Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, researchers have discovered a new function of mitochondria: they set off molecular alarms when cells are exposed to stress or chemicals that can damage DNA, such as chemotherapy. The results could lead to new cancer treatments that prevent tumors from b […]
