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

Following spinal cord injury (SCI), limit spontaneous functional recovery often emerged. However, the neuronal mechanisms associated with this phenomenon still remains obscure. By using proteomics analysis, endoplasmic reticulum protein 29 (ERp29) was discovered to increase in the motor cortexes of spinal cord transection (SCT) rats for 28 days post-operation (dpo) compared with in 14dpo. Then, the change in the expression of ERp29 was confirmed by using reverse transcription polymerase chain reaction (RT-PCR) and Western blot. To determine the role of ERp29 in the recovery of locomotor functions following SCT, lentiviral vectors were used to up- and downregulate the expression level of ERp29. Here, we found that cortical neurons in vitro with high level of ERp29 expression exhibited a significant proliferation, characterized by smaller size of soma and more extensive axon outgrowth, compared with neurons used as control, while ERp29 silence got the opposite results. In vivo, Lentivirus was inject into the cerebral cortex following SCT at thoracic level 10, which resulted in an increase number of neuronal nuclei(NeuN)-positive cells and less apoptotic cells. Moreover, increased PKC-γ immunoreactivity density was also found in the spinal cord T9 level compared with control rats. This was associated with a great functional improvement, indicated by Basso, Beattie, Bresnahan (BBB) locomotor rating scale. Lastly, we verified that ERp29 acts as a regulator by regulating a group of genes related with cell survival and apoptosis, involving in caspase and Erk, but not PI3K. Our findings showed that ERp29 can improve locomotor function by promoting neuronal survival and axonal regeneration in SCT rats via caspase and Erk signal pathway.
