A Rapid and Precise Mutation-Activated Fluorescence Reporter for Analyzing Acute Mutagenesis Frequency.
Article in Cell chemical biology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 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
Mutagenesis reporters are critical for quantifying genome stability. However, current methods rely on cell survival/death to report mutation, which takes weeks and prevents evaluation of acute or time-dependent changes. Existing methods also have other limitations, such as cell type restrictions. Using our discovery that mCherryFP fluorescence depends on residue Trp98, we replaced this codon with a stop codon to generate a mutation biosensor (termed CherryOFF), with a green fluorescence protein (GFP) as an internal control. We found that the red fluorescence of this biosensor is activated by a specific A/T-G/C nucleotide transition. Compared with the established hypoxanthine phosphoribosyl transferase assay, our reporter has similar or better ability to detect changes of mutation frequency induced by physical/chemical mutagens or manipulation of mutation-related genes. Furthermore, CherryOFF-GFP can report mutagenesis independently of cell-death events, can be adapted to many cell types, and can generate readouts within 1 day for the measurement of acute or time-dependent events.
