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

backgroundNesfatin/Nucleobindin-2 (Nesf/NUCB2), a precursor of nesfatin-1, an anorexigenic protein, is ubiquitously expressed in peripheral tissues in addition to the hypothalamus. However, the role of intracellular Nesf/NUCB2 has not been established in the periphery.

methodsNesf/NUCB2-transgenic (Tg) mice were generated, and chronological changes of body weight and daily food intake were measured in Nesf/NUCB2-Tg mice fed normal laboratory chow or 45% high-fat diet (HFD). In addition, changes of metabolic markers were evaluated in those mice.

resultsNo differences were observed in daily food intake and body weight between Nesf/NUCB2-Tg mice (n=11) and their non-Tg littermates (n=11) fed normal chow. Nesf/NUCB2-Tg mice showed increased mRNA expression of oxytocin and corticotropin-releasing hormone and decreased mRNA expression of cocaine- and amphetamine-related transcript in the hypothalamus. Nesf/NUCB2-Tg mice fed 45% HFD (n=6) showed significantly higher increase in body weight than their non-Tg littermates fed the same diet (n=8); however, no difference was observed in daily food intake between these two groups. Further, Nesf/NUCB2-Tg mice fed 45% HFD showed a significant increase in the weight of the liver, subcutaneous fat, and brown adipose tissue and decrease in the expression of uncoupling protein-1 in the subcutaneous fat. Blood glucose levels of Nesf/NUCB2-Tg mice fed 45% HFD were not different from those of their non-Tg littermates fed the same diet. Insulin levels of these Tg mice were significantly higher than those of their non-Tg littermates. Histological analysis showed marked fat deposition in the hepatocytes surrounding the hepatic central veins in Nesf/NUCB2-Tg mice fed 45% HFD.

conclusionsOverexpression of Nesf/NUCB2 did not change food intake, but increased body weight only in Nesf/NUCB2-Tg mice fed HFD. The results of this study indicate that Nesf/NUCB2 was involved in the development of insulin resistance and fat deposition in the liver, independent of the modulation of energy intake.
