Figure 3. EBV-miR-BART8-3p promotes NPC radioresistance in vivo.

(A) Xenograft tumors generated by subcutaneous implantation of 5-8F cells were excised on Day 14 after reaching a volume of 200 mm³. The NC-IR and BART8-3p-IR groups were exposed to 2 Gy IR every 2 days and the volume (B) and weight (C) of tumors are shown. Histologic evaluation of tumor structure (D).
