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

backgroundEvidence indicates that the cerebellum plays a role in genetic predilection to excessive alcohol (ethanol [EtOH]) consumption in rodents and humans, but the molecular mechanisms mediating such predilection are not understood. We recently determined that EtOH has opposite actions (enhancement or suppression) on tonic GABAA receptor (GABAA R) currents in cerebellar granule cells (GCs) in low- and high-EtOH-consuming rodents, respectively, and proposed that variation in GC tonic GABAA R current responses to EtOH contributes to genetic variation in EtOH consumption phenotype.

methodsVoltage-clamp recordings of GCs in acutely prepared slices of cerebellum were used to evaluate the effect of EtOH on GC tonic GABAA R currents in another high-EtOH-consuming rodent, prairie voles (PVs).

resultsEtOH (52 mM) suppressed the magnitude of the tonic GABAA R current in 57% of cells, had no effect in 38% of cells, and enhanced the tonic GABAA R current in 5% of cells. This result is similar to GCs from high-EtOH-consuming C57BL/6J (B6) mice, but it differs from the enhancement of tonic GABAA R currents by EtOH in low-EtOH-consuming DBA/2J (D2) mice and Sprague Dawley (SD) rats. EtOH suppression of tonic GABAA R currents was not affected by the sodium channel blocker, tetrodotoxin (500 nM), and was independent of the frequency of phasic GABAA R-mediated currents, suggesting that suppression is mediated by postsynaptic actions on GABAA Rs, rather than a reduction of GABA release. Finally, immunohistochemical analysis of neuronal nitric oxide synthase (nNOS; which can mediate EtOH enhancement of GABA release) demonstrated that nNOS expression in the GC layer of PV cerebellum was similar to the levels seen in B6 mice, both being significantly reduced relative to D2 mice and SD rats.

conclusionsCombined, these data highlight the GC GABAA R response to EtOH in another species, the high-EtOH-consuming PV, which correlates with EtOH consumption phenotype and further implicates the GC GABAA R system as a contributing mechanism to high EtOH consumption.
