SUV39H1 and neoplasm: Mice that received Suv39h1-KO OT-1 T cells controlled tumor growth better than mice that received littermate WT OT-1 T cells (Supplementary Fig. 1B), demonstrating that Suv39h1 deficiency in CD8+ T cells augments their anti-tumor potential in the absence of any other Suv39h1-defective cell type.
