Mitochondria are the power plants of cells, and they contain their own genetic material and RNA molecules. Scientists have now discovered that certain modifications in mitochondrial RNA boost the invasive spread of cancer cells by supporting protein synthesis in mitochondria.

When the researchers blocked the responsible RNA modifying enzyme in cancer cells, the number of metastases was reduced. Certain antibiotics that suppress protein synthesis in mitochondria were also able...
