摘要
目的探讨过氧化物酶体增殖物激活受体α(PPARα)基因遗传多态rsl800206(c.484C〉G,L162V)与南方人群代谢综合征(MES)的相关性。方法收集2010年3月至2011年3月在我院进行健康体检的40~60岁人员共1184名,采用real—timePCR技术(TAQMAN技术)分析PPARtx基因遗传多态484C〉G的基因型分布及其与人群MES的相关性。结果该人群PPAR(x基因484C〉G三种基因型CC、CG及GG频率分别为91.4%、8.4%及0.2%,符合遗传平衡定律(Hardy—Weinberg,P=0.845)。与常见基因型CC相比,携带变异基因型CG+GG者表现为血糖[(5.82±1.59)mmol/L与(5.49±1.17)mmol/L,t=2.630,P=0.009]和低密度脂蛋白胆固醇[(3.53±1.03)mmol/L与(3.36±0.65)mmol/L,t=2.376,P=0.018]增高,以及高密度脂蛋白胆固醇[(1.56±0.35)mmol/L与(1.65±0.43)mmol/L,t=2.430,P=0.015]降低。在调整性别、年龄、教育程度和吸烟、饮酒等生活方式及体质量指数后,484G变异基因型CG+GG降低与南方人群MES显著相关(调整OR=1.89;95%CI=1.09~3.23,P=0.012)。结论PPARct基因的遗传变异rsl800206可作为我国南方人群MES独立的预测指标。
Objective To investigate the association between the peroxisome proliferator-activated receptor-a(PPARct) polymorphism rs1800206( c. 484C 〉 G,L162V) and the risk of metabolic syndrome(MES) .Methods There were 1184 subjects aged 40 -60 years recruited from our hospital between March 2010 and March 2011. The PPARot polymorphism 484C 〉 G was genotyped using TAQMAN assay by real-time PCR. The relationship between PPARα polymorphism and MES risk were investigated. Results The genotype frequencies were 91.4% ,8. 4% and 0. 2% for the PPARα CC ,CG and GG,respectively. This SNP was in Hardy-Weinberg equilibrium( P = 0. 845 ). Compared with the most common CC genotype, the variant genotypes ( CG + GG) had higher fasting glucose ( (5.82 ± 1.59) mmol/L vs ( 5.49 ± 1.17 ) mmol/L, t = 2. 630, P = 0. 009 ) and LDL-C levels ( ( 3.53 ± 1.03 ) mmol/L vs ( 3.36± 0. 65 ) mmol/L, t = 2. 376, P = 0. 018 ) and lower HDL-C levels ( ( 1.56 ±0. 35 ) mmol/L vs ( 1.65± 0.43 ) mmol/L, t = 2. 430, P = 0. 015 ). Furthermore, the 484G variant genotypes( CG + GG)was associated with the risk of MES after adjusting for age, gender, education, BMI and lifestyle ( smoking and alcohol status) ( adjusted OR = 1.89 ;95 % C1 = 1.09 - 3.23, P = 0. O12 ). Conclusion PPARet polymorphism rs1800206 is a significant independent predictor of the MES in Southern Chinese.
