Oxidized ATP (oATP) attenuates proinflammatory signaling via P2 receptor-independent mechanisms.
Article in British journal of pharmacology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 65 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
Periodate-oxidized ATP (oATP), which covalently modifies nucleotide-binding proteins, can significantly attenuate proinflammatory signaling. Although the P2X7 nucleotide receptor (P2X7R) is irreversibly antagonized by oATP, it is unclear whether anti-inflammatory actions of oATP are predominantly mediated via its actions on P2X7R. Here, we describe inhibitory effects of oATP on proinflammatory responses in three human cell types that lack expression of P2X7R: human umbilical vein endothelial cells (HUVEC), HEK293 cells, and 1321N1 astrocytes. oATP decreased by 40-70% the secretion of interleukin (IL)-8 stimulated by tumor necrosis factor-alpha (TNF-alpha) in all three cell types, by IL-1beta in HUVEC and 1321N1 cells, and by endotoxin in HUVEC. Attenuation of TNF-alpha-stimulated IL-8 secretion by oATP was similar in wild-type HEK cells or HEK cells stably expressing recombinant P2X7R. oATP also attenuated cytokine-stimulated expression of nuclear factor-kappaB-luciferase reporter genes expressed in HEK or 1321N1 cells, but did not affect the rapid downregulation of IkappaB. oATP had no effect on uridine triphosphate-induced activation of native P2Y2 receptors in HEK cells, but reduced the potency and efficacy of ADP as an agonist of native P2Y1 receptors. However, inhibition of P2Y1 receptors with the specific antagonist MRS2216 did not mimic the effects of oATP on TNF-alpha-stimulated IL-8 secretion. Although 1321N1 astrocytes lack expression of any known P2 receptor subtypes, oATP markedly inhibited ecto-ATPase activity in these cells, resulting in a significant accumulation of extracellular ATP. In summary, oATP can attenuate proinflammatory signaling by mechanisms independent of the expression or activation of known P2 receptor subtypes.
