Redmond Red as a Redox Probe for the DNA-Mediated Detection of Abasic Sites [PDF]

open access: yes, 2008
Redmond Red, a fluoropore containing a redox-active phenoxazine core, has been explored as a new electrochemical probe for the detection of abasic sites in double-stranded DNA.

Differential Binding of NLRP3 to non-oxidized and Ox-mtDNA mediates NLRP3 Inflammasome Activation

open access: yesCommunications Biology, 2023
The NLRP3 inflammasome is a key mediator of the innate immune response to sterile tissue injury and is involved in many chronic and acute diseases. Physically and chemically diverse agents activate the NLRP3 inflammasome.

Molecular Mechanisms Associated with Clustered Lesion-Induced Impairment of 8-oxoG Recognition by the Human Glycosylase OGG1

open access: yesMolecules, 2021
The 8-oxo-7,8-dihydroguanine, referred to as 8-oxoG, is a highly mutagenic DNA lesion that can provoke the appearance of mismatches if it escapes the DNA Damage Response.

A discontinuous DNA glycosylase domain in a family of enzymes that excise 5-methylcytosine [PDF]

open access: yes, 2010
DNA cytosine methylation (5-meC) is a widespread epigenetic mark associated to gene silencing. In plants, DEMETER-LIKE (DML) proteins typified by Arabidopsis REPRESSOR OF SILENCING 1 (ROS1) initiate active DNA demethylation by catalyzing 5-meC ...

DNA Charge Transport within the Cell [PDF]

open access: yes, 2015
The unique characteristics of DNA charge transport (CT) have prompted an examination of roles for this chemistry within a biological context. Not only can DNA CT facilitate long-range oxidative damage of DNA, but redox-active proteins can couple to the ...

The Base Excision Repair Pathway in the Nematode Caenorhabditis elegans

open access: yesFrontiers in Cell and Developmental Biology, 2020
Exogenous and endogenous damage to the DNA is inevitable. Several DNA repair pathways including base excision, nucleotide excision, mismatch, homologous and non-homologous recombinations are conserved across all organisms to faithfully maintain the ...

The trajectory of intrahelical lesion recognition and extrusion by the human 8-oxoguanine DNA glycosylase

open access: yesNature Communications, 2020
DNA glycosylases are lesion-specific enzymes that recognize specific nucleobase damages and catalyze their excision through cleavage of the glycosidic bond.

The DNA Repair Protein XRCC1 Functions in the Plant DNA Demethylation Pathway by Stimulating Cytosine Methylation (5-meC) Excision, Gap Tailoring, and DNA Ligation [PDF]

open access: yes, 2013
Background: Active DNA demethylation in plants is initiated by 5-meC DNA glycosylases of the ROS1/DME family and continued through a base excision repair pathway.

DNA glycosylases involved in base excision repair may be associated with cancer risk in BRCA1 and BRCA2 mutation carriers. [PDF]

open access: yesPLoS Genetics, 2014
Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of ...
