      abstract     = {Many cancers are defined by gene fusions that frequently
                      encode oncogenic transcription factors (TFs), such as
                      EWSR1::FLI1 in Ewing sarcoma (EwS). Here, we report that
                      independently to its canonical roles in transcription,
                      EWSR1::FLI1 also functions as an mRNA decay factor,
                      reshaping mRNA stability in EwS. This function participates
                      in EWSR1::FLI1 tumorigenicity and involves interactions of
                      EWSR1::FLI1 with the CCR4-NOT deadenylation complex via its
                      EWSR1-derived low-complexity domain and with the RNA-binding
                      protein HuR/ELAVL1 via its FLI1-derived region. Strikingly,
                      we find that EWSR1::FLI1-mediated mRNA decay antagonizes the
                      normal mRNA protective function of HuR and renders EwS cells
                      highly sensitive to HuR inhibition. Our findings uncover a
                      post-transcriptional function of EWSR1::FLI1 and suggest
                      that targeting mRNA stability mechanisms may offer
                      therapeutic opportunities for EwS.},
