ATF2 and neoplasm: Among these genes commonly upregulated genes in SS18-SSX1-expressing eMCs and tumors, such as Sox2 and ApoD, might be downstream targets of the SS18-SSX1 and SWI/SNF axis, and their expression is preserved during oncogenesis, whereas tumor-specific upregulated genes such as Atf2 and Tle1 might require other factors for their expression at the later stage.
