Researchers discover how extrachromosomal DNA circles contribute to the aggressiveness of pancreatic cancer

Extrachromosomal DNA circles are structures that appear floating in the nucleus of cells in some tumours and are associated with a poor prognosis. Now, an international team has studied the mechanism by which they could contribute to the aggressiveness of pancreatic cancer. The circles may contain an oncogene called Myc that promotes growth. Furthermore, their quantity increases or decreases to adapt to the environment. Although they were only observed in 15% of the cases studied, the discovery could open up new possibilities for treatment, according to the authors. The results are published in the journal Nature.
