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

objectivePeroxisome proliferator-activated receptor α (PPARα) activation has been reported to ameliorate liver injury in cases of acute liver failure (ALF). However, its intrinsic protective molecular mechanisms remain largely undetermined. C/EBP homologous protein (CHOP) is an important mediator of lipopolysaccharide (LPS)-induced inflammation. The aim of the present study was to test the hypothesis that PPARα activation alleviates liver inflammation to protect mice from acute liver failure (ALF) mediated by CHOP.

methodsIn a murine model induced by D-galactosamine (D-GalN, 700 mg/kg) and LPS (10 μg/kg), Wy-14643 (6 mg/kg) was administered to activate PPARα. The mice of different groups were killed 6 h after D-GalN/LPS injection, and the liver and blood were collected for analysis. To find out whether PPARα activation protects the liver from injury due to inflammation by regulating CHOP, we used expression plasmid to increase CHOP expression and demonstrated how PPARα mediated CHOP to regulate inflammation in vivo and in vitro.

resultsThe expression of PPARα was downregulated and the expression of CHOP was upregulated with the development of D-GalN/LPS-induced liver injury. The protective molecular mechanisms of PPARα activation were dependent on the expression of CHOP. Indeed, (1) PPARα activation decreased the expression of CHOP; on the other hand, PPARα knockdown increased the expression of CHOP in vivo; (2) the depressed liver inflammation by PPARα activation was due to the downregulation of CHOP expression, because overexpression of CHOP by transfect plasmid reversed liver protection and increased liver inflammation again; (3) in vitro, PPARα inhibition by siRNA treatment increased the expression of proinflammatory cytokines, and CHOP siRNA co-transfection reversed the expression of proinflammatory cytokines.

conclusionsHere, we demonstrated that PPARα activation contributes to liver protection and decreases liver inflammation in ALF, particularly through regulating CHOP. Our findings may provide a rationale for targeting PPARα as a potential therapeutic strategy to ameliorate ALF.
