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

aimsGrowing evidence implicates dysfunctional myelin in the pathogenesis of temporal lobe epilepsy (TLE). Connexin 47 (Cx47), an oligodendrocytic gap junction protein, maintains myelin integrity. This study investigates the role of Cx47 in myelin impairment and seizure progression in TLE.

methodsCx47 and phosphorylated Cx47 (p-Cx47) expression was analyzed in human and mouse TLE brain tissues via Western blot and immunofluorescence. Candidate Cx47 phosphorylation kinases revealed by single-cell RNA sequencing were validated through immunofluorescence, protein docking, and co-immunoprecipitation. TLE mice were treated with the CaMKII inhibitor KN93 to evaluate its effects on demyelination and seizure burden.

resultsIn a experimental mouse model, phosphorylated Cx47 (p-Cx47) was significantly upregulated, recapitulating a similar trend observed in human TLE tissues. This upregulation was accompanied by marked demyelination in the TLE animals. In mice, increased levels of Cx47 and p-Cx47 were associated with elevated CaMKII and phosphorylated CaMKII (p-CaMKII). The interaction between Cx47 and CaMKII was further confirmed. Moreover, administration of KN93 suppressed the upregulation of Cx47 and p-Cx47, thereby mitigating demyelination and reducing seizure progression.

conclusionsCaMKII-mediated Cx47 expression and phosphorylation promote demyelination and seizure progression in TLE. Targeting Cx47 phosphorylation may offer a therapeutic strategy for TLE.
