DUSP5 Downregulation in Nucleus Accumbens Core Correlates with Cocaine-Induced Maladaptive Synaptic Plasticity.

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
The United States is currently facing a drug overdose epidemic. The nucleus accumbens core (NAcore), a brain region critical for reward and aversion behaviors, undergoes structural and functional synaptic adaptations in response to chronic drug exposure. However, the molecular mechanisms underlying these adaptations remain poorly understood. In this study, we investigate the role of dual-specificity phosphatase 5 (DUSP5), a phosphatase known to deactivate extracellular signal-regulated kinase (ERK), in cocaine-induced neuroplasticity. While prior research has linked other DUSP family members to various drugs of abuse, the specific role of DUSP5 in cocaine addiction remains unexplored. We hypothesized that lack of DUSP5 contributes to cocaine-induced maladaptive synaptic plasticity in NAcore. To test this, we employed a rat cocaine self-administration model and molecular analyses and mined publicly available single-cell RNA sequencing data from cocaine-treated NAcore. Our findings reveal a role for DUSP5 in cocaine-related synaptic and behavioral adaptations, highlighting DUSP5 and DUSP5-associated signaling pathways as potential mechanisms underlying substance use disorders and as candidates for therapeutic intervention.
