Washington [US]: Variable voltages have been discovered in the membranes of breast cancer cells, revealing information about how the cells grow and spread. The research, led by Imperial College London and The Institute of Cancer Research, London, could help us better understand how cancer cells 'decide' when to multiply and where to spread to. When cells become cancerous, they undergo a series of bioelectric changes. For example, the layer surrounding cells, called the cell membrane, becomes more positively charged than healthy cell membranes.
This new research, published today in Communications Biology, found that as well as the membrane voltage being higher than in healthy cells, it also fluctuates over time - with breast cancer cells behaving much like neurons. The researchers believe this could indicate an electrical communications network between cancer cells that could in future be a target for disruption, creating possible new treatments.
