Abstract
Small interfering RNAs (siRNAs) represent RNA duplexes of 21 nucleotides in length that inhibit gene expression. We have used the human gene-external 7S K RNA promoter for synthesis of short hairpin RNAs (shRNAs) which efficiently target human lamin mRNA via RNA interference (RNAi). Here we demonstrate that orientation of the target sequence within the shRNA construct is important for interference. Furthermore, effective interference also depends on the length and/or structure of the shRNA. Evidence is presented that the human 7S K promoter is more activein vivothan other gene-external promoters, such as the human U6 small nuclear RNA (snRNA) gene promoter.Keywords
