Tamoxifen and ATP synergistically activate Cl- release by cultured bovine pigmented ciliary epithelial cells.
Article in The Journal of physiology, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Purines alter aqueous humour secretion by the bilayered ciliary epithelium. Adenosine but not ATP shrinks non-pigmented ciliary epithelial (NPE) cells by activating Cl- channels. We now report effects of ATP on pigmented ciliary epithelial (PE) cells. Cultured bovine PE cells were studied volumetrically by electronic cell sorting. ATP and tamoxifen acted synergistically to shrink PE cells. Neither ATP nor tamoxifen alone had a consistent effect on cell volume. The tamoxifen, ATP-activated shrinkage required Cl- release since the response was blocked by removing Cl- and was inhibited by the Cl- channel blockers 5-nitro-2-(3-phenylpropylamino)-benzoate and 4,4'-diisothiocyano-2,2'-disulfonic acid. The modulating effect of tamoxifen could have reflected many actions of tamoxifen. Our data do not support the suggestion that tamoxifen inhibits protein kinase C (PKC) or calcium-calmodulin, or that it acts on histamine or carbachol receptors. The shrinkage produced by ATP and tamoxifen was blocked by 17beta-oestradiol, but not 17alpha-oestradiol. The cooperative interaction between tamoxifen and ATP was not mediated by an enhanced rise in [Ca2+]i. The results indicate that tamoxifen interacts synergistically with ATP to activate Cl- release by the PE cells.
