摘要： Disclosed herein is a gene therapeutic agent and pharmaceutical composition for the prevention and treatment of lung cancer. For aerosol delivery, chemically synthesized polyester amine is used as a carrier in the gene therapeutic agent. The polyester amine/Akt1 siRNA complex is found to be effectively delivered to the lungs of K-ras null mice through a nose-only inhalation system and to significantly suppress lung cancer progression as denoted by gene delivery efficiency and inhibition of Akt-related signals and cell cycle. Thus, the aerosol delivery of polyester amine-mediated Akt1 siRNA is provided as an effective model for noninvasive gene therapy.

摘要： The present invention relates to a biodegradable polysorbitol-based osmotically active transporter (PSOAT) and gene therapy using the same as a gene carrier. The biodegradable polysorbitol-based osmotically active transporter (PSOAT) of the present invention includes a sorbitol skeleton, which imparts an osmotic pressure to the cell membrane to improve membrane permeability, thereby exhibiting remarkably improved transfection efficiency. Further, the polysorbitol-based osmotically active transporter of the present invention exhibits high DNA binding ability, effectively protects DNA from nuclease, exhibits physicochemical properties suitable for use as a gene carrier, and has very low cytotoxicity in vitro and in vivo, thereby capable of being used as a gene carrier for gene therapy.
