Immunohistochemistry results showed that Ki-67 expression was decreased in the tumor tissues of the IRI/CAP-PNA-Lip group compared to the IRI/CAP-Lip group, which suggested that PNA-modified liposomes coloaded with IRICAP had a stronger antitumor cell proliferative effect (Figure 10B). The gene discussed is MKI67; the disease is neoplasm.
