UBE2V1 governs aging induced protein aggregation and developmental defects in oocytes and embryos.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
While protein aggregation is a well-documented factor in various age-related diseases, its specific impact on oocyte aging and the molecular mechanisms responsible remain poorly understood. In a mouse model of advanced maternal age, we observe that aging promotes ubiquitinated protein aggregation in oocytes and embryos. Starting with this clue, we identify that the expression of ubiquitin-conjugating enzyme (E2) UBE2V1 in oocyte increases with age and correlates with aggresome formation. We further provide evidence that UBE2V1 positively regulates protein aggregates formation in oocyte under both physiological and stress conditions. Moreover, enhanced UBE2V1 expression mimics the phenotypes observed in aged oocytes. Notably, restoring UBE2V1 expression in aged oocytes and embryos not only alleviates aggresome formation but also partly ameliorates the age-related defects in oocyte maturation and embryo development. Thus, our findings provide a mechanistic link between UBE2V1 expression, protein aggregation and developmental defects in aged oocytes and embryos.
