Oxidative stress and 8-oxoguanine repair are enhanced in colon adenoma and carcinoma patients. [PDF]

open access: yes, 2010
Oxidative stress is involved in the pathogenesis of colon cancer. We wanted to elucidate at which stage of the disease this phenomenon occurs. In the examined groups of patients with colorectal cancer (CRC, n = 89), benign adenoma (AD, n = 77) and ...

Chemistry and Biology of 8,5\u27-Cyclo-2\u27-deoxyguanosine and Other DNA Lesions

open access: yes, 2013
8,5’-Cyclopurine deoxynucleosides are unique tandem lesions containing an additional covalent bond between the base and the sugar. These mutagenic and genotoxic lesions are repaired only by nucleotide excision repair (NER). It was shown that the R-cdA is

Stability of N‑Glycosidic Bond of (5′S)‑8,5′-Cyclo-2′-deoxyguanosine

open access: yes, 2016
8,5′-Cyclopurine deoxynucleosides are unique tandem lesions containing an additional covalent bond between the base and the sugar. These mutagenic and genotoxic lesions are repaired only by nucleotide excision repair. The N-glycosidic (or C1′-N9) bond of

Induction of 8,5′-Cyclo-2′-deoxyadenosine and 8,5′-Cyclo-2′-deoxyguanosine in Isolated DNA by Fenton-Type Reagents

open access: yes, 2016
Exposure of aqueous solutions of DNA to X- or γ-rays, which induces the hydroxyl radical as one of the major reactive oxygen species (ROS), can result in the generation of a battery of single-nucleobase and bulky DNA lesions. These include the (5′R) and (

8-Fluoro-N-2-isobutyryl-2′-deoxyguanosine: Synthesis and Reactivity

open access: yes, 2020
3′,5′-O-Bis(tert-butyldimethylsilyl)-8-fluoro-N-2-isobutyryl-2′-deoxyguanosine was synthesized from 3′,5′-O-bis(tert-butyldimethylsilyl)-N-2-isobutyryl-2′-deoxyguanosine by the treatment with N-fluorobenzenesulfonimide.

Imidazopurinones are markers of physiological genomic damage linked to DNA instability and glyoxalase 1-associated tumour multidrug resistance [PDF]

open access: yes, 2010
Glyoxal and methylglyoxal are reactive dicarbonyl metabolites formed and metabolized in physiological systems. Increased exposure to these dicarbonyls is linked to mutagenesis and cytotoxicity and enhanced dicarbonyl metabolism by overexpression of ...

One-Electron Oxidation of the Guanine Moiety of 2‘-Deoxyguanosine:  Influence of 8-Oxo-7,8-dihydro-2‘-deoxyguanosine

open access: yes, 2016
The influence of 8-oxo-7,8-dihydro-2‘-deoxyguanosine (8-oxodGuo) on riboflavin and UVA-mediated one-electron oxidation of an aqueous aerated solution of 2‘-deoxyguanosine (dGuo) has been studied.

Structures of (5′S)-8,5′-Cyclo-2′-deoxyguanosine Mismatched with dA or dT

open access: yes, 2015
Diastereomeric 8,5′-cyclopurine 2′-deoxynucleosides, containing a covalent bond between the deoxyribose and the purine base, are induced in DNA by ionizing radiation.
