mPFC DUSP1 mediates adolescent cocaine exposure-induced higher sensitivity to drug in adulthood.
Article in EMBO reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Adolescent cocaine abuse increases the risk for developing addiction in later life, but the underlying molecular mechanism remains poorly understood. Here, we establish adolescent cocaine-exposed (ACE) male mouse models. A subthreshold dose of cocaine (sdC) treatment, insufficient to produce conditioned place preference (CPP) in adolescent mice, induces CPP in ACE mice during adulthood, along with more activated CaMKII-positive neurons, higher dual specificity protein kinase phosphatase-1 (Dusp1) mRNA, lower DUSP1 activity, and lower DUSP1 expression in CaMKII-positive neurons in the medial prefrontal cortex (mPFC). Overexpressing DUSP1 in CaMKII-positive neurons suppresses neuron activity and blocks sdC-induced CPP in ACE mice during adulthood. On the contrary, depleting DUSP1 in CaMKII-positive neurons activates more neurons and further enhances sdC-induced behavior in ACE mice during adulthood. Also, ERK1/2 might be a downstream signal of DUSP1 in the process. Our findings reveal a role of mPFC DUSP1 in ACE-induced higher sensitivity to the drug in adult mice. DUSP1 might be a potential pharmacological target to predict or treat the susceptibility to addictive drugs caused by adolescent substance use.
