Placental TRPV2 supports trophoblast function and normal fetal development.
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
While placental functioning arbitrates fetal outcome, the molecular players that underpin normal placental development remain poorly understood. Here, we provide evidence that the Transient Receptor Potential Vanilloid 2 (TRPV2) channel plays an important role in normal placental development, determining fetal size and survival. Its absence severely affects placental morphology, causing fetal growth restriction and embryonic lethality, which was found to be allocated to a non-redundant role in the trophoblast, but not in the embryo. CRISPR/Cas9-mediated Trpv2 deletion in mouse trophoblast stem cells demonstrated that Trpv2 contributes to the differentiation towards Syncytiotrophoblast layer II (SynTII) cells, which was confirmed by the growth restriction phenotype in SynTII-specific Trpv2 knockout animals. Finally, TRPV2 was functionally expressed in human trophoblast cells and enriched in trophoblast populations undergoing syncytial differentiation. Together, our findings identify an important role for TRPV2 during placental development and consequently fetal outcomes.
