The impact of glutathione s-transferase M1 and cytochrome P450 1A1 genotypes on white-blood-cell polycyclic aromatic hydrocarbon-DNA adduct levels in humans.

Carcinogenic polycyclic aromatic hydrocarbons (PAHs) form DNA adducts via a complex metabolic activation pathway that includes cytochrome P450 (CYP) 1A1, whereas intermediate metabolites can be detoxified by conjugation through pathways including glutathione s-transferase M1 (GSTM1). PAH-DNA adducts can be measured in peripheral white blood cells (WBCs) and… CONTINUE READING
