FLI1 and Ewing sarcoma: We also studied another Ewing’s sarcoma cell line, A673: A673 cells depleted of EWS-FLI1 or a negative control both displayed similar sensitivities to olaparib, whereas the original study reported a decreased sensitivity to olaparib when EWS-FLI1 was depleted (Figure 4F; Garnett et al., 2012).
