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

backgroundMALAT1 was discovered as a prognostic marker for lung cancer metastasis and has been found upregulated in many types of tumor, but its transcriptional regulation mechanism in tumors remains unclear.

methodsA deletion analysis of MALAT1 promoter region was performed to find the cis elements that were critical for the transcriptional activation of MALAT1 gene. Reporter gene assays were employed to analyze the effect of Sp1 on the promoter activity of MALAT1 gene. The binding activity of Sp1 with the promoter of MALAT1 gene was examined by EMSA and ChIP assay. Effects of Sp1 on regulation of MALAT1 were analyzed by RNA interference in vitro and in vivo mouse model.

resultsBy means of luciferase assay, Sp1 was found to activate the promoter of the human MALAT1 gene. The binding of Sp1 to this region was also detected by electrophoretic mobility shift and chromatin immunoprecipitation assays. Sp1 knockdown also decreased the MALAT1 and inhibited A549 lung cancer cells' growth and invasion in vitro. Furthermore, knockdown of Sp1 also mimicked the inhibition of MALAT1 in A549 lung cancer cells' growth and metastasis in vivo.

conclusionsTaken together, our data suggest that upregulation of MALAT1 was mediated by the transcription factor Sp1 in A549 lung cancer cells, and Sp1 could be therapeutic target for cancer.
