Ewing sarcoma (ES) is driven by the oncogenic fusion-protein EWSR1::FLI1. Here the authors identify that a galactosyltransferase C1GALT1 stabilizes Smoothened protein to activate Hedgehog signaling and promote EWSR1::FLI1 transcription in ES cells, which could be therapeutically targeted by an anti-fungal drug itraconazole that inhibits C1GALT1.
