The results have been published in the scientific journal CELL.

Scientists from the German Cancer Research Center (DKFZ) and Medical Faculty Mannheim of the Heidelberg University investigated in mice how spreading tumor cells behave at the site of metastasis: Some tumor cells immediately start to form metastases. Others leave the blood vessel and may then enter a long period of dormancy. What determines which path the cancer cells take is their epigenetic status.

A high-fat, high-sugar diet damages the liver in the long term. Scientists at the German Cancer Research Center (DKFZ) have now identified a characteristic change in the molecular signaling pathways of liver cells in mice that were exposed to such a diet for weeks. It fuels the division activity of hepatocytes and correlates with the risk of patients suffering liver failure after liver surgery.

For the first time, the active substance epifadin has been isolated at the University of Tübingen – Epifadin is produced by specific bacteria in the nose and on the skin of humans, has an antibiotic effect, and is the first example of a previously unknown antimicrobial compound class.
