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

backgroundAs mechanisms of neoplasia in patients with ulcerative colitis (UC) remain poorly understood, we sought to identify pathways of carcinogenesis in this high-risk population.

methodsMicroRNA (miRNA) and mRNA expression was examined in nondysplastic rectosigmoid mucosa from UC patients with (n = 19) or without remote colon neoplasia (n = 23). We developed a method to identify miRNA-regulated pathways based on differentially expressed miRNAs and their putative mRNAs targets in the same samples. One key pathway identified in the analysis, miR-4728-3p regulation of focal adhesion signaling was further evaluated in vitro and through examination of expression in UC-cancers.

resultsThere were 101 significantly up-regulated and 98 down-regulated miRNAs (adjusted P < 0.05) in the rectal mucosa of UC patients harboring proximal neoplasia. Bioinformatic analysis identified miR-4728-3p as a regulator of 3 proteins involved in focal adhesion signaling, CAV1, THBS2, and COL1A2. Real-time PCR validated down-regulation of miR-4728-3p in nondysplastic tissue remote from UC-neoplasia and in UC-associated colon cancers. miR-4728-3p transfection into colon cancer cells down-regulated expression levels and decreased luciferase activities in cells expressing a wild type 3' untranslated region compared with a mutant 3' untranslated region for all 3 genes. Exogenous transfected miR-4728-3p also delayed wound healing and decreased formation of focal adhesion complexes.

conclusionsPatients with long-standing UC who harbor neoplasia can be identified based on miRNA and mRNA profiles in nondysplastic tissue. Using a method to analyze miRNA and mRNA expression from the same tissues, we identified that miR-4728-3p is likely an important tumor suppressor in UC-associated colon carcinogenesis.
