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

Serotonin 2C receptor (5-HT(2C)R) exerts a major inhibitory influence on dopamine (DA) neurotransmission within the mesocorticolimbic DA pathway that is implicated in drug reward and goal-directed behaviors. 5-HT(2C)R pre-mRNA undergoes adenosine-to-inosine editing, generating numerous receptor isoforms in brain. As editing influences 5-HT(2C)R activity, individual differences in editing might influence dopaminergic function and, thereby, contribute to interindividual vulnerability to drug addiction. Liability to drug-related behaviors in rats can be predicted by their level of motor activity in response to a novel environment. Rats with a high locomotor response (high responders; HRs) exhibit enhanced acquisition and maintenance of drug self-administration compared to rats with a low response (low responders; LRs). We here examined 5-HT(2C)R mRNA editing and expression in HR and LR phenotypes to investigate the relationship between 5-HT(2C)R function and behavioral traits relevant to drug addiction vulnerability. Three regions of the mesocorticolimbic circuitry (ventral tegmental area (VTA), nucleus accumbens (NuAc) shell, and medial prefrontal cortex (PFC)) were examined. 5-HT(2C)R mRNA expression and editing were significantly higher in the NuAc shell compared with both the PFC and VTA, implying significant differences in function (including constitutive activity) among 5-HT(2C)R neuronal populations within the circuitry. The regional differences in editing could, at least in part, arise from the variations in expression levels of the editing enzyme, ADAR2, and/or from the variations in the ADAR2/ADAR1 ratio observed in the study. No differences in the 5-HT(2C)R expression were detected between the behavioral phenotypes. However, editing was higher in the PFC of HRs vs LRs, implicating this region in the pathophysiology of drug abuse liability.
