The secret DNA circles fueling Pancreatic Cancer’s aggression
A New Player in Pancreatic Cancer
The team found that some pancreatic cancer cells gain a major survival edge by carrying copies of critical cancer genes—such as MYC—on circular pieces of DNA that exist outside chromosomes, the structures that house most of our genetic material. Known as ecDNA, these genetic rings float freely in the cell nucleus, enabling tumour cells to swiftly ramp up gene expression, change their shape, and survive in otherwise hostile environments.
