About ecDNA
Extrachromosomal DNA, or ecDNA, are distinct circular units of DNA lacking centromeres but containing functional genes, including oncogenes, that are separated from tumor cell chromosomes. ecDNA replicate within cancer cells and can be passed to daughter cells asymmetrically during cell division, thereby constituting a primary driver of focal gene amplification and copy number heterogeneity in cancer. By leveraging the plasticity afforded by ecDNA, cancer has the ability to increase or decrease copy number of select oncogenes located on ecDNA to enable survival under selective pressures, including chemotherapy, targeted therapy, immunotherapy, or radiation, making ecDNA one of cancer cells’ primary mechanisms of recurrence and treatment resistance. ecDNA are not found in healthy cells but are present in many solid tumor cancers. They are a key driver of the most aggressive and difficult-to-treat cancers, specifically those characterized by high copy number amplification of oncogenes.
