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

backgroundGiven the high mortality rate and unclear pathogenesis for liver cancer, investigation of its molecular mechanisms is essential. We focused on the long non-coding RNA (lncRNA) MIR4435-2HG, which was recently reported to be oncogenic in lung cancer and the microRNA miRNA-487a, which has been reported to be oncogenic in hepatocellular carcinoma (HCC). Our aim was to determine if the former has a role in HCC, and to further validate the role of the latter.

methodsSamples from 64 patients with HCC were taken at The Third Affiliated Hospital of Sun Yat-Sen University. Cell transfection and PCR were applied.

resultsWe found that MIR4435-2HG and miRNA-487a were upregulated in tumor tissues compared to adjacent healthy tissues from HCC patients. The expression of MIR4435-2HG was significantly affected by tumor size but not by tumor metastasis. Correlation analysis showed that MIR4435-2HG and miRNA-487a were positively correlated in both the tumor tissues and adjacent healthy tissues from HCC patients. Overexpression of MIR4435-2HG led to upregulation of miRNA-487a in the cells of HCC cell lines, while overexpression of miRNA-487a did not significantly affect MIR4435-2HG. Overexpression of MIR4435-2HG and miRNA-487a promoted the proliferation of cells of HCC cell lines, and miRNA-487a knockdown partially attenuated the enhancing effects of MIR4435-2HG overexpression on cancer cell proliferation.

conclusionMIR4435-2HG is upregulated in HCC and promotes cancer cell proliferation possibly by upregulating miRNA-487a.
