Expression profiles and bioinformatic analysis of microRNAs in myocardium of diabetic cardiomyopathy mice.
Article in Genes & genomics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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) can regulate expression of target genes at post transcriptional level, and mediate the pathophysiological process of many diseases.
objectiveThe study will illuminate the miRNA expression profiles of diabetic cardiomyopathy (DCM), seeking probable biomarkers of DCM at early stage and determining a target for the treatment of DCM.
methodsDb/db mice were used as an animal model of type 2 diabetes mellitus. At 22 weeks of age, cardiac function was evaluated by echocardiography, and the structural changes in myocardium were evaluated by HE staining and TEM. The miRNA expression profiles were detected using miRNA sequencing and differentially expressed miRNAs were validated by real-time PCR. Bioinformatic analysis was used to analyze target genes of these miRNAs and relevant pathways in DCM.
resultsThe results showed that 40 miRNAs were differentially expressed, including 28 upregulated miRNAs and 12 downregulated miRNAs. GO and KEGG pathway analysis showed that the target genes of up-regulated miRNAs were involved in 66 pathways, including Wnt, p53 and calcium signaling pathways, as well as FOXO and apoptosis signaling pathways, etc. The target genes of down-regulated miRNAs were involved in 68 pathways, including mitophagy, Ras and MAPK signaling pathways, etc. Moreover, some differentially expressed miRNAs were found in myocardium of DCM for the first time, such as miR-7225-5p, miR-696, miR-3470a, miR-3470b, miR-6240, miR-6538, miR-5128, miR-1195, miR-203-3p and miR-330-5p.
conclusionsIt is hoped that a few novel molecular pathways or targets of treatment for DCM would be found through understanding the expression features of miRNAs in diabetic myocardium.
