Regulation of the nicotinic receptor alpha7 subunit by chronic stress and corticosteroids.
Article in Brain research, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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 alpha7 subunit of the nicotinic acetylcholine receptor (NAchRalpha7) is one of the principal brain receptors for nicotine and is thought to be a mediator of nicotine's pro-cognitive effects. While nicotine is known to interact with the stress axis, little is known about the effect of stress or corticosteroids on the expression in the hippocampus, a brain region important to both cognition and stress reactivity. We examined the effects of chronic (21 day) restraint stress (CRS) and adrenalectomy with hormone replacement with the selective mineralocorticoid receptor (MR) agonist aldosterone, the selective glucocorticoid receptor (GR) agonist RU28,362 or corticosterone for 7 days, on the hippocampal expression of NAchRalpha7 mRNA and protein, as measured by (125)I alpha-Bungarotoxin autoradiography. We found that CRS increased the levels of NAchRalpha7 mRNA in the CA1, CA3 and dentate gyrus while levels of the protein were lowered by the same treatment. Corticosteroid replacement showed a GR specific increase in NAchRalpha7 mRNA, consistent with a corticosteroid mediated effect of CRS. While the mechanism behind these observations is as yet unclear, they may be neuroprotective against the damaging effects of CRS or an example of adaptation to the allostatic load produced by CRS.
