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

Peripheral nerve injury is a complex biological process that involves the expression changes of various coding and non-coding RNAs. Previously, a number of novel miRNAs that were dysregulated in rat sciatic nerve stumps after peripheral nerve injury were identified and functionally annotated by Solexa sequencing. In the current study, we studied one of these identified novel miRNAs, miR-3075, in depth. Results of transwell-based cell migration assay showed that increased expression of miR-3075 suppressed the migration rate of Schwann cells while decreased expression of miR-3075 elevated the migration rate of Schwann cells, demonstrating that miR-3075 inhibited Schwann cell migration. Results of BrdU cell proliferation assay showed that neither miR-3075 mimic nor miR-3075 inhibitor would affect Schwann cell proliferation. We further studied candidate target genes of miR-3075 by using bioinformatic tools and analyzing gene expression patterns and found that miR-3075 might target contactin 2 (Cntn2). Previous study showed that Cntn2 regulated cell migration and myelination. Our current observation suggested that the biological effects of miR-3075 on Schwann cell phenotype might by through the negative regulation of Cntn2. Overall, our study revealed the function of a novel miRNA, miR-3075, and expanded our current understanding of the molecular mechanisms underlying peripheral nerve injury and regeneration.
