Nuclear localization signals in phage terminal proteins provide a novel gene delivery tool in mammalian cells.

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
Terminal proteins (TPs) of bacteriophages prime DNA replication and become covalently linked to the genome ends. Unexpectedly, we have found functional eukaryotic nuclear localization signals (NLSs) within the TP sequences of bacteriophages from diverse families and hosts. Given the role of bacteriophages as vehicles for horizontal gene transfer (HGT), we postulated that viral genomes that have covalently linked NLS-containing terminal proteins might behave as vectors for HGT between bacteria and the eukaryotic nucleus. To validate this hypothesis, we profited from the in vitro Φ29 amplification system that allows the amplification of heterologous DNAs producing linear molecules of DNA with TP covalently attached to both 5' ends. Interestingly, these in vitro-generated TP-DNA molecules showed enhanced gene delivery in mammalian cells, supporting a possible role in HGT by transferring genes between prokaryotes and eukaryotes. Moreover, these TP-DNA molecules are a useful tool to amplify and subsequently deliver genes efficiently into the eukaryotic nucleus. Here, we suggest various possible applications and further developments of the technique with biotechnological and therapeutic purposes.
