Abstract:
Purpose:The current study analyzed the polymorp hisms of DNA repair gene XRCC1 and relationship between genetic variations and s usceptibility to lung cancer Methods:A case-control study of 111 patients with lung cancer a nd 210 normal residents as controls was conducted to detect XRCC1 polymorphisms at Arg399Gln loci . Genotypes were analyzed by PCR-based restriction fragment le ngth polymorphism(RLFP) techniques. Results:XRCC1 codon 399 heterozygous genotype Arg/Gln might hav e weaker protection effect on squamous cell carcinoma and reduce the risk of lun g cancer on smokers. Homozygous genotype Gln/Gln of XRCC1 codon 399 might increa se the risk of lung cancer and have synergistic effect with smoking. Conclusions:The results demonstrated that genetic polymorphism of XRCC1 DNA repair gene might contribute to the susceptibility to lung cancer a nd have synergistic effect with smoking.
