Convergent evolution of H4K16ac-mediated dosage compensation in the ZW species Artemia franciscana.
Article in PLoS genetics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Sex chromosomes impact chromatin organization and histone modification dynamics differently between males and females, particularly those involved in dosage compensation (DC). The evolutionary diversity, as well as the tissue- and age-dependent variations of DC mechanisms are incompletely understood. Here, we investigate the occurrence of histone H4 lysine 16 acetylation (H4K16ac), previously known for its role in sex chromosome DC in the male-heterogametic fruit fly Drosophila melanogaster and the green anole lizard Anolis carolinensis. By sampling multiple arthropods, we find the convergent evolution of H4K16ac for DC in a female-heterogametic (ZW) species, the crustacean Artemia franciscana. CUT&Tag analysis demonstrates that H4K16ac is confined to the non-recombining stratum of the Z chromosome in females. H4K16ac-mediated DC is established during embryogenesis. In aged individuals, we observe an overall decline in nuclear organization, disrupted H4K16ac territories and increased variability in local acetylation levels on the female Z chromosome. Our findings shed light on the evolutionary diversity of DC across species and raise the possibility of sex-specific histone acetylation contributing to male-female differences in lifespan.
