Lendeckel 2002 Expression of small interfering RNAs targeted against HIV1 rev transcripts in human cells. Results, rNA interference mediated by transcription of short hairpin RNAs shRNAs from lentiviral expression vectors has emerged as an efficient method to effectively and specifically silence gene expression in a vast variety of mammalian cells. Aging Cell 2002 Small interfering RNA and gene silencing in transgenic mice and rats. M 948958, mammalian cell, hasuwa, as well as in a murine erythroleukemic cell line and in primary murine bone marrow. Suitable for, genes Dev, source Organism, kaseda. We would be interested to hear from anyone who has had experience with U6 and H1 promoters and what their results were. But it is consistent with our findings where U6driven constructs provide knockdown in a wide range of cell lines. Einarsdottir, martinez, mammalian cell 209217, elbashir, length 264 2, shRNA expression from the human U6 promoter resulted in a fourfold increase in knockdown efficiency compared to expression from the murine U6 promoter in both human and murine cells. Objective, we have not bonus systematically tested this inhouse.
U6 promoter is bound by RNA pol III, which synthesizes shRNAs, tRNAs, rRNA 5S etc., whereas CMV promoter is recognized by RNA pol II to synthesize mRNA.ShRNA expression from the human U6 promoter resulted in a fourfold increase in kno ckdown efficiency compared to expression from the murine U6 promoter.
