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/hypothesisAccumulating evidence has revealed the significant role of glucagon-like peptide-1 (GLP-1) in weight loss. Sirtuin 1 (SIRT1) plays a vital role in the regulation of lipid metabolism. Here, we investigated the contribution of lipolytic and oxidative changes in white adipose tissue (WAT) to the weight-lowering effect induced by the GLP-1 receptor (GLP-1R) agonist exenatide (exendin-4) in mice. We also looked at the role of SIRT1 in this process.

methodsC57BL/6J mice and Sirt1 (+/-) mice were treated with exenatide (24 nmol/kg) or an NaCl solution (154 mmol/l) control i.p. for 8 weeks while receiving a high-fat diet (HFD) after a 12 week HFD challenge. Systemic phenotypic evaluations were carried out during and after the intervention. A lentivirus-mediated short hairpin (sh)RNA vector of the Sirt1 gene was transfected into differentiated 3T3-L1 adipocytes. An in vitro model system used adipocytes induced from Sirt1-null mouse embryonic fibroblasts (MEFs).

resultsExenatide reduced fat mass and enhanced the lipolytic and oxidative capacity of WAT in diet-induced obese C57BL/6J mice. However, these effects were significantly impaired in Sirt1 (+/-) mice compared with wild-type controls. In vitro, exendin-4 increased lipolysis and fatty acid oxidation by upregulating SIRT1 expression and activity in differentiated 3T3-L1 adipocytes. Conversely, RNA interference (i)-induced knockdown of SIRT1 attenuated the lipolytic and oxidative responses to exendin-4 in differentiated 3T3-L1 adipocytes. Again, these responses were entirely abolished in Sirt1-null MEFs after induction into adipocytes. CONCLUSIONS/

interpretationThese data highlight that a GLP-1R agonist promotes brown remodelling of WAT in a SIRT1-dependent manner; this might be one of the mechanisms underlying its effect on weight loss.
