Sox2 up-regulation and glial cell proliferation following degeneration of spiral ganglion neurons in the adult mouse inner ear.

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
In the present study, glial cell responses to spiral ganglion neuron (SGN) degeneration were evaluated using a murine model of auditory neuropathy. Ouabain, a well-known Na,K-ATPase inhibitor, has been shown to induce SGN degeneration while sparing hair cell function. In addition to selectively removing type I SGNs, ouabain leads to hyperplasia and hypertrophy of glia-like cells in the injured auditory nerves. As the transcription factor Sox2 is predominantly expressed in proliferating and undifferentiated neural precursors during neurogenesis,we sought to examine Sox2 expression patterns following SGN injury by ouabain. Real-time RT-PCR and Western blot analyses of cochlea indicated a significant increase in Sox2 expression by 3 days posttreatment with ouabain. Cells incorporating bromodeoxyuridine(BrdU) and expressing Sox2 were counted in the auditory nerves of control and ouabain-treated ears. The glial phenotype of Sox2+cells was identified by two neural glial markers: S100 and Sox10. The number of Sox2+ glial cells significantly increased at 3 days post-treatment and reached its maximum level at 7 days post-treatment. Similarly,the number of BrdU+ cells increased at 3 and 7 days post-treatment in the injured nerves. Quantitative analysis with dual-immunostaining procedures indicated that about 70% of BrdU+ cells in the injured nerves were Sox2+ glial cells. These results demonstrate that up-regulation of Sox2 expression is associated with increased cell proliferation in the auditory nerve after injury.
