제목 Hyaluronic acid-ceramide (HACE)-based liposomes for enhanced  gene delivery to CD44-positive cancer cells
초록 Hyaluronic acid-ceramide (HACE)-modified liposomes were designed using DOTAP/DOPE for targeted delivery of therapeutic genes to the CD44 receptor-overexpressing cancer cells. Lipoplex was then prepared at different N/P ratios; the gel retardation test showed strong DNA binding affinity of liposomes for targeted gene delivery. Cytotoxicity of liposomes was evaluated by WST assay for different cell lines such as MDA-MB-231 and NIH3T3 cells. We then examined the transfection efficiency of liposomes using luciferase reporter plasmid DNA. We found transfection efficiency of HACE-based liposomes was remarkably higher in case of MDA-MB-231 cells as compared to NIH3T3 cells. Our findings have shown interesting prospective for tumor targeted delivery of therapeutic gene in CD44 receptor-positive cells with less cytotoxic effects.
