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

Quantification of a plasmid DNA (pDNA) and investigation of its polymer-associated state in the nucleus are crucial to evaluate the effectiveness of a gene-delivery system. This study was conducted with p3NF-luc-3NF, a pDNA-bearing optimized kappaB motif to favour NFkappaB-driven nuclear import. Here, a quantification of pDNA copies in the nucleus was performed by real-time confocal laser scanning microscopy in HeLa and C2C12 cells transfected with linear polyethylenimine or histidylated polylysine. Förster Resonance Energy Transfer (FRET) from the fluorescein-p3NF-luc-3NF donor to the co-localized rhodamine-polymer acceptor was carried out to investigate whether the pDNA was still condensed with the polymer in the nucleus. Upon 5 h of transfection, the nuclear amount of p3NF-luc3NF was approximately 1500 copies in both cell lines whereas that of pTAL-luc, a 3NF-free counterpart pDNA, was less than 250. This quantity of p3NF-luc-3NF dropped dramatically to that of pTAL-luc in the presence of the BAY 11-7085, an inhibitor of NFkappaB activation. These data strongly support a nuclear import of p3NF-luc3NF mediated by NFkappaB. Moreover, FRET experiments clearly revealed that most of nuclear pDNA were still condensed with the polymer raising the question of their passage through the nuclear pore complex and their impact on the gene-expression efficiency.
