Kdm4d mutant mice show impaired sperm motility and subfertility.
Article in The Journal of reproduction and development, 2024. 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
Regulation of gene expression through histone modifications underlies cell homeostasis and differentiation. Kdm4d and Kdm4dl exhibit a high degree of similarity and demethylate H3K9me3. However, the physiological functions of these proteins remain unclear. In this study, we generated Kdm4dl mutant mice and found that Kdm4dl was dispensable for mouse development. However, through the generation of Kdm4d mutant mice, we unexpectedly found that Kdm4d mutant male mice were subfertile because of impaired sperm motility. The absence of Kdm4d was associated with an altered distribution of H3K9me3 in round spermatids, suggesting that the Kdm4d-mediated adjustment of H3K9me3 levels is required to generate motile sperm. Further analysis revealed that the absence of Kdm4d did not affect the functionality of sperm nuclei in generating offspring. As KDM4D is specifically expressed in the human testes, our results suggest that changes in KDM4D expression or its activity may be a risk factor for human infertility.
