Malonaldehyde deoxyguanosine adduct (M1dG) is a significant DNA lesion formed from the reaction between malonaldehyde (MDA), a product of lipid peroxidation, and deoxyguanosine, an essential component of DNA. The predominant MDA-derived DNA adduct is 3-(2-deoxy-B-d-erythro-pentafuranosyl)pyrimido[1,2-a]purin-10(3H)-one deoxyguanosine (M1dG). This adduct is mutagenic, causing structural changes in the DNA that can lead to mutations. M1dG has been detected and quantified in human tissues using sensitive techniques such as liquid chromatography-nanoelectrospray ionization-high-resolution tandem mass spectrometry (LC-NSI-HRMS/MS). The presence of M1dG is noteworthy because it serves as a biomarker for oxidative stress and has implications in cancer and other diseases. Studies have demonstrated that the formation of M1dG is comparable to DNA adducts from exogenous carcinogens, making it an important target for research in lifestyle and diet-related cancer risk assessments.
