    • Isolated polynucleotides comprising at least 14 nucleotides of SEQ ID NO:6 of a pre-proendothelin promoter which comprise at least 2 consecutive sequences being positioned next to at least one nucleotide position selected from the group consisting of at least one nucleotide of SEQ ID NO:46, 47, 52, 49, 50, 53 and 54, which is mutated as compared to SEQ ID NO:6 such that when the isolated polynucleotide is integrated into the PPE-1 promoter and placed upstream of a luciferase coding sequence the expression level of the luciferase coding sequence is upregulated or downregulated as compared to when SEQ ID NO:6 is similarly integrated into the PPE-1 promoter and placed upstream of the luciferase coding sequence. Also provided are nucleic acid constructs comprising same, methods of using same and pharmaceutical compositions comprising same for increasing or decreasing expression of a polynucleotide of interest in endothelial and non-endothelial cells.
    • 包含前内皮素启动子的SEQ ID NO:6至少14个核苷酸的分离的多核苷酸,其包含至少两个连续序列,位于选自SEQ ID NO:6的至少一个核苷酸的至少一个核苷酸位置旁边。 46,47,52,49,50,53和54,其与SEQ ID NO:6相比突变,使得当分离的多核苷酸整合到PPE-1启动子中并置于萤光素酶编码序列的上游时,其表达水平 与SEQ ID NO:6类似地整合到PPE-1启动子中并置于荧光素酶编码序列上游的荧光素酶编码序列的上调或下调。 还提供了包含其的核酸构建体,使用它们的方法和包含其的药物组合物,用于增加或减少内皮和非内皮细胞中感兴趣的多核苷酸的表达。
