1 In order to assess whether the levels of some biomarkers (PAH-DNA adducts, nitro-PAH adducts to Hb and MN frequency) could be modulated by the genetic metabolic polymorphisms for CYP1A1 and GSTM1, we analysed in 76 coke-oven workers and 18 controls the CYP1A1 (MspI and Ile/Val sites) and the GSTM1 genotypes by a PCR assay. p-Aminohippuric Acid cytochrome P450 family 1 subfamily A member 1 Homo sapiens

3 Statistically significant (P = 0.03 and P = 0.01) higher percentages of the more susceptible GSTM1- subjects compared to the GSTM1+ subjects and of the more susceptible CYP1A1 Ile/Val individuals compared to the CYP1A1 Ile/Ile individuals were detected for high levels of PAH-DNA adducts in the high exposure group (namely high levels of 1-OHP). p-Aminohippuric Acid cytochrome P450 family 1 subfamily A member 1 Homo sapiens
4 In conclusion, a gene-environment interaction between PAH exposure and two metabolic genotypes involved in activation (CYP1A1) and detoxification (GSTM1) of PAHs, respectively, has been identified. p-Aminohippuric Acid cytochrome P450 family 1 subfamily A member 1 Homo sapiens
