Types of damaged lesions frequently found inside clustered DNA damage sites include oxidized bases, abasic sites, nucleotide dimers, strand breaks or their complex combinations.
With radionuclide-induced exposure, the repair is induced during the dose delivery and therefore the half-time value with which sub-lethally damaged lesions are repaired is very critical.
DNA damage checkpoint acts as a process of signal transduction to transmit information from damaged lesions to cell cycle regulators.
Scaffolds alone will not be sufficient to enable the maximal repair of the damaged lesions.
In summary, when oxidatively damaged lesions to G are formed in 4-track G4s, such as VEGF-4, the resulting structures prevent the BER process; conversely, rolling the "spare tire" domain into the damaged G4 (i.e., VEGF-5) provides a new structure allowing initiation of BER.
Taking care not to damage lesion area, the teeth were reduced in size (both breadthwise and lengthwise) to better fit the SEM stub.
Therefore cancer cells also utilize the DNA repair machinery to process DNA damaging lesions and maintain cellular survival.
In individual patients, voxels identified as damaged (see 'Lesion detection') were set to zero in the contrast images before being entered into the group analysis.
7,8-Dihydro-8-oxoguanine (oxoG), the predominant oxidative DNA damage lesion, is processed differently by high-fidelity and Y-family lesion bypass polymerases.
Around active NMO lesions AQP4 may selectively be lost in the absence of aquaporin 1 (AQP1) loss or other structural damage (lesion type 4).
