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

MiR-21 is known to play an important role in the development and progression, including migration and invasion, of many malignancies including breast cancer. Accumulating evidence suggest that the induction of epithelial-mesenchymal transition (EMT) phenotype and acquisition of cancer stem cell (CSC) characteristics are highly interrelated, and contribute to tumorigenesis, tumor progression, metastasis, and relapse. The molecular mechanisms underlying EMT and CSC characteristics during miR-21 contributes to cell migration and invasion of breast cancer are poorly understood. Therefore, we established miR-21 re-expressing breast cancer MCF-7 (MCF-7/miR-21) cells, which showed increasing cell growth, migration and invasion, self-renewal and clonogenicity. Our data showed that re-expression of miR-21 induced the acquisition of EMT phenotype by activation of mesenchymal cell markers (N-cadherin, Vimentin, α-SMA) and inhibition of epithelial cell marker (E-cadherin) in MCF-7/miR-21 cells, which consistent with increased cell subpopulation expressing CSC surface markers (ALDH1(+) and CD44(+)/CD24(-/low)) and the capacity of sphereforming (mammospheres). Our results demonstrated that re-expression of miR-21 is responsible for migration and invasion by activating the EMT process and enhancing the characteristics of CSCs in MCF-7 cells.
