Exploring new gene integration sites for gene knock-in by gene-trapping strategy.

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
The knock-in mouse is a powerful tool for biological research, but the stability of expression of an integrated gene strongly depends on where it is integrated in the mouse genome. At present, there are an insufficient number of loci suitable for gene knock-in, such as the Rosa26 locus. Therefore, in this study, we developed an efficient strategy for identifying genome loci suitable for gene knock-in and characterized the properties of such loci for gene integration. For efficient discovery and characterization, we constructed a new gene-trapping vector that enables monitoring of the expression of both trapped and integrated genes using fluorescence. We successfully obtained fluorescent-positive mouse embryonic stem cell (mESC) clones with the vector. Thorough analysis of the expression of fluorescent proteins in chimera embryos generated with the obtained mESC clones, some of the gene-trapped chimera embryos showed stable and ubiquitous expression of the integrated gene. Furthermore, adult mice derived from one of the gene-trapped mESC clones showed ubiquitous expression of the integrated gene in various tissues without any unusual phenotype. This indicated that the identified locus possesses high potential for foreign gene integration. Our strategy allows for efficient discovery and characterization of mouse genome loci for gene integration.
