OGG1 and testicular embryonal carcinoma: The same metal-based NPs and TiO2-NPs showed a dose and time dependent cytotoxic effect also in the Ntera2 (NT2, human testicular embryonic carcinoma) cell line and in primary testicular cells obtained from wild type (WT) C57BL6 mice and 8-oxoguanine DNA glycosylase knock-out (Ogg1−/−) (KO) genotype treated with concentrations of NPs ranging from 0 to 100 μg/mL [51].
