Ki67 immunohistochemical staining of subcutaneous xenotransplanted tumor tissues further confirmed the positive rate of Ki67 was greater in tumor tissues of mice injected with miR-410 overexpression stable cells versus that was smaller in tumor tissues of mice injected with miR-410 knock-down stable cells compared with mice injected with their respective control cells (Figure 2J). The gene discussed is MKI67; the disease is neoplasm.
