Abstract: The present invention relates to a composition for regulating cell division by promoting or inhibiting the activity of FCHo1, and a method for regulating cell division using the same. The FCHo1 activity regulator of the present invention targets FCHo1 which functions as an important factor in cell division, and promotes or inhibits the activity thereof, thereby promoting cell division or inhibiting cell division, and thus can be effectively utilized for the treatment of diseases associated with cell division.

Abstract: 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.

Abstract: The present invention relates to a fluorescent dye-labeled glucose analog, and a synthesis method and usage of the same, and more particularly, to novel glucose ? and ? anomers in which a fluorescent dye is labeled by O-1-glycosylation, an asymmetric synthesis method of the anomers, a molecular bioimaging method of the anomers, and a screening method of curing or preventing drugs for diseases related to glucose metabolism.

Abstract: Preparation of novel multifunctional particles and nanomaterials having a useful combination of magnetic and optical properties and biocompatibility. The internalization efficiencies in various in vitro cell studies have been investigated, and the external magnetic motor effect on the floating cells internalized with magnetic nanoparticles were clearly observed, for the first time. The particle surfaces can be derivatized with, for example, DNA or antibodies. The system is stable, versatile, and well-controlled. Novel gene delivery can be achieved using nanoparticles as a carrier.

Abstract: 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.
