Subregional Expression of Hippocampal Glutamatergic and GABAergic Genes in F344 Rats with Social Isolation after Weaning.

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
Many studies have shown that postweaning social isolation (pwSI) alters various behavioral phenotypes, including hippocampusdependent tasks. Here, we report the comprehensive analysis of the expression of glutamatergic and GABAergic neurotransmissionrelated genes in the distinct hippocampal subregions of pwSI rats. Male F344 rats (age, 4 wk) experienced either pwSI or group housing (controls). At 7 wk of age, the hippocampus of each rat was removed and laser-microdissected into the CA1 and CA3 layers of pyramidal cells and the granule cell layer of the dentate gyrus. Subsequently, the expression of glutamatergic- and GABAergic- related genes was analyzed by quantitative RT-PCR. In the CA1 and CA3 pyramidal cell layers, 18 of 24 glutamate receptor subunit genes were at least 1.5-fold increased in expression after pwSI. In particular, the expression of several N-methyl-D-aspartate and kainate receptors (for example, Grin2a in CA1, Grik4 in CA3) was significantly increased after pwSI. In contrast, pwSI tended to decrease the expression of GABAA receptor subunit genes, and Gabra1, Gabra2, Gabra4, Gabra5, Gabrb2, Gabrg1, and Gabrg2 were all significantly decreased in expression compared with the levels in the group-housed rats. These results indicate a subregion- specific increase of glutamate receptors and reduction of GABAA receptors, suggesting that the hippocampal circuits of pwSI rats may be in more excitable states than those of group-housed rats.
