Genome-wide analysis of methylation in rat fetal heart under hyperglycemia by methylation-dependent restriction site-associated DNA sequencing.

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
Diabetes mellitus causes an increased incidence of congenital heart malformations. However, the pathogenesis and potential epigenetic mechanism involved in this process are unclear. In this study, we used MethylRAD sequencing to compare changes in methylation levels in the genomic landscapes in the fetal heart in a rat model of hyperglycemia. Our results showed that methylation of CCGG/CCNGG sites were mostly enriched in intergenic regions, followed by intron, exon, upstream and the 5' and 3' untranslated regions. qRT-PCR results confirmed the MethylRAD sequencing findings, suggesting that abnormal CCGG/CCNGG methylation in the upstream region regulated gene expression. The differential methylation genes (DMGs) based on the CCGG and CCNGG sites in the upstream region were examined by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis. Gene Ontology indicated that the CCGG-based DMGs involved in biological process and function were mainly related to transcription and co-SMAD binding. The CCNGG-based DMGs were mainly related to transcription and cytokine-mediated signaling pathways. Kyoto Encyclopedia of Genes and Genomes analysis indicated that CCGG-based DMGs were mainly involved in the Wnt signaling and TGF-β signaling pathways. CCNGG-based DMGs were involved in the TNF signaling and apoptosis pathways. These genes may play dominant roles in cardiomyocyte apoptosis and heart disease and require further study. These genes may also serve as potential molecular targets or diagnostic biomarkers for heart malformations under hyperglycemia.
