ecDNA in Glioblastoma: Spatial Heterogeneity and EGFRvIII Evolution (Part 2)
This Part focuses on how extrachromosomal DNA (ecDNA) shapes spatial heterogeneity and evolution in glioblastoma (GBM). We outline the extreme copy-number gains of drivers (EGFR/PDGFRA/CDK4) on ecDNA, region-to-region response gaps, and ... -
ecDNA in Cancer: Mechanisms of Diversity and Resistance (Part 1)
Extrachromosomal DNA (ecDNA) reshapes oncogene dosage, transcription, phenotypes, and spatial organization, thereby accelerating intratumor heterogeneity and therapy resistance. In Part 1, we briefly introduce non-GBM evidence up front a...
