Role of DNA Mismatch Repair Defects in the Pathogenesis of Human Cancer

Peltomäki, Päivi·2003·Journal of Clinical Oncology

Abstract

The DNA mismatch repair (MMR) system is necessary for the maintenance of genomic stability. In a broad sense, all main functions of the MMR system, including the correction of biosynthetic errors, DNA damage surveillance, and prevention of recombination between nonidentical sequences serve this important purpose. Failure to accomplish these functions may lead to cancer. It is therefore not surprising that inherited defects in the MMR system underlie one of the most prevalent cancer syndromes in humans, hereditary nonpolyposis colon cancer (HNPCC). In addition, acquired defects of the same system may account for 15% to 25%, or even a higher percentage, of sporadic cancers of different organs of the “HNPCC spectrum,” including the colon and rectum, uterine endometrium, stomach, and ovaries. Recent studies indicate that the MMR genes may be involved in the pathogenesis of even a broader spectrum of tumors in one way or another. An updated review of the different features of the human MMR system will be provided, with the emphasis on their implications in cancer development.

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.
