Transcriptional gene silencing has been reported with siRNA targeting the promoter region of genes. We tested several siRNAs directed against the human VEGF promoter. Of these, siVFp(-992) exhibited > or =50% suppression of VEGF production in two human cell lines. To determine the specificity of this siRNA-mediated suppression, plasmids were prepared to express a luciferase reporter under the control of VEGF promoters featuring wild-type, mutated, or deleted target sequences. siRNA transfection  ...[more]
