P2Y receptor-mediated Ca2+ signalling in cultured rat aortic smooth muscle cells.
Article in British journal of pharmacology, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
1. ATP, UTP, ADP and ADP-beta-S elicited Ca2+ -signals in cultured aortic smooth muscle cells although ADP, UDP and ADP-beta-S gave approximately 40% of the maximal response seen with ATP and UTP. Adenosine, AMP or alpha,beta-methylene-ATP had no effect. These responses were attributed to P2Y2/4 and P2Y1 receptors, which we assumed could be selectively activated by UTP and ADP-beta-S respectively. 2. The response to UTP was reduced (approximately 50%) by pertussis toxin, whilst this toxin had no effect upon the response to ADP-beta-S. This suggests P2Y2/4 receptors simultaneously couple to pertussis toxin-sensitive and -resistant G proteins whilst P2Y1 receptors couple to only the toxin-resistant proteins. 3. Repeated stimulation with UTP or ADP-beta-S caused desensitization which was potentiated by 12-O-tetradecanoyl phorbol-13-acetate (TPA) and attenuated by staurosporine. 4. TPA completely abolished sensitivity to ADP-beta-S but the response to UTP had a TPA-resistant component. In pertussis toxin-treated cells, however, TPA could completely abolish sensitivity to UTP and so the TPA-resistant part of this response seems to be mediated by pertussis toxin-sensitive G proteins. 5. Loss of sensitivity to UTP did not occur when pertussis toxin-treated cells were repeatedly stimulated with this nucleotide, suggesting that pertussis toxin-sensitive G proteins mediate this effect. The toxin did not, however affect desensitization to ADP-beta-S.
