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

objectiveMast cells-derived extracellular vesicles (EVs) play vital roles in various physiological and pathophysiological conditions. However, the cargoes of mast cells-derived EVs in asthma have not been established. Here, we set to identify the role of microRNA-21 (miRNA-21) from mast cells-derived EVs in ozone- and lipopolysaccharide (LPS)-induced mouse airway epithelial cells (MIC-iCell-a006 cells) and asthmatic mice.

methodsAfter ozone or LPS treatment, MIC-iCell-a006 cells were subjected to a microarray analysis to screen differentially expressed miRNAs, and then co-cultured with EVs. miR-21 was silenced in cells, followed by CCK-8, scratch, and Transwell assays. Mice were challenged with ovalbumin, and antioxidant enzymes and inflammatory cell infiltration were assessed after EVs and miR-21 inhibitor treatments. The relation between miR-21 and DDAH1 was evaluated by Dual-luciferase assay, and changes in Wnt/β-catenin pathway related proteins were examined by western blot. Finally, the involvement of the DDAH1/Wnt/β-catenin axis in miR-21-mediated oxidative stress and inflammation was verified by rescue experiments.

resultsmiR-21 expression was upregulated in MIC-iCell-a006 cells induced by ozone or LPS. miR-21 was enriched in mast cells-derived EVs, and EVs increased miR-21 expression in MIC-iCell-a006 cells. miR-21 inhibitor increased cell activity and alleviated oxidative stress and inflammation. In asthmatic mice, miR-21 expression was increased, and EVs decreased antioxidant enzymes and increased inflammatory cells, whose effects were reversed by miR-21 knockdown. miR-21 targeted DDAH1 to mediate the Wnt/β-catenin signaling, and down-regulation of DDAH1 inhibited the action of miR-21 inhibitor.

conclusionThe miR-21 secreted from mast cells-derived EVs promotes oxidative stress and inflammatory responses in asthmatic mice via the DDAH1/Wnt/β-catenin signaling axis.
