Acoustic-pressure-driven ultrasonic activation of the mechanosensitive receptor RET and of cell proliferation in colonic tissue.
Article in Nature biomedical engineering, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Ultrasound generates both compressive and shear mechanical forces in soft tissues. However, the specific mechanisms by which these forces activate cellular processes remain unclear. Here we show that low-intensity focused ultrasound can activate the mechanosensitive RET signalling pathway. Specifically, in mouse colon tissues ex vivo and in vivo, focused ultrasound induced RET phosphorylation in colonic crypts cells, which correlated with markers of proliferation and stemness when using hours-long insonication. The activation of the RET pathway is non-thermal, is linearly related to acoustic pressure and is independent of radiation-force-induced shear strain in tissue. Our findings suggest that ultrasound could be used to regulate cell proliferation, particularly in the context of regenerative medicine, and highlight the importance of adhering to current ultrasound-safety regulations for medical imaging.
