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

Transcription activator-like effector nucleases (TALENs) and RNA-guided nucleases derived from clustered, regularly interspaced, short palindromic repeats (CRISPR)-Cas9 systems have become ubiquitous genome editing tools. Despite this, the impact that distinct high-order chromatin conformations have on these sequence-specific designer nucleases is, presently, ill-defined. The same applies to the relative performance of TALENs and CRISPR/Cas9 nucleases at isogenic target sequences subjected to different epigenetic modifications. Here, to address these gaps in our knowledge, we have implemented quantitative cellular systems based on genetic reporters in which the euchromatic and heterochromatic statuses of designer nuclease target sites are stringently controlled by small-molecule drug availability. By using these systems, we demonstrate that TALENs and CRISPR/Cas9 nucleases are both significantly affected by the high-order epigenetic context of their target sequences. In addition, this outcome could also be ascertained for S. pyogenes CRISPR/Cas9 complexes harbouring Cas9 variants whose DNA cleaving specificities are superior to that of the wild-type Cas9 protein. Thus, the herein investigated cellular models will serve as valuable functional readouts for screening and assessing the role of chromatin on designer nucleases based on different platforms or with different architectures or compositions.
