Scientists Successfully Turn Human Cancer Cells Back to Normal in Process That Could ‘Switch Off’ Disease

This sounds promising, U.S. scientists successfully turn human cancer cells back to normal in process that could ‘switch off’ disease

"The scientists discovered that the glue which holds cells together is regulated by biological microprocessors called microRNAs. When everything is working normally, the microRNAs instruct the cells to stop dividing when they have replicated sufficiently. They do this by triggering production of a protein called PLEKHA7 which breaks the cell bonds. But in cancer that process does not work.

Scientists discovered they could switch on cancer in cells by removing the microRNAs from cells and preventing them from producing the protein. And, crucially, they found that they could reverse the process, switching the brakes back on and stopping cancer."
