目的:研究DNA修复基因RAD51和着色性干皮病基因( ERCC2/XPD)以及Bcl-2结合抗凋亡基因1(Bcl-2 associated athanogene 1,BAG-1)基因多态性与非小细胞肺癌(non-small cell lung cancer,NSCLC )遗传易感性的关系。方法:采用病例对照研究设计,选取100例非小细胞肺癌病例和80例正常对照。以ER-CC2/XPD Lys751Gln和RAD51 codon 135以及BAG-1codon 324基因多态性为研究位点,聚合酶链反应-限制性片段长度多态性( PCR-RFLP)方法对多态性进行检测。应用Logistic回归计算OR值及95%CI,比较不同基因型与NSCLC发病风险的关系。结果:ERCC2/XPD 751基因型在病例组的分布频率为 C/C型69例(69%)、C/A型26例(30%)和A/A型5例(5%)。与野生基因型C/C型相比,携带ERCC2/XPD C/A基因型和A/A基因型者患NSCLC的危险度比值比( odds ratio,OR)分别是1.53(95%CI:1.15-3.32)和0.58(95%CI:0.15-2.39)。BAG-1 codon 324基因型的分布频率为 C/C型81%(81/100)、C/T型19%(19/100)以及T/T型0%(0例)。与野生基因型C/C型相比,携带BAG-1 C/T基因型者患NSCLC的OR是1.28(95%CI:1.08-2.74)。RAD51 codon 135基因型的分布频率为 G/G 型67%(67/100)、G/C 型33%(33/100)、未现C/C型。与野生基因型G/G型相比,RAD51 G/C基因型者患NSCLC的OR是1.03(95%CI:1.06-2.29)。分析结果提示吸烟、环境危险因素与XPD Lys751Gln基因多态存在交互作用,交互效应OR值分别为2.24(95%CI:1.18-2.87)和2.53(95%CI:1.71-3.46),携带XPD Ly s751Gln突变基因者若同时暴露于吸烟、环境危险因素下,则患NSCLC的危险显著增加,相较未暴露于上述因素者,OR 值均增大。结论:BAG-1和ERCC2/XPD以及RAD51基因多态性可能与当地居民NSCLC遗传易感性有关,ERCC2/XPD与吸烟、饮酒、环境危险因素存在交互作用。

Objective:To study the relationship between Bcl-2 associated athanogene 1( BAG-1 ),xeroderma pigmentosum group D( ERCC2/XPD)and DNA repair gene RAD51 polymorphism and genetic susceptibility to non-small cell lung cancer( NSCLC ). Methods:A case - control study among 100 NSCLC cases and 80 controls matched by age and gender was conducted. The polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP)was used to analyze the genetic polymorphisms. Logistic regression model was employed to calculate the odd ratios( ORs)and 95% confidence intervals( CIs)of ERCC2/XPD Lys751Gln,BAG -1 codon 324 and RAD51 codon 135 with susceptibility of NSCLC. Results:The allele frequencies of C/C,C/A,and A/A of ERCC2/XPD 751Gln were 69%(69/100),26%(26/100)and 5%(5/100)in cases,respectively. The odds ratios for individ-uals carrying ERCC2/XPD C/A,and A/A were 1. 53(95% CI:1. 15-3. 32)and 0. 58(95% CI:0. 15-2. 39). The allele frequencies of C/C,C/T and T/T of BAG-1 codon 324 were 81%(81/100),19%(19/100)and 0%(0/100) in cases,respectively. The odds ratios for individuals carrying BAG-1 C/T was 1. 28(95% CI:1. 08-2. 74). The odds ratios for individuals carrying RAD51 G/C was 1. 03(95% CI:1. 06-2. 29). A significant interaction was found between ERCC2/XPD Lys751Gln polymorphism and smoking and air pollution in NSCLC. Conclusion:Genetic poly-morphism of ERCC2/XPD C/A,BAG-1 codon 324 C/T and RAD51 codon 135 G/C may be associated with the ge-netic susceptibility to NSCLC.
