Spatiotemporal coupling of caveolae mechanosensing and RhoA-GEFs regulates cell polarity and directional migration.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Migrating cells dynamically adapt their morphogenetic programs in response to microenvironmental changes, requiring coordinated spatiotemporal integration of mechanical and biochemical signals. The plasma membrane, through membrane tension and actin dynamics modulation, is essential for cell motility. Caveolae, small plasma membrane invaginations, act as mechanosensors to buffer tension changes under mechanical stress. Recent evidence suggests a role for caveolae in cell migration. Here, we demonstrate that breast cancer cells exhibit a front-rear asymmetry in caveolae and caveolin-1 scaffolds, which is regulated by membrane tension and is crucial for persistent migration and cell directionality. RhoA-driven cell contraction relies on the spatiotemporally coordinated assembly of caveolae and recruitment of RhoA-GEFs at the cell rear. These results are supported by a physical model establishing a feedback loop between local membrane tension and contractility, through caveolae formation and disruption. Our findings underscore the importance of caveolae mechanosensing in regulating RhoA activation and guiding cell migration.
