Expression of HDAC3-Y298H Point Mutant in Medial Habenula Cholinergic Neurons Has No Effect on Cocaine-Induced Behaviors.
Article in eNeuro, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Histone deacetylase 3 (HDAC3) is one of the most highly expressed HDACs in the brain shown to be a negative regulator of long-term memory formation. HDAC3 has also been shown to be involved in cocaine-associated behaviors, demonstrated by manipulations in the nucleus accumbens. Previous studies have demonstrated that expression of a dominant negative of a key HDAC3 target gene, nuclear receptor subfamily 4 group A member 2 (NR4A2), in cholinergic neurons of the medial habenula (MHb) blocked reinstatement of cocaine-induced conditioned place preference (CPP) as well as cue-induced intravenous self-administration (IVSA). Together, these findings suggested that HDAC3 would also be important for MHb-dependent reinstatement of CPP and IVSA, which we examined in this study. Contrary to our hypothesis, our results found that expression of an HDAC3 deacetylase dead point mutant within the cholinergic neurons of the mouse MHb had no effect on reinstatement or other cocaine-induced behaviors.
