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

Accumulating evidence suggests a critical role for epigenetic regulations in long term memory (LTM) formation. Among them, post-translational modifications of proteins, as histone acetylation, are an important regulator of chromatin remodelling and gene transcription. While the implication of histone acetylation in memory consolidation is widely accepted, less is known about its role in memory reconsolidation i.e. during memory restabilization after its reactivation. In the present study, we investigated the role of histone acetylation during the initial consolidation and the reconsolidation of spatial memory, using a weak massed learning procedure in the Morris water maze paradigm in mice. Usually a weak learning is sufficient for short term memory (STM) formation, but insufficient to upgrade STM to LTM. We found that promoting histone acetylation through intra-hippocampal infusion of a class I selective histone deacetylase (HDAC) inhibitor immediately after a subthreshold spatial learning improved LTM but not STM retention. More importantly, inhibiting HDAC activity after the reactivation of a weak memory promoted specifically LTM reconsolidation without affecting post-reactivation STM. These findings argue in favour of an important role for histone acetylation in memory consolidation, and more particularly during the reconsolidation of spatial memory in mice.
