제목 Synthesis of Cell Penetrating Gene Carrier for Breast Cancer-targeted Therapy
초록 A new drug delivery system with cell-penetrating pepetide (CPP) gained greater attention in biomedical filed. CPP facilitates intracellular uptake of target materials such as protein, gene, or macromolecules. Development of therapeutic molecule was greatly thwarted by poor uptake efficiency and low cellular trafficking, which might be overcome by chemical conjugation with CPP. In this study, we conjugated newly identified cellular penetrating peptide, which was found to be highly specific to breast cancer, to cationic gene carrier for achieving enhanced intracellular uptake. Tumor suppressor gene, p53, was delivered with CPP-conjugated gene carrier to breast cancer and its therapeutic efficacy was evaluated. The complex formation with plasmid DNA was performed by gel electrophoresis. Particle size and the surface charge were determined by DLS and zeta potential. The breast cancer transfection and targeting were tested with different breast cancer cell types and xenograft animal model.
