Effect of -1 SNP on CCNH promoter activity / 基础医学与临床

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 that of wild type-1T promoter(P
