Clonal lineage tracing and parallel multiomics profiling reveal transcriptional heterogeneity induced by ARID1A deficiency

Transcriptional heterogeneity drives malignant progression, yet how it emerges within tumors remains unclear. By combining genetic perturbation and lineage tracing with parallel single-cell multiomics, we tracked the consequences of ARID1A loss within individual clonal lineages....

Plasticity of extrachromosomal DNA segregation during drug adaptation

Uneven segregation during mitosis is a striking feature of extrachromosomal DNA (ecDNA). Because ecDNA lacks a centromere, it is thought to segregate stochastically, generating intratumoral heterogeneity in genomic copy number. Drug treatment can readily change ecDNA copy number,...
