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

The progress in development of synthetic gene circuits has been hindered by the limited repertoire of available transcription factors. Recently, it has been greatly expanded using the CRISPR/Cas9 system. However, this system is limited by its imperfect DNA sequence specificity, leading to potential crosstalk with host genome or circuit components. Furthermore, CRISPR/Cas9-mediated gene regulation is context dependent, affecting the modularity of Cas9-based transcription factors. In this paper we address the problems of specificity and modularity by developing a computational approach for selecting Cas9/gRNA transcription factor/promoter pairs that are maximally orthogonal to each other as well as to the host genome and synthetic circuit components. We validate the method by designing and experimentally testing four orthogonal promoter/repressor pairs in the context of a strong promoter PL from phage lambda. We demonstrate that these promoters can be interfaced by constructing double and triple inverter circuits. To address the problem of modularity we propose and experimentally validate a scheme to predictably incorporate orthogonal CRISPR/Cas9 regulation into a large class of natural promoters.
