[Investigation of Gene Expression Profile of A549 Cells after Overexpression of GPC5 by High Throughput Transcriptome Sequencing].
Article in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundGlypican-5 (GPC5) is an important tumor suppressor, while little is known about the impact of GPC5 on proliferation ability and gene expression in lung adenocarcinoma cell lines. Here, we stably overexpressed GPC5 in A549 cells and investigated the impact of cell proliferation ability and gene expression.
methodsA549 cells that stably overexpressed GPC5 were constructed by lentivirus. Cell counter kit 8 (CCK8), colony formation, EdU assay were conducted to analyze cell proliferation ability, and transcriptome sequencing was utilized to investigate gene expression profile.
resultsCCK8 assay showed that compared with empty vector, overexpression of GPC5 significantly inhibited cell proliferation rate in A549 cells and the number of colony was also decreased (181±17 vs 278±23). EdU assay also confirmed the percentage of positive staining cells decreased after GPC5 overexpression. Transcriptome sequencing revealed that 2,108 genes were differentially expressed after GPC5 overexpression. Among these differentially expressed genes, 47 genes of the Gene Ontology item "positive regulation of cell proliferation" were downregulated.
conclusionsOverexpression of GPC5 inhibited proliferation ability in lung adenocarcinoma A549 cells and genes with the function of "positive regulation of cell proliferation" were downregulated.
