Cytoplasmic PXR regulates glucose metabolism by binding mRNAs and modulating their stability.
Article in Nature structural & molecular biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
Pregnane X receptor (PXR) is a nuclear receptor considered to be a master transcription factor of xenobiotic metabolism. Here, using enhanced ultraviolet crosslinking and immunoprecipitation, we show that PXR can bind mRNAs in different cancer cell lines and normal liver tissues. PXR-bound mRNAs include genes related to metabolic reprogramming and lipid metabolism. Separately from its known nuclear transcriptional function, cytoplasmic PXR binds and stabilizes mature mRNA containing C+G-enriched sequences through its zinc-finger domain. Mechanistically, cytoplasmic PXR interacts with RNH1, an RNase inhibitor, to regulate RNA stability. In colorectal cancer cells, cytoplasmic PXR facilitates glucose uptake by stabilizing SLC2A1 mRNA. This process further promotes cell proliferation and cancer development. Our study unveils a previously unknown dimension of PXR-mediated gene regulation by characterizing PXR as an RNA-binding protein important for mRNA stability in the cytoplasm.
