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

backgroundMicroRNAs (miRs) are small non-coding RNAs that play important roles in cancer development where they can act as oncogenes or as tumor-suppressors. MiR-34a is a tumor suppressor that is frequently downregulated in a number of tumor types. However, little is known about the role of miR-34a in colorectal cancer (CRC).

aimThis study aims to show the dysregulation of miR-34a in CRC and to characterize the function and mechanism of miR-34a in CRC cell lines.

methodsThe expression of miR-34a was detected using real-time PCR on CRC tissues and adjacent non-tumorous tissues. The ELISA was used to assess vascular endothelial growth factor (VEGF). The focal adhesion kinase (FAK) and phosphorylated FAK Y397 (pY397FAK) were measured by Western blot. The functions of miR-34a in vivo were measured by migration, invasion, CCK-8 assay and flow cytometry.

resultsMiR-34a was significantly downregulated and pY397FAK was upregulated in CRC cancer tissues. It plays an important role in inhibiting migration and invasion and in increasing apoptosis of CRC cells. Bioinformatic analysis suggested that VEGF may be a target of miR-34a, and this hypothesis was proved by ELISA and RT-PCR. The level of pY397FAK that could be activated by VEGF was downregulated in miR-34a overexpression CRC cell lines. The phosphorylation of FAK at 397 sites in miR-34a-stable cell lines was completely rescued by extra VEGF treatment.

conclusionMiR-34a is frequently downregulated in CRC and modulates the phosphorylation of FAK by negatively regulating VEGF.
