ETS1 and neoplasm: Not previously studied in EWS, we noted that 18 of 20 EWS tumors (RNA-seq) expressing the highest levels of ETS1 (top quartile) also express median or higher levels of TNS3 (Fig. 7A), and multiple EWS tumor gene expression profiles (microarray-based), show that the expression of ETS1 and TNS3 positively correlate (Fig. 7B, Supplemental Fig. S7A).
