The induction of lipocalin-2 protein expression in vivo and in vitro.
Article in The Journal of biological chemistry, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 58 papers.
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.
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
Lipocalin-2 (LCN2) is secreted from adipocytes, and its expression is up-regulated in obese and diabetic mice and humans. LCN2 expression and secretion have been shown to be induced by two proinflammatory cytokines, IFNγ and TNFα, in cultured murine and human adipocytes. In these studies, we demonstrated that IFNγ and TNFα induced LCN2 expression and secretion in vivo. Although we observed a strong induction of LCN2 expression and secretion from white adipose tissue (WAT) depots, the induction of LCN2 varied among different insulin-sensitive tissues. Knockdown experiments also demonstrated that STAT1 is required for IFNγ-induced lipocalin-2 expression in murine adipocytes. Similarly, knockdown of p65 in adipocytes demonstrated the necessity of the NF-κB signaling pathway for TNFα-mediated effects on LCN2. Activation of ERKs by IFNγ and TNFα also affected STAT1 and NF-κB signaling through modulation of serine phosphorylation. ERK activation-induced serine phosphorylation of both STAT1 and p65 mediated the additive effects of IFNγ and TNFα on LCN2 expression. Our results suggest that these same mechanisms occur in humans as we observed STAT1 and NF-κB binding to the human LCN2 promoter in chromatin immunoprecipitation assays performed in human fat cells. These studies substantially increase our knowledge regarding the requirements and mechanisms used by proinflammatory cytokines to induce LCN2 expression.
