Expression of miR‑542‑3p in osteosarcoma with miRNA microarray data, and its potential signaling pathways.

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
Osteosarcoma (OS) is the most common pediatric primary bone tumor, with high malignancy rates and a poor prognosis following metastasis. At present, the role of microRNA (miR)‑542‑3p in OS remains to be elucidated. The purpose of the present study was to investigate the expression level of miR‑542‑3p in OS, and its potential molecular mechanisms, via a bioinformatics analysis. First, the expression of miR‑542‑3p in OS based on the continuous variables of the Gene Expression Omnibus database and PubMed was studied. Subsequently, the potential target genes of miR‑542‑3p were predicted using gene expression profiles and bioinformatics software. On the basis of the Database for Annotation, Visualization and Integrated Discovery, version 6.8, a study of gene ontology (GO) enrichment and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway knowledge base was conducted to explore the biological value of miR‑542‑3p in OS. Finally, the protein‑protein interaction (PPI) network was completed using the STRING database. The expression of miR‑542‑3p in OS was revealed to be significantly higher compared with that in normal tissue. In total, 1,036 target genes of miR‑542‑3p were obtained. The results of the GO enrichment analysis revealed that the significant terms were 'bone development', 'cell cycle arrest' and 'intracellular signal transduction'. The results of the KEGG analysis revealed the highlighted pathways that were targeted to miR‑542‑3p, including the sphingolipid signaling pathway (P=3.91x10‑5), the phosphoinositide 3‑kinase (PI3K)‑AKT serine/threonine kinase (AKT) signaling pathway (P=3.17x10‑5) and the insulin signaling pathway (P=1.04x10‑5). The PPI network revealed eight hub genes: Ubiquitin‑60S ribosomal protein L40, Ras‑related C3 botulinum toxin substrate, mitogen‑activated protein kinase 1, epidermal growth factor receptor, cystic fibrosis transmembrane conductance regulator, PI3K regulatory subunit 1, AKT1, and actin‑related protein 2/3 complex subunit 1A, which may be the key target genes of miR‑542‑3p in OS. Taken together, these results have demonstrated that miR‑542‑3p was overexpressed in OS. The potential target genes and biological functions of miR‑542‑3p may provide novel insights into the differentially expressed genes that are involved in OS.
