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

Homologous recombination in gene targeting in most organisms occurs by an inefficient mechanism. Inducing a double-strand break in the chromosomal target may increase this efficiency by allowing recombination to proceed by the highly efficient single-strand annealing mechanism. A gene targeting experiment was modeled in Xenopus oocytes by using a circular plasmid to mimic the chromosomal target site and a homologous linear molecule (pick-up fragment or PUF) as an analogue of the vector DNA. When those two molecules were simply injected together, no recombination was observed. In contrast, when the circular plasmid was cleaved in vivo by injection of the site-specific endonuclease, I-Sce I, relatively efficient intermolecular recombination occurred, involving up to 17% of the cleaved molecules. Recombination was dependent on the stability of the PUF; product yield was increased by using longer fragments and by injecting larger amounts of linear DNA, both of which increased the lifetime of the PUF in the oocytes. These results demonstrate that in vivo double-strand breaks can induce homologous recombination of reluctant substrates and may be useful in augmenting the efficiency of gene targeting.
