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

objectiveEarly postnatal life is considered as a critical time window for the determination of long-term metabolic states and organ functions. Extrauterine growth restriction (EUGR) causes the development of adult-onset chronic diseases, including pulmonary hypertension. However, the effects of nutritional disadvantages during the early postnatal period on pulmonary vascular consequences in later life are not fully understood. Our study was designed to test whether epigenetics dysregulation mediates the cellular memory of this early postnatal event. METHODS AND

resultsTo test this hypothesis, we isolated pulmonary vascular endothelial cells by magnetic-activated cell sorting from EUGR and control rats. A postnatal insult, nutritional restriction-induced EUGR caused development of an increased pulmonary artery pressure at 9 weeks of age in male Sprague-Dawley rats. Methyl-DNA immune precipitation chip, genome-scale mapping studies to search for differentially methylated loci between control and EUGR rats, revealed significant difference in cytosine methylation between EUGR and control rats. EUGR changes the cytosine methylation at approximately 500 loci in male rats at 9 weeks of age, preceding the development of pulmonary hypertension and these represent the candidate loci for mediating the pathogenesis of pulmonary vascular disease that occurs later in life. Gene ontology analysis on differentially methylated genes showed that hypermethylated genes in EUGR are vascular development-associated genes and hypomethylated genes in EUGR are late-differentiation-associated and signal transduction genes. We validated candidate dysregulated loci with the quantitative assays of cytosine methylation and gene expressions.

conclusionThese results demonstrate that epigenetics dysregulation is a strong mechanism for propagating the cellular memory of early postnatal events, causing changes in the expression of genes and long-term susceptibility to pulmonary hypertension, and further providing a new insight into the prevention and treatment of EUGR-related pulmonary hypertension.
