目的:探讨过氧化物酶增殖物激活受体( peroxisome proliferator activated receptor , PPAR)γ2基因Pro12Ala及解偶联蛋白(uncoupling protein 2, UCP2)基因3′非翻译区(3′-untranslated region,3′-UTR)处45bp的插入/缺失(insertion/deletion, I/D)复合变异对中国汉族人群2型糖尿病发生的影响。方法应用聚合酶链反应-限制性片段长度多态性( PCR-RFLP)方法及聚合酶链反应-片段长度多态性(PCR-FLP)方法,分别对PPARγ2基因Pro12Ala及UCP2基因3′-UTR处45bp的I/D变异进行检测。490例2型糖尿病患者,正常对照组585例。结果⑴Pro12Ala( P12A)基因型分布在病例组与对照组间差异无统计学意义( P >0.809);病例组中携带A12等位基因者腰围(94.6±11.8cm)明显大于P12P基因型腰围(91.5±11.8cm),( t =2.199, P =0.028);携带A12等位基因者口服葡萄糖耐量试验( oral glucose tolerance test , OGTT)0.5h、1 h、2 h胰岛素均明显低于P12 P基因型( Z =2.222, P <0.05;Z =2.051, P <0.05;Z =2.079, P <0.05)。⑵UCP2基因3′UTRI/D多态性3种基因型在病例组及对照组间的频率分布差异无统计学意义( P >0.05);对照组中携带I等位基因者OGTT半小时胰岛素明显高于DD基因型( Z =1.997, P <0.05)。⑶携带Pro/Ala+Del/Del基因型组合与2型糖尿病的关系最密切( OR=1.22,95%CI 1.078~1.386)。结论虽然单一的PPARγ2基因Pro12Ala及UCP2基因3′-UTR处45bp的I/D变异与2型糖尿病的发生无关,但这两种微效基因加起来则形成了明显的2型糖尿病发生的表型效应。
目的:探討過氧化物酶增殖物激活受體( peroxisome proliferator activated receptor , PPAR)γ2基因Pro12Ala及解偶聯蛋白(uncoupling protein 2, UCP2)基因3′非翻譯區(3′-untranslated region,3′-UTR)處45bp的插入/缺失(insertion/deletion, I/D)複閤變異對中國漢族人群2型糖尿病髮生的影響。方法應用聚閤酶鏈反應-限製性片段長度多態性( PCR-RFLP)方法及聚閤酶鏈反應-片段長度多態性(PCR-FLP)方法,分彆對PPARγ2基因Pro12Ala及UCP2基因3′-UTR處45bp的I/D變異進行檢測。490例2型糖尿病患者,正常對照組585例。結果⑴Pro12Ala( P12A)基因型分佈在病例組與對照組間差異無統計學意義( P >0.809);病例組中攜帶A12等位基因者腰圍(94.6±11.8cm)明顯大于P12P基因型腰圍(91.5±11.8cm),( t =2.199, P =0.028);攜帶A12等位基因者口服葡萄糖耐量試驗( oral glucose tolerance test , OGTT)0.5h、1 h、2 h胰島素均明顯低于P12 P基因型( Z =2.222, P <0.05;Z =2.051, P <0.05;Z =2.079, P <0.05)。⑵UCP2基因3′UTRI/D多態性3種基因型在病例組及對照組間的頻率分佈差異無統計學意義( P >0.05);對照組中攜帶I等位基因者OGTT半小時胰島素明顯高于DD基因型( Z =1.997, P <0.05)。⑶攜帶Pro/Ala+Del/Del基因型組閤與2型糖尿病的關繫最密切( OR=1.22,95%CI 1.078~1.386)。結論雖然單一的PPARγ2基因Pro12Ala及UCP2基因3′-UTR處45bp的I/D變異與2型糖尿病的髮生無關,但這兩種微效基因加起來則形成瞭明顯的2型糖尿病髮生的錶型效應。

Objective To investigate the additive effects of uncoupling protein 2(UCP2) gene 3′-untranslated region(3′-UTR) 45-base pair insertion/deletion( I/D) variation and peroxisome proliferator activated receptor( PPAR)γ2 gene Pro12Ala variation on type 2 diabetes(T2DM) in Chinese Han popula-tion.Methods The UCP2 gene 3′-UTR I/D variation and PPARγ2 gene Pro12Ala variation were exam-ined by polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) in 490 type 2 dia-betes subjects and in 585 control subjects .The additive effects of the two gene mutations were analyzed . Results ⑴The frequency of PPARγ2 gene Pro12Ala variation in type 2 diabetes was not significantly dif-ferent from that in control subjects.(χ2 =0.058, P =0.809).In T2DM group, A12 allele carriers had larger waist circumference than Pro12Pro genotype carriers;Glucose stimulated insulin secretion by oral glu-cose tolerance test (OGTT) was significantly lower in carriers of the Ala12Ala or Pro12Ala genotype com-pared with Pro12Pro genotype.( Z =2.222, P =0.026; Z =2.051, P =0.040; Z =2.079, P =0.038 ) .⑵There wasn't significant difference among 3 genotypes with 3′-UTR I/D variation in UCP2 gene (χ2 =2.311 , P =0.315 ) .In control group , Glucose stimulated insulin secretion by oral glucose tolerance test ( OGTT) was significantly higher in carriers of the I/D or I/I genotype compared with D/D genotype ( Z =1.997 , P =0.046 ) .⑶The genotype carriers with Pro/Ala +Del/Del were the greatest relation to T2DM (OR=1.22, 95%CI 1.078~1.386).Conclusion Though the UCP2 gene mutation alone or the PPARγ2 gene mutation alone is not associated with T 2DM, the possible additive effects of the two micro genes increase the occurring of T 2DM.
