Bone morphogenetic protein 10 is increased in pre-capillary pulmonary hypertension patients.

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
aimsPre-capillary pulmonary hypertension (precPH) results in increased right atrial (RA) stretch and pressure. The right atrium is the major source of bone morphogenetic protein 10 (BMP10) in adults, primarily produced by RA cardiomyocytes. The aim of this study was to investigate BMP10 expression in the right heart and systemic circulation and to identify potential triggers for increased BMP10 secretion associated with precPH. METHODS AND
resultsWe examined BMP10 mRNA and protein expressions in RA tissue. Circulating BMP10 plasma levels were determined using enzyme-linked immunosorbent assay. BMP10 transcriptional activity was studied using a BMP-responsive element luciferase assay. Correlation analyses were performed between circulating BMP10 and RA dilatation as well as right ventricular (RV) function. Finally, we determined the impact of pressure unloading on BMP10 activity in chronic thromboembolic pulmonary hypertension (CTEPH) patients before and after pulmonary endarterectomy (PEA). BMP10 mRNA's protein and activity were significantly increased in the precPH right atrium. While circulating BMP10 protein levels were elevated, no significant changes were observed in BMP10 transcriptional activity between precPH and controls. Interestingly, RA dilatation, increased RA pressure, high N-terminal pro b-type natriuretic peptide levels, and reduced RV ejection fraction were associated with high BMP10 activity. Finally, pressure unloading after PEA in a cohort of CTEPH patients resulted in reduced BMP10 activity.
conclusionRA BMP10 expression and plasma levels are increased in precPH, likely triggered by excessive RA dilatation and pressure overload. Future studies are needed to determine whether increased BMP10 release is an adaptive mechanism or a potential therapeutic target.
