Base excision repair and cancer [PDF]

Cancer Letters, 2012
Base excision repair is the system used from bacteria to man to remove the tens of thousands of endogenous DNA damages produced daily in each human cell. Base excision repair is required for normal mammalian development and defects have been associated with neurological disorders and cancer.

PARP1 and PARP2 stabilise replication forks at base excision repair intermediates through Fbh1-dependent Rad51 regulation

Nature Communications, 2018
PARP1 has a well characterised role in DNA break repair and base excision repair, whereas the role of PARP2 is less well understood. Here, the authors show a requirement for PARP2 in stabilising replication forks that encounter base excision repair ...

Cooperation and interplay between base and nucleotide excision repair pathways: From DNA lesions to proteins [PDF]

Genetics and Molecular Biology, 2020
Base and nucleotide excision repair (BER and NER) pathways are normally associated with removal of specific types of DNA damage: small base modifications (such as those induced by DNA oxidation) and bulky DNA lesions (such as those induced by ultraviolet

The Role of DNA Damage and Repair in Idiopathic Pulmonary Fibrosis

Antioxidants, 2022
The mortality rate of idiopathic pulmonary fibrosis (IPF) increases yearly due to ineffective treatment. Given that the lung is exposed to the external environment, it is likely that oxidative stress, especially the stimulation of DNA, would be of ...

Removal of Misincorporated Ribonucleotides from Prokaryotic Genomes: An Unexpected Role for Nucleotide Excision Repair [PDF]

, 2013
Stringent steric exclusion mechanisms limit the misincorporation of ribonucleotides by high-fidelity DNA polymerases into genomic DNA. In contrast, low-fidelity Escherichia coli DNA polymerase V (pol V) has relatively poor sugar discrimination and ...

Base Excision Repair

Reactome - a curated knowledgebase of biological pathways, 2004
Publisher Summary The covalent structure of the nucleobases in DNA and RNA directly provides the information for all genetic transactions. Living systems expend considerable energy in an ongoing struggle against spontaneous genetic change. The most wide-ranging threat to genetic integrity is posed by the attack of environmental agents on DNA ...

Extended Frontobasal Approach for Skull Base Lesions

Indian Journal of Neurosurgery, 2021
Background Lesions involving the skull base can be approached by a variety of surgical corridors and extended frontobasal approach is one of them. It provides quite a wide exposure to lesions in the midline of anterior skull base, paranasal sinuses, and ...

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

, 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 ...

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

, 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 ...

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.
