ETS1 and neoplasm: To validate these results, we transferred OT-I cells transduced with sgNTC, sgEts1, sgBatf or sgEts1 with sgBatf OT-I cells into B16-OVA tumour-bearing mice and found that targeting both Ets1 and Batf reversed the increased accumulation of total and Tex cells (Fig. 3m and Extended Data Fig. 5q).
