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

CRISPR/Cas9 is an efficient customizable nuclease to generate double-strand breaks (DSBs) in the genome. This process results in knockout of the targeted gene or knock-in of a specific DNA fragment at the targeted locus in the genome of various species. However, efficiency of knock-in mediated by homology-directed repair (HDR) pathway is substantially lower compared with the efficiency of knockout mediated by the nonhomologous end-joining (NHEJ) pathway. Suppressing NHEJ pathway or enhancing HDR pathway has been proven to enhance the nuclease-mediated knock-in efficiency in cultured cells and model organisms. We here investigated the effect of small molecules, Scr7, L755507 and resveratrol, on promoting HDR efficiency in porcine fetal fibroblasts. Results from eGFP reporter assay showed that these small molecules could increase the HDR efficiency by 2-3-fold in porcine fetal fibroblasts. When transfecting with the homologous template DNA and CRISPR/Cas9 plasmid and treating with small molecules, the rate of knock-in porcine fetal fibroblast cell lines with large DNA fragment integration could reach more than 50% of the screened cell colonies, compared with 26.1% knock-in cell lines in the DMSO-treated group. The application of small molecules offers a beneficial approach to improve the frequency of precise genetic modifications in primary somatic cells.
