Central Idea: This paper investigates the coordinated inheritance of extrachromosomal DNAs (ecDNAs) in cancer cells, revealing that distinct ecDNA species co-segregate during mitosis, influenced by intermolecular interactions and transcription. This coordinated inheritance impacts oncogene co-amplification, ecDNA specialization, and responses to targeted therapy.
Key Concepts:
- ecDNAs: Circular DNA molecules, common in cancer, driving oncogene amplification and intratumoral heterogeneity.
- ecDNA Species: Distinct ecDNA sequences within a cell, potentially carrying different oncogenes or regulatory elemen ...
