There is growing evidence that metabolic pathways coupled with external stress factors influence the health of cells and tissues. Many human diseases, including retinal or neurodegenerative diseases, are associated with imbalances in metabolic pathways.

But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
