In the present study, we investigated the polymorphisms of the following selected members of the base and nucleotide excision repair genes: XPC (Lys939Gln), XPD (Lys751Gln), XRCC1(Arg399Gln), and hOGG1(Ser326Ser), and the risk they present toward the development of lung cancer, with emphasis on the effect of chromium exposure.
In the present study, we investigated the polymorphisms of following selected DNA repair genes: XPC (Lys939Gln), XPD (Lys751Gln), hOGG1 (Ser326Cys) and XRCC1 (Arg399Gln), and the risks they present towards the development of lung cancer with the emphasis to gender differences within the Slovak population.
Using genomic DNA extracted from blood samples, we identified wild-type and polymorphic variants of XPD (Arg156Arg and Lys751Gln), XRCC1 (Arg194Trp and Arg399Gln) and XRCC3 (Thr241Met), and the poly (AT) insertion/deletion of XPC (PAT).
