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

Impaired angiogenesis in scleroderma (SSc) is a critical component of SSc pathology. MicroRNA-126 (miR-126) is expressed in endothelial cells (MVECs) where it regulates VEGF responses by repressing the negative regulators of VEGF, including the sprouty-related protein-1 (SPRED1), and phosphoinositide-3 kinase regulatory subunit 2 (PIK3R2). MVECs were isolated from SSc skin and matched subjects (n = 6). MiR-126 expression was measured by qPCR and in situ hybridization. Matrigel-based tube assembly was used to test angiogenesis. MiR-126 expression was inhibited by hsa-miR-126 inhibitor and enhanced by hsa-miR-126 Mimic. Epigenetic regulation of miR-126 expression was examined by the addition of epigenetic inhibitors (Aza and TSA) to MVECs and by bisulphite genomic sequencing of DNA methylation of the miR-126 promoter region. MiR-126 expression, as well as EGFL7 (miR-126 host gene), in SSc-MVECs and skin, was significantly down-regulated in association with increased expression of SPRED1 and PIK3R2 and diminished response to VEGF. Inhibition of miR-126 in NL-MVECs resulted in reduced angiogenic capacity, whereas overexpression of miR-126 in SSc-MVECs resulted in enhanced tube assembly. Addition of Aza and TSA normalized miR-126 and EGFL7 expression levels in SSc-MVECs. Heavy methylation in miR-126/EGFL7 gene was noted. In conclusion, these results demonstrate that the down-regulation of miR-126 results in impaired VEGF responses.
