WormBook, 2006 The integrity of the genome is essential to the health of the individual and to the reproductive success of a species. Transmission of genetic information is in a selective balance between two opposing forces, the maintenance of genetic stability versus elimination of mutational change and loss of evolutionary potential. Caenorhabditis elegans provides

Cellular and Molecular Life Sciences (CMLS), 2004 Stability of DNA largely depends on accuracy of repair mechanisms, which remove structural anomalies induced by exogenous and endogenous agents or introduced by DNA metabolism, such as replication. Most repair mechanisms include nucleolytic processing of DNA, where nucleases cleave a phosphodiester bond between a deoxyribose and a phosphate residue ...

Optimality in DNA repair [PDF]
Journal of Theoretical Biology, 2012 DNA within cells is subject to damage from various sources. Organisms have evolved a number of mechanisms to repair DNA damage. The activity of repair enzymes carries its own risk, however, because the repair of two nearby lesions may lead to the breakup of DNA and result in cell death.

Annual Review of Biochemistry, 2005 ▪ Abstract DNA mismatch repair (MMR) is an evolutionarily conserved process that corrects mismatches generated during DNA replication and escape proofreading. MMR proteins also participate in many other DNA transactions, such that inactivation of MMR can have wide-ranging biological consequences, which can be either beneficial or detrimental.

DNA repair and carcinogenesis [PDF]
BioDiscovery, 2014 The paper is dedicated to the natural phenomenon of cancer, with its possible causes, lifetime risks, mechanisms and possible outcomes discussed in fine detail. The molecular events resulting in uncontrolled cell growth and increased capacity to colonise distant topological sites are reviewed with regards to their impact as separate factors as well as ...

A novel splice variant of the DNA-PKcs gene is associated with clinical and cellular radiosensivity in a patient with xeroderma pigmentosum [PDF]
, 2010 Background: Radiotherapy-induced DNA double-strand breaks (DSBs) are critical cytotoxic lesions. Inherited defects in DNA DSB repair pathways lead to hypersensitivity to ionising radiation, immunodeficiency and increased cancer incidence.

Molecular Determinant of DIDS Analogs Targeting RAD51 Activity
Molecules, 2021 RAD51 is the central protein in DNA repair by homologous recombination (HR), involved in several steps of this process. It is shown that overexpression of the RAD51 protein is correlated with increased survival of cancer cells to cancer treatments.

Repair, abort, ignore? Strategies for dealing with UV damage [PDF]
, 2011 DNA repair is a prominent member of the nuclear transactions triad (replication, transcription, and repair). Sophisticated mechanisms govern the cellular process of decision-making (to repair or not to repair, to proceed with cell cycle or not and ...
