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

Long-term memory formation requires selective changes in gene expression. Here, we determined the contribution of chromatin remodeling to learning-induced changes in brain-derived neurotrophic factor (bdnf) gene expression in the adult hippocampus. Contextual fear learning induced differential regulation of exon-specific bdnf mRNAs (I, IV, VI, IX) that was associated with changes in bdnf DNA methylation and altered local chromatin structure. Infusions of zebularine (a DNA methyltransferase inhibitor) significantly altered bdnf DNA methylation and triggered changes in exon-specific bdnf mRNA levels, indicating that altered DNA methylation is sufficient to drive differential bdnf transcript regulation in the hippocampus. In addition, NMDA receptor blockade prevented memory-associated alterations in bdnf DNA methylation, resulting in a block of altered bdnf gene expression in hippocampus and a deficit in memory formation. These results suggest epigenetic modification of the bdnf gene as a mechanism for isoform-specific gene readout during memory consolidation.
