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

Agonists of the sphingosine-1-phosphate receptor (S1PR) attenuate kidney ischemia-reperfusion injury (IRI). Previous studies suggested that S1P1R-induced lymphopenia mediates this protective effect, but lymphocyte-independent mechanisms could also contribute. Here, we investigated the effects of S1PR agonists on kidney IRI in mice that lack T and B lymphocytes (Rag-1 knockout mice). Administration of the nonselective S1PR agonist FTY720 or the selective S1P1R agonist SEW2871 reduced injury in both Rag-1 knockout and wild-type mice. In vitro, SEW2871 significantly attenuated LPS- or hypoxia/reoxygenation-induced apoptosis in cultured mouse proximal tubule epithelial cells, supporting a direct protective effect of S1P1R agonists via mitogen-activated protein kinase and/or Akt pathways. S1P1Rs in the proximal tubule mediated IRI in vivo as well: Mice deficient in proximal tubule S1P1Rs experienced a greater decline in renal function after IRI than control mice and their kidneys were no longer protected by SEW2871 administration. In summary, S1PRs in the proximal tubule are necessary for stress-induced cell survival, and S1P1R agonists are renoprotective via direct effects on the tubule cells. Selective agonists of S1P1Rs may hold therapeutic potential for the prevention and treatment of acute kidney injury.
