Human Endogenous Metabolite
8-Hydroxy-2'-deoxyguanosine (8-OHdG) is a good biomarker for risk assessment of various cancers and degenerative diseases. The biomarker 8-Hydroxy-2'-deoxyguanosine (8-OHdG) or 8-oxodG has been a pivotal marker for measuring the effect of endogenous oxidative damage to DNA and as a factor of initiation and promotion of carcinogenesis. The biomarker has been used to estimate the DNA damage in humans after exposure to cancer-causing agents, such as tobacco smoke, asbestos fibers, heavy metals, and polycyclic aromatic hydrocarbons.
