Immunohistochemistry analysis also revealed that tumours derived from miR-129-5p-overexpressing N3 showed increased miR-129-5p, decreased Wnt5a expression (Fig. 7g, left), a lower proliferation index as demonstrated by Ki-67 staining and significantly lower levels of CD31 expression (Fig. 7g, right). The gene discussed is MKI67; the disease is neoplasm.
