Ki-67 staining exhibited significantly decreased tumor cell proliferation rates in the cisplatin plus miR-223 Antagomir group compared to the cisplatin alone group (Fig. 7c, d); TUNEL assay showed highest tumor cell apoptosis in the cisplatin plus miR-223 Antagomir group (Fig. 7c, d). The gene discussed is MKI67; the disease is neoplasm.
