"Scientists at the Mayo Clinic in Florida have identified the cell's microprocessor that controls cell growth. Called microRNA, this biological controller instructs the cells to stop dividing the moment they have replicated sufficiently, The Telegraph reports. When that happens, microRNA triggers the production of a protein called PLEKHA7, which then breaks the cell bonds and stops growth. In cancerous cells, that process doesn’t work properly.

The doctors were able to switch on cancer in cells by removing microRNAs and preventing them from producing the protein. Then they found they can reverse the process, stopping tumor growth and potentially changing cancer growth. All a patient would need would be an injections containing microRNAs that would reinforce the existing supply in cancer cells.

"We have now done this in very aggressive human cell lines from breast and bladder cancer," Department of Cancer Biology professor Panos Anastasiadis said."
