Ibuprofen inhibits cystic fibrosis transmembrane conductance regulator-mediated Cl- secretion.

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
We evaluated the acute effects of ibuprofen and salicylic acid on cAMP-mediated Cl- secretion (Isc) in both colonic and airway epithelia. In T84 cells, ibuprofen inhibited the forskolin-dependent Isc in a concentration-dependent manner, having an apparent Ki of 142 microM. Salicylic acid inhibited Isc with an apparent Ki of 646 microM. We determined whether ibuprofen would also inhibit the forskolin-stimulated Isc in primary cultures of mouse trachea epithelia (MTE) and human bronchial epithelia (HBE). Similar to our results in T84 cells, ibuprofen (500 microM) inhibited the forskolin-induced Isc in MTEs and HBEs by 59+/-4% (n = 11) and 39+/-6% (n = 8), respectively. Nystatin was employed to selectively permeabilize the basolateral or apical membrane to determine the effect of ibuprofen on apical Cl- (ICl) and basolateral K+ (IK) currents after stimulation by forskolin. After forskolin stimulation, ibuprofen (500 microM) reduced both the ICl and IK; reducing ICl and IK by 60 and 15%, respectively. To determine whether this inhibition of ICl was due to the inhibition of CFTR, the effects of ibuprofen and salicylic acid on CFTR Cl- channels in excised, inside-out patches from L-cells were evaluated. Ibuprofen (300 microM) reduced CFTR Cl- current by 60+/-16% and this was explained by a short-lived block (approximately 1.2 ms) which causes an apparent reduction in single channel amplitude from 1.07+/-0.04 pA to 0.59+/-0.04 pA (n = 3). Similarly, salicylic acid (3 mM) reduced CFTR Cl- current by 50+/-8% with an apparent reduction in single channel amplitude from 1.08+/-0.03 pA to 0.48+/-0.06 pA (n = 4). Based on these results, we conclude that the NSAIDs ibuprofen and salicylic acid inhibit cAMP-mediated Cl- secretion in human colonic and airway epithelia via a direct inhibition of CFTR Cl- channels as well as basolateral membrane K+ channels. This may reduce their efficacy in conjunction with other therapeutic strategies designed to increase CFTR expression and/or function in secretory epithelia.
