Resistance to Nucleotide Excision Repair of Bulky Guanine Adducts Opposite Abasic Sites in DNA Duplexes and Relationships between Structure and Function. [PDF]
The nucleotide excision repair of certain bulky DNA lesions is abrogated in some specific non-canonical DNA base sequence contexts, while the removal of the same lesions by the nucleotide excision repair mechanism is efficient in duplexes in which all ...

Base excision repair (BER) corrects DNA damage from oxidation, deamination and alkylation. Such base lesions cause little distortion to the DNA helix structure. BER is initiated by a DNA glycosylase that recognizes and removes the damaged base, leaving an abasic site that is further processed by short-patch repair or long-patch repair that largely uses

DNA Repair Repertoire of the Enigmatic Hydra
Since its discovery by Abraham Trembley in 1744, hydra has been a popular research organism. Features like spectacular regeneration capacity, peculiar tissue dynamics, continuous pattern formation, unique evolutionary position, and an apparent lack of ...

Base Excision Repair in the Mitochondria [PDF]
ABSTRACTThe 16.5 kb human mitochondrial genome encodes for 13 polypeptides, 22 tRNAs and 2 rRNAs involved in oxidative phosphorylation. Mitochondrial DNA (mtDNA), unlike its nuclear counterpart, is not packaged into nucleosomes and is more prone to the adverse effects of reactive oxygen species (ROS) generated during oxidative phosphorylation. The past

OGG1 in Lung—More than Base Excision Repair
As the organ executing gas exchange and directly facing the external environment, the lungs are challenged continuously by various stimuli, causing the disequilibration of redox homeostasis and leading to pulmonary diseases.

Nucleotide excision repair proteins are involved in the repair of UV-induced DNA damage. Here, the authors show that NER proteins, DDB2, XPC, and XPA play a vital role in the 8-oxoguanine repair by coordinating with base excision repair protein OGG1.

Base Flipping in Nucleotide Excision Repair [PDF]
UvrB, the ultimate damage-binding protein in bacterial nucleotide excision repair is capable of binding a vast array of structurally unrelated lesions. A beta-hairpin structure in the protein plays an important role in damage-specific binding. In this paper we have monitored DNA conformational alterations in the UvrB-DNA complex, using the fluorescent ...

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

Biochemical characterization and DNA repair pathway interactions of Mag1-mediated base excision repair in Schizosaccharomyces pombe [PDF]
The Schizosaccharomyces pombe mag1 gene encodes a DNA repair enzyme with sequence similarity to the AlkA family of DNA glycosylases, which are essential for the removal of cytotoxic alkylation products, the premutagenic deamination product hypoxanthine ...
