DNA Base Excision Repair Intermediates Influence Duplex–Quadruplex Equilibrium
Molecules, 2023 Although genomic DNA is predominantly duplex under physiological conditions, particular sequence motifs can favor the formation of alternative secondary structures, including the G-quadruplex.

Viruses with U-DNA: New Avenues for Biotechnology
Viruses, 2021 Deoxyuridine in DNA has recently been in the focus of research due to its intriguing roles in several physiological and pathophysiological situations. Although not an orthodox DNA base, uracil may appear in DNA via either cytosine deamination or thymine ...

Regulation of nucleotide excision repair by UV-DDB: prioritization of damage recognition to internucleosomal DNA [PDF]
, 2011 How tightly packed chromatin is thoroughly inspected for DNA damage is one of the fundamental unanswered questions in biology. In particular, the effective excision of carcinogenic lesions caused by the ultraviolet (UV) radiation of sunlight depends on ...

Variation in base excision repair capacity [PDF]
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2011 The major DNA repair pathway for coping with spontaneous forms of DNA damage, such as natural hydrolytic products or oxidative lesions, is base excision repair (BER). In particular, BER processes mutagenic and cytotoxic DNA lesions such as non-bulky base modifications, abasic sites, and a range of chemically distinct single-strand breaks.

A function of thymine DNA glycosylase-initiated DNA repair in maintaining epigenome stability [PDF]
, 2013 The Thymine DNA Glycosylase (TDG) was initially discovered by its ability to excise the deamination products of cytosine and 5-methylcytosine (5-mC), and therefore thought to initiate base excision repair (BER) of the resulting G•U and G•T mismatches.

Mitochondrial base excision repair assays [PDF]
Methods, 2010 The main source of mitochondrial DNA (mtDNA) damage is reactive oxygen species (ROS) generated during normal cellular metabolism. The main mtDNA lesions generated by ROS are base modifications, such as the ubiquitous 8-oxoguanine (8-oxoG) lesion; however, base loss and strand breaks may also occur.

Inter-individual variation in nucleotide excision repair in young adults: effects of age, adiposity, micronutrient supplementation and genotype [PDF]
, 2009 Nucleotide excision repair (NER) is responsible for repairing bulky helix-distorting DNA lesions and is essential for the maintenance of genomic integrity.

Overview of Base Excision Repair Biochemistry [PDF]
Current Molecular Pharmacology, 2012 Base excision repair (BER) is an evolutionarily conserved pathway, which could be considered the "workhorse" repair mechanism of the cell. In particular, BER corrects most forms of spontaneous hydrolytic decay products in DNA, as well as everyday oxidative and alkylative modifications to bases or the sugar phosphate backbone.

Base Sequence Context Effects on Nucleotide Excision Repair
Journal of Nucleic Acids, 2010 Nucleotide excision repair (NER) plays a critical role in maintaining the integrity of the genome when damaged by bulky DNA lesions, since inefficient repair can cause mutations and human diseases notably cancer. The structural properties of DNA lesions
