Polymorphisms in promoter region of TNF-alpha gene were shown to interfere with the transcriptional activity of the gene resulting in the production of different levels of TNF-alpha product suggesting their involvement in susceptibility or severity of many inflammatory diseases. We set up a case-control study consisting of 117 COPD (Chronic Obstructive Pulmonary Disease), 62 DB (bronchiectasis) patients and two control groups (109 smokers without COPD-healthy smokers control group and 212 general population subjects) to evaluate involvement of TNF-alpha gene polymorphisms in the abovementioned diseases in a homogeneous population.
The novel methodology of the NanoChip Molecular Biology Workstation (MBW Nanogen http://www.nanogen.com) was employed to genotype the 5 promoter SNPs.
Genotype frequencies of the 5 SNPs showed no significant difference between the COPD and DB patient groups and the healthy smokers group. Statistical difference (p=0.043) was only revealed between the haplotype frequencies in COPD patients compared to the general population control group. The NanoChip MBW is an accurate method for SNP screening.
肿瘤坏死因子-α(TNF-α)基因启动子区域的多态性被证明会干扰该基因的转录活性,导致产生不同水平的TNF-α产物,这表明它们与多种炎症性疾病的易感性或严重程度有关。我们开展了一项病例对照研究,纳入117例慢性阻塞性肺疾病(COPD)患者、62例支气管扩张症(DB)患者以及两个对照组(109名无COPD的吸烟者——健康吸烟者对照组和212名普通人群受试者),以评估在同一人群中TNF-α基因多态性与上述疾病的相关性。
采用NanoChip分子生物学工作站(MBW Nanogen,网址:http://www.nanogen.com)的新方法对5个启动子单核苷酸多态性(SNP)进行基因分型。
COPD患者组、DB患者组与健康吸烟者组之间,5个SNP的基因型频率无显著差异。仅在COPD患者与普通人群对照组的单倍型频率之间发现有统计学差异(p = 0.043)。NanoChip MBW是一种准确的SNP筛查方法。
