Functional expression of the interleukin-11 receptor alpha-chain in normal colonic epithelium and colon cancer.

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
backgroundInterleukin-11 (IL-11) has been evaluated as an anti-inflammatory and mucosa-protective therapeutic agent in inflammatory bowel diseases (IBDs). Activity of IL-11 requires binding to the alpha receptor subunit (IL-11Ralpha) that provides ligand specificity. Recently, we showed that in the intestinal mucosa, IL-11Ralpha is mainly present on epithelial cells mediating antiapoptotic effects. The aim of this study was to investigate the expression profiling of IL-11Ralpha and its downstream signaling cascade in colonic adenoma and carcinoma. MATERIALS AND
methodsThe expression of IL-11Ralpha in normal colonic mucosa, 11 colonic adenomas, and 10 carcinomas was analyzed by immunohistochemistry. In addition, IL-11Ralpha-expression and IL-11Ralpha-induced phosphorylation of signal transducer and activator of transcription (STAT)3 were investigated by Western blot analysis.
resultsImmunohistochemistry revealed significant IL-11-Ralpha expression in epithelial cells of normal colonic mucosa. In contrast, the expression of IL-11-Ralpha in colon adenomas and carcinomas was either absent or only detectable in very few scattered epithelial cells. Densitometric analysis of Western blots confirmed these results, showing a decrease of IL-11Ralpha-protein in cells isolated from adenomas or carcinomas. Reduced STAT3-phosphorylation in carcinoma cells indicated functional consequences of decreased IL-11Ralpha-protein expression on signal transduction.
conclusionThis study demonstrates a decrease of IL-11-Ralpha-protein expression in epithelial cells isolated from colon carcinomas and adenomas compared to normal colonic mucosa and a reduced STAT3 signaling. Because of reduced binding and signal transduction, it is unlikely that therapeutically administered IL-11 would contribute to colorectal carcinoma induction and growth.
