Role of PRC2 in the stochastic expression of Aire target genes and development of mimetic cells in the thymus.
Article in The Journal of experimental medicine, 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
The transcriptional targets of Aire and the mechanisms controlling their expression in medullary thymic epithelial cells (mTECs) need to be clarified to understand Aire's tolerogenic function. By using a multi-omics single-cell approach coupled with deep scRNA-seq, we examined how Aire controls the transcription of a wide variety of genes in a small fraction of Aire-expressing cells. We found that chromatin repression by PRC2 is an important step for Aire to achieve stochastic gene expression. Aire unleashed the silenced chromatin configuration caused by PRC2, thereby increasing the expression of its functional targets. Besides this preconditioning for Aire's gene induction, we demonstrated that PRC2 also controls the composition of mTECs that mimic the developmental trait of peripheral tissues, i.e., mimetic cells. Of note, this action of PRC2 was independent of Aire and it was more apparent than Aire. Thus, our study uncovered the essential role of polycomb complex for Aire-mediated promiscuous gene expression and the development of mimetic cells.
