摘要背景:人谷胱甘肽 S-转移酶 omega-1 (hGSTO1) 具有单甲基胂酸 (MMAv) 还原酶活性。最近的研究表明,hGSTO1 中的两个多态性(E155 缺失和 E208K)可能与无机砷代谢的个体间差异有关。由于目前还没有针对这些 hGSTO1 多态性的有用的基于 PCR 的基因分型方法,并且非洲和亚洲人群中 hGSTO1 多态性的数据不足,本研究的目的是开发一种基于 PCR 的 E155del 和 E208K 基因分型方法,并调查这两种多态性在 Ovambo 和日本人群中的等位基因频率。方法:分别采用配对两对引物分析和PCR-限制性片段长度多态性检测E155del和E208K多态性。结果:在 Ovambo (n=144) 和日本人 (n=144) 人群中研究了 hGSTO1 多态性的等位基因频率。对于 E155del,Ovambo 和日本受试者的突变频率分别为 0.000 和 0.017,与其他人群相似。至于E208K多态性,在Ovambo或日本受试者中未发现突变等位基因。结论:本研究开发了一种基于 PCR 的 hGSTO1 基因分型方法,可应用于大多数地点的大量个体。临床化学实验室医学 2007;45:621–4。
Abstract Background: Human glutathione S-transferase omega-1 (hGSTO1) has monomethylarsonate (MMAv) reductase activity. Recent study suggests that two polymorphisms (E155 deletion and E208K) in hGSTO1 can be related to inter-individual variations in inorganic arsenic metabolism. As useful PCR-based genotyping methods for these hGSTO1 polymorphisms are not available and data on hGSTO1 polymorphism in African and Asian populations are insufficient, the aim of the present study was to develop a PCR-based genotyping method for E155del and E208K, and to investigate the allele frequencies of these two polymorphisms in Ovambo and Japanese populations. Methods: The E155del and E208K polymorphisms were detected using confronting two-pair primers analysis and PCR-restriction fragment length polymorphism, respectively. Results: Allele frequencies for the hGSTO1 polymorphisms were investigated in Ovambo (n=144) and Japanese (n=144) populations. For E155del, the mutation frequency in Ovambo and Japanese subjects was 0.000 and 0.017, respectively, similar to those for other populations. As for E208K polymorphism, no mutation allele was found in Ovambo or Japanese subjects. Conclusions: The present study developed a PCR-based hGSTO1 genotyping method that could be applied to a large number of individuals at most locations. Clin Chem Lab Med 2007;45:621–4.
