8-Hydroxyguanine
Based on 1 Customer Validation
8-Hydroxyguanine is a DNA damage product under oxidative stress, which is formed when hydroxyl radicals attack guanine in DNA. 8-Hydroxyguanine induces mutagenesis and leads to a transversion from G to T. 8-Hydroxyguanine is a marker of DNA oxidative damage.

Human Endogenous Metabolite |
The most common product of ROS-induced base damage is 8-Hydroxyguanine. Failure to promptly remove 8-Hydroxyguanine often causes mutations during DNA replication. 8-Hydroxyguanine is cleared from cells by the 8-oxoG DNA glycosylase 1 (OGG1)-mediated oxidative damage base excision repair pathway so as to prevent cells from suffering dysfunction due to oxidative stress[2].
