PG - 19-28 LID - 10.1080/10611860802438710 [doi] AB - Interleukin-18 (IL-18) is known to reduce melanoma lung metastases through various mechanisms. For the delivery of IL-18 gene into the lung, three different cationic emulsions as non-viral vectors were formulated using the same components of 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), 1,2-dioleoyl-sn-glycero-3-trimethylammonium propane (DOTAP), and Tween 80 with distinct oils. By using the small particle size of physicochemically stable E3, the complex of E3/plasmid DNA encoding IL-18 (16:2.5, w/w) was transfected into lung cancer cells, and the amount of plasmid DNA transferred and the expression of both mRNA and protein for IL-18 were measured. When compared with Lipofectamine/DNA complexes, an E3/DNA complex was less toxic and induced a comparable cellular level of plasmid DNA and expression levels of both mRNA and protein for IL-18. After injecting E3/DNA complexes into mice, the distribution of plasmid DNA was the highest in the lung and the liver. Especially, the administration of E3/DNA complexes induced a more rapid and prolonged distribution of plasmid DNA encoding IL-18 into the lung than that of Lipofectamine/DNA ones. These data demonstrated that cationic emulsion E3 containing castor oil could be useful for a delivery of IL-18 gene targeting the lung as well as the liver without an additional homing device, implying a potential IL-18 delivery system for the treatment of lung cancer.
