RNA editing of the serotonin 2C receptor and expression of Galpha(q) protein: genetic mouse models do not support a role for regulation or compensation.
Article in Journal of neurochemistry, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The serotonin 2C (5-HT(2C)) receptor undergoes RNA editing at five bases in a region of the pre-mRNA encoding the second intracellular loop, generating many unique 5-HT(2C) receptor isoforms. Mechanisms regulating in vivo expression of different edited 5-HT(2C) receptor isoforms are poorly understood, as are the adaptive consequences of variation in editing profiles. Recent findings suggest a putative relationship between expression levels of Galpha(q/11) protein and the degree of editing of 5-HT(2C) receptor transcripts. To elucidate the potential regulatory or adaptive role of Galpha(q/11) protein levels, we quantified editing of 5-HT(2C) receptor RNA transcripts in Galpha(q) null mice and protein levels of Galpha(q) and Galpha(11) in transgenic male mice solely expressing either the non-edited (INI) or the fully edited (VGV) isoforms of the 5-HT(2C) receptor. Pyrosequencing of RNA isolated from amygdaloid cortex in Galpha(q) null and wild-type mice revealed no significant differences in 5-HT(2C) receptor mRNA editing profiles. Cortical tissue from INI/y, VGV/y, and wild-type mice was assayed for expression of Galpha(q) and Galpha(11) subunits by Western blotting. No differences in signal density between wild-type and INI/y or VGV/y groups were found, indicating equivalent levels of Galpha(q) and Galpha(11) protein. Together, these data do not support a causal or compensatory relationship between 5-HT(2C) receptor RNA editing and G(q) protein levels.
