- International Centre for Genetic Engineering and Biotechnology conducted mouse experiments transplanting a non‑pumping heart, where cancer spread quickly, contrasting with the native beating heart’s resistance.
- Giulio Ciucci co‑authored the paper revealing a protein that senses mechanical forces and downregulates proliferation‑related genes in cancer cells.
- Serena Zacchigna helped uncover the link between mechanical load and epigenetic regulation of tumor growth.
- Michael Fradley of University of Pennsylvania praised the findings as a plausible explanation for the heart’s rarity of cancer and a springboard for new therapies.
- Science published the study on Thursday, detailing the mouse experiments on heart mechanical stress and cancer.
Why it matters: Cancer patients stand to gain from therapies that harness the heart’s thousands‑of‑beats‑per‑day mechanical stress, while researchers get a concrete target for drug design, potentially slowing tumor growth.
