摘要:

研究谷胱甘肽-S-转移酶 (glutathione S-transferase, GST)M1和T1基因多态性与支气管哮喘(asthma bronchial)的关系。采取聚合酶链反应对60名支气管哮喘患者和60名正常对照进行了GSTM1和GSTT1基因非缺失(+)和缺失(0)等位基因分布频率研究。结果表明,与对照组相比,支气管哮喘患者GSTM1基因缺失的纯合子(0/0)频率(81.2%)显著升高(χ2=32.46,P<0.001;wχ2=28.75,P<0.001)。对于GSTT1也得到类似资料。而支气管哮喘患者GSTT1基因缺失等位基因(0/0)频率(71.7%)比对照组(11.7%)显著升高(χ2=26.72,P<0.001;wχ2=35.75,P<0.001)。表明GSTM1、GSTT1缺失等位基因纯合性在哮喘患者中最有特征性的。GSTM1 0/0、GSTT1 0/0结合的频率患者组为61.7%,对照组仅为1.7%(χ2=27.3,P<0.001)。提示GSTM1和GSTT1基因多态性与哮喘有显著性关联,两个基因的突变可以被视为发生支气管哮喘遗传风险因子。

Abstract: To study the association of genes polymorphisms in glutathione S-transferase M1 and T1 with asthma bronchial. The distribute frequency of allele(+) and allele(o) between GSTM1 and GSTT1 of 60 patients asthma bronchial and 60 control groups in Tangshan was studied with PCR. The result shown GSTM1 deficiency allele(0/0) frequency of asthma bronchial was 81.2%, which showed significantly higher(χ2=32.46, P<0.001; wχ2=28.75,P<0.001) than the control groups; GSTT1 was similar to GSTM1. But GSTT1 zero allele(0/0) frequency of asthma bronchial were 71.7%, which were significantly higher (χ2=26.72, P<0.001; wχ2=35.75, P<0.001) than the control groups(11.7%). Zero allele of GSTM1 and GSTT1 were showed the most features in the asthma bronchial. Associated significantly in the genes polymorphisms of GSTM1 and GSTT1 with asthma bronchial, their genes mutation may be the genetic risk factor of asthma bronchial.
