Hydrogen peroxide induced genomic instability in nucleotide excision repair-deficient lymphoblastoid cells [PDF]

open access: yes, 2010
Copyright @ 2010 Gopalakrishnan et al; licensee BioMed Central Ltd.Background The Nucleotide Excision Repair (NER) pathway specialises in UV-induced DNA damage repair. Inherited defects in the NER can predispose individuals to Xeroderma Pigmentosum (XP).

DNA repair by photolyases

open access: yes, 2021
Photolyases belong to the cryptochrome/photolyase protein family (CPF) which perform different functions such as DNA repair, circadian photoreceptor, and transcriptional regulation.

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

open access: yesFEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Molecular Mechanisms of the Whole DNA Repair System: A Comparison of Bacterial and Eukaryotic Systems

open access: yesJournal of Nucleic Acids, 2010
DNA is subjected to many endogenous and exogenous damages. All organisms have developed a complex network of DNA repair mechanisms. A variety of different DNA repair pathways have been reported: direct reversal, base excision repair, nucleotide excision ...

Explosive mutation accumulation triggered by heterozygous human Pol ε proofreading-deficiency is driven by suppression of mismatch repair

open access: yeseLife, 2018
Tumors defective for DNA polymerase (Pol) ε proofreading have the highest tumor mutation burden identified. A major unanswered question is whether loss of Pol ε proofreading by itself is sufficient to drive this mutagenesis, or whether additional factors

CNOT6: A Novel Regulator of DNA Mismatch Repair

open access: yesCells, 2022
DNA mismatch repair (MMR) is a highly conserved pathway that corrects both base–base mispairs and insertion-deletion loops (IDLs) generated during DNA replication. Defects in MMR have been linked to carcinogenesis and drug resistance.

EGFR inhibits DNA mismatch repair [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Safeguarding the integrity of the genome should not be left to chance. Indeed, all organisms have highly effective mechanisms to detect and remove errors and lesions in DNA. DNA mismatch repair (MMR) serves as the final safeguard in assuring the fidelity of DNA replication from bacteria to humans and backstops the nucleotide selection and exonuclease ...

Endonuclease V-Mediated Deoxyinosine Excision Repair in Vitro

open access: yes, 2011
Deoxyinosine (dI) in DNA can arise from hydrolytic or nitrosative deamination of deoxyadenosine It is excised in a -repair pathway that is initiated by endonuclease V.

MutS alpha deficiency increases tolerance to DNA damage in yeast lacking postreplication repair

open access: yes, 2020
By combining mutations in DNA repair genes, important and unexpected interactions between different repair pathways can be discovered. In this study, we identified a novel link between mismatch repair (MMR) genes and postreplication repair (PRR) in ...

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have
