Arid1a regulates bladder urothelium formation and maintenance.
Article in Developmental biology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Epigenetic regulation of gene expression plays a central role in bladder urothelium development and maintenance. ATPase-dependent chromatin remodeling is a major epigenetic regulatory mechanism, but its role in the bladder has not been explored. Here, we show the functions of Arid1a, the largest subunit of the SWI/SNF or BAF chromatin remodeling ATPase complex, in embryonic and adult bladder urothelium. Knockout of Arid1a in urothelial progenitor cells significantly increases cell proliferation during bladder development. Deletion of Arid1a causes ectopic cell proliferation in the terminally differentiated superficial cells in adult mice. Consistently, gene-set enrichment analysis of differentially expressed genes demonstrates that the cell cycle-related pathways are significantly enriched in Arid1a knockouts. Gene-set of the polycomb repression complex 2 (PRC2) pathway is also enriched, suggesting that Arid1a antagonizes the PRC2-dependent epigenetic gene silencing program in the bladder. During acute cyclophosphamide-induced bladder injury, Arid1a knockouts develop hyperproliferative and hyperinflammatory phenotypes and exhibit a severe loss of urothelial cells. A Hallmark gene-set of the oxidative phosphorylation pathway is significantly reduced in Aria1a mutants before injury and is unexpectedly enriched during injury response. Together, this study uncovers functions of Arid1a in both bladder progenitor cells and the mature urothelium, suggesting its critical roles in urothelial development and regeneration.
