Novel fluorescent-based reporter cell line engineered for monitoring homologous recombination events.
Article in PloS one, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Homologous recombination (HR) faithfully restores DNA double-strand breaks. Defects in this HR repair pathway are associated with cancer predisposition. In genetic engineering, HR has been used extensively to study gene function and it represents an ideal method of gene therapy for single gene disorders. Here, we present a novel assay to measure HR in living cells. The HR substrate consisted of a non-fluorescent 3' truncated form of the eGFP gene and was integrated into the AAVS1 locus, known as a safe harbor. The donor DNA template comprised a 5' truncated eGFP copy and was delivered via AAV particles. HR mediated repair restored full-length eGFP coding sequence, resulting in eGFP+ cells. The utility of our assay in quantifying HR events was validated by exploring the impact of the overexpression of HR promoters and the siRNA-mediated silencing of genes known to play a role in DNA repair on the frequency of HR. We conclude that this novel assay represents a useful tool to further investigate the mechanisms that control HR and test continually emerging tools for HR-mediated genome editing.
