Mechano-metabolic feedback connects tissue fluidity to mitochondrial DNA-dependent immunity in breast cancer.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Why some tumors respond to immunotherapy ("hot" tumors) while others remain resistant ("cold" tumors) is a central challenge in oncology. Elevated RAB5A-dependent endocytosis drives tissue fluidization during the transition to invasive breast carcinoma, but its immunological consequences are unclear. Here we show that RAB5A-driven fluidization induces a mechano-metabolic stress response that disrupts the AMPK-AKAP1-DRP1 mitochondrial fission pathway, causing mitochondrial elongation. RAB5A vesicles interact with hyperfused mitochondria and promote BAX/BAK-dependent pore formation, leading to limited mitochondrial outer membrane permeabilization. This sub-lethal event is amplified by palmitoylated GASDERMIN A oligomerization on mitochondria, establishing a positive feedback loop. The resulting release of mitochondrial DNA activates the cGAS-STING innate immune pathway and drives a hyperinflammatory state. Consequently, RAB5A-expressing tumors in immunocompetent mice grow more slowly, show increased immune infiltration, and display enhanced sensitivity to immune-checkpoint blockade in a BAX/BAK-, cGAS/STING-, and mtDNA-dependent manner. These findings connect mechanical stress, mitochondrial dynamics, and innate immunity, revealing strategies to potentiate antitumor immunotherapy.
