DNA damage tolerance, mismatch repair and genome instability

Karran, P., Bignami, M.·1994·BioEssays

Abstract

DNA mismatch repair is an important pathway of mutation avoidance. It also contributes to the cytotoxic effects of some kinds of DNA damage, and cells defective in mismatch repair are resistant, or tolerant, to the presence of some normally cytotoxic base analogues in their DNA. The absence of a particular mismatch binding function from some mammalian cells confers resistance to the base analogues O 6‐methylguanine and 6‐thioguanine in DNA. Cells also acquire a spontaneous mutator phenotype as a consequence of this defect. Impaired mismatch binding can cause an instability in DNA microsatellite regions that comprise repeated dinucleotides. Microsatellite DNA instability is common in familial and sporadic colon carcinomas as well as in a number of other tumours. Several independent lines of investigation have identified defects in mismatch repair proteins that are causally related to these cancers.

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.
