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

background and purposeAxonal remodeling is critical to brain repair after stroke. The present study investigated axonal outgrowth after stroke and the signaling pathways mediating axonal outgrowth in cortical neurons.

methodsUsing a rodent model of middle cerebral artery occlusion, we examined high-molecular weight neurofilament (NFH) immunoreactive axons and myelin basic protein-positive oligodendrocytes in the peri-infarct area. In vitro, using cultured cortical neurons in a microfluidic chamber challenged by oxygen-glucose deprivation (OGD), we investigated mechanisms selectively regulating axonal outgrowth after OGD.

resultsNFH(+) axons and MBP(+) oligodendrocytes substantially increased in the peri-infarct area during stroke recovery, concomitantly with an increase in dendrites and spines identified by Golgi-Cox staining. In vitro, cortical neurons subjected to OGD exhibited significant increases in axonal outgrowth and in phosphorylated NFH protein levels, concurrently with downregulation of phosphatase tensin homolog deleted on chromosome 10, activation of Akt, and inactivation of glycogen synthase kinase-3β in regenerated axons. Blockage of phosphoinositide 3-kinase with pharmacological inhibitors suppressed Akt activation and attenuated phosphorylation of glycogen synthase kinase-3β, which resulted in suppression of phosphorylated NFH and axonal outgrowth after OGD; whereas GSK-3 inhibitors augmented axonal regeneration and elevated phosphorylated NFH levels after OGD.

conclusionsStroke induces axonal outgrowth and myelination in rodent ischemic brain during stroke recovery, and the phosphoinositide 3-kinase/Akt/glycogen synthase kinase-3β signaling pathway mediates axonal regeneration of cortical neurons after OGD.
