Effects of RAD51-stimulatory compound 1 (RS-1) and its vehicle, DMSO, on pig embryo culture.
Article in Reproductive toxicology (Elmsford, N.Y.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Pigs have become an important model for agricultural and biomedical purposes. The advent of genomic engineering tools, such as the CRISPR/Cas9 system, has facilitated the production of livestock models with desired modifications. However, precise site-specific modifications in pigs through the homology-directed repair (HDR) pathway remains a challenge. In mammalian embryos, the use of small molecules to inhibit non-homologous end joining (NHEJ) or to improve HDR have been tested, but little is known about their toxicity. The compound RS-1 stimulates the activity of the RAD51 protein, which plays a key role in the HDR mechanism, demonstrating enhancement of HDR events in rabbit and bovine zygotes. Thus, in this study, we evaluated the dosage and temporal effects of RS-1 on porcine embryo development and viability. Additionally, we assessed the effects of its vehicle, DMSO, during embryo in vitro culture. Transient exposure to 7.5 μM of RS-1 did not adversely affect early embryo development and was compatible with subsequent development to term. Additionally, low concentrations of its vehicle, DMSO, did not show any toxicity to in vitro produced embryos. The transient use of RS-1 at 7.5 μM during in vitro culture seems to be the best protocol of choice to reduce the potentially toxic effects of RS-1 while attempting to improve HDR in the pig. Direct injection of the CRISPR/Cas9 system, combined with strategies to increase the frequency of targeted modifications via HDR, have become an important tool to simplify and accelerate the production of genetically modified livestock models.
