Base excision repair and the role of
The correction of exogenous and endogenous environmental insult to DNA involves a series of DNA repair mechanisms that reduce the likelihood of mutation accumulation and hence an increased probability of tumour development.

Bacillus Calmette-Guerin Increases Base Excision Repair in Bladder Cancer Cells
Objective:Most patients with non-muscle-invasive bladder cancer (NMIBC) do not respond to intravesical Bacillus Calmette-Guerin (BCG) immunotherapy and have high risk of NMIBC recurrence and progression.

Base excision and nucleotide excision repair pathways in mycobacteria
About a third of the human population is estimated to be infected with Mycobacterium tuberculosis. The bacterium displays an excellent adaptability to survive within the host macrophages. As the reactive environment of macrophages is capable of inducing DNA damage, the ability of the pathogen to safeguard its DNA against the damage is of paramount ...

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

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

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 ...

Extended Frontobasal Approach for Skull Base Lesions
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 ...

REPAIRtoire--a database of DNA repair pathways. [PDF]
REPAIRtoire is the first comprehensive database resource for systems biology of DNA damage and repair. The database collects and organizes the following types of information: (i) DNA damage linked to environmental mutagenic and cytotoxic agents, (ii ...

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 ...
