The lncRNA SENCR knockdown alleviates vascular calcification via miR-4731-5p by suppressing endoplasmic reticulum stress.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAccumulation of calcium phosphate crystals is associated with vascular calcification (VC); however, the mechanism that promotes VC remains unclear. Accumulating evidence indicates that smooth muscle and endothelial cell-enriched migration/differentiation-associated lncRNA (SENCR) exerts a critical role in VC. This work focuses on the molecules involved in β-glycerophosphate-induced osteogenic differentiation of vascular smooth muscle cells (VSMCs) through SENCR epigenetic modification of Runx2 in an endoplasmic reticulum stress (ERS)-dependent manner.
methodsWe cultured VSMCs to explore the relationship among β-glycerophosphate, SENCR, and VC and also investigate the function of SENCR in β-glycerophosphate-induced osteogenic differentiation and VC in vitro.
resultsOur findings indicate that β-glycerophosphate enhanced SENCR, MSH homeobox 2, Runx2, ERS-related markers, alkaline phosphatase activity, and cellular calcium deposition and suppressed the expression of α-SMA, SM 22α, and miR-4731-5p. SENCR silencing increased miR-4731-5p expression, which subsequently inhibited β-glycerophosphate-associated endoplasmic reticulum stress at the post-transcriptional level. Critically, the facts that direct interplay between SENCR and miR-4731-5p, and the downregulation of miR-4731-5p efficiently reversed the suppression of ERS-induced by SENCR silencing were observed. Collectively, the present study clarifies a novel mechanism by which downregulation of SRNRC contributes to the ERS-dependent osteogenic differentiation of VSMCs and VC by sponging miR-4731-5p. This study demonstrates that SENCR/miR-4731-5p axis is involved in β-glycerophosphate-mediated VC in vitro.
