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

ATP is known to act as an extracellular messenger mediating the propagation of Ca(2+) waves in astrocyte networks. ATP mediates Ca(2+) waves by activating P2Y purinoceptors, which mobilize intracellular Ca(2+) in astrocytes. A number of P2Y purinoceptor subtypes have been discovered, but it is not known which P2Y subtypes participate in transmitting astrocyte Ca(2+) waves. Here, we show that ATP analogs that are selective agonists for the P2Y(1) subtype of purinoceptor caused release of intracellular Ca(2+) in astrocytes from the dorsal spinal cord. The Ca(2+) responses were blocked by adenosine-3'-phospho-5'-phosphosulfate, an antagonist known to selectively inhibit P2Y(1) but not other P2Y purinoceptor subtypes. Also, we show that P2Y(1) mRNA is expressed in dorsal spinal cord astrocytes. Furthermore, expression of P2Y(1) in an astrocytoma cell line lacking endogenous purinoceptors was sufficient to permit propagation of intercellular Ca(2+) waves. Finally, Ca(2+) wave propagation in dorsal spinal cord astrocytes was suppressed by pharmacologically blocking P2Y(1) purinoceptors. Together, these results indicate that dorsal spinal astrocytes express functional P2Y(1) purinoceptors, which participate in the transmission of Ca(2+) waves. Ca(2+) waves in astrocytes have been implicated as a major signaling pathway coordinating glial and neuronal activity; therefore, P2Y(1) purinoceptors may represent an important link in cell-cell signaling in the CNS.
