Ewing's sarcoma family tumors are dependent on an oncogenic fusion protein, most commonly EWS-FLI1, which interacts with RNA helicase A (RHA) in transcriptional complexes. Erkizan et al. have identified a small molecule that inhibits the interaction of RHA with EWS-FLI1 and impairs the growth of Ewing's sarcoma xenografts in mice. The findings provide evidence that targeting tumor-specific transcription factors may be a feasible approach to treating cancer.
