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

To study double-strand break (DSB)-induced mutations in mammalian chromosomes, we stably transfected thymidine kinase (tk)-deficient mouse fibroblasts with a DNA substrate containing a recognition site for yeast endonuclease I-SceI embedded within a functional tk gene. Cells were then electroporated with a plasmid expressing endonuclease I-SceI to induce a DSB, and clones that had lost tk function were selected. In a previous study of DSB-induced tk-deficient clones, we found that approximately 8% of recovered tk mutations involved the capture of one or more DNA fragments at the DSB site. Almost half of the DNA capture events involved the I-SceI expression plasmid, and several events involved retrotransposable elements. To learn whether only certain DNA sequences or motifs are efficiently captured, in the current work we electroporated an I-SceI expression plasmid along with HaeIII fragments of φX174 genomic DNA. We report that 18 out of 132 tk-deficient clones recovered had captured DNA fragments, and 14 DNA capture events involved one or more fragments of φX174 DNA. Microhomology existed at most junctions between φX174 DNA and genomic sequences. Our work suggests that virtually any extrachromosomal DNA molecule may be recruited for the patching of DSBs in a mammalian genome.
