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

backgroundWhile others have described gene expression patterns in humans with inflammatory bowel diseases and animals with chemically induced colitis, a genome-wide comparison of gene expression in genetically susceptible animals that develop spontaneous colitis has not been reported.

methodsWe used microarray technology to compare gene expression profiles in cecal specimens from specific pathogen-free IL10-deficient (IL10-/-) mice with colitis and normal wildtype (WT) mice. RNA isolated from ceca of IL10-/- and WT mice was subjected to microarray analysis. The results were confirmed by real-time polymerase chain reaction (PCR) and immunofluorescence microscopy of selected molecules. Expression of the selected genes in dextran sodium sulfate (DSS)-treated mice with colitis and epithelial cell lines activated with pathophysiologic stimuli was measured by real-time PCR.

resultsHistological inflammation of the colon and IL-12/23p40 secretion from intestinal explants were greater in IL10-/- and DSS-treated mice versus WT and untreated mice. Microarray analysis demonstrated >10-fold induction of the following molecules in the ceca of IL10-/- mice: mitochondrial ribosomal protein-L33, aquaporin-4, indoleamine-pyrrole-2,3-dioxygenase, and MHC class II with 63, 25, 20, and 12-fold increases, respectively. Cytochrome-P450, pancreatic lipase-related protein-2, and transthyretin were downregulated in IL10-/- mice. MHC II was increased throughout the colon, and aquaporin-4 was increased in the basolateral aspect of cecal epithelial cells. MHC II mRNA was increased in epithelial cells treated with IFN-gamma, but not TNF or Toll-like receptor ligands.

conclusionsAlthough most upregulated genes in experimental colitis are immune-related, aquaporin-4 and mitochondrial ribosomal protein-L33, which have not been previously associated with inflammation, were most highly upregulated.
