Scientists have discovered a hidden energy mechanism that allows cancer cells to supercharge themselves when under physical stress, potentially explaining why these deadly cells are so resilient.
Story Highlights
- Researchers found cancer cells rapidly mobilize mitochondria to deliver energy surges when physically compressed
- This “first responder” mechanism helps cancer cells survive harsh conditions and repair DNA damage
- The discovery challenges decades of assumptions about mitochondria as static cellular powerhouses
- Scientists identified potential new therapeutic targets to disrupt cancer’s survival advantage
Cancer Cells Deploy Emergency Energy Response
Researchers at the Centre for Genomic Regulation in Barcelona uncovered how cancer cells activate a sophisticated energy delivery system when subjected to mechanical stress. The team observed cancer cells rapidly repositioning their mitochondria to the nucleus, creating what scientists call “nucleus-associated mitochondria” or NAMs. This mechanism delivers concentrated ATP energy directly where cells need it most for DNA repair and survival under pressure.
The discovery emerged from real-time imaging experiments using advanced microscopy techniques on HeLa cancer cells. Dr. Fabio Pezzano, co-first author of the study, noted this represents “a clear sign the cells are adapting to the strain and rewiring their metabolism.” The research team confirmed this phenomenon occurs not only in laboratory cell lines but also in patient breast tumor biopsies, demonstrating clinical relevance.

Overturning Scientific Assumptions About Cellular Energy
This breakthrough challenges the traditional view of mitochondria as stationary cellular batteries. Dr. Sara Sdelci, co-corresponding author, explained the paradigm shift: “It forces us to rethink the role of mitochondria in the human body. They aren’t these static batteries powering our cells, but more like agile first responders that can be summoned in emergency situations when cells are literally pressed to the limit.”
The research reveals cancer cells possess previously unknown adaptive capabilities that help them navigate the crowded, hostile environments within tumors and blood vessels. Cancer cells must squeeze through tight spaces and endure crushing forces as they spread throughout the body. This newly discovered energy mobilization system provides them a critical survival advantage during these challenging journeys.

Implications for Future Cancer Treatment
The discovery opens promising avenues for developing new anti-metastatic therapies. By understanding how cancer cells power themselves through mechanical stress, researchers can potentially design treatments that disrupt this energy delivery system. Targeting the NAM mechanism could make cancer cells more vulnerable to the physical constraints they encounter, reducing their ability to survive and spread.
The study, published in Nature Communications in October 2025, represents a significant advance in cancer biology with potential translational impact. While further research is needed to determine how this mechanism operates across different cancer types, the findings provide a foundation for developing targeted therapies that exploit cancer’s newly understood vulnerabilities. This discovery reinforces the importance of continued investment in basic cancer research to uncover fundamental mechanisms that could lead to more effective treatments.
