Electroporation-based CRISPR/Cas9 Gene Editing in Haliotis Discus Hannai.
Article in Marine biotechnology (New York, N.Y.), 2025. 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
Abalone, a marine mollusk with significant economic and ecological value, plays a crucial role in sustainable aquaculture. The development and application of CRISPR-Cas9 gene-editing technology have opened up a new path for improving breeding efficiency. CRISPR/Cas9-mediated gene editing has been achieved in abalones via microinjection. In this study, a gene encoding myostatin MSTN in H. discus hannai; was selected as target for conducting the CRISPR-Cas9 gene editing experiment in combination with an electroporation delivery system. Our results showed that all three sgRNAs effectively targeted and cleaved the target segment, with sgRNA1 and sgRNA2 exhibiting high in vitro activity. After electroporation, the effects of transfection on embryonic development of fertilized eggs were observed and statistically analyzed. 12.7 ± 5.4% of the fertilized eggs were damaged and deformed after electroporation. Twenty-four hours after electroporation, surviving larvae were collected for DNA extraction and sequencing. Two potential mutations within the target region of MSTN were identified by sequencing. These results provide a reference for the improvement and development of CRISPR-mediated gene editing methods in marine mollusks such as abalones.
