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

aims/hypothesisExcessive ectopic lipid deposition contributes to impaired insulin action in peripheral tissues and is considered an important link between obesity and type 2 diabetes mellitus. Acetyl-CoA carboxylase 2 (ACC2) is a key regulatory enzyme controlling skeletal muscle mitochondrial fatty acid oxidation; inhibition of ACC2 results in enhanced oxidation of lipids. Several mouse models lacking functional ACC2 have been reported in the literature. However, the phenotypes of the different models are inconclusive with respect to glucose homeostasis and protection from diet-induced obesity.

methodsHere, we studied the effects of pharmacological inhibition of ACC2 using as a selective inhibitor the S enantiomer of compound 9c ([S]-9c). Selectivity was confirmed in biochemical assays using purified human ACC1 and ACC2.

results(S)-9c significantly increased fatty acid oxidation in isolated extensor digitorum longus muscle from different mouse models (EC(50) 226 nmol/l). Accordingly, short-term treatment of mice with (S)-9c decreased malonyl-CoA levels in skeletal muscle and concomitantly reduced intramyocellular lipid levels. Treatment of db/db mice for 70 days with (S)-9c (10 and 30 mg/kg, by oral gavage) resulted in improved oral glucose tolerance (AUC -36%, p < 0.05), enhanced skeletal muscle 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) uptake, as well as lowered prandial glucose (-31%, p < 0.01) and HbA(1c) (-0.7%, p < 0.05). Body weight, liver triacylglycerol, plasma insulin and pancreatic insulin content were unaffected by the treatment. CONCLUSIONS/

interpretationIn conclusion, the ACC2-selective inhibitor (S)-9c revealed glucose-lowering effects in a mouse model of diabetes mellitus.
