Oncogenes commonly amplify on circular extrachromosomal DNA (ecDNA) molecules in cancer. We show that ecDNA shapes each of the foundational principles of Darwinian evolution — random inheritance by descent, enhanced variation through random segregation, and selection — and thereby promotes rapid genome change, treatment resistance and poor outcomes for patients with cancer.

Nathanson, D. A. et al. Targeted therapy resistance mediated by dynamic regulation of extrachromosomal mutant EGFR DNA. Science 343, 72–76 (2014). This paper demonstrates that glioblastoma cells can reversibly modulate their EGFR oncogene copy number to develop resistance to treatment, because the oncogene was amplified on ecDNA.
Turner, K. M. et al. Extrachromosomal oncogene amplification drives tumour evolution and genetic heterogeneity. Nature 543, 122–125 (2017). This paper shows that oncogene amplification on ecDNA is common in cancer cell lines and that it drives diversity and high oncogene copy numbers.
Kim, H. et al. Extrachromosomal DNA is associated with oncogene amplification and poor outcome across multiple cancers. Nat. Genet. 52, 891–897 (2020). This paper demonstrates that oncogene amplification on ecDNA is common in many of the most aggressive cancer types and that it is associated with shorter survival of patients.
Wu, S. et al. Circular extrachromosomal DNA promotes accessible chromatin and high oncogene expression. Nature 575, 699–703 (2019). This paper demonstrates the topology and altered chromatin structure of ecDNA, revealing the impact of its unique topology on oncogenic transcription.
Hung, K. L. et al. ecDNA hubs drive cooperative intermolecular oncogene expression. Nature 600, 731–736 (2021). This paper describes how ecDNA hubs drive altered oncogene transcription, including through intermolecular interactions.
