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

backgroundAlthough the contractile, migratory, and proliferative responses of subepithelial myofibroblasts to injury have been postulated to be important events in intestinal wound healing, contractile force generation and migration by these cells has not been investigated previously, and the signals that regulate proliferation by these cells are poorly understood.

aimsThe primary aim of this study was to test the hypothesis that the inflammatory mediator endothelin-1 modulates contraction, migration, and proliferation of intestinal myofibroblasts. We also sought to examine the signal transduction pathways which might underlie these putative effects.

methodsContraction, migration, proliferation, cytosolic [Ca(2+)], and myosin phosphorylation were measured in human colonic subepithelial myofibroblasts in the absence and presence of endothelin receptor agonists and antagonists.

resultsEndothelin-1, but not interleukin 1 alpha, interleukin 6, interleukin 8, interleukin 10, or tumour necrosis factor alpha, induced a rapid and robust generation of contractile force, which was associated with an increase in cytosolic [Ca(2+)] and myosin phosphorylation. Inhibition of rho associated kinase reduced endothelin-1 stimulated myosin phosphorylation and contractile force development. Endothelin-1 stimulated migration with a dose-response relationship similar to that observed for contraction. Endothelin A and B receptors mediated contraction while migration was mediated predominantly through endothelin B receptors. Platelet derived growth factor and serum, but not endothelin-1, induced proliferation.

conclusionsEndothelin-1 stimulates colonic subepithelial myofibroblast contraction and migration via endothelin receptor mediated myosin phosphorylation. These results support an important role for subepithelial myofibroblasts in the injury response of the gut and consequently intestinal wound repair.
