The levels of oxidative stress markers [8-oxodG, 15-F2t-IsoP, protein carbonyls] and cytogenetic parameters [FG/100, %AB.C., and (ace)] in subjects living in Prague (N=64) and in the heavily polluted Ostrava region (N=75) were investigated. Despite the fact, that the levels of air pollutants were significantly higher in Ostrava vs. Prague, neither differences in biomarkers of oxidative stress or in cytogenetic parameters between these two locations were found. Subjects living in Ostrava has increased odds of having above-median levels of XRCC5 expression. Above-median levels of 8-oxodG were associated with decreased levels of vitamin C and E, which were elevated in subjects from Ostrava. It may be concluded, that air pollution by c-PAHs affects XRCC5 gene expression, which probably protects subjects from Ostrava against the induction of a higher frequency of translocations, and elevated vitamin C and E levels decrease the levels of 8-oxodG.
