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

Multiple Ca(2+) release and entry mechanisms and potential cytoskeletal targets have been implicated in vascular endothelial barrier dysfunction; however, the immediate downstream effectors of Ca(2+) signals in the regulation of endothelial permeability still remain unclear. In the present study, we evaluated the contribution of multifunctional Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) as a mediator of thrombin-stimulated increases in human umbilical vein endothelial cell (HUVEC) monolayer permeability. For the first time, we identified the CaMKIIdelta(6) isoform as the predominant CaMKII isoform expressed in endothelium. As little as 2.5 nM thrombin maximally increased CaMKIIdelta(6) activation assessed by Thr(287) autophosphorylation. Electroporation of siRNA targeting endogenous CaMKIIdelta (siCaMKIIdelta) suppressed expression of the kinase by >80% and significantly inhibited 2.5 nM thrombin-induced increases in monolayer permeability assessed by electrical cell-substrate impedance sensing (ECIS). siCaMKIIdelta inhibited 2.5 nM thrombin-induced activation of RhoA, but had no effect on thrombin-induced ERK1/2 activation. Although Rho kinase inhibition strongly suppressed thrombin-induced HUVEC hyperpermeability, inhibiting ERK1/2 activation had no effect. In contrast to previous reports, these results indicate that thrombin-induced ERK1/2 activation in endothelial cells is not mediated by CaMKII and is not involved in endothelial barrier hyperpermeability. Instead, CaMKIIdelta(6) mediates thrombin-induced HUVEC barrier dysfunction through RhoA/Rho kinase as downstream intermediates. Moreover, the relative contribution of the CaMKIIdelta(6)/RhoA pathway(s) diminished with increasing thrombin stimulation, indicating recruitment of alternative signaling pathways mediating endothelial barrier dysfunction, dependent upon thrombin concentration.
