CAP2 contributes to tumorigenesis in gastric cancer by targeting transcription factor SOX9.

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
backgroundGastric cancer (GC) is one of the most common tumors and the major cause of cancer-related mortality in the world. The purpose of this study is to identify new biomarker and reveal its potential molecular mechanism in GC.
methodsThe expression of CAP2 was observed by the bioinformatics analysis and western blot assays. The effects of CAP2 on cell proliferation and growth were tested by MTT assay, EdU assay, colony formation assay, and flow cytometric assay, respectively. ChIP and dual-luciferase assays were confirmed that SOX9 binding sites were putative regulatory elements in the transcriptional activation of CAP2. Furthermore, western blot and xenograft assays were applied to examine whether SOX9 was involved in the regulation of CAP2 expression.
resultsWe reported that CAP2 is overexpressed in GC cells and tissues and related to a poorer prognosis for GC patients. Moreover, we found that knockdown of CAP2 suppressed the proliferation, growth, and cell cycle of GC cells. Besides, the transcription factor SOX9 participated in the CAP2-mediated proliferation of GC cells
conclusionsOur results provide novel evidence that CAP2 plays an essential role in the genesis and development of GC, thus potentially highlighting this gene as a therapeutic target.
