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

BACKGROUND AND

aimsLittle is known about the intestinal epithelial expression and secretion of CXCL10 (IP-10), a chemokine involved in recruiting T cells and monocytes. We aimed to study CXCL10 gene expression and regulation by the pro-inflammatory cytokines interleukin (IL)-1beta, interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha in intestinal epithelial cell lines. MATERIALS AND

methodsCXCL10 expression and secretion kinetics were assessed in Caco-2, HT-29 and DLD1 human colon epithelial cells, treated with IL-1beta, TNF-alpha, IFN-gamma alone or in combination with each other by real-time polymerase chain reaction (PCR), Northern blotting and enzyme-linked immunoabsorbent assay (ELISA). Transient transfections with TGL-IP10 (CXCL10 promoter) and TGL-IP10-kappaB2 mutant promoter and gelshifts and supershifts for nuclear factor (NF)-kappaB were also performed.

resultsReal-time PCRs and ELISA experiments revealed that IL-1beta was the strongest and earliest inducer of CXCL10 messenger ribonucleic acid (mRNA) expression and protein secretion in Caco-2 cell line, whereas INF-gamma had a delayed kinetics. There was a strong synergistic effect of either TNF-alpha or IL-1beta with IFN-gamma both on CXCL10 mRNA expression and protein secretion in all three cell lines. Real-time PCR and ELISA experiments using a specific NF-kappaB inhibitor and transfection experiments with a NF-kappaB-binding defective CXCL10 promoter construct revealed that the induction of CXCL10 by IL-1beta and its synergism with IFN-gamma is NF-kappaB dependent.

conclusionThese data demonstrate that in colonic epithelial cells, depending on the cellular context and utilizing the NF-kappaB pathway, IL-1beta alone and/or in synergism with IFN-gamma may play a major role in the induction of CXCL10.
