SSX2 and synovial sarcoma: To comprehensively interrogate the transcriptomic changes occurring in synovial sarcoma cells upon TAK-981 treatment, we treated HS-SY-II (harboring the SS18::SSX1 fusion) and SYO1 cells (harboring the SS18::SSX2 fusion) (Appendix Fig. S5) with DMSO or TAK-981 and performed bulk RNA sequencing.
