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

backgroundAberrant expression of miR-224 is associated with tumor development and progression. This study investigated the role of miR-224 in esophageal squamous cell carcinoma (ESCC) ex vivo and in vitro.

methodsA total of 103 esophageal intraepithelial neoplasia, ESCC tissue specimens, and their matched distant normal tissues were collected to test miR-224 expression using qRT-PCR analysis. Western blot was used to quantify the level of PH domain leucine-rich repeat protein phosphatase 1 (PHLPP1) and PHLPP2 in ESCC tissues. Cell viability, apoptosis, invasion, and colony formation assays were used to assess the altered phenotypes of esophageal cancer cell lines after miR-224 expression or inhibition. A luciferase reporter assay was used to confirm miR-224 binding to PHLPP1 and PHLPP2 mRNA.

resultsmiR-224 was significantly overexpressed in esophageal intraepithelial neoplasia and ESCC tissues, while the expression of PHLPP1 and PHLPP2 proteins, the target genes of miR-224, was downregulated in ESCC tissues. miR-224 expression was associated with advanced clinical TNM stage, pathologic grade, and the level of PHLPP1 and PHLPP2 proteins in ESCC tissues. Ectopic overexpression of miR-224 promoted proliferation, migration, and invasion, but suppressed apoptosis of ESCC cells. miR-224 was able to bind to the 3' untranslated region (3'-UTR) of PHLPP1 and PHLPP2 mRNA to suppress their expression.

conclusionsThe current study demonstrated that miR-224 acts as an oncogenic miRNA in ESCC, possibly by targeting PHLPP1 and PHLPP2.
