiply damaged sites similar to those produced by ionizing radiation are processed by base excision repair, a double-strand break can result if the opposing lesions are more than three nucleotides apart. Because base excision repair evolved to protect the genome from endogenous damages, the proteins involved are highly conserved from bacteria to humans, not only at the functional level, but at the level of amino acid sequence.

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.
