Single-cell RNA–ATAC profiling of Ewing sarcoma identifies multiple fusion-regulated gene regulatory modules, with their prevalence varying across cell lines and within patient tumors.
- Why it matters: Tumor outcomes in Ewing sarcoma vary despite fusion-driven transcription, and it is unclear how plasticity of EWS::FLI1-regulated programs contributes to progression.
- What they did: The study used a single-cell co-assay of RNA and chromatin accessibility (ATAC) sequencing to map regulatory networks in Ewing sarcoma cell lines, then tested whether modules were modifiable by exogenous TGF-β and assessed enrichment in primary patient tumors.
- The result: Regulatory modules were variably enriched across and within tumors, supporting intratumoral heterogeneity and implying that the balance among co-existing transcriptional programs may matter for clinical outcomes and targeted therapy development.
