Variant U1 snRNAs contribute to cell cycle and differentiation control of human iPS cells.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 maintenance of stem cell identity, as well as the differentiation of stem cells into any lineage, requires precise regulation of gene expression. Despite intensive research, our understanding of these regulatory processes remains incomplete. Here, we focus on the understudied paralogs of the U1 small nuclear RNA gene known as variant U1 snRNAs. By generating isogenic knockout lines of human induced pluripotent stem cells for different variant U1s, we show that their loss profoundly changes both gene expression and cell cycle profiles. These effects manifest alongside alternative splicing patterns, including those involving recursive splicing sites, and lead to differential availability of stem cell regulators. Together, our results shed new light on the functional roles of variant U1 snRNAs and further our understanding of the programs controlling human pluripotency.
