In situ evaluation of anticancer drug methotrexate-DNA interaction using a DNA-electrochemical biosensor and AFM characterization
(Royal Soc Chemistry, 2011-01-01)
An in situ evaluation of the dsDNA-methotrexate (MTX) interaction was performed by voltammetry using a DNA-electrochemical biosensor and characterized by atomic force microscopy (AFM) at a highly oriented pyrolytic graphite ...

Nuclear DNA content in 20 species of Siluriformes (Teleostei: Ostariophysi) from the Neotropical region
(Sociedade Brasileira de Genética, 2004-01-01)
In the present study, 20 species of Siluriformes fish were analyzed in order to determine their nuclear DNA content and compare these data with their diploid number. In addition, the extension and importance of the changes ...

Exogenous DNA uptake by bovine spermatozoa does not induce DNA fragmentation
(ELSEVIER SCIENCE INC, 2010)
Sperm-mediated gene transfer (SMGT) is a fast and low-cost method used to produce transgenic animals. The objective of this study was to evaluate the effects of the concentration of exogenous DNA and the duration of ...
DNA damage tolerance pathway involving DNA polymerase ι and the tumor suppressor p53 regulates DNA replication fork progression
(National Academy Of Sciences, 2016-07)
DNA damage tolerance facilitates the progression of replication forks that have encountered obstacles on the template strands. It involves either translesion DNA synthesis initiated by proliferating cell nuclear antigen ...
DNA extraction from fixed cytogenetic cell suspensions

Distribution of 45S and 5S rDNA sites in 23 species of Eleocharis (Cyperaceae)
(Springer, 2010-10-01)
Studies of rDNA location in holocentric chromosomes of the Cyperaceae are scarce, but a few reports have indicated the occurrence of multiple 45S rDNA sites at terminal positions, and in the decondensed state of these ...

Novel properties of melanins include promotion of DNA strand breaks, impairment of repair, and reduced ability to damage DNA after quenching of singlet oxygen
(ELSEVIER SCIENCE INCNEW YORK, 2012)
Melanins have been associated with the development of melanoma and its resistance to photodynamic therapy (PDT). Singlet molecular oxygen (102), which is produced by ultraviolet A solar radiation and the PDT system, is ...
