Playing music to cells makes laryngeal cancer less aggressive, study finds
Mar 4th 2026
A University of Turku team discovered that restoring cellular vibration in vocal cord cancer cells reduced aggressiveness and YAP protein activity, using a bioreactor setup and patient sample analysis that point to a possible targeted drug route.
- Sound-wave vibration that mimics vocal cord movement reduced malignancy of laryngeal cancer cells in the lab.
- Vibration exposure lowered levels of the cancer-promoting protein YAP in those cells.
- Researchers grew cells on a vibrating membrane driven by a loudspeaker and played sounds from a connected mobile phone.
- Analysis of about 200 Finnish patient samples showed higher tissue stiffness and YAP activity correlated with worse outcomes.
- An experimental YAP inhibitor suppressed the cancer in models, suggesting a potential targeted therapy pathway
