Specific detection of OCT4 isoforms in inflammatory bowel disease.
Article in Gut pathogens, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundDevelopmentally early cells are mobilized into peripheral blood in Crohn's disease (CD) patients. OCT4, is considered to be important in sustaining the pluripotency of stem cells. OCT4 splicing variants are differentially expressed in pluripotent and non-pluripotent cells. Our study aims to investigate the expression pattern of OCT4 variants and SOX-2, an essential factor implicated in self-renewal and pluripotency, in tissue and blood samples from patients with IBD.
methodsPeripheral blood and tissue samples were collected from patients with active CD and ulcerative colitis (UC), and from healthy individuals. OCT4 expression was documented by Western blot, immunohistochemistry and by reverse transcription-real-time PCR. OCT4 isoform determination was documented using specific primers. SOX-2 expression levels were also evaluated.
resultsOCT4 protein levels were significantly higher in CD tissue samples than in CD blood samples, and in UC tissue samples. OCT4 protein was localized mainly in the cytosol. In all samples, only the OCT4 pseudogenes and the OCT4B1 variant were detected. OCT4B1 expression levels were elevated in both tissue and blood samples from CD and UC cases compared to healthy controls. In CD patients only SOX-2 mRNA levels were found slightly increased compared to healthy controls.
conclusionOur results suggest that OCT4 is expressed in patients with IBD. Furthermore, we found the presence of the OCT4B1 isoform in IBD in both tissue and blood samples. Our results have shown, that developmentally early cells might be mobilized into peripheral blood as result of tissue damage, indicating a possible role of these cells in repair of injured intestinal tract.
