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

MicroRNAs (miRs) are a class of small non-coding RNAs that function as mediators of gene expression. Dysregulations of miRs have been implicated in the development and progression of glioma. In the present study, we investigated the role of miR-133b in mediating the proliferation and invasion of glioma cells, and the potential mechanism. Real-time RT-PCR results showed that miR-133b expression was significantly decreased in glioma tissues compared with normal brain tissues. Luciferase reporter assay further identified silent information regulator 1 (Sirt1) as a novel direct target of miR-133b in glioma U87 cells. Overexpression of miR-133b suppressed Sirt1 expression and reduced the proliferation and invasion of U87 cells, which could be partly rescued by forced expression of Sirt1. In addition, the Sirt1 mRNA level was significantly higher in glioma tissues than in normal brain tissues, and was inversely correlated with miR-133b level in glioma tissues. In summary, our study sheds light on the regulatory mechanism of miR-133b in glioma growth and metastasis via direct mediation of Sirt1 expression, and suggests that Sirt1 may serve as a potential therapeutic target for glioma.
