SOX6: a double-edged sword for Ewing sarcoma.

Developmental pathways play an important role in cancer. We have recently demonstrated that the constitutive activation of the developmental transcription factor SOX6 via the fusion oncoproteinne EWSR1-FLI1 (Ewing sarcoma breakpoint region 1 - Friend leukemia virus integration 1) contributes to the aggressive phenotype of Ewing sarcoma but on another hand provides an opportunity for targeted therapy.
