Cloning and expression of the functional human anti-vascular endothelial growth factor (VEGF) using the pcDNA3.1 vector and the human chronic myelogenous leukemia cell line K562.

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
In this study, the light chain (κ) and heavy chain (γ) sequences of the monoclonal antibody against vascular endothelial growth factor (VEGF) were sub-cloned into the eukaryotic pcDNA3.1 (+) (Hygro) and the pcDNA3.1 (+) (Neo) expression vectors using the traditional and homologous recombination methods. To express the antibody, the recombinant plasmids were transfected into the Chinese hamster ovary (CHO) and the K562 cell lines. The recombinant antibody was then purified using the protein A affinity chromatography. Furthermore, in order to demonstrate the inhibition of VEGF-induced mitogenesis of the recombinant antibody, the bovine aorta endothelial like cells were employed. The results showed specialization and conjunction of the recombinant antibody to the VEGF. It was also indicated that the antibody expression in the K562 cell lines was higher than the CHO cell lines. Furthermore, the in vitro VEGF inhabitation of the recombinant antibodies which were produced from the K562 cell line, and the CHO cell line, were similar. This proved that the K562 cell line is a good substitute for the CHO cell line in the production of the recombinant antibodies.
