摘 要: 【目的】 探讨烟酰胺腺嘌呤二核苷酸磷酸(NADPH)氧化酶p22phox亚基基因His72Tyr与脂联素基因启动子-11391G/A多态性的交互作用以及与大肠癌及其分化程度的关系。 【方法】 选择我院2009年7月至2014年12月收治的大肠癌患者668例,分为高分化组、中分化组、低分化组、未分化组各162例,以162例健康体检者作为对照组,各组在年龄、性别、民族、籍贯和生活习惯方面无显著性差异,以上述各组患者的外周血白细胞为样本,利用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术分析了NADPH氧化酶p22phox亚基基因His72Tyr和脂联素基因启动子-11391G/A多态性。【结果】 His72Tyr (TT)基因型和-11391G/A (AA)基因型频率分布分别为50.62%和50.00% (高分化组)、64.20% 和64.81% (中分化组)、69.75% 和69.75%(低分化组)、76.54% 和77.16% (未分化组)及 22.84% 和22.84% (健康对照组),上述基因型频率在高分化组、中分化组、低分化组、未分化组组与对照组之间有统计学差异(P均 < 0.01)。 His72Tyr (TT)基因型者患大肠癌的风险显著增加(ORa高 = 3.46;ORa中 = 6.06;ORa低 = 7.79;ORa未 = 11.02)。-11391G/A (AA)基因型者患大肠癌的风险也显著增加(ORa高 = 3.38;ORa中 = 6.22;ORa低 = 7.791;ORa未 = 11.41)。基因突变的协同分析发现 His72Tyr (TT)/ -11391G/A (AA)基因型者在高分化组、中分化组、低分化组、未分化组与对照组中的分布频率分别为39.51%、54.32%、59.88、67.90%和11.73%,经χ2检验有显著性差异(P < 0.01)。His72Tyr (TT)/ -11391G/A (AA)基因型者患大肠癌的风险显著增加(ORa高= 5.72;ORa中=12.09;ORa低 = 16.55;ORa未 = 26.93)。His72Tyr (TT)和-11391G/A (AA)基因型之间存在超相乘模型的交互作用(高分化至未分化组OR 1?鄢2均大于OR1 × OR2)。【结论】 NADPH氧化酶p22phox亚基基因His72Tyr (TT)和脂联素基因启动子-11391G/A (AA)基因型均是大肠癌的易患因素,基因多态性的交互作用增加了大肠癌的发病风险。
Abstract: 【Objective】 To investigate the interaction of polymorphisms of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunit p22phox gene His72Tyr and adiponectin gene promoter -11391G/A in colon carcinoma and its cellular differentiation degree. 【Methods】 668 patients with confirmed colon carcinoma from the First Affiliated Hospital of Xinxiang Medical University in China from July 2009 to December 2014 were divided into high differentiation group, middle differentiation group, low differentiation group and undifferentiation group, with 162 cases in each group, and 162 healthy persons as control group. No significant difference among the 5 groups in age, gender, ethnicity, birthplace and living habit was observed. The genetic polymorphisms of NADPH oxidase subunit p22phox gene His72Tyr and adiponectin gene promoter-11391G/A were analyzed by the technique of polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) in peripheral blood leukocytes of above-mentioned cases. 【Results】 The frequencies of His72Tyr (TT) and -11391G/A (AA) were 50.62% and 50.00% in high differentiation group, 64.20% and 64.81% in middle differentiation group, 69.75% and 69.75% in low differentiation group, 76.54% and 77.16% in undifferentiation group and 22.84% and 22.84% in control group respectively. Statistical tests showed significant difference in the frequencies among each group (all P < 0.01). The risk of colon carcinoma significantly increased in subjects with His72Tyr (TT) genotype (ORaH =3.46; ORaM = 6.06; ORaL = 7.79; ORaU = 11.02) and in those with-11391G/A (AA) genotype (ORaH = 3.38; ORaM = 6.22; ORaL = 7.79; ORaU = 11.41). Combined analysis of the polymorphisms showed that distribution frequency of His72Tyr(TT)/-11391G/A(AA) in high differentiation group, middle differentiation group, low differentiation group, undifferentiation group and control group were 39.51%, 54.32%, 59.88%, 67.90%, and 11.73%, respectively (P < 0.01). The people who carried with His72Tyr (TT)/-11391G/A(AA) had a high risk of colon carcinoma (ORaH = 5.72; ORaM = 12.09; ORaL = 16.55; ORaU = 26.93), and statistical analysis suggested a positive interaction in a super-multiplicative model between His72Tyr (TT) and -11391G/A(AA) in increasing the risk of colon carcinoma(OR1?鄢2>OR1 × OR2) in high differentiation-undifferentiation). 【Conclusion】 NADPH oxidase subunit p22phox gene His72Tyr (TT) and adiponectin gene promoter-11391G/A(AA) are the risk factors in colon carcinoma, and significant interactions between genetic polymorphisms of His72Tyr and -11391G/A added the risk of colon carcinoma.
