Control of epithelial ion transport by Cl- and PDZ proteins.
Article in The Journal of membrane biology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Inhibition of epithelial Na+ channels (ENaC) by the cystic fibrosis transmembrane conductance regulator (CFTR) has been demonstrated previously. Recent studies suggested a role of cytosolic Cl- for the interaction of CFTR with ENaC, when studied in Xenopus oocytes. In the present study we demonstrate that the Na+ / H+ -exchanger regulator factor (NHERF) controls expression of CFTR in mouse collecting duct cells. Inhibition of NHERF largely attenuates CFTR expression, which is paralleled by enhanced Ca(2+) -dependent Cl- secretion and augmented Na+ absorption by the ENaC. It is further demonstrated that epithelial Na+ absorption and ENaC are inhibited by cytosolic Cl- and that stimulation by secretagogues enhances the intracellular Cl- concentration. Thus, the data provide a clue to the question, how epithelial cells can operate as both absorptive and secretory units: Increase in intracellular Cl- during activation of secretion will inhibit ENaC and switch epithelial transport from salt absorption to Cl- secretion.
