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

backgroundMicroRNAs (miRNAs) are post-transcriptional regulators that influence gene expression and dysregulation has been linked to the pathogenesis of ulcerative colitis (UC). The current study investigated the regulatory axis between hsa-mir-10a-5p and RNF186 in UC inflammation.

methodsRNF186 was identified as a target of hsa-mir-10a-5p by bioinformatics prediction and dual-luciferase reporter assay. A UC cell model was established by lipopolysaccharide (LPS) stimulation of HT-29 intestinal epithelial cells. Gain-of-function (overexpression) and loss-of-function (knockdown) experiments targeting hsa-mir-10a-5p and RNF186 were performed to assess function and mRNA and protein expression were measured by quantitative real-time PCR (qRT-PCR) and western blotting. Apoptosis was quantified by flow cytometry.

resultshsa-mir-10a-5p was shown to bind to the 3’UTR of RNF186 by dual-luciferase assay and a negative correlation shown between the expression of hsa-mir-10a-5p and RNF186 in a UC model. hsa-mir-10a-5p overexpression downregulated RNF186 expression, reduced pro-inflammatory cytokines, TNF-α, IL-6, and attenuated apoptosis. hsa-mir-10a-5p knockdown upregulated RNF186 expression and exacerbated inflammatory responses. RNF186 knockdown produced a similar anti-inflammatory effect to that observed with hsa-mir-10a-5p overexpression. RNF186 overexpression increased inflammatory damage.

conclusionhsa-mir-10a-5p negatively regulated RNF186 and modulated the inflammation characteristic of UC. The hsa-mir-10a-5p/RNF186 axis may be a novel therapeutic target for UC.
