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

INTRODUCTION AND

aimsThe connection between oral and systemic diseases is receiving increasing attention. Pulpitis is an infectious disease, and its potential impact on the systemic system deserves further investigation.

methodsA rat/mouse pulpitis model was utilized to explore the variations in bone morphogenetic protein 9 (BMP9) and lipopolysaccharide (LPS) concentrations within liver tissue and blood. Hepatic stellate cells were cultivated and subsequently stimulated with LPS. Histone H3K9 methylation and associated methyltransferase levels were quantified. G9a function was investigated by the G9a methyltransferase inhibitor UNC0642.

resultsIn rats and mice with pulpitis, BMP9 expression initially declined in both the liver and blood, followed by a subsequent increase. This BMP9 trend in LPS-stimulated hepatic stellate cells mirrored the findings observed in vivo. Mechanistically, the involvement of H3K9 dimethylation and G9a methyltransferase in this process was elucidated. Treatment with UNC0642 successfully restored suppressed BMP9 levels. Chromatin immunoprecipitation assays further confirmed an increased enrichment of H3K9 dimethylation in the promoter region of the BMP9 gene following LPS stimulation of mouse hepatic stellate cells.

conclusionThese findings suggested that LPS in pulpitis might transiently influence the expression of BMP9 in liver tissues, and pulpitis might have potential effects on systemic tissues and organs. CLINICAL RELEVANCE: This study provides a proof-of-concept for targeting epigenetic pathways to mitigate the oral-systemic disease link, motivating future clinical trials in high-risk populations.
