Researchers discover epigenetic status determines metastasis

Posted by in categories: biotech/medical, genetics

Scientists from the German Cancer Research Center (DKFZ) and Heidelberg University have 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. This was also confirmed in experiments with human tumor cells. The results of the study could pave the way for novel diagnostic and therapeutic applications.

The work appears in Nature Cancer.

What makes cancer so dangerous? Cancer cells that leave the primary tumor to reach distant sites of the body where they may grow into daughter tumors, called metastases. While most primary tumors can be effectively treated, metastases are the real danger. Oncologists estimate that more than 90% of all cancer deaths in are due to metastases.
