apoptin, a protein that is derived from the chicken anemia virus, has been shown to possess cancer-specific cytotoxicity effects.18-21 In the present study, we aimed to investigate whether constructing a lentiviral vector encoding a green fluorescent protein-apoptin fusion gene (LV-GFP-AP) that can efficiently deliver apoptin into leukemic cells could be an effective strategy to reduce the survival of the neoplastic cells. Here, DHCR7-DT is linked to cancer.
