1301por Sanz-Serrano, Julen, Vettorazzi, Ariane, Muruzabal, Damian, Azqueta, Amaya, López de Cerain, Adela“…In addition, the in vitro standard and enzyme-modified (human 8-oxoguanine DNA glycosylase 1 (hOGG), endonuclease III (EndoIII), human alkyladenine DNA glycosylase (hAAG)) comet assay (S9−/S9+) was conducted in order to assess the potential premutagenic lesions in TK6 cells. …”

The HepG2 cells experienced genotoxicity for all GNP ligands; however, they were able to initiate repair mechanisms and recover DNA damage, except for two functionalization chemistries.…”

Using the comet assay, 1 Gy radiation exposure decreased the percentage of leukocytes with less than 5% DNA in the tail (<5% DNAT), and we propose that radioresistance induction might increase the number of cells with <5% DNAT after radiation exposure. …”
