1 · What the graph read from it

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.

2 · The registry

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

The expression and physiology of purine receptors of the human blood-brain barrier endothelial cells were characterised by application of molecular biological, gene-silencing and Ca(2+)-imaging techniques to hCMEC/D3 cells. Reverse transcription polymerase chain reaction showed the expression of the G-protein-coupled receptors P2Y(2)-, P2Y(6)-, P2Y(11)- as well as the ionotropic P2X(4)-, P2X(5)- and P2X(7)-receptors. Fura-2 ratiometry revealed that adenosine triphosphate (ATP) or uridine triphosphate (UTP) mediated a change in the intracellular Ca(2+) concentration ([Ca(2+)](i)) from 150 to 300 nM in single cells. The change in [Ca(2+)](i) corresponded to a fourfold to fivefold increase in the fluorescence intensity of Fluo-4, which was used for high-throughput experiments. Pharmacological dissection using different agonists [UTPγS, ATPγS, uridine diphosphate (UDP), adenosine diphosphate (ADP), BzATP, αβ-meATP] and antagonist (MRS2578 or NF340) as well as inhibitors of intracellular mediators (U73122 and 2-APB) showed a PLC-IP(3) cascade-mediated Ca(2+) release, indicating that the nucleotide-induced Ca(2+) signal was mainly related to P2Y(2, 6 and 11) receptors. The gene silencing of the P2Y(2) receptor reduced the ATP- or UTP-induced Ca(2+) signal and suppressed the Ca(2+) signal mediated by P2Y(6) and P2Y(11) more specific agonists like UDP (P2Y(6)), BzATP (P2Y(11)) and ATPγS (P2Y(11)). This report identifies the P2Y(2) receptor subtype as the main purine receptor involved in Ca(2+) signalling of the hCMEC/D3 cells.
