Identification of Extrachromosomal Linear microDNAs Interacted with microRNAs in the Cell Nuclei.

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
Extrachromosomal DNA exists in two forms: Covalently closed circular and linear. While diverse types of circular extrachromosomal DNA have been identified with validated in vivo functions, little is known about linear extrachromosomal DNA. In this study, we identified small, single-stranded linear extrachromosomal DNAs (SSLmicroDNAs) in the nuclei of mouse hearts, mouse brains, HEK293, and HeLa cells. We used a pull-down system based on the single-stranded DNA binding protein RecAf. We found that SSLmicroDNAs aligned predominantly to intergenic and intragenic regions of the genome, owned a variety of single nucleotide polymorphism sites, and strongly associated with H3K27Ac marks. The regions were tens to hundreds of nucleotides long, periodically separated by AT, TT, or AA dinucleotides. It has been demonstrated that SSLmicroDNAs in the nuclei of normal cells target microRNAs, which regulate biological processes. In summary, our present work identified a new form of extrachromosomal DNAs, which function inside nuclei and interact with microRNAs. This finding provides a possible research field into the function of extrachromosomal DNA.
