Pigment Epithelium-Derived Factor Induces Endothelial Barrier Dysfunction via p38/MAPK Phosphorylation.
Article in BioMed research international, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Endothelial barrier dysfunction, which is a serious problem that occurs in various inflammatory conditions, permits extravasation of serum components into the surrounding tissues, leading to edema formation and organ failure. Pigment epithelium-derived factor (PEDF), which is a major endogenous antagonist, has been implicated in diverse biological process, but its role in endothelial barrier dysfunction has not been defined. To assess the role of PEDF in the vasculature, we evaluated the effects of exogenous PEDF using human umbilical vein endothelial cells (HUVECs) in vitro. Our results demonstrated that exogenous PEDF activated p38/MAPK signalling pathway in a dose- and time-dependent manner and induced vascular hyperpermeability as measured by the markedly increased FITC-dextran leakage and the decreased transendothelial electrical resistance (TER) across the monolayer cells, which was accompanied by microtubules (MTs) disassembly and F-actin rearrangement. However, the aforementioned alterations can be arrested by the application of low concentration of p38/MAPK inhibitor SB203580. These results reveal a novel role for PEDF as a potential vasoactive substance in inducing hyperpermeability. Furthermore, our results suggest that PEDF and p38/MAPK may serve as therapeutic targets for maintaining vascular integrity.
