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

Somatic cell gene transfer has permitted inducible gene expression in vivo through coinfection of multiple viruses. We hypothesized that the highly efficient plasmid-based piggyBac transposon system would enable long-term inducible gene expression in mice in vivo. We used a multiple-transposon delivery strategy to create a tetracycline-inducible expression system in vitro in human cells by delivering the two genes on separate transposons for inducible reporter gene expression along with a separate selectable transposon marker. Evaluation of stable cell lines revealed 100% of selected clones exhibited inducible expression via stable expression from three separate transposons simultaneously. We next tested and found that piggyBac-mediated gene transfer to liver or lung could achieve stable reporter gene expression in mice in vivo in either immunocompetent or immune deficient animals. A single injection of piggyBac transposons could achieve long-term inducible gene expression in the livers of mice in vivo, confirming our multiple-transposon strategy used in cultured cells. The plasmid-based piggyBac transposon system enables constitutive or inducible gene expression in vivo for potential therapeutic and biological applications without using viral vectors.
