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

backgroundDevelopment of VEGF antagonists, which inhibit its interaction with the receptors, is a widely used strategy for the inhibition of angiogenesis and tumor growth.

objectivesIn the present study, a VEGFR-1 antagonistic peptide was designed and its potential for binding to VEGFR-1 and VEGFR-2 was evaluated by theoretical studies. MATERIALS AND

methodsBased on the X-ray structure of VEGF-B/VEGFR-1 D2 (PDB ID: 2XAC), an antagonistic peptide (known as VGB1) was designed, and its model structure was constructed using homology modeling in the MODELLER, version 9.16. The validity of the modeled structures was estimated employing several web tools. Finally, one model was chosen and molecular dynamics (MD) simulation was applied using the GROMACS package, version 5.1.4, to allow conformational relaxation of the structure. Next, docking process of the peptide with VEGFR-1 and VEGFR-2 was performed by HADDOCK web server and the docking structures were optimized by MD simulation for 20 ns. The far-UV circular dichroism (CD) spectrum of VGB1 was recorded to evaluate the overall structure of the peptide.

resultsThe far-UV CD spectrum indicated that VGB1 contains α helix structure. The results from docking studies suggested that Van der Waals and nonpolar interactions play the most important role in the peptide binding to VEGFR-1. In addition, our results implicated the relevance of both Van der Waals and electrostatic interactions in the formation of complex between VGB1 and VEGFR-2. In addition to the common binding residues in the corresponding region of VEGF-A and VEGF-B, additional binding residues also were predicted for the interaction of VGB1 with VEGFR-1 and VEGFR-2.

conclusionsThe results of MD and molecular docking simulations predicted that VGB1 recognizes both VEGFR-1 and VEGFR-2, which may lead to the prevention of the downstream signaling triggered by these receptors.
