Dysregulated transcription processes in Ewing sarcoma
Abstract Ewing sarcoma (EwS) is a pediatric and young adult cancer that is driven by the EWSR1-FLI1 translocation. Despite decades of work, this cancer is still an enigma, with poorly understood biology and no targeted treatments. Our recent work published in Nature demonstrated a previously overlooked consequence of EWSR1-FLI1, that this fusion causes hyperphosphorylated RNA polymerase II (pRNAPII) due to loss of EWSR1 inhibition of CDK7 and CDK9. We observed high levels of transcription, with high levels of R-loops present in locations that R-loops normally (physiologically) occur. Based upon these findings, we began to reconsider cellular phenotypes of EwS to identify the molecular basis…
