Multiple microRNAs derived from chemically synthesized precursors regulate thrombospondin 1 expression.

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
Thrombospondin 1 (THBS1) is a secreted protein with a variety of biological functions, including a potent anti-angiogenic activity and activation of latent transforming growth factor beta (TGF-β). In many human cancers it is expressed at low levels, although mutations in the THBS1 gene have been rarely reported. Instead, the loss of THBS1 expression has been proposed to be due to transcriptional and post-transcriptional deregulations. In a systematic screen of predicted microRNA (miRNA) binding sites in the THBS1 3' untranslated region (UTR) we employed chemically synthesized pre-miRNAs-a new class of pre-miRNA mimics-to show that several miRNAs (let-7a, miR-18a, miR-29b, miR-194, and miR-221) can modulate THBS1 expression at the post-transcriptional level. Sequence-specific downregulation of THBS1 by let-7a, miR-18a or by a small interfering RNA induced TGF-β1 and SMAD4 transcript levels. Ectopic expression of latent TGF-β1 reduced THBS1 protein expression and was associated with increased expression of let-7a, let-7-b, and miR-18a in cells. These data suggest an inverse correlation of THBS1 and latent TGF-β1 expression levels possibly involving miRNAs.
