摘要
目的 探讨TEA转录因子1(TEAD1)基因单核苷酸多态性(SNP)rs2304733、TEA转录因子4(TEAD4)SNP rs7135838和rs1990330与非贲门胃癌变发病风险的关系.方法 采用酶联免疫吸附测定法(ELISA)检测正常对照组血清样本中抗幽门螺杆菌(Hp)的特异性抗体,根据抗体滴度将470例正常对照组分为Hp感染阴性组(n=223)和阳性组(n=247).在450例非贲门胃癌病例组和470例对照组中,采用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)技术对各SNP位点进行基因分型,采用非条件性Logistic回归评估各SNP位点与非贲门胃癌变发病风险的关系.结果 TEAD1、TEAD4各SNP位点均与Hp感染没有关联;TEAD1 rs2304733与非贲门胃癌的发病风险相关,与携带TT基因型者相比,携带CT基因型及CC基因型者均增加了非贲门胃癌的发病风险(CT vs TT:OR=2.321,95％CI:1.690～3.188;CC vs TT:OR=5.140,95％CI:1.080～24.463);TEAD4 rs1990330与非贲门胃癌发病风险相关,与携带GG基因型者相比,携带GT基因型者增加了非贲门胃癌的发病风险(OR=2.405,95％CI:1.480～3.908);TEAD4 rs7135838与非贲门胃癌的发病风险无关联;TEAD1 rs2304733、TEAD4 rs7135838以及rs1990330对非贲门胃癌发病风险存在交互作用(P<0.05).结论 在包头地区汉族人群中,TEAD1 rs2304733、TEAD4 rs1990330在Hp感染中不起主要作用,在非贲门胃癌发病风险中可能起一定作用;TEAD4 rs7135838在Hp感染以及非贲门胃癌发病风险中可能均不起主要作用;TEAD1 rs2304733、TEAD4 rs1990330对非贲门胃癌发病风险的协同效应最强,为最佳交互模型.
Abstract
Objective To investigate the associations of the single nucleotide polymorphism (SNP) rs2304733 in TEA domain transcription factor 1 (TEAD1) , rs7135838 and rs1990330 in TEA domain transcription factor 4 (TEAD4) genes with the risk of non-cardia gastric carcinogenesis.Methods Enzyme linked immunosorbent assay (ELISA) was used to detect specific antibodies against Helicobacter pylori(Hp) in serum samples of the normal con-trol group.470 normal controls were divided into Hp infection negative group (n=223) and positive group (n=247) based on antibody titers.In the 450 non-cardia gastric cancer cases and 470 controls, polymerase chain reac-tion-restriction fragment length polymorphism (PCR-RFLP) was used to genotype the each SNP locus.The uncon-ditional Logistic regression method was used to evaluate the associations between each SNP locus and the risk of non-cardia gastric carcinogenesis.Results The SNPs of TEAD1 and TEAD4 were not associated with Hp infec-tion.TEAD1 rs2304733 was associated with the risk of non-cardia gastric cancer.Compared with the carriers of TT genotype, the carries of CT and CC genotypes had an increased risk of non-cardia gastric cancer (CT vs TT:OR=2.321 , 95％CI:1.690-3.188;CC vs TT:OR=5.140 , 95％CI:1.080-24.463) .TEAD4 rs1990330 was as-sociated with the risk of non-cardia gastric cancer.Compared with the carriers of GG genotype, those with GT geno-type had an increased risk of non-cardia gastric cancer (OR = 2.405 , 95％ CI: 1.480 - 3.908) .TEAD4 rs7135838 was not associated with the risk of non-cardia gastric cancer.TEAD1 rs2304733, TEAD4 rs7135838 and rs1990330 had interaction effects on the risk of non-cardia gastric cancer (P<0.05).Conclusion In Baotou Han population, TEAD1 rs2304733 and TEAD4 rs1990330 do not play a major role in Hp infection, but may play a role in the risk of non-cardia gastric cancer.TEAD4 rs7135838 may not play a major role in the risk of Hp infec-tion and non-cardia gastric cancer.TEAD1 rs2304733 and TEAD4 rs1990330 have the strongest synergistic effect on the risk of non-cardia gastric cancer, which is the best interaction model.
