Abstract

The 8-hydroxy-2 '-deoxyguanosine (8-OHdG) damages are base damages induced by reactive oxygen species. We aimed to investigate the role of Androgen Receptor and NKX3.1 in 8-OHdG formation and repair activation by quantitating the DNA damage using Aklides.NUK system. The data demonstrated that the loss of NKX3.1 resulted in increased oxidative DNA damage and its overexpression contributes to the removal of menadione-induced 8-OHdG damage even under oxidative stress conditions. Moreover, 8-oxoguanine DNA glycosylase-1 (OGG1) expression level positively correlates to NKX3.1 expression. Also in this study, first time a reliable cell-based quantitation method for 8-OHdG damages is reported and used for data collection.
