Epigenetic state and gene expression remain stable after CRISPR/Cas-mediated chromosomal inversions.

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 epigenetic state of chromatin, gene activity and chromosomal positions are interrelated in plants. In Arabidopsis thaliana, chromosome arms are DNA-hypomethylated and enriched with the euchromatin-specific histone mark H3K4me3, while pericentromeric regions are DNA-hypermethylated and enriched with the heterochromatin-specific mark H3K9me2. We aimed to investigate how the chromosomal location affects epigenetic stability and gene expression by chromosome engineering. Two chromosomal inversions of different sizes were induced using CRISPR/Cas9 to move heterochromatic, pericentric sequences into euchromatic regions. The epigenetic status of these lines was investigated using whole-genome bisulfite sequencing and chromatin immunoprecipitation. Gene expression changes following the induction of the chromosomal inversions were studied via transcriptome analysis. Both inversions had a minimal impact on the global distribution of histone marks and DNA methylation patterns, although minor epigenetic changes were observed across the genome. Notably, the inverted chromosomal regions and their borders retained their original epigenetic profiles. Gene expression analysis showed that only 0.5-1% of genes were differentially expressed genome-wide following the induction of the inversions. CRISPR/Cas-induced chromosomal inversions minimally affect epigenetic landscape and gene expression, preserving their profiles in subsequent generations.
