Increased formation of hepatic N2-ethylidene-2'-deoxyguanosine DNA adducts in aldehyde dehydrogenase 2-knockout mice treated with ethanol

Abstract excerpt

N2-ethylidene-2'-deoxyguanosine (N2-ethylidene-dG) is a major DNA adduct induced by acetaldehyde. Although it is unstable in the nucleoside form, it is relatively stable when present in DNA. In this study, we analyzed three acetaldehyde-derived DNA adducts, N2-ethylidene-dG, N2-ethyl-2'-deoxyguanosine (N2-Et-dG) and alpha-methyl-gamma-hydroxy-1,N2-propano-2'-deoxyguanosine (alpha-Me-gamma-OH-PdG) in the liver DNA...
