Ki67 and Tunel staining of the tumor/liver sections showed that the control group contained more Ki67-positive and less Tunel-positive cells than those of the Dox, miR-26 and Dox plus miR-26 groups and that Dox plus miR-26 group had fewer Ki67-positive and more Tunel-positive cells than the Dox and miR-26 groups (Figures 6f and g), respectively. Here, MKI67 is linked to neoplasm.
