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

Safe, effective, and tissue-specific delivery is a central issue for the therapeutic application of nucleic-acid-based gene interfering agents, such as ribozymes and siRNAs. In this study, we constructed a functional RNase P-based ribozyme (M1GS RNA) that targets the overlapping mRNA region of M80.5 and protease, two murine cytomegalovirus (MCMV) proteins essential for viral replication. In addition, a novel attenuated strain of Salmonella, which exhibited efficient gene transfer activity and little cytotoxicity and pathogenicity in mice, was constructed and used for delivery of anti-MCMV ribozyme. In MCMV-infected macrophages treated with the constructed attenuated Salmonella strain carrying the functional M1GS RNA construct, we observed an 80-85% reduction in the expression of M80.5/protease and a 2,500-fold reduction in viral growth. Oral inoculation of the attenuated Salmonella strain in mice efficiently delivered antiviral M1GS RNA into spleens and livers, leading to substantial expression of the ribozyme without causing significant adverse effects in the animals. Furthermore, the MCMV-infected mice that were treated orally with Salmonella carrying the functional M1GS sequence displayed reduced viral gene expression, decreased viral titers, and improved survival compared to the untreated mice or mice treated with Salmonella containing control ribozyme sequences. Our results provide direct evidence that oral delivery of M1GS RNA by Salmonella-based vectors effectively inhibits viral gene expression and replication in mice. Moreover, this study demonstrates the utility of Salmonella-mediated oral delivery of RNase P ribozyme for gene-targeting applications in vivo.
