Syntheses and characterizations of the in vivo replicative bypass and mutagenic properties of the minor-groove O2-alkylthymidine lesions. [PDF]

open access: yes, 2014
Endogenous metabolism, environmental exposure, and treatment with some chemotherapeutic agents can all give rise to DNA alkylation, which can occur on the phosphate backbone as well as the ring nitrogen or exocyclic nitrogen and oxygen atoms of ...

Reduction in squamous cell carcinomas in mouse skin by dietary zinc supplementation. [PDF]

open access: yes, 2016
Inadequate dietary Zn consumption increases susceptibility to esophageal and other cancers in humans and model organisms. Since Zn supplementation can prevent cancers in rodent squamous cell carcinoma (SCC) models, we were interested in determining if it

Design, Synthesis, and Analysis of Minor Groove Binder Pyrrolepolyamide-2′-Deoxyguanosine Hybrids

open access: yesJournal of Nucleic Acids, 2010
Pyrrolepolyamide-2′-deoxyguanosine hybrids (Hybrid 2 and Hybrid 3) incorporating the 3-aminopropionyl or 3-aminopropyl linker were designed and synthesized on the basis of previously reported results of a pyrrolepolyamide-adenosine hybrid (Hybrid 1 ...

Evaluation of oxidative stress effects on different macromolecules in adult growth hormone deficiency.

open access: yesPLoS ONE, 2020
Adult growth hormone deficiency (GHD) is being increasingly recognized to cause premature mortality exacerbated by oxidative stress. A case-control observational study has been performed with the primary objective of evaluating new parameters of ...

In vitro transcription of vesicular stomatitis virus. Incorporation of deoxyguanosine and deoxycytidine, and formation of deoxyguanosine caps.

open access: yesJournal of Biological Chemistry, 1982
Detergent-disrupted vesicular stomatitis virus carried out in vitro transcription at a reduced rate in the presence of deoxyguanosine triphosphate. The transcripts annealed completely to excess vesicular stomatitis virus genomic RNA and consistent of the short leader RNA and even polyadenylated messenger RNA.

Ab-initio study of model guanine assemblies: The role of pi-pi coupling and band transport

open access: yes, 2001
Several assemblies of guanine molecules are investigated by means of first-principle calculations. Such structures include stacked and hydrogen-bonded dimers, as well as vertical columns and planar ribbons, respectively, obtained by periodically ...

Interaction of Nucleosides and Related Compounds with Nucleic Acids as Indicated by the Change of Helix-Coil Transition Temperature [PDF]

open access: yes, 1962
A series of compounds has been tested for effectiveness in lowering the melting temperature of poly A and of thymus DNA. The order of increasing activity was found to be: adonitol, methyl riboside (both negligible) < cyclohexanol < phenol, pyrimidine ...

Oligonucleotide Incorporation of 8-Thio-2‘-deoxyguanosine [PDF]

open access: yesOrganic Letters, 2004
[reaction: see text] 8-Thio-2'-deoxyguanosine (SdG) is a useful analogue of the abundant promutagen 8-oxo-2'-deoxyguanosine (OdG). Its synthesis and DNA incorporation using standard phosphoramidite chemistry is reported. To prevent oxidation during DNA synthesis, the sulfur was protected as a 2-(trimethylsilyl)ethyl sulfide.
