Online promoter analysis tools of TESS and Genomax were used to search possible sequence of transcriptional start site and message RNA sequence were fished out. 利用启动子分析软件在人类转录因子数据库中搜索可能存在的顺式结构;
There is a hypermethylation sequential basis in the upstream region from the transcriptional start site of IRX1 gene. IRX1基因转录起始点上游存在高甲基化结构基础。
