Tumour necrosis factor alpha potentiates ion secretion induced by histamine in a human intestinal epithelial cell line and in mouse colon: involvement of the phospholipase D pathway.
Article in Gut, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND AND
aimsPatients suffering from inflammatory bowel disease show increased levels of the mast cell products histamine and tumour necrosis factor alpha (TNF-alpha). Treating these patients with antibodies against TNF-alpha diminishes the symptoms of diarrhoea. In this study, the effect of TNF-alpha on ion secretion induced by the mast cell mediator histamine in HT29cl.19A cells and mouse distal colon was investigated and the possible second messengers involved were studied.
methodsElectrophysiology of filter grown HT29cl.19A cells and isolated mouse distal colon was used to monitor the secretory response to histamine with and without prior exposure to TNF-alpha for 3-24 hours. Phospholipase D (PLD) activity and phosphatidic acid levels were analysed by 32P(i) labelling of HT29cl.19A cells.
resultsIn both experimental systems TNF-alpha was found to potentiate ion secretion induced by histamine. Phospholipid analysis of HT29cl.19A cells revealed that histamine activates the PLD pathway. Furthermore, TNF-alpha pretreated cells were found to have decreased phosphatidic acid levels, the intermediate product of the PLD pathway, which indicates upregulation of the enzyme phosphatidic acid phosphatase.
conclusionsThe mast cell products TNF-alpha and histamine synergistically stimulate ion secretion in intestinal epithelium via upregulation of the PLD pathway.
