Effects of Aging on Z-DNA-Induced Genetic Instability In Vivo.
Article in Genes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Repetitive DNA sequences are abundant in genomes and can adopt alternative DNA structures (i.e., non-B DNA). One such structure, Z-DNA, has been shown to stimulate genetic instability in a variety of organisms, including human cells and mice. Z-DNA-forming sequences are enriched at mutation hotspots in human cancer genomes, implicating them in cancer etiology. Aging is a known risk factor for the development of cancer, and genetic instability is a hallmark of both aging and cancer. However, how aging affects the mutagenic potential of Z-DNA has not yet been investigated. Here, we explored the effects of aging on the mutagenic processing of Z-DNA using a transgenic mouse model. Surprisingly, Z-DNA-induced mutations decreased or remained unchanged with increasing age. Cleavage of Z-DNA was unaffected with increasing age, suggesting that downstream repair processing, such as double-strand break repair processes, may be involved in the age-related changes in Z-DNA-induced mutagenesis in mice.
