摘要： 目的 探讨CCNH基因启动子区- 1SNP位点碱基变异对CCNH基因转录活性的影响。方法 通过PCR和定点突变技术,构建了含CCNH基因基础启动子及- 1G突变启动子,用双荧光素酶报告系统观察此SNP对CCNH基因启动子转录活性的影响。结果 在AD293细胞中, -1G突变启动子活性比CCNH基础启动子活性低26%（P<0.05）。结论 -1T→G碱基变异可显著降低CCNH基因启动子转录活性。

Abstract: Objective To study the effect of -1 site single nucleotide polymorphism ( SNP) on CCNH gene promoter transcription activity. Methods PCR and site-directed mutagenesis technology were used to construct CCNH basic promoter and -1G mutate promoter. Dual-Luciferase Reporter assay system was used to detect the transcription activity of constructed promoter. Results In AD293 cells, the activity of - 1G mutate type promoter was significantly lower than wild type -1T promoter（P<0.05）. Conclusion It is implied that SNP-1T→G base variation can decrease the transcription activity of CCNH gene promoter.
