Sphingosine 1-phosphate receptor 1 governs endothelial barrier function and angiogenesis by upregulating endoglin signaling.

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
Background: The sphingosine 1-phosphate (S1P)/S1P receptor (S1pr) 1 signaling plays an essential role in regulating vascular integrity and angiogenesis. We have previously shown that cell-surface expression of endoglin (Eng) is sustained by S1P/S1pr1 signaling in endothelial cells (ECs). However, whether S1pr1 mediates Eng signaling, or vice versa, remains unknown. Methods: S1pr1 inhibitors were used to study whether pharmacological inhibition induces basal vascular leakage Results: The present study elucidated that S1pr1 and Eng are both pivotal for angiogenesis in the postnatal mouse retina, and that the activation of S1pr1 or Eng increases vascular barrier function. Activation of S1pr1 enhanced the phosphorylation of Smad family members 1, 5, and 8 (pSmad1/5/8), while the inhibition of S1pr1 reduced the levels of pSma1/5/8 induced by BMP9 treatment. Activation or loss of Eng did not affect S1pr1 signaling. Moreover, activation of ERK was involved in promoting EC-surface expression of Eng by S1pr1. Conclusions: Our data demonstrates for the first time that there exists a linear pathway of S1pr1-Eng signaling axis in ECs, which governs vascular homeostasis. Functional BMP9/Eng signaling requires S1P/S1pr1 activation, and S1pr1 signaling acts as a vascular protection mechanism upstream of Eng.
