(A) Overall survival for mice inoculated with LCLs-WT or LCLs-dBNRF1. The time for 50% survival was 28 days for LCLs-WT and 35 days for LCLs-dBNRF1. (B) Histochemistry of the intraperitoneal tumors stained with hematoxylin and eosin (top), and analyzed by EBER in situ hybridization (middle) and LMP1 immunohistochemistry (bottom). The images shown are representative of two independent experiments with similar results. Scale bar, 100 μm.
