FLI1 and Ewing sarcoma: Both fusion proteins FUS-DDIT3 and EWSR1-FLI1 were shown to interact with the SWI/SNF CRCs in MLS 402-91 (myxoid liposarcoma) or EWS TC‐71 (Ewing sarcoma) cell lines, with each line carrying different FET oncogenes with simultaneous lack of expression of normal DDIT3 or FLI1.
