DNA Repair

Metrics details. DNA is subject to constant chemical modification and damage, which eventually results in variable mutation rates throughout the genome. Although detailed molecular mechanisms of DNA damage and repair are well understood, damage impact and execution of repair across a genome remain poorly defined. To bridge the gap between our understanding of DNA repair and mutation distributions, we developed a novel method, AP-seq, capable of mapping apurinic sites and 8-oxo-7,8-dihydroguanine bases at approximately bp resolution on a genome-wide scale. We directly demonstrate that the accumulation rate of apurinic sites varies widely across the genome, with hot spots acquiring many times more damage than cold spots. Apurinic sites and oxidative damage are also highly enriched in transposable elements and other repetitive sequences.

As one of the most extensively studied DNA repair processes in both prokaryotes and eukaryotes, nucleotide excision appears to be not only universally present.

DNA damage and repair in plants – from models to crops

The genomic integrity of every organism is constantly challenged by endogenous and exogenous DNA-damaging factors. Mutagenic agents cause reduced stability of plant genome and have a deleterious effect on development, and in the case of crop species lead to yield reduction. It is crucial for all organisms, including plants, to develop efficient mechanisms for maintenance of the genome integrity.

The BER pathway is widely used to repair DNA damage in cells, but it can also introduce unwanted mutations and is sometimes hijacked by other pathways. DNA can be damaged in many ways—bases can, for example, be oxidized, alkylated or deaminated—so cells need a way to repair DNA damage. This process involves three basic steps: first, enzymes called nucleases break the DNA strand that is damaged on either side of the lesion so that the section containing the lesion can be removed; second, DNA polymerases make a new stretch of DNA to replace the section that has been removed, using the undamaged strand as a template; third, DNA ligases join this new stretch to the existing DNA.

DNA repair diseases: what do they tell us about cancer and aging? Send correspondence to. The discovery of DNA repair defects in human syndromes, initially in xeroderma pigmentosum XP but later in many others, led to striking observations on the association of molecular defects and patients' clinical phenotypes. For example, patients with syndromes resulting from defective nucleotide excision repair NER or translesion synthesis TLS present high levels of skin cancer in areas exposed to sunlight. However, some defects in NER also lead to more severe symptoms, such as developmental and neurological impairment and signs of premature aging.

DNA Damage, Mutagenesis, and DNA Repair

The consequences of DNA damage have been the subject of numerous studies in the last few decades. Replication of damaged DNA may result in an increased rate of mutations in the progeny, which may impart deleterious consequence on the organism. Various types of cancers have been linked to DNA damages and it is believed that the initiation of carcinogenesis may result from misreplication of the damaged DNA. DNA repair systems maintain the integrity of the genome by removing the damaged base, sugar, or phosphate from the DNA.
