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

purposeLong noncoding RNA (lncRNA) have been reported to be involved in the development of multiple cancers. The aim of this study was to report the identification of lncRNA-CTD-2108O9.1, which we have named lncRNA low expressed in gastric cancer (lncRNA-LOWEG), and investigate its role in cancer development.

methodsTotal RNA was extracted from the tissues of 94 patients with GC, one normal gastric epithelial cell line and four GC cell lines. Expression levels of lncRNA-LOWEG were determined by real-time PCR. Moreover, CCK-8 proliferation assay, transwell cell invasion assay and flow cytometry were performed to study the effects of lncRNA-LOWEG on SGC-7901 cell proliferation, cell invasion and cell cycle progression. Lastly, western blot and real-time PCR were used to verify the potential target genes of lncRNA-LOWEG.

resultsSignificantly reduced expression of lncRNA-LOWEG was found in gastric cancer tissues and cell lines (SGC-7901, AGS, BGC-823 and HG-27) compared with patient-matched nontumorous adjacent tissues (P < 0.01) or the normal gastric cell line GES-1 (P < 0.05). Moreover, the transwell assay showed that the number of cells capable of passing through the Matrigel was significantly reduced after lncRNA-LOWEG transfection (P < 0.05). However, lncRNA-LOWEG overexpression did not significantly influence cell proliferation (P > 0.05) and cell cycle progression (P > 0.05). Lastly, western blot and real-time PCR analysis suggested that lncRNA-LOWEG is positively correlated with the expression of leukemia inhibitory factor receptor (LIFR) gene at the translational level.

conclusionsLncRNA-LOWEG is a tumor suppressor that inhibits GC cell invasion. And LIFR gene is up-regulated by lncRNA-LOWEG.
