[Over-expression of human Notch ligand Delta-like 3 promotes proliferation of human gastric cancer cells
Article in Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo construct a eukaryotic expression plasmid carrying human full-length Notch ligand Delta-like 3 (DLL3) gene and study the effect of DLL3 knockdown and overexpression on the proliferation of gastric cancer cells
methodsHuman full-length DLL3 gene was amplified by PCR and cloned into the eukaryotic expression vector pCMV-Tag4. After verification by restriction enzymes and sequencing, the recombinant DLL3/pCMV-Tag4 vector was transiently transfected into HEK293T cells, in which the expressions of human DLL3 mRNA and protein were detected using real-time quantitative PCR and Western blotting, respectively. The expression of DLL3 in normal gastric epithelial cells and gastric cancer cell lines was detected by qRT-PCR and Western blotting. DLL3/pCMV-Tag4 was transfected into 3 gastric cancer cell lines, and their proliferation was assessed with MTT assay. Human gastric cancer cells MGC803 and MKN45 were also transfected with a specific human DLL3-siRNA to assess the effect of DLL3 down-expression on the cell proliferation.
resultsThe recombinant eukaryotic expression vector DLL3/pCMV-Tag4 was successfully constructed and human full-length DLL3 was expressed in HEK293T cells. MTT assay showed that DLL3 over-expression obviously promoted the proliferation and down-regulation of DLL3 inhibited the proliferation of the gastric cancer cells.
conclusionsDLL3 overexpression can promote the proliferation of gastric cancer cells
