DNA Repair [PDF]

open access: yesWormBook, 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

DNA MISMATCH REPAIR [PDF]

open access: yesAnnual 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.

Workshop on DNA repair [PDF]

open access: yesMutation Research/DNA Repair, 1992
A workshop on DNA repair with emphasis on eukaryotic systems was held, under the auspices of the EC Concerted Action on DNA Repair and Cancer, at Noordwijkerhout (The Netherlands) 14-19 April 1991. The local organization of the meeting was done under the auspices of the Medical Genetic Centre South-West, The Netherlands (MGC), c/o Department of ...

DNA demethylation by DNA repair [PDF]

open access: yesTrends in Genetics, 2009
Active DNA demethylation underlies key facets of reproduction in flowering plants and mammals and serves a general genome housekeeping function in plants. A family of 5-methylcytosine DNA glycosylases catalyzes plant demethylation via the well-known DNA base-excision-repair process.

DNA glycosylases: in DNA repair and beyond [PDF]

open access: yesChromosoma, 2011
The base excision repair machinery protects DNA in cells from the damaging effects of oxidation, alkylation, and deamination; it is specialized to fix single-base damage in the form of small chemical modifications. Base modifications can be mutagenic and/or cytotoxic, depending on how they interfere with the template function of the DNA during ...

The RecQ DNA Helicases in DNA Repair [PDF]

open access: yesAnnual Review of Genetics, 2010
The RecQ helicases are conserved from bacteria to humans and play a critical role in genome stability. In humans, loss of RecQ gene function is associated with cancer predisposition and/or premature aging. Recent experiments have shown that the RecQ helicases function during distinct steps during DNA repair; DNA end resection, displacement-loop (D-loop)

DNA Excision Repair [PDF]

open access: yesAnnual Review of Biochemistry, 1996
In nucleotide excision repair DNA damage is removed through incision of the damaged strand on both sides of the lesion, followed by repair synthesis, which fills the gap using the intact strand as a template, and finally ligation. In prokaryotes the damaged base is removed in a 12-13 nucleotide (nt)-long oligomer; in eukaryotes including humans the ...

Integrated multi-omics analyses on patient-derived CRC organoids highlight altered molecular pathways in colorectal cancer progression involving PTEN

open access: yesJournal of Experimental & Clinical Cancer Research, 2021
Background Colorectal cancer (CRC) represents the fourth leading cause of cancer-related deaths. The heterogeneity of CRC identity limits the usage of cell lines to study this type of tumor because of the limited representation of multiple features of ...

Molecular Determinant of DIDS Analogs Targeting RAD51 Activity

open access: yesMolecules, 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.

Compensatory metabolic networks in pancreatic cancers upon perturbation of glutamine metabolism

open access: yesNature Communications, 2017
Glutaminase inhibition (GLSi) has promising activity against certain cancers. Here, the authors show that GLSi has no effect on multiple mouse models of pancreatic cancer and characterize the metabolic pathways activated in response to GLSi whose ...
