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

backgroundAbnormal innate immune response contributes to inflammatory bowel disease (IBD) and experimental mouse colitis. Colitis studies have focused primarily on key regulators of innate immunity, like pathogen recognition receptors and cytoplasmic mediators. Extracellular matrix (ECM) proteins are emerging as modulators of inflammatory responses by virtue of their interactions with pathogen-associated molecular patterns (PAMPs), cytokines, growth factors, receptors, and ECM fragments that mimic pathogens or cytokines. The ECM proteins have not been investigated in IBD at great depth from this standpoint. We have shown previously that the ECM protein lumican modulates host sensing of bacterial lipopolysaccharides (LPS) by Toll-like receptor (TLR) 4, and neutrophil chemotaxis via integrins.

methodsHere we investigated the role of lumican in the development of colitis mediated by intrarectal administration of the hapten 2-4-5, trinitrobenzene sulfonic acid (TNBS) in Lum(+/+) and Lum(-/-) mice.

resultsThe TNBS treated Lum(+/+) mouse colons showed marked increases in CXCL1, tumor necrosis factor alpha (TNF-α), and neutrophil infiltration, whereas these responses were significantly dampened in the Lum(-/-) mice. The nuclear factor kappa B (NF-κB) transcription factor, known to regulate inflammatory genes, showed a robust increase after TNBS treatment in Lum(+/+) but not in Lum(-/-) colons. Also, nuclear translocation of NF-κB was delayed in LPS stimulated Lum(-/-) primary peritoneal macrophages.

conclusionsThe Lum(-/-) mice have low innate immune and inflammatory responses, but more severe body weight loss and tissue damage, a phenomenon seen in the innate immune impaired Tlr4(-/-) and MyD88(-/-) mice. Therefore, lumican promotes intestinal homeostasis by aiding innate immune and inflammatory responses that are beneficial in the early stages of colitis.
