제목 Targeted delivery of Cell PenetratingMicroRNAgene carrier for Breast Cancer therapy
초록 Drug delivery system with cell-penetrating pepetide (CPP) has gained greater attention in biomedical field. 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 and conjugated to cationic gene carrier for achieving enhanced intracellular uptake. MicroRNA to be delivered with CPP-conjugated gene carrier for the treatment of breast cancer. The complex formation with plasmid DNA was checked by gel electrophoresis. Particle size and the surface charge were determined by DLS and zeta potential. The transfection efficiency and cytotoxicity of the carrier has been studied with various breast cancer cell lines.
