A Novel White-to-Blue Colony Formation Assay to Select for Optimized sgRNAs.
Article in Molecular biotechnology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
CRISPR/Cas9-mediated genome editing technology consists of a single-guide RNA (sgRNA), and the Cas9 endonuclease has the potential to treat genetic diseases in most tissues and organisms. In this system, the Cas9 protein can be directed to target genomic DNA sequences as "molecular scissors" with the guidance of sgRNAs. However, the target-specific activities of different sgRNAs are highly variable; thus, it is crucial to search for a simple, quick and economical method to screen for optimized sgRNAs with high target specificity. We have adopted and verified a newly developed white-to-blue colony formation assay to quickly screen for sgRNAs optimized for the EphA2 gene, which is highly expressed in hormone-resistant prostate cancer (PC-3) cells. This assay promises to screen for optimized sgRNAs more simply, rapidly, and efficiently. Our results suggest that the white-to-blue colony formation assay might be a useful screening strategy to quickly select for optimized sgRNAs.
