Single-nucleus multiomic analysis of Beckwith-Wiedemann syndrome liver reveals PPARA signaling enrichment and metabolic dysfunction.
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 6 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
Beckwith-Wiedemann Syndrome (BWS) is an epigenetic overgrowth syndrome caused by methylation changes in the human 11p15 chromosomal locus. Patients with BWS may exhibit hepatomegaly, as well as an increased risk of hepatoblastoma. To understand the impact of these 11p15 changes in the liver, we performed a multiomic study [single nucleus RNA-sequencing (snRNA-seq) + single nucleus assay for transposable-accessible chromatin-sequencing (snATAC-seq)] of both BWS-liver and nonBWS-liver tumor-adjacent tissue. Our approach uncovers hepatocyte-specific enrichment of processes related to peroxisome proliferator-activated receptor alpha (PPARA). To confirm our findings, we differentiated a BWS induced pluripotent stem cell model into hepatocytes. Our data demonstrate the dysregulation of lipid metabolism in BWS-liver, which coincides with observed upregulation of PPARA during hepatocyte differentiation. BWS hepatocytes also exhibit decreased neutral lipids and increased fatty acid β-oxidation. We also observe increased reactive oxygen species byproducts in BWS hepatocytes, coinciding with increased oxidative DNA damage. This study proposes a putative mechanism for overgrowth and cancer predisposition in BWS liver due to perturbed metabolism.
