CRISPR Interference as a Tool to Repress Gene Expression in Haloferax volcanii.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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 date, a plethora of tools for molecular biology have been developed on the basis of the CRISPR-Cas system. Almost all use the class 2 systems since here the setup is the simplest with only one protein and one guide RNA, allowing for easy transfer to and expression in other organisms. However, the CRISPR-Cas components harnessed for applications are derived from mesophilic bacteria and are not optimal for use in extremophilic archaea.Here, we describe the application of an endogenous CRISPR-Cas system as a tool for silencing gene expression in a halophilic archaeon. Haloferax volcanii has a CRISPR-Cas system of subtype I-B, which can be easily used to repress the transcription of endogenous genes, allowing to study the effects of their depletion. This article gives a step-by-step introduction on how to use the implemented system for any gene of interest in Haloferax volcanii. The concept of CRISPRi described here for Haloferax can be transferred to any other archaeon, that is genetically tractable and has an endogenous CRISPR-Cas I systems.
