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

Novel molecular mechanisms of the pathophysiology of heart failure (HF) are continuously being discovered, including epigenetic regulation. Among epigenetic marks, the role of DNA hypomethylation in shaping heart morphology and function in vivo and the pathogenesis of cardiomyopathy and/or HF, especially in adults, has not been clearly established. Here we show that the strong expression of DNA methyltransferase 1 (Dnmt1) is obviously downregulated in the WT adult rat heart with age. By contrast, the expression of Dnmt1 is upregulated suddenly in heart tissues from pressure overload-induced HF mice and adriamycin-induced cardiac injury and HF mice, consistent with the increased expression of Dnmt1 observed in familial hypertrophic cardiomyopathy (FHCM) patients. To further assess the role of Dnmt1, we generated myocardium-specific Dnmt1 knockout (Dnmt1 KO) rats using CRISPR-Cas9 technology. Echocardiographic and histopathological examinations demonstrated that Dnmt1 deficiency is associated with resistance to cardiac pathological changes and protection at the global and organization levels in response to pathological stress. Furthermore, Dnmt1 deficiency in the myocardium restricts the expressional reprogramming of genes and activates pathways involved in myocardial protection and anti-apoptosis in response to pathological stress. Transcriptome and genome-wide DNA methylation analyses revealed that these changes in regulation are linked to alterations in the methylation status of genes due to Dnmt1 knockout. The present study is the first to investigate in vivo the impact of genome-wide cardiac DNA methyltransferase deficiency on physiological development and the pathological processes of heart tissues in response to stress. The exploration of the role of epigenetics in the development, modification, and prevention of cardiomyopathy and HF is in a very preliminary stage but has an infinite future.
