1 · What the graph read from it

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.

2 · The registry

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

Small interfering RNA (siRNA) and short hairpin RNA (shRNA) targeting different regions of transforming growth factor beta1 (TGF-beta1) mRNA were designed and the silencing effect was determined after transfection into immortalized rat liver stellate cells (HSC-T6). There was not only significant decrease in TGF-beta1, tissue inhibitor of metalloproteinase 1 (TIMP-1), alpha-smooth muscle actin (alpha-SMA) and type I collagen after transfection with TGF-beta1 siRNAs, but also synergism in gene silencing when siRNAs targeting two different start sites were used as a pool for transfection. The two siRNA sequences which efficiently inhibited TGF-beta1 gene expression were converted to shRNAs via cloning into the pSilencer1.0. There was significant decrease in TGF-beta1 and TIMP-1 when HSC-T6 cells were transfected with pshRNA targeting the same regions of TGF-beta1 mRNA as siRNAs. Furthermore, TGF-beta1 gene silencing in HSC-T6 cells significantly decreased the levels of inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1beta). In conclusion, both siRNA and shRNA showed sequence-specific and dose dependent TGF-beta1 gene silencing and have the potential to treat liver fibrosis.
