After 18 days of implantation, the mice injected with HONE1-EBV-miR-3188 and SUNE1-miR-3188 cells had smaller tumour burdens (Fig. 1g) and displayed lower expression of Ki67 and proliferating cell nuclear antigen (PCNA) in tumour tissues relative to controls (Fig. 1h). This evidence concerns the gene MKI67 and neoplasm.
