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

Gene therapy with Plasmid AMEP (antiangiogenic metargidin peptide) has recently been studied as a potential targeted therapy for melanoma. This plasmid is designed to downregulate α5β1 and αvβ3 integrins. In our study, electroporation was used as a nonviral delivery system. We investigated the antiangiogenic and direct antitumor effectiveness of this gene therapy on low and highly metastatic B16 melanoma variants. In vitro, the antiangiogenic effectiveness as determined by tube formation assay on endothelial cells was predominantly dependent on AMEP expression levels. In vivo, antitumor effectiveness was mediated by the inhibition of proliferation, migration and invasion of melanoma cells and correlated with the expression of integrins on tumor cells after intratumor delivery. In addition, reduced metastatic potential was shown. Intramuscular gene electrotransfer of Plasmid AMEP, for AMEP systemic distribution, had no antitumor effect with this specific preventive treatment protocol, confirming that direct tumor delivery was more effective. This study confirms our previous in vitro data that the expression levels of integrins on melanoma cells could be used as a biomarker for antitumor effectiveness in integrin-targeted therapies, whereas the expression levels of AMEP peptide could be a predictive factor for antiangiogenic effectiveness of Plasmid AMEP in the treatment of melanoma.
