Chemokine receptor delta32 Turkish people
2009/6/17
Aim:Delta32 polymorphism in the chemokine receptor 5 (CCR5) gene affects human immune deficiency virus type 1 (HIV-1) entry, transmission, and outcome. The aim of this study was to determine the allel...
组织蛋白酶D基因C224T多态与散发阿尔茨海默氏病的关联研究The C224T Polymorphism in the Cathepsin D Gene is not Associated with Sporadic Alzheimer’s Disease in Chinese
阿尔兹海默氏病 组织蛋白酶基因 多态性 限制性片段长度
2008/1/10
摘要
组织蛋白酶D(Cathepsin D)是一种细胞核内体/溶酶体内的门冬酰胺蛋白酶。它有可能通过剪切淀粉样前体蛋白参与阿尔茨海默氏病(Alzheimer’s disease, AD)相关的神经退化。在以德国人为对象中的研究显示组织蛋白酶D基因(CTSD)C224T多态与AD发病风险紧密相关。然而,此结果未能在另一些群体中得到重复。为此,我们通过聚合酶链反应-限制性片段长度多态性方法分析了C...
山东胃癌高低发人群Lewis基因多态性分析Analysis of Lewis Gene Polymorphism in High and Low Incidence Area of Gastric Cancer in Shandong Province
胃癌 高低发人群 Lewis基因多态性
2007/12/30
摘要应用PCR产物直接测序的方法,检测山东省胃癌高发的临朐人群和低发的苍山人群中Lewis基因多态性T59G的分布,旨在探讨山东临朐和苍山地区胃癌发病率显著不同的内在原因,为阐明临朐地区胃癌高发的机制提供实验依据。结果表明,T59G突变个体在临朐和苍山人群中的分布频率分别为34.5%和31.6%,差别无统计学意义,P>0.05,OR为1.14 (95% CI,0.59~2.19)。提示就此点突变而...
Graves病患者TNFβ基因微卫星多态性分析Analysis of TNFβ Gene Microsatellite Polymorphism in Graves Disease
淋巴毒素 微卫星多态性 格雷夫斯病
2007/12/7
摘要为研究Graves病患者(简称GD)TNF(tumor necrosis factor)β基因内含子1的微卫星多态性(TNFc),应用聚合酶链反应(PCR)技术和聚丙烯酰胺凝胶电泳分析Graves病实验组和正常对照组的基因频率和基因型频率。结果可见,TNFc微卫星多态性含有两个等位基因及3种基因型,Graves病实验组的TNFc2基因频率高于正常对照组,有显著性差异 (χ2=4.02,P<0....
