摘要： Variation of individuals’ DNA repair capacity has been linked to cancer susceptibility. The xeroderma pigmentsum group F (XPF) plays a pivotal role in nucleotide-excision repair (NER) pathway. This study was to examine the functional significance of promoter polymorphisms and their association with lung cancer risk. The function of promoter polymorphisms was tested by a set of biochemical assays, and their effects on lung cancer risk were determined by a case-control analysis of 988 patients with lung cancer and 986 controls. The −673T allele showed a significantly higher transcriptional activity as compared with the −673C allele. The −673TT genotype was associated with a decreased risk of lung cancer compared with the CC genotype (adjusted OR=0.62, 95% CI=0.42–0.91; =0.015) and this effect was more significant among males (adjusted OR=0.55, 95% CI=0.35–0.86; =0.009), elder subjects (adjusted OR=0.51, 95% CI=0.30–0.86; =0.012), and light smokers (adjusted OR=0.35, 95% CI=0.14–0.88; =0.026). These findings suggest that functional polymorphisms influencing DNA repair capacity may confer susceptibility to lung cancer.
