Endonuclease activities of MutLα and its homologs in DNA mismatch repair. [PDF]

open access: yes, 2016
MutLα is a key component of the DNA mismatch repair system in eukaryotes. The DNA mismatch repair system has several genetic stabilization functions. Of these functions, DNA mismatch repair is the major one.

Sensing and Processing of DNA Interstrand Crosslinks by the Mismatch Repair Pathway

open access: yesCell Reports, 2017
Summary: DNA interstrand crosslinks (ICLs) that are repaired in non-dividing cells must be recognized independently of replication-associated DNA unwinding. Using cell-free extracts from Xenopus eggs that support neither replication nor transcription, we

A Strategy for Imidazotetrazine Prodrugs with Anti-cancer Activity Independent of MGMT and MMR [PDF]

open access: yes, 2012
The imidazotetrazine ring is an acid-stable precursor and prodrug of highly-reactive alkyl diazonium ions. We have shown that this reactivity can be managed productively in an aqueous system for the generation of aziridinium ions with 96% efficiency. The

Signalling cell cycle arrest and cell death through the MMR System [PDF]

open access: yes, 2006
Loss of DNA mismatch repair (MMR) in mammalian cells, as well as having a causative role in cancer, has been linked to resistance to certain DNA damaging agents including clinically important cytotoxic chemotherapeutics.

Decreased transcription-coupled nucleotide excision repair capacity is associated with increased p53- and MLH1-independent apoptosis in response to cisplatin

open access: yesBMC Cancer, 2010
Background One of the most commonly used classes of anti-cancer drugs presently in clinical practice is the platinum-based drugs, including cisplatin.

DNA charge transport as a first step in coordinating the detection of lesions by repair proteins [PDF]

open access: yes, 2012
Damaged bases in DNA are known to lead to errors in replication and transcription, compromising the integrity of the genome. We have proposed a model where repair proteins containing redox-active [4Fe-4S] clusters utilize DNA charge transport (CT) as a ...

Escherichia coli frameshift mutation rate depends on the chromosomal context but not on the GATC content near the mutation site. [PDF]

open access: yesPLoS ONE, 2012
Different studies have suggested that mutation rate varies at different positions in the genome. In this work we analyzed if the chromosomal context and/or the presence of GATC sites can affect the frameshift mutation rate in the Escherichia coli genome.

Rad27 and Exo1 function in different excision pathways for mismatch repair in Saccharomyces cerevisiae

open access: yesNature Communications, 2021
Defects in DNA mismatch repair (MMR) have been linked to inherited and sporadic cancers. Here the authors demonstrate that the DNA repair protein Rad27 (human FEN1) functions in one of three redundant mispair excision pathways, where its flap ...

Non-homologous end-joining pathway associated with occurrence of myocardial infarction: gene set analysis of genome-wide association study data [PDF]

open access: yes, 2013
<p>Purpose: DNA repair deficiencies have been postulated to play a role in the development and progression of cardiovascular disease (CVD). The hypothesis is that DNA damage accumulating with age may induce cell death, which promotes formation of ...

The Eukaryotic Mismatch Recognition Complexes Track with the Replisome during DNA Synthesis.

open access: yesPLoS Genetics, 2015
During replication, mismatch repair proteins recognize and repair mispaired bases that escape the proofreading activity of DNA polymerase. In this work, we tested the model that the eukaryotic mismatch recognition complex tracks with the advancing ...
