Furthermore, we examined the proliferative index of Ki-67 in the tumor graft by IHC which demonstrated that Ki-67 positive rate was significantly lower (p < 0.01) in the SW1990-miR-329 tumor (45.6%±6.5%) compared with the SW1990-miR-NC tumor (75.6%±5.5%) shown in the Figure 3C. Here, MKI67 is linked to neoplasm.
