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

backgroundVascular calcification is a detrimental aging pathology markedly accelerated in patients with chronic kidney disease. PLA (prelamin A) is a biomarker of vascular smooth muscle cell aging that accelerates calcification however the mechanisms remain undefined.

methodsVascular smooth muscle cells were transduced with PLA using an adenoviral vector and epigenetic modifications were monitored using immunofluorescence and targeted polymerase chain reaction array. Epigenetic findings were verified in vivo using immunohistochemistry in human vessels, in a mouse model of inducible prelamin A expression, and in a rat model of chronic kidney disease-induced calcification. Transcriptomic and chromatin immunoprecipitation followed by sequencing analyses were used to identify gene targets impacted by changes in the epigenetic landscape. Molecular tools and antibody arrays were used to monitor the effects of mineral dysregulation on heterochromatin, inflammation, aging, and calcification.

resultsHere, we report that depletion of the repressive heterochromatin marks, H3K9me3 (histone H3, lysine 9, trimethylation) and H3K27me3 (histone H3, lysine 27,trimethylation), is an early hallmark of vascular aging induced by both nuclear lamina dysfunction and dysregulated mineral metabolism, which act to modulate the expression of key epigenetic writers and erasers. Global analysis of H3K9me3 and H3K27me3 marks and pathway analysis revealed deregulation of insulin signaling and autophagy pathways as well as cross-talking DNA damage and NF-κB (nuclear factor κB) inflammatory pathways consistent with early activation of the senescence-associated secretory phenotype. Expression of PLA in vivo induced loss of heterochromatin and promoted inflammation and osteogenic differentiation which preceded aging indices, such as DNA damage and senescence. Vessels from children on dialysis and rats with chronic kidney disease showed prelamin A accumulation and accelerated loss of heterochromatin before the onset of calcification.

conclusionsDysregulated mineral metabolism drives changes in the epigenetic landscape and nuclear lamina dysfunction that together promote early induction of inflammaging pathways priming the vasculature for downstream pathological change.
