MiR-489 aggravates H2O2-induced apoptosis of cardiomyocytes via inhibiting IGF1.
Article in Bioscience reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Myocardial infarction (MI) is a major type of cardiovascular disorder worldwide. In the present study, we established a new microRNA (miRNA)-mRNA cross-talk network by integrating data obtained from The National Center for Biotechnology Information Gene Expression Omnibus (NCBI GEO). In addition, functional assays, including Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and Gene Ontology (GO) analyses, were conducted using the Database for Annotation, Visualization, and Integration Discovery (DAVID). In our study, we generated a new differentially expressed miRNA (DEmiRNA)-differentially expressed gene (DEG) cross-talk network of MI composed of three miRNA (miR-489, miR-375, and miR-142-3p) nodes and 163 mRNA nodes. In vitro experiments demonstrated that miR-489 expression was increased in H2O2-treated H9c2 cardiomyocytes in vitro, mimicking myocardial injury. We observed that down-regulation of miR-489 reduced H2O2-induced apoptosis, while overexpression of miR-489 had the opposite effects, as revealed by flow cytometry and Western blot analyses. Furthermore, we confirmed the relationship between miR-489 and IGF1 through double luciferase reporter gene assays, which partly explains the antiapoptotic mechanism of miR-489. In conclusion, the experimental results of the present study could provide important clues for investigating the mechanism of MI.
