Abstract excerpt
The cyclic 1,N(2)-propanodeoxyguanosine adducts, derived from alpha,beta-unsaturated aldehydes or enals, including acrolein (Acr), crotonaldehyde (Cro), and trans-4-hydroxy-2-nonenal (HNE), have been detected as endogenous DNA lesions in rodent and human tissues. Collective evidence has indicated that the oxidative metabolism of polyunsaturated fatty acids (PUFAs) is an important pathway for endogenous formation...
