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

Various methods have been used in targeted gene knock-in applications. CRISPR-based knock-in strategies based on homology-independent repair pathways such as CRISPR HITI have been shown to possess the best efficiency for gene knock-in in mammalian cells. However, these methods suffer from the probability of plasmid backbone insertion at the target site. On the other hand, studies trying to combine the targeting ability of the Cas9 molecule and the excision/integration capacity of the PB transposase have shown random integrations. In this study, we introduce a new homology-independent knock-in strategy, Transposase-CRISPR mediated Targeted Integration (TransCRISTI), that exploits a fusion of Cas9 nuclease and a double mutant piggyBac transposase. In isogenic mammalian cell lines, we show that the TransCRISTI method demonstrates higher efficiency (72%) for site-specific insertions than the CRISPR HITI (44%) strategy. Application of the TransCRISTI method resulted in site-directed integration in 4.13% and 3.69% of the initially transfected population in the human AAVS1and PML loci, respectively, while the CRISPR HITI strategy resulted in site-directed integration in the PML locus in only 0.6% of cells. We also observed lower off-target and random insertions in the TransCRISTI group than the CRISPR HITI group. The TransCRISTI technology represents a great potential for the accurate and high-efficiency knock-in of the desired transposable elements into the predetermined genomic locations.
