A multi-shRNA vector enhances the silencing efficiency of exogenous and endogenous genes in human cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
RNA interference (RNAi) is a powerful technology for suppressing gene function. In most studies, small interfering RNAs (siRNAs) consist of one short hairpin RNA (shRNA) and, therefore, are often unable to achieve loss-of-function of their target genes. In the current study, an RNAi vector containing three shRNAs under the control of three RNA polymerase III U6 promoters was constructed. RNAi vectors containing one or two shRNAs were generated for comparisons. A pilot study targeting exogenously expressed DsRed in the HEK293 cell line revealed promising effects and a high selectivity for the multi-shRNA RNAi vector. Akt2 is constitutively expressed in cultured SKOV3 human ovarian cancer cells, and the multi-shRNA RNAi vector showed a strong efficiency for downregulating the expression of Akt2 in these cells, with no apparent interferon response. In addition, the Akt2-3shRNA vector, containing three shRNAs targeting Akt2, showed the best effect of all the shRNA vectors in reversing paclitaxel-induced resistance in SKOV3 cells. This study developed a widely applicable resource for enhancing the efficiency of gene silencing and a novel technique for performing complex loss-of-function screens in mammalian cells.
