제목 Preparation and Evaluation of Hyaluronic acid-coated ternary complex for Targeted Gene delivery  
초록   Branched polyethylenimine(bPEI) was a high gene transfection agent. However, bPEI utilization as gene carrier was limited because of high cytotoxicity. To overcome these obstacle, chitosan was introduced to bPEI by CDI as coupling agent. The chemical structure of chitosan-g-bPEI(CSPEI) was analyzed by 1H-NMR. The ternary complexes with pDNA, CSPEI, and hyaluronic acid (HA) was prepared by electrostatic charge interaction in aqueous phase. Also, its gel retardation assay showed that pDNA was completely bound by CSPEI and HA. In addition, pDNA from ternary complexes was protected against DNase. Beside, its transfection with CD44-receptor overexpressed cancer cell showed that ternary complexes with HA was increased more than binary complexes without HA. These results suggest that ternary complex is superb gene carrier with targeting effect against CD44-receptor overexpressed cancer cell line. (No. NRF-2016H1D5A1910499).
