Scientists at the Mayo Clinic in Florida have successfully turned aggressive breast, lung, and bladder cancer cells back into normal cells. They discovered that microRNAs, which instruct cells to stop division, do not produce the protein PLEKHA7 in cancerous cells. When microRNAs are injected directly into the cancer cells or tumors, the increased levels activate the protein production, thus halting cell division and tumor growth. The researchers hope that this technique will eventually be used to target tumors without the need for chemotherapy or surgery.
