MKI67 and neoplasm: Immunohistochemistry (IHC) staining results showed that miR-1205 overexpression prominently decreased the numbers of Ki67+ proliferating cells in Hep-2 and KB-3-1 tumors (Fig. 3c), implying that miR-1205 not only attenuates cell proliferation but also suppresses angiogenesis in tumor.
