Research Abstract

We developed a novel method to detectgenomic sites harboring DNA damage comprehensively and verified practical effectiveness of the method. We conducted immunoprecipitations with genomic DNA extracted from target cells of ferric nitrilotriacetate-induced rodent renal carcinogenesis model using antibodies against two types of representative oxidative modified bases, 8-OHdG and acrolein-dA, and analyzed genomic distributions of the oxidative DNA damages by the use of array-CGH.
