Effect of the XRCC1 codon 399 polymorphism on the repair of vinyl chloride metabolite-induced DNA damage

Abstract

The average epsilonA adduct levels were statistically significantly higher in the variant cells compared to the wild-type cells at 8 and 24 h following exposure (P Conclusion: These results are consistent with the epidemiologic findings of the types of VC-induced biomarkers observed in exposed individuals and the mutational spectra found in the resultant tumors as well as the key role that BER, especially XRCC1, plays in this carcinogenic pathway.
