    • Methods and pharmaceutical compositions for administering protein or gene therapy to tissues or organs having an epithelial cell layer are provided. A protein or nucleic acid encoding the protein is administered to the target tissue or organ in combination with treatment with a delivery enhancing agent which increases the delivery of the interferon or nucleic acid to the cells of the target tissues or organs. The methods and combinations are particularly useful in the treatment of cancers and other conditions responsive to interferon therapy. An exemplary method comprises the transurethral intravesical administration to the bladder of a therapeutically effective amount of a pharmaceutical composition comprising an alpha-interferon or a gene delivery system encoding the interferon and SYN3 or a SYN3 homolog or analog. In the urinary bladder, as much as a 10 to 1000 fold increased in interferon levels and activity may be observed with the use of a SYN3 formulation as opposed to a PBS formulation of the same interferon protein or interferon gene delivery system.
    • 提供了用于对具有上皮细胞层的组织或器官进行蛋白质或基因治疗的方法和药物组合物。 将编码蛋白质的蛋白质或核酸与目标组织或器官联合施用递送增强剂的组合施用,所述递送增强剂增加干扰素或核酸向靶组织或器官的细胞递送。 所述方法和组合在治疗癌症和其它对干扰素治疗有反应的病症方面特别有用。 示例性方法包括向膀胱经尿道膀胱内施用治疗有效量的药物组合物,其包含α-干扰素或编码干扰素和SYN3或SYN3同源物或类似物的基因递送系统。 在膀胱中,与使用相同干扰素蛋白或干扰素基因递送系统的PBS制剂相比,使用SYN3制剂可以观察到高达10至1000倍的干扰素水平和活性。
